Question #:1
Which Time Machine feature allows developers to automate the data refresh for their clones?
A. Manual Backup
B. update
C. Log Catchup
D. Schedule
Answer: D
Explanation
According to the Nutanix Database Automation (NCP-DB) learning documents, the Schedule feature of the
Time Machine allows developers to automate the data refresh for their clones1. This feature eliminates the
time-consuming, complex process of database clone/refresh, allowing admins to create database clones
/refresh to any point in time in just a few minutes1. Please refer to the official Nutanix documentation and
training materials for more detailed information2.
Question #:2
An administrator is looking to provision a relational database management system (RDBMS) in an HA
instance. Which two database engines are supported with NDB? (Choose two.)
A. MongoDB
B. MariaDB
C. Oracle
D. PostgreSGL
Answer: C D
Explanation
Nutanix Database Service (NDB) supports high availability (HA) instances for certain relational database
management systems (RDBMS). Among the listed options, NDB natively supports Oracle and PostgreSQL
for HA configurations, enabling features like replication and failover. These databases are well-integrated
with NDB’s Time Machine and HA frameworks.
Option A (MongoDB) is incorrect because MongoDB is a NoSQL database, not an RDBMS, and is not
supported for HA instances in NDB.
Option B (MariaDB) is incorrect because, while MariaDB is an RDBMS, it is not currently supported
for HA instances in NDB v6.10.

Answer: A
Explanation
When completing the NDB (Nutanix Database Service) Wizard for initial setup or configuration, certain steps
are mandatory to ensure the environment is properly configured, while others are optional based on specific
needs. Network Segmentation is an optional step that allows for advanced network isolation and
configuration, but it is not required for basic NDB deployment. Mandatory steps include specifying the NDB
Cluster Name, selecting a Storage Container, and configuring Services (e.g., database services), as these are
essential for NDB to function and manage databases.
Option A (Network Segmentation) is correct as it is an optional feature for advanced networking, not
a required step in the wizard.
Option B (NDB Cluster Name) is incorrect because assigning a cluster name is a mandatory step to
identify the NDB instance.
Option C (Storage Container) is incorrect because selecting a storage container is required for data
storage and protection.
Option D (Services) is incorrect because configuring services (e.g., database engines) is a core
requirement for NDB operation.
Note: The question mentions "NDE Wizard," which is assumed to be a typo for "NDB Wizard" based on
context.

Explanation
The Nutanix Era Time Machine provides various capabilities depending on the Service Level Agreement
(SLA) selected during database registration1. For a database with a Bronze SLA, the Time Machine supports
both “Log Catch up” and "Snapshots"2. “Log Catch up” allows the Time Machine to keep up with the latest
changes in the database by capturing log data2. “Snapshots” are point-in-time copies of the database that can
be used for recovery or cloning2.

D. Install ASMLIB on the database server.
Answer: A
Explanation
In the context of Nutanix Database Automation (NCP-DB), when provisioning a new Oracle SIHA DB &
VM, if only ASMFD is available in the ASM Driver drop-down, it indicates that ASMLIB is not included in
the current software profile. To provision the requested SIHA DB and DB VM with ASMLIB, it’s essential to
update the software profile to include the ASMLIB driver. This action will enable ASMLIB as an option in
the ASM Driver drop-down during the provisioning workflow.

Question #:7
An administrator needs to create and refresh clones to a point in time.
NDB allows which two methods for satisfying this requirement? (Choose two.)
A. Full backups
B. Snapshots
C. VM snapshots
D. Transaction logs
Answer: B D
Explanation
NDB allows creating and refreshing clones to a point in time using two primary methods:
B. Snapshots: NDB uses storage snapshots (e.g., via Nutanix Volumes or AHV) to capture the database
state at a specific point. These snapshots can be used to create or refresh clones, providing a consistent
recovery point.
D. Transaction logs: Transaction logs (e.g., PostgreSQL WAL, SQL Server logs) enable point-in-time
recovery (PITR) by applying logs to a snapshot, allowing clones to be refreshed to a precise moment.

Other options are not supported for this purpose:
A. Full backups: Full backups are used for complete restores but are not optimized for frequent clone
refreshes.
C. VM snapshots: VM-level snapshots (e.g., AHV snapshots) are not managed by NDB for database
cloning, as they lack database consistency.
Thus, the verified answers are B and D, reflecting NDB’s clone refresh capabilities.

Question #:8
A clone needs to be created on an existing database server, but there are no Authorized database servers
defined to support the cloned database.
In which two ways can Database Server VMs be authorized during a Clone Create operation? (Choose two.)
A. Within Time Machine, use the Actions menu and Authorize Database Server VMs to identify which
database server VMs to authorize for clones.
B. Within the Database Server VM Summary window, update the database sever to be authorized for
supporting cloned databases.
C. During the Clone creation process, click the plus icon to authorize one or more database server VMs.
D. During the database server provisioning process, flag the database server to be authorized for
supporting cloned databases.
Answer: A C
Explanation
When creating a clone on an existing database server but no Authorized database servers are defined to
support the cloned database, the administrator must authorize the necessary Database Server VMs. Two valid
methods exist within NDB: (1) Using the Time Machine interface, the administrator can navigate to the
Actions menu and select "Authorize Database Server VMs" to designate specific VMs for clone support,
providing a proactive authorization step. (2) During the Clone creation process, the wizard includes an option
(e.g., a plus icon) to authorize one or more database server VMs on the fly, streamlining the process if
authorization is needed mid-operation.

Option A (Within Time Machine, use the Actions menu and Authorize Database Server VMs to
identify which database server VMs to authorize for clones) is correct as it is a dedicated
authorization method in Time Machine.
Option B (Within the Database Server VM Summary window, update the database server to be
authorized for supporting cloned databases) is incorrect because the Summary window is for
viewing, not authorizing, clone support.
Option C (During the Clone creation process, click the plus icon to authorize one or more
database server VMs) is correct as it allows real-time authorization during cloning.
Option D (During the database server provisioning process, flag the database server to be
authorized for supporting cloned databases) is incorrect because authorization is not typically set
during initial provisioning but rather during clone operations.
These methods ensure the clone can be created on authorized servers.

Question #:10
An Era-managed production MSSQL database crashed during a busy holiday weekend and the administrator
has to restore the database to
the most recent timestamp with an objective to reduce the restore time and minimize data loss.
What option should the administrator do to achieve this objective?
A. Perform Restore Source Database by selecting Restore time just before the database crash.
B. Perform Restore Source Database by selecting most recent and include Tail log Backup
C. Perform Restore Source Database by selecting the available snapshot.
D. Perform Restore Source Database by selecting the current time.
Answer: B
Explanation
Nutanix Era is a database management solution that automates and simplifies database administration tasks
such as provisioning, patching, cloning, and backup. In the event of a database crash, the most effective way
to minimize data loss and reduce restore time is to perform a restore of the source database by selecting the
most recent point in time and including the Tail log Backup12.
The Tail log Backup includes all the transactions that have occurred since the last transaction log backup,
which helps to minimize data loss. By selecting the most recent point in time for the restore, the administrator
ensures that the database is restored to the state it was in just before the crash, thereby reducing the amount of
data that needs to be reprocessed or reentered12. This approach aligns with the Nutanix Era’s capabilities and
best practices for database recovery12.
