Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 Sample Questions (Q22-Q27):

NEW QUESTION # 22
Where should an administrator perform an upgrade within the Era management interface?

A. Administration > Maintenance
B. Profiles Software
C. Alerts
D. Operations > Current Recent

Answer: A

Explanation:
In the Nutanix Era management interface, an administrator should perform an upgrade under the Administration > Maintenance section1. As part of the upgrade process, the Era server is upgraded first, followed by all the Era cluster agents and database server agents in parallel1. The Dashboard displays the current version and an option to upgrade the Era server to a latest version when a new version is available for upgrade1. This ensures that the Nutanix Era environment is always up-to-date with the latest features and security updates1.

NEW QUESTION # 23
Which ports are used by the NDB database agent for API calls?

A. 443 and 8080
B. 443 and 9440
C. 3205 and 3260
D. 5985 and 9389

Answer: B

Explanation:
The NDB database agent is a service that runs on each database server VM and communicates with the NDB instance. It uses port 443 for HTTPS API calls and port 9440 for Nutanix cluster API calls. These ports are required to be open on the database server VMs for NDB to function properly. References: Nutanix Database Management & Automation (NDMA), page 9; Ports and Protocols Reference Chart | Nutanix Community, section "Nutanix Database Service (NDB)"

NEW QUESTION # 24
Which site needs to be reachable to ensure an NDB server can send periodic telemetry data to the central Nutanix repository over port 443?

A. download.nutanix.com
B. insights.nutanix.com
C. portal.nutanix.com
D. developers.nutanix.com

Answer: B

Explanation:
To ensure an NDB server can send periodic telemetry data to the central Nutanix repository, the server must be able to communicate with the Nutanix Insights platform over port 443 (HTTPS). The insights.nutanix.com site is the designated endpoint for telemetry data, which includes usage statistics, health metrics, and other operational data sent to Nutanix for support and analytics purposes. This connectivity is a standard requirement for NDB to comply with Nutanix's telemetry and support framework, and port 443 is used for secure transmission.
* Option A (download.nutanix.com) is incorrect because this site is used for downloading software updates, not telemetry data.
* Option B (developers.nutanix.com) is incorrect as it is a resource for developers, not a telemetry endpoint.
* Option C (portal.nutanix.com) is incorrect because this is the Nutanix customer portal for account management, not telemetry submission.
* Option D (insights.nutanix.com) is correct as it is the specific site for sending telemetry data.
The administrator should ensure network policies allow outbound traffic to this site on port 443.

NEW QUESTION # 25
A request is received to refresh a database clone from a new manual snapshot. When the administrator attempts to create the new snapshot from the Time Machine, it is in a Frozen state.
What causes a Time Machine to enter the Frozen state and what are the administrator's options to complete the request?

A. Cause: The Time Machine enters a Frozen state after too many snapshot or log catchup failures.Resolution: Remediate the snapshot or log catchup failures, this thaws the Time Machine, allowing normal operations to continue and the request can be completed.
B. Cause: The Time Machine enters a Frozen state when the database is de-registered without removing the Time Machine.
Resolution: To complete the request the database must be re-registered in NDB, this thaws the Time Machine and it resumes operation so the clone can be refreshed.
C. Cause: The Time Machine enters a Frozen state when the database is de-registered without removing the Time Machine.
Resolution: The Time Machine must be paused, then the database re-registered with a new Time Machine and a new clone created.
D. Cause: The Time Machine enters a Frozen state when the database is de-registered without removing the Time Machine.
Resolution: To complete the request the database must be re-registered in NDB, create a new Time Machine and create a new clone.

Answer: B

Explanation:
A Time Machine is a core construct of the copy data management service in NDB that captures and manages the data of a database to deliver a recovery point objective (RPO) SLA. A Time Machine can enter a Frozen state for various reasons, such as database de-registration, snapshot or log catchup failures, or manual intervention.When a Time Machine is in a Frozen state, it stops taking new snapshots and log backups, and cannot perform any clone, refresh, or restore operations. To resume the normal operation of a Time Machine, it must be thawed by resolving the root cause of the freeze. One of the common causes of a Time Machine freeze is when the database is de-registered from NDB without removing the Time Machine. This can happen when the administrator wants to move the database to a different NDB instance or cluster, or when the database is accidentally de-registered. In this case, the Time Machine becomes orphaned and frozen, and cannot be used for any operations. To complete the request to refresh a database clone from a new manual snapshot, the administrator must first re-register the database in NDB using the same database name and ID as before. This will automatically thaw the Time Machine and resume its operation. The administrator can then create a new manual snapshot from the Time Machine and use it to refresh the database clone. The other options are not correct, as they either require unnecessary steps or do not address the root cause of the freeze. References:
