QUESTION 1
zone1 is a non-global zone that has been configured and installed.
zone1 was taken down for maintenance, and the following command was run:
zoneadm -z zone1 mark incomplete
The following information is displayed when listing the zones on your system:
Which task needs to be performed before you can boot zone1?
A.
B.
C.
D.
The zone needs to be installed.
The zone needs to be brought to the ready state.
The zone needs to be uninstalled and reinstalled.
The zone needs to be brought to the complete state.
Correct Answer: C
Section: (none)
Explanation
Explanation/Reference:
Explanation:
If administrative changes on the system have rendered a zone unusable or inconsistent, it is possible to change the state of an installed zone to incomplete.
Marking a zone incomplete is irreversible. The only action that can be taken on a zone marked incomplete is to uninstall the zone and return it to the configured
state.

QUESTION 3
Which best describes the svc:/system/boot-config service?
A.
B.
C.
D.
It is used to change the milestone on a system.
It is used to set the default run level of the system.
It provides the parameters used to set the system to automatically perform a fast or slow reboot.
When the service is enabled, the system performs a fast reboot by default; when it is disable the system performs a slow reboot by default.
Correct Answer: C
Section: (none)
http://www.gratisexam.com/
Explanation
Explanation/Reference:
Explanation:
Starting with the Oracle Solaris 11 Express release, Fast Reboot is supported on the SPARC platform, as well as the x86 platform. On both platforms, this feature is
controlled by the SMF and implemented through a boot configuration service, svc:/system/boot-config. The boot-config service provides a means for setting or
changing the default boot configuration parameters.
Real 3
Oracle 1z0-821 Exam
The fastreboot_default property of the boot-config service enables an automatic fast reboot of the system when either the reboot or the init 6 command is used.
When the config/fastreboot_default property is set to true the system automatically performs a fast reboot, without the need to use the reboot -f command. By
default, this property's value is set to false on the SPARC platform and to true on the x86 platform.

What determines which bits in an IP address represent the subnet, and which represent the host?
A.
B.
C.
D.
E.
Subnet
unicast
netmask
multicast
broadcast
Correct Answer: C
Section: (none)
Explanation
Explanation/Reference:
Explanation:
A subnetwork, or subnet, is a logically visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. The
routing prefix of an address is written in a form identical to that of the address itself. This is called the network mask, or netmask, of the address. For example, a
specification of the most- significant 18 bits of an IPv4 address, 11111111.11111111.11000000.00000000, is written as 255.255.192.0.
QUESTION 8
You are troubleshooting a newly installed desktop Oracle Solaris 11 system with a single network interface. From this system, you can connect to other systems
within the company intranet, but cannot access any external services (such as websites and email), even when using IP addresses.
Examining the routing table confirms that the default route to 192.168.1.1 is missing. DHCP is not used at this site. Which two commands will temporarily mid
permanently configure the default route?
A. ipadm set-gateway 192.168.1.1
B. route add default 192.168.1.1
C. ipadm set-default 192.168.1.1
http://www.gratisexam.com/
D. dladm route-add d 192.168.1.1
E. echo 192.168.1.1 >/etc/gateway
F. echo 192.168.1.1 >/etc/defaultrouter
Correct Answer: BF
Section: (none)
Explanation
Explanation/Reference:
Real 9
Oracle 1z0-821 Exam
Explanation:
B: Setting the default route on Solaris is easy. If you are trying to just set the route temporarily you can use the route command:
Route add default <ipaddress>
Example:
Route add default 192.168.1.1
Note: Route command manipulates the kernel routing tables. Routing is the process of forwarding a packet from one computer to another. It is based on the IP
address in the IP packet header and netmask.
F: If you want the route to be persisted when you reboot the system, you will need to set the route in the /etc/defaultrouter file.
/etc/defaultrouter
Example:
Echo 192.168.1.1 > /etc/defaultrouter
QUESTION 9
You want the system to generate an email notification each time one of the services has changed its state. Which option would send an email message to the
system administrator whenever a service changes to the maintenance state?
A. Use the setsc command in ALOM to enable the mail alerts to be sent to a specified email address whenever the fault management facility detects a service
change to the maintenance state.
B. Make an entry in the /etc/syslog.conf file to instruct syslogd to send an email alert when it receives a message from the SMF facility that a service has changed
to the maintenance state.
C. Use the svccfg setnotify command to create a notification and send an email when a service enters the maintenance state.
http://www.gratisexam.com/
D. Use the scvadm command to enable the notification service. Set the g maintenance option on the netnotify service to send an email when a service enters the
maintenance state.
Correct Answer: C
Section: (none)
Explanation
Explanation/Reference:
Real 10
Oracle 1z0-821 Exam
Explanation:
This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to
use either SMTP or SNMP. Normally, you would only select SNMP if you already have SNMP configured for some other reason.
By default, SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring, you can configure additional traps for other state transitions.
1. Become an administrator or assume a role that includes the Service Management rights profile.
2. Set notification parameters.
Example:
The following command creates a notification that sends email when transactions go into the maintenance state
# /usr/sbin/svccfg setnotify -g maintenance mailto:sysadmins@example.com

You need to configure an ISCSI target device on your x86 based Oracle Solaris II system. While configuring the iSCSI device, the following error is displayed:
bash: stmfadm: command not found
Which option describes the solution to the problem?
A.

Start the iSCSI target daemon on this system.
Correct Answer: C
Section: (none)
Explanation
Explanation/Reference:
Real 14
Oracle 1z0-821 Exam
Explanation:
STMF Manages transactions, such as context and resources for Small Computer System Interface (SCSI) command execution, and tracking logical unit and port
providers. STMF also handles logical unit mappings, allocating memory, recovering failed operations, enumeration, and other necessary functions of an I/O stack.
STMF is controlled by stmfadm, and stmfadm is the majority of the commands you will be using to administer COMSTAR (COmmon Multiprotocl Scsi TARget).
Install the packages you need for COMSTAR with iSCSI and reboot:
# pfexec pkg install storage-server
# pfexec pkg install SUNWiscsit
# shutdown -y -i6 -g0
Note: You can set up and configure a COMSTAR Internet SCSI (iSCSI) target and make it available over the network. The iSCSI features can work over a normal
Internet connection (such as Ethernet) using the standard iSCSI protocol. The iSCSI protocol also provides naming and discovery services, authentication services
using CHAP and RADIUS, and centralized management through iSNS.
The COMSTAR target mode framework runs as the stmf service. By default, the service is disabled. You must enable the service to use COMSTAR functionality.
You can identify the service with the svcs command. If you have not rebooted the server since installing the group/feature/storage-server package, the service
http://www.gratisexam.com/
might not be enabled correctly.

Explanation:
Test the remote connection with traceroute.
The Internet is a large and complex aggregation of network hardware, con- nected together by gateways. Tracking the route one's packets follow (or finding the
miscreant gateway that's discarding your packets) can be difficult. traceroute utilizes the IP protocol `time to live' field and attempts to elicit an ICMP
TIME_EXCEEDED response from each gateway along the path to some host.
This program attempts to trace the route an IP packet would follow to some internet host by launching UDP probe packets with a small ttl (time to live) then listening
for an ICMP "time exceeded" reply from a gateway.

C: -e Edits a copy of the current user's crontab file, or creates an empty file to edit if crontab does not exist. When editing is complete, the file is installed as the
user's crontab file. If a username is given, the specified user's crontab file is edited, rather than the current user's crontab file; this can only be done by a user with
the solaris.jobs.admin authorization. The environment variable EDITOR determines which editor is invoked with the -e option. The default editor is ed(1). All crontab
jobs should be submitted using crontab. Do not add jobs by just editing the crontab file, because cron is not aware of changes made this way.

How to Set Up Email Notification of SMF Transition Events This procedure causes the system to generate an email notification each time one of the services or a
selected service has a change in state. You can choose to use either SMTP or SNMP. Normally, you would only select SNMP if you already have SNMP configured
for some other reason.
Real 32

By default, SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring, you can configure additional traps for other state transitions.
1. Become an administrator or assume a role that includes the Service Management rights profile.'
2. Set notification parameters.
Example 1:
The following command creates a notification that sends email when transactions go into the maintenance state.
# /usr/sbin/svccfg setnotify -g maintenance mailto:sysadmins@example.com
Example 2:
The following command creates a notification that sends email when the switch service goes into the online state.
# /usr/sbin/svccfg -s svc:/system/name-service/switch:default setnotify to-online \ mailto:sysadmins@example.com
Note: The svccfg command manipulates data in the service configuration repository. svccfg can be invoked interactively, with an individual subcommand, or by
specifying a command file that contains a series of subcommands.
Changes made to an existing service in the repository typically do not take effect for that service until the next time the service instance is refreshed.

Explanation/Reference:
Explanation:
The graphical installer is officially known as the "Live Media." This means that Oracle Solaris can be booted into RAM, causing zero impact on your existing
operating system. After it is loaded, you are free to experiment with Oracle Solaris to determine whether it is something you would like to install to your system.
Real 38
Oracle 1z0-821 Exam
You can download Oracle Solaris 11 Live Media for x86, which is an approximately 800 MB image file, and use a DVD burner to create the disk, or you can use the
ISO image directly in a virtual machine or through the Oracle Integrated Lights Out Manager (ILOM) Remote Console.
The Live Media is not intended for long-term use. For example, any changes that you make to the system are lost when the system is shut down. Therefore, the
next logical step is to install Oracle Solaris on the system, which the Live Media makes easy by placing an Install Oracle Solaris icon right on the desktop. But
before we head down that road, let's step back a bit and consider the installation options.
Note: The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11 environment without installing it on a system. The system boots

off the media directly allowing administrators to start the installer should they choose to install it to a system.

Which two options are characteristics of a fast reboot?
Real 43
Oracle 1z0-821 Exam
A. A fast reboot bypasses grub.
B. A fast reboot cannot be used after a system panic on the x86 platform.
C. A fast reboot can only be executed on the SPARC platform when the config/fastreboot_default property for the svc:/system/boot-config:default service is set to
true.
D. A fast reboot uses an in-kernel boot loader to load the kernel into memory.
E. A fast reboot is the default on all platforms.
Correct Answer: CD
Section: (none)
Explanation
Explanation/Reference:
http://www.gratisexam.com/
Explanation:
C: To change the default behavior of the Fast Reboot feature on the SPARC platform, so that a fast reboot is automatically performed when the system reboots,
see below.
The following example shows how to set the property's value to true on the SPARC platform, so that a fast reboot is initiated by default:
# svccfg -s "system/boot-config:default" setprop config/fastreboot_default=true # svcadm refresh svc:/system/boot-config:default
D: Fast Reboot implements an in-kernel boot loader that loads the kernel into memory and then switches to that kernel.
The firmware and boot loader processes are bypassed, which enables the system to reboot within seconds.
The Fast Reboot feature is managed by SMF and implemented through a boot configuration service, svc:/system/boot-config. The boot-config service provides a
means for setting or changing the default boot configuration parameters. When the config/fastreboot_default property is set to true, the system performs a fast
reboot automatically, without the need to use the reboot -f command. This property's value is set to true on the x86 platform. For task-related information, including
how to change the default behavior of Fast Reboot on the SPARC platform, see Accelerating the Reboot Process on an x86 Based System.
Note: One new feature, called Fast Reboot, will allow the system to boot up without doing the routine set of hardware checks, a move that can make system boot
times up to two-and-a-half times faster, Oracle claimed. This feature can be handy in that an administrator applying a patch or software update across thousands of
Solaris deployments can reboot them all the more quickly.

UFS quotas enable system administrators to control the size of file systems. Quotas limit the amount of disk space and the number of inodes, which roughly
corresponds to the number of files, that individual users can acquire. For this reason, quotas are especially useful on the file systems where user home directories
reside. As a rule, the public and /tmp file systems usually do not benefit significantly by establishing quotas.

Correct Answer: C
Section: (none)
Explanation
Explanation/Reference:
Explanation:
You might need to replace a disk in the root pool for the following reasons:
The root pool is too small and you want to replace it with a larger disk
The root pool disk is failing. In a non-redundant pool, if the disk is failing so that the system won't boot, you'll need to boot from an alternate media, such as a CD or
the network, before you replace the root pool disk.
http://www.gratisexam.com/
In a mirrored root pool configuration, you might be able to attempt a disk replacement without having to boot from alternate media. You can replace a failed disk by
using the zpool replace command.
Some hardware requires that you offline and unconfigure a disk before attempting the zpool replace operation to replace a failed disk.
For example:
# zpool offline rpool c1t0d0s0
# cfgadm -c unconfigure c1::dsk/c1t0d0
<Physically remove failed disk c1t0d0>
<Physically insert replacement disk c1t0d0>
# cfgadm -c configure c1::dsk/c1t0d0
# zpool replace rpool c1t0d0s0
# zpool online rpool c1t0d0s0
# zpool status rpool
<Let disk resilver before installing the boot blocks>

Note: cat - concatenate files and print on the standard output
Note #1: A list is a sequence of one or more pipelines separated by one of the operators `;', `&', `&&', or `||', and optionally terminated by one of `;', `&', or a newline.
Of these list operators, `&&' and `||' have equal precedence, followed by `;' and `&', which have equal precedence.
AND and OR lists are sequences of one or more pipelines separated by the control operators `&&' and `||', respectively. AND and OR lists are executed with left
associativity.
An AND list has the form
command1 && command2
command2 is executed if, and only if, command1 returns an exit status of zero.
An OR list has the form
command1 || command2
command2 is executed if, and only if, command1 returns a non-zero exit status.
The return status of AND and OR lists is the exit status of the last command executed in the list.
Note #2 (on exit status): Zero means command executed successfully, if exit status returns non- zero value then your command failed to execute.

Subnets are created by using________.
A.
B.
C.
D.
subnet
netmask
unicast
broadcast
Correct Answer: B
Section: (none)
Explanation
Explanation/Reference:
Explanation:
The process of subnetting involves the separation of the network and subnet portion of an address from the host identifier. This is performed by a bitwise AND
operation between the IP address and the (sub)network prefix. The result yields the network address or prefix, and the remainder is the host identifier.
The routing prefix of an address is written in a form identical to that of the address itself. This is called the network mask, or netmask, of the address. For example,
a specification of the most- significant 18 bits of an IPv4 address, 11111111.11111111.11000000.00000000, is written as 255.255.192.0.

The public host key supplied by oracle is not known to the host solaris.
Correct Answer: BD
Section: (none)
Explanation
Explanation/Reference:
Explanation:
The fingerprints are used to guard against man in the middle attacks. Since ssh logins usually work over the internet (an insecure connection), someone could
hijack your connection. When you try to log into yourmachine.com, he could get "in the middle" and return your challenge as if he was yourmachine.com. That way,
he could get hold of your login password.
To make this attack harder, ssh stores the fingerprint of the server's public key on the first connection attempt. You will see a prompt like:
The authenticity of host 'eisen (137.43.366.64)' can't be established. RSA key fingerprint is cf:55:30:31:7f:f0:c4:a0:9a:02:1d:1c:41:cf:63:cf.
Are you sure you want to continue connecting (yes/no)
When you enter yes, ssh will add the fingerprint to your known_hosts file. you will see
Code:
Warning: Permanently added 'eisen, 137.43.366.64' (RSA) to the list of known hosts.
The next time you login, ssh will check whether the host key has changed. A changing host key usually indicates a man in the middle attack, and ssh refuses to
connect.

Oracle 1z0-821 Exam
E. Simple Authentication and Security Layer (SASL) provides a mechanism to authenticate and encrypt access to local file system data.
Correct Answer: AE
Section: (none)
Explanation
Explanation/Reference:
Explanation:
A: Pluggable Authentication Modules (PAM) are an integral part of the authentication mechanism for the Solaris. PAM provides system administrators with the ability
and flexibility to choose any authentication service available on a system to perform end-user authentication.
By using PAM, applications can perform authentication regardless of what authentication method is defined by the system administrator for the given client.
PAM enables system administrators to deploy the appropriate authentication mechanism for each service throughout the network. System administrators can also
select one or multiple authentication technologies without modifying applications or utilities. PAM insulates application developers from evolutionary improvements
to authentication technologies, while at the same time allowing deployed applications to use those improvements.
PAM employs run-time pluggable modules to provide authentication for system entry services.
E: The Simple Authentication and Security Layer (SASL) is a method for adding authentication support to connection-based protocols. Simple Authentication and
Security Layer (SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols,
in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL. Authentication mechanisms can also
support proxy authorization, a facility allowing one user to assume the identity of another. They can also provide a data security layer offering data integrity and data
confidentiality services. DIGEST-MD5 provides an example of mechanisms which can provide a data-security layer. Application protocols that support SASL
typically also support Transport Layer Security (TLS) to complement the services offered by SASL.

QUESTION 61
Which three of the components would degrade performance if used in a ZFS storage pool, and are not recommended configurations?
A.
B.
C.
D.
E.
F.
a file on a UFS file system
a Veritas Volume Manager (VxVM) volume
a LUN in a hardware RAID array
a disk slice from an SMI labeled disk
a Solaris Volume Manager (SVM) volume
an EDI disk
Correct Answer: ABE
Section: (none)
Explanation
Explanation/Reference:
Explanation:
A: ZFS also allows you to use UFS files as virtual devices in your storage pool. This feature is aimed primarily at testing and enabling simple experimentation, not
for production use. The reason is that any use of files relies on the underlying file system for consistency. If you create a ZFS pool backed by files on a UFS file
system, then you are implicitly relying on UFS to guarantee correctness and synchronous semantics.
However, files can be quite useful when you are first trying out ZFS or experimenting with more complicated layouts when not enough physical devices are present.
All files must be specified as complete paths and must be at least 64 Mbytes in size.
B, E: You can construct logical devices for ZFS using volumes presented by software-based volume managers, such as Solaris Volume Manager (SVM) or Veritas
Volume Manager (VxVM). However, these configurations are not recommended. While ZFS functions properly on such devices, less-than-optimal performance
might be the result.

Network interfaces provide the connection between the system and the network. These interfaces are configured over data links, which in turn correspond to
instances of hardware devices in the system.
In the current model of the network stack, interfaces and links on the software layer build on the devices in the hardware layer. More specifically, a hardware device
instance in the hardware layer has a corresponding link on the data-link layer and a configured interface on the interface layer. This one-to-one relationship among
the network device, its data link, and the IP interface is illustrated in the figure that follows.

Note shutdown:
Shutdown is executed by the super user to change the state of the machine. In most cases, it is used to change from the multi-user state (state 2) to another state.
By default, shutdown brings the system to a state where only the console has access to the operating system. This state is called single-user.

Explanation:
A kernel panic is a type of error that occurs when the core (kernel) of an operating system receives an instruction in an unexpected format or when it fails to handle
properly. A kernel panic can also follow when the operating system can't recover from a different type of error. A kernel panic can be caused by damaged or
incompatible software or, more rarely, damaged or incompatible hardware.
When a server kernel panics it abruptly halts all normal system operations. Usually, a kernel process named panic() outputs an error message to the console and
stores debugging information in nonvolitile memory to be written to a crash log file upon restarting the computer. Saving the memory contents of the core and
associated debugging information is called a "core dump."

Oracle Solaris provides predefined rights profiles. These profiles, listed in the /etc/security/prof_attr, can be assigned by the root role to any account. The root role is
assigned all privileges and all authorizations, so can perform all tasks, just as root can when root is a user.
To perform administrative functions, you open a terminal and switch the user to root. In that terminal, you can then perform all administrative functions.
$ su - root

The NVRAM chip stores user-definable system parameters, also referred to as NVRAM variables or EEPROM parameters. The parameters allow administrators to
control variables such as the default boot device and boot command. The NVRAM also contains writeable areas for user- controlled diagnostics, macros, and
device aliases. NVRAM is where the system identification information is stored, such as the host ID, Ethernet address, and time-of-day (TOD) clock.
Examples of NVRAM variables:
Variable Default Description boot-device disk or net
The device from which to start up.
diag-device net The diagnostic startup source device.
diag-file Empty string Arguments passed to the startup program in diagnostic mode.
diag-switch? false Whether to run in diagnostic mode

Explanation
Explanation/Reference:
Explanation:
No OpenBoot Environment on the Intel Platform. The Intel environment has no OpenBoot PROM or NVRAM. On Intel systems, before the kernel is started, the
system is controlled by the basic input/output system (BIOS), the firmware interface on a PC. Therefore, many features provided by OpenBoot are not available on
Intel systems.
Note: The Open Boot PROM (OBP) bootloader only exists within SPARC. Before Solaris 10 01/06, the bootloader for Solaris x86 was a Sun customized bootstrap
software. After Solaris 10 01/06, it uses GRUB, a well known bootloader that's commonly used in the Linux world.
With GRUB, it's much easier to make the system dual-boot Linux and Solaris. GRUB extends the capabilities of the bootloader that was not available previously
such as the ability to boot from a USB DVD drive. Those who have used Linux will be quite familiar with GRUB and its options.

Explanation/Reference:
Explanation:
On POSIX-compliant platforms, SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header
file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.
SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process, but unlike the SIGKILL signal, it can be
caught and interpreted (or ignored) by the process. Therefore, SIGTERM is akin to asking a process to terminate nicely, allowing cleanup and closure of files. For
this reason, on many Unix systems during shutdown, init issues SIGTERM to all processes that are not essential to powering off, waits a few seconds, and then
issues SIGKILL to forcibly terminate any such processes that remain.

