Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 Sample Questions (Q240-Q245):

NEW QUESTION # 240
When trying to restore a database via Time Machine (TM), the option to restore data to a Point in Time is not available.
What should the administrator do to enable Point in Time Recovery?

A. Update the TM schedule to perform DB Log catch up.
B. Take a Manual snapshot and use it for DB recovery.
C. Use Brass SLA & update the Log catch up frequency.
D. Use an SLA that supports Continuous Log retention.

Answer: D

Explanation:
Point in Time Recovery (PITR) is a feature of NDB that allows restoring a database to any point in time within the retention period of the SLA. To enable PITR, the SLA must support Continuous Log retention, which means that NDB captures and stores the database logs continuously. This allows NDB to replay the logs from the last snapshot to the desired point in time during the restore process. The other options do not enable PITR, but rather affect the frequency and timing of the snapshots and log catch up operations.

NEW QUESTION # 241
An administrator needs to roll back an Oracle patch on a database server VM using NDB. What is required for this action to be successful?

A. The patch must have been applied on Grid home only using NDB.
B. The database must be in read-only mode.
C. The database must be shut down.
D. The patch must have been applied using NDB.

Answer: D

Explanation:
To roll back an Oracle patch on a database server VM using NDB, the patch must have been applied using NDB in the first place. This is because NDB maintains a patch inventory and history for each database server VM and database that it manages. NDB uses this information to determine which patches can be rolled back and how to revert the changes made by the patch. If the patch was applied outside of NDB, NDB would not have the patch information and would not be able to roll back the patch. Therefore, the patch must have been applied using NDB for the rollback action to be successful. The other options are not required for the rollback action. The database does not need to be shut down or in read-only mode, as NDB can perform the rollback operation online. The patch does not need to be applied on Grid home only, as NDB can roll back patches applied on both Grid home and Database home. References:

NEW QUESTION # 242
An administrator needs to deploy a cumulative update (CU) for SQL Server.
What steps would the administrator take to prepare this deployment with NDB?

A. Apply the patch to the profile VM, then create a new Software Profile version using the profile VM as the source.
B. Create a new Software Profile using the CU executable and publish that profile.
C. Create a new Software Profile version using the CU executable and publish that version.
D. Apply the patch to the profile VM, delete the existing Software Profile and create a new Software Profile using the profile VM as the source.

Answer: A

Explanation:
The correct answer is C because it follows the recommended procedure for applying a CU to a SQL Server Software Profile in NDB. By applying the patch to the profile VM, the administrator ensures that the CU is compatible with the existing Software Profile settings and configuration. By creating a new Software Profile version, the administrator preserves the previous version of the Software Profile for rollback purposes and allows the new version to be tested and published. Option A is incorrect because it deletes the existing Software Profile, which may cause data loss and prevent rollback. Option B is incorrect because it does not apply the patch to the profile VM, which may result in errors or inconsistencies in the Software Profile.
Option D is incorrect because it creates a new Software Profile instead of a new version, which may cause confusion and duplication.

NEW QUESTION # 243
While registering an Always on Availability Group database, an administrator selects the following option:
Multiple Databases as a Group with One Time Machine
Which statement is true regarding this chosen option?

A. PITR-based SLAs are not supported for database groups.
B. PITR-based SLAs are not supported for database groups containing mixed Recovery Model
C. PITR-based SLAs are supported for database groups containing mixed Recovery Model.
D. Point in Time Clones are not supported by Database Groups.

Answer: B

Explanation:
Nutanix Database Automation (NCP-DB) introduces the concept of MS SQL Server database groups, which allows multiple databases running in the same database instance to be grouped as one Time Machine entity1. This applies to both single DB Server VM setups, standalone databases, as well as to Availability Group databases1. However, it does not support Point In Time Recovery (PITR)-based Service Level Agreements (SLAs) for database groups containing mixed Recovery Models. This means that if the databases within the group have different recovery models, PITR-based SLAs cannot be applied to the group as a whole.

NEW QUESTION # 244
What is causing this issue?

A. TheVLANisDHCP
B. The VLAN is stretched
C. The VLAN is IPAM
D. The VLAN is static

Answer: B

Explanation:
The correct answer is C because a stretched VLAN is a VLAN that spans across multiple Nutanix clusters, which may cause network conflicts or latency issues when starting the database server. Option A is incorrect because a DHCP VLAN is a VLAN that uses dynamic IP address allocation, which does not affect the database server startup. Option B is incorrect because a static VLAN is a VLAN that uses fixed IP address allocation, which also does not affect the database server startup. Option D is incorrect because IPAM is not a type of VLAN, but a feature of NDB that allows managing IP addresses for database servers and databases.
