A. Allow group VolumeAdmins to use volumes in tenancy
B. Allow group VolumeAdmins to copy volume' backups in tenancy
C. Allow group VolumeAdmins to manage volume-family In tenancy
D. Allow group VolumeAdmins to inspect volumes in tenancy
Answer: C
Explanation:
The backups feature of the Oracle Cloud Infrastructure Block Volume service lets you make a point-intime snapshot of the data on a block volume.These backups
can then be restored to new volumes either immediately after a backup or at a later time that you choose.
You can copy block volume backups between regions using the Console, command line interface (CLI), SDKs, or REST APIs.
To copy volume backups between regions, you must have permission to read and copy volume backups in the source region, and permission to create volume
backups in the destination region.
to do all things with block storage volumes, volume backups, and volume groups in all compartments with the exception of copying volume backups across
regions.
Allow group VolumeAdmins to manage volume-family in tenancy
The aggregate resource type volume-family does not include the VOLUME_BACKUP_COPY permission, so to enable copying volume backups across regions
you need to ensure that you include the third statement in that policy, which is:
Allow group VolumeAdmins to use volume-backups in tenancy where request.permission='VOLUME
_BACKUP_COPY'

For these applications running in OCI, they still need to interact with applications running on their onpremises data centers to Oracle Cloud Infrastructure (OCI). for these applications running in OCI. they still need to interact with applications running on their onpremises data centers. These applications require highly available, fault-tolerant network connections between on premises data centers and OCI.
Which option should you recommend to provide the highest level of redundancy?
A. Oracle cloud Infrastructure provides network redundancy by default so that no other operations are required
B. If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location
C. Set up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle Cloud Infrastructure.
D. Use FastConnect private peering only to ensure secure access from your data center to Oracle Cloud Infrastructure
E. Set up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It is cost effective
Answer: B
Explanation:
If your data centers span multiple geographical locations, we recommend using a broad CIDR (0.0.0.0/0) as a static route in addition to the CIDR of the specific
geographical location. This broad CIDR provides high availability and flexibility to your network design. For instance, the following diagram shows two networks in
separate geographical areas that each connect to Oracle Cloud Infrastructure. Each area has a single
on-premises router, so two IPSec VPN connections can be created. Note that each IPSec VPN connection has two static routes: one for the CIDR of the particular
geographical area, and a broad 0.0.0.0/0 static route.

Autonomous Database is an Oracle Managed and Secure environment. A physical database can’t simply be migrated to autonomous because:
- Database must be converted to PDB, upgraded to 19c, and encrypted
- Any changes to Oracle shipped privileges, stored procedures or views must be removed
- All legacy structures and unsupported features must be removed (e.g. legacy LOBs) GoldenGate replication can be used to keep database online during
migration

NEW QUESTION 82
You are part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a
VCN is not correct and want to delete the subnet. While deleting you are getting an error indicating that there are still resources that you must delete first. The error
includes the OCID of the VNIC that is in the subnet.
Which of the following action you will take to troubleshoot this issue?
A. Use OCI CLI to call "GetVnic" operation to find out the parent resource of the VNIC
B. Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC
C. Use OCI CLI to delete the VNIC first and then delete the subnet
D. Use OCI CLI to delete the subnet using --force option
Answer: A
Explanation:
VCN, it must first be empty and have no related resources or attached gateways To delete a VCN's subnets, they must first be empty.
Note: When you create one of the preceding resources, you specify a VCN and subnet for it. The relevant service creates at least one VNIC in the subnet and
attaches the VNIC to the resource. The service manages the VNICs on your behalf, so they are not readily apparent to you in the Console. The VNIC enables the
resource to communicate with other resources over the network. Although this documentation commonly talks about the resource itself being in the subnet, it's
actually the resource's attached VNIC.
If the subnet is not empty, you instead get an error indicating that there are still resources that you must delete first. The error includes the OCID of a VNIC that is
in the subnet (there could be more, but the error returns only a single VNIC's OCID).
You can use the Oracle Cloud Infrastructure command line interface (CLI) or another SDK or client to call the GetVnic operation with the VNIC OCID. The
response includes the VNIC's display name. Depending on the type of parent resource, the display name can indicate which parent resource the VNIC belongs to.
You can then delete that parent resource, or you can contact your administrator to determine who owns the resource. When the VNIC's parent resource is deleted,
the attached VNIC is also deleted from the subnet. If there are remaining VNICs in the subnet, repeat the process of determining and deleting each parent
resource until the subnet is empty. Then you can delete the subnet.
For example, if you're using the CLI, use this command to get information about the VNIC. oci network vnic get --vnic-id <VNIC_OCID

NEW QUESTION 99
An insurance company is storing critical financial data in the OCI block volume. This volume is currently encrypted using oracle managed keys. Due to regulatory
compliance, the customer wants to encrypt the data using the keys that they can control and not the keys which are controlled by Oracle.
What of the following series of tasks are required to encrypt the block volume using customer managed keys?
A. Create a vault, import your master encryption key into the vault, generate data encryption key, assign data encryption key to the block volume
B. Create a master encryption key, create a data encryption key, decrypt the block volume using existing oracle managed keys, encrypt the block volume using the
data encryption key
C. Create a vault, create a master encryption key in the vault, assign this master encryption key to the block volume
D. Create a master encryption key, create a new version of the encryption key, decrypt the block volume using existing oracle managed keys and encrypt using
new version of the encryption key
Answer: C
Explanation:
Oracle Cloud Infrastructure Vault lets you centrally manage the encryption keys that protect your data and the secret credentials that you use to securely access
resources. You can use the Vault service to create and manage the following resources:
Vaults
Keys
Secrets
Vaults securely store master encryption keys and secrets that you might otherwise store in configuration files or in code.
The Vault service lets you create vaults in your tenancy as containers for encryption keys and secrets. If needed, a virtual private vault provides you with a
dedicated partition in a hardware security module (HSM), offering a level of storage isolation for encryption keys that’s effectively equivalent to a virtual
independent HSM.

D. Configure your application to use synchronous master slave data replication between Availability Domains.
Answer: B
Explanation:
You can use the CLI, REST APIs, or the SDKs to automate, script, and manage volume backups and their lifecycle.
Planning Your Backup
The primary use of backups is to support business continuity, disaster recovery, and long-term archiving requirements. When determining a backup schedule, your
backup plan and goals should consider the following:
Frequency: How often you want to back up your data.
Recovery time: How long you can wait for a backup to be restored and accessible to the applications that use it. The time for a backup to complete varies on
several factors, but it will generally take a few minutes or longer, depending on the size of the data being backed up and the amount of data that has
changed since your last backup.
Number of stored backups: How many backups you need to keep available and the deletion schedule for those you no longer need. You can only create one
backup at a time, so if a backup is underway, it will need to complete before you can create another one. For details about the number of backups you can store

Answer: B
Explanation:
Oracle Cloud Infrastructure offers two distinct storage tiers for you to store your unstructured data. Use the Object Storage Standard tier for data to which you need
fast, immediate, and frequent access. Use the Archive Storage service's Archive tier for data that you access infrequently, but which must be preserved for long
periods of time. Both storage tiers use the same manageable resources (for example, objects and buckets). The difference is that when you upload a file to
Archive Storage, the object is immediately archived. Before you can access an archived object, you must first restore the object to the Standard tier.
you can use Storage Gateway to move files to Oracle Cloud Infrastructure Archive Storage as a cost effective backup solution. You can move individual files and
compressed or uncompressed ZIP or TAR
archives. Storing secondary copies of data is an ideal use case for Storage Gateway.