The authorized_keys file contains the private keys of remote users authorized to access jack's account on solaris.
The known_hosts file contains the verified public keys of remote hosts known to be trusted.
Correct Answer: AE
Section: (none)
Explanation
Explanation/Reference:
Explanation:
A: You will see two files starting with id_rsa. id_rsa is the private key and id_rsa.pub is public key.
E: The .ssh/known_hosts file
In order to use public-key secure connection with other hosts (ssh, scp, sftp) there is a special directory, ~/.ssh/, where passphrases and public keys are stored.
Normally you wouldn't need to know the gory details, but from time to time a host will change its public key and then you have difficulty using ssh or scp with that
host, and have to edit a file named known_hosts. If you try to ssh to another computer, but get an error message that warns about a changed or incorrect public
key, then it is probably just a case of that host changing its public key. (It is possible, though usually not the case, that malicious hacking is involved.) Unless you
actually suspect hacker involvement, you can edit the file ~/.ssh/known_hosts using your usual text editor (vi, emacs, nedit, or pico) and delete any line with the
name of that host.
Then when you try to ssh that host again, it will be like the first time ever; ssh will ask you if you want to accept a new public key, you type the whole word yes, and
everything will proceed normally from there.
Here is what a typical ~/.ssh/known_hosts file might contain. Note that newton is represented on two different lines:

Real 111
Oracle 1z0-821 Exam
H. The IP address of the zone is 10.0.2.18.
Correct Answer: CEG
Section: (none)
Explanation
Explanation/Reference:
Explanation:
C: Immutable Zones provide read-only file system profiles for solaris non-global zones.
Note that ip-type: exclusive:
Starting with OpenSolaris build 37 and Oracle Solaris 10 8/07, a default zone can be configured as an "exclusive-IP zone" which gives it exclusive access to the NIC
(s) that the zone has been assigned. Applications in such a zone can communicate directly with the NIC(s) available to the zone.
Note on zones:
After installing Oracle Solaris on a system, but before creating any zones, all processes run in the global zone. After you create a zone, it has processes that are
associated with that zone and no other zone. Any process created by a process in a non-global zone is also associated with that non-global zone.
Any zone which is not the global zone is called a non-global zone. Most people call non-global zones simply "zones." Some people call them "local zones" but this is
discouraged.
http://www.gratisexam.com/
The default native zone file system model on Oracle Solaris 10 is called "sparse-root." This model emphasizes efficiency and security at the cost of some
configuration flexibility. Sparse-root zones optimize physical memory and disk space usage by sharing some directories, like /usr and /lib. Sparse-root zones have
their own private file areas for directories like /etc and /var. Whole-root zones increase configuration flexibility but increase resource usage. They do not use shared
file systems for /usr, /lib, and a few others.
There is no supported way to convert an existing sparse-root zone to a whole-root zone. Creating a new zone is required.

A.
B.
C.
D.
kill -9 15163
kill -1 15163
kill -15 15163
kill -2 15163
Correct Answer: A
Section: (none)
Explanation
Explanation/Reference:
Explanation:
Here we should use SIGTERM to terminate the process.
Note:
When no signal is included in the kill command-line syntax, the default signal that is used is 15 (SIGKILL). Using the 9 signal (SIGTERM) with the kill command
ensures that the process terminates promptly. However, the 9 signal should not be used to kill certain processes, such as a database process, or an LDAP server
process. The result is that data might be lost.
Tip - When using the kill command to stop a process, first try using the command by itself, without including a signal option. Wait a few minutes to see if the
process terminates before using the kill command with the -9 signal.

Syslog daemon also writes to this /var/adm/messages file.

This script runs as the roots cron job everyday, checks the /var/adm/messages file and copies/moves it to /var/adm/messages.0, 1, 2, 3, 4, 5, 6, 7. In other words, it
does the Log Rotation for the /var/adm/messages.
In an event the /var file system is running out of space, these files needs to checked and can be removed (not the actual /var/adm/messages itself) to free up space
on the file system. However, care has to be taken, if you decide to empty the /var/adm/messages itself for any reason. This process is called Truncation.

Explanation
Explanation/Reference:
Explanation:
How to Recreate a ZFS Root Pool and Restore Root Pool Snapshots In this scenario, assume the following conditions:
* ZFS root pool cannot be recovered
* ZFS root pool snapshots are stored on a remote system and are shared over NFS
* The system is booted from an equivalent Solaris release to the root pool version so that the Solaris release and the pool version match. Otherwise, you will need
to add the -o version=version-number property option and value when you recreate the root pool in step 4 below.
All steps below are performed on the local system.
1.
Boot from CD/DVD or the network.
On a SPARC based system, select one of the following boot methods:
ok boot net -s
ok boot cdrom -s
If you don't use -s option, you'll need to exit the installation program.
2.
Mount the remote snapshot dataset.
For example:
# mount -F nfs remote-system:/rpool/snaps /mnt
3.
Recreate the root pool.
For example:
# zpool create -f -o failmode=continue -R /a -m legacy -o cachefile=/etc/zfs/zpool.cache rpool c1t0d0s0
4.
Restore the root pool snapshots.
This step might take some time. For example:
http://www.gratisexam.com/
# cat /mnt/rpool.0311 | zfs receive -Fdu rpool
Real 120
Oracle 1z0-821 Exam
Using the -u option means that the restored archive is not mounted when the zfs receive operation completes.
5.
Set the bootfs property on the root pool BE.
For example:
# zpool set bootfs=rpool/ROOT/osolBE rpool
6.
Install the boot blocks on the new disk.
On a SPARC based system:
# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t0d0s0

Correct Answer: D
Section: (none)
Explanation
Explanation/Reference:
Explanation:
If you want to create a backup of an existing boot environment, for example, prior to modifying the original boot environment, you can use the beadm command to
create and mount a new boot environment that is a clone of your active boot environment. This clone is listed as an alternate boot environment in the GRUB menu
http://www.gratisexam.com/
for x86 systems or in the boot menu for SPARC systems.
When you clone a boot environment by using the beadm create command, all supported zones in that boot environment are copied into the new boot environment.
How to Create a Boot Environment
Real 122
Oracle 1z0-821 Exam
1. Become the root role.
2. Create the boot environment.
# beadm create BeName
BeName is a variable for the name of the new boot environment. This new boot environment is inactive.
3. (Optional) Use the beadm mount command to mount the new boot environment.
# beadm mount BeName mount-point
Note: If the directory for the mount point does not exist, the beadm utility creates the directory, then mounts the boot environment on that directory.
If the boot environment is already mounted, the beadm mount command fails and does not remount the boot environment at the newly specified location.
4. (Optional) Activate the boot environment.
# beadm activate BeName
BeName is a variable for the name of the boot environment to be activated.
On reboot, the newly active boot environment is displayed as the default selection in the x86 GRUB menu or the SPARC boot menu.

Correct Answer: A
Section: (none)
Explanation
http://www.gratisexam.com/
Explanation/Reference:
Explanation:
Part of the job of cleaning up heavily loaded file systems involves locating and removing files that have not been used recently. You can locate unused files by using
the ls or find commands.
Other ways to conserve disk space include emptying temporary directories such as the directories located in /var/tmp or /var/spool, and deleting core and crash
dump files.
Note: Core files are generated when a process or application terminates abnormally. Core files are managed with the coreadm command.
For example, you can use the coreadm command to configure a system so that all process core files are placed in a single system directory. This means it is easier
to track problems by examining the core files in a specific directory whenever a process or daemon terminates abnormally.

D. umask value of 0722 set in /etc/profile
E. umask value of 0722 set In /export/home/jack/.bashrc
Correct Answer: B
Section: (none)
Explanation
Explanation/Reference:
Explanation:
The user file-creation mode mask (umask) is use to determine the file permission for newly created files. It can be used to control the default file permission for new
files. It is a four-digit octal number.
You can setup umask in /etc/bashrc or /etc/profile file for all users. By default most Unix distro set it to 0022 (022) or 0002 (002).
1. The default umask 002 used for normal user. With this mask default directory permissions are 775 and default file permissions are 664.
2. The default umask for the root user is 022 result into default directory permissions are 755 and default file permissions are 644.
3. For directories, the base permissions are (rwxrwxrwx) 0777 and for files they are 0666 (rw-rw- rw).
In short,
1. A umask of 022 allows only you to write data, but anyone can read data.
2. A umask of 077 is good for a completely private system. No other user can read or write your data if umask is set to 077.
3. A umask of 002 is good when you share data with other users in the same group. Members of your group can create and modify data files; those outside your
group can read data file, but cannot modify it. Set your umask to 007 to completely exclude users who are not group members.

High Print a summary report detailing the highest usage of each resource and zone during any interval of the zonestat utility invocation.
Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as a
percentage of system resources and the zone's configured limits.
The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval.
The default output is a summary of cpu, physical, and virtual memory utilization. The -r option can be used to choose detailed output for specific resources.

You are configuring NFS on a server. Select the two statements that are true.
A.
B.
C.
D.
Resources listed in /etc/dfs/dfstab are automatically shared on boot up.
A directory cannot be shared if a subdirectory below it is already shared.
Renaming a share created with the zfs set share command is not supported.
NFS and SMB protocols cannot be used simultaneously to share the same directory.
Correct Answer: AC
Section: (none)
Explanation
Explanation/Reference:
Explanation:
A: ZFS can automatically share file systems by setting the sharenfs property. Using this property, you do not have to modify the /etc/dfs/dfstab file when a new file
system is shared. The sharenfs property is a comma-separated list of options to pass to the share command. The value on is an alias for the default share options,
which provides read/write permissions to anyone. The value off indicates that the file system is not managed by ZFS and can be shared through traditional means,
such as the /etc/dfs/dfstab file. All file systems whose sharenfs property is not off are shared during boot.

- check a global zone's configuration for physical to virtual migration into non-global zone
The zonep2vchk utility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone. The p2v
process involves archiving a global zone (source), and then installing a non-global zone (target) using that archive
Zonep2vchk serves two functions. First, it can be used to report issues on the source which might prevent a successful p2v migration. Second, it can output a
template zonecfg, which can be used to assist in configuring the non-global zone target.
Zonep2vchk can be executed on a Solaris 10 or later global zone. To execute on Solaris 10, copy the zonep2vchkutility to the Solaris 10 source global zone. When
run on Solaris 10, a target release of S11 can be specified, which will check for p2v into a Solaris 10 Branded zone.

Explanation:
ZFS Deduplication Property
Solaris Express Community Edition, build 129: In this Solaris release, you can use the deduplication property to remove redundant data from your ZFS file systems.
If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored and common
components are shared between files.
You can enable this property as follows:
# zfs set dedup=on tank/home

Explanation:
Searching for Packages
Use the pkg search command to search for packages whose data matches the specified pattern.
Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg
search command returns the names of packages that match the query.
pkg search
search [-HIaflpr] [-o attribute ...] [-s repo_uri] query Search for matches to the query, and display the results. Which tokens are indexed are action-dependent, but
may include content hashes and pathnames.
Note: pkg is the retrieval client for the image packaging system. With a valid configuration, pkg can be invoked to create locations for packages to be installed,
called 'images', and install packages into those images. Packages are published by publishers, who may make their packages available at one or more repositories.
pkg, then, retrieves packages from a publisher's repository and installs them into an image.

A.
B.
C.
D.
E.
If the AI client does not match any criteria to use a custom manifest or script, the default manifest is used.
If the AI client does not match any criteria to use a custom manifest or script, the automated installation aborts.
Any manifest or script in a service can be designated to be the default for that service.
Only the default.xml file is used as the default AT client manifest.
If a client system does not use any SC profile, then an interactive tool opens on that client at first boot after that client installation to complete the configuration of
that client.
F. If a client system does not use any SC profile, then the install server will use the default SC profile.
Correct Answer: ADE

Explanation
Explanation/Reference:
Explanation:
A: Each client uses one and only one AI manifest to complete its installation. The AI manifest is selected for a client according to the following algorithm:
* If no custom AI manifests are defined for this install service, the default AI manifest is used. The default AI manifest is not associated with any client criteria etc.
D: When you create a new install service,
install_service_image_path/auto_install/manifest/default.xml is the initial default AI manifest for that install service.
E: Each client can use any number of system configuration profiles. If a client system does not use any configuration profile, then an interactive tool opens on that
client at first boot after that client installation to complete the configuration of that client.

You upgraded your server to Oracle Solaris 11 and you imported zpool (pool1) that was created in Solaris 10. You need to create an encrypted ZFS file system in
pool1, but first you need to make sure that your server supports ZFS encryption.
Which four statements are true for support of ZFS encryption?
A. The encrypted file system must have been created in Oracle Solaris11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and
create a new encrypted ZFS file system into the encrypted ZFS file system.
B. If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30.
C. ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.
D. ZFS encryption requires that the ZFS Dataset Encryption package be installed.
E. If you plan to create an encrypted file system in an existing zpool, the pool must be upgraded to ZFS version 21, minimum.
F. Encryption is supported at the pool or dataset (file system) level.

Explanation:
shadowd is a daemon that provides background worker threads to migrate data for a shadow migration. A shadow migration gradually moves data from a source
file system into a new "shadow" file system. Users can access and change their data within the shadow file system while migration is occurring.
The shadowd service is managed by the service management facility, smf(5). Administrative actions on this service, such as enabling, disabling, or requesting
restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.
The svccfg(1M) command can be used to manage the following parameter related to shadowd:
config_params/shadow_threads
Note: Oracle Solaris 11: In this release, you can migrate data from an old file system to a new file system while simultaneously allowing access and modification of
the new file system during the migration process.
Setting the shadow property on a new ZFS file system triggers the migration of the older data. The shadow property can be set to migrate data from the local
system or a remote system with either of the following values:
