Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 Sample Questions (Q77-Q82):

NEW QUESTION # 77
An administrator needs to replace the default Nutanix self-signed certificates in Era.
Which SSL Certificate file format is supported?

A. PKCS#7
B. Base-64 encoded X 509
C. PKCS#12
D. DER encoded binary X.509

Answer: B

Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, Nutanix Era supports x509 certificates in Base-64 encoded PEM format1. This format is used when an administrator needs to replace the default Nutanix self-signed certificates in Era1.

NEW QUESTION # 78
An administrator needs to add multiple databases to an existing PostgreSQL instance.
How should the administrator satisfy this requirement?

A. Modify parameter profile using the GUI.
B. Modify parameter profile using NDB CLI.
C. Modify parameter profile using post script.
D. Modify parameter profile using ncli.

Answer: A

Explanation:
To add multiple databases to an existing PostgreSQL instance managed by NDB, the administrator should use the NDB graphical user interface (GUI). The GUI provides a user-friendly way to modify the parameter profile associated with the PostgreSQL instance, allowing the addition of new databases by adjusting settings such as database names, sizes, or configurations. This process typically involves navigating to the "Databases" or "Instances" section, selecting the PostgreSQL instance, and editing the parameter profile to include additional databases.
Other options are less appropriate:
* A. Modify parameter profile using ncli: The ncli (Nutanix Command Line Interface) is used for cluster-level management in Prism, not for NDB database configuration.
* C. Modify parameter profile using post script: Post-scripts are used for custom actions post- provisioning, not for modifying parameter profiles to add databases.
* D. Modify parameter profile using NDB CLI: While NDB has a CLI, the GUI is the recommended and supported method for such configuration changes, offering a guided workflow and validation.
Thus, the verified answer is B, leveraging the NDB GUI for ease and compliance with best practices.

NEW QUESTION # 79
When the NDB upgrade includes updates to the out-of-the-box (OOB) software profiles, what happens to older OOB software profile versions when upgrading NDB?

A. If the software profiles are not in use, NDB deletes all versions of the profiles from the metadata and protection domains.
B. If the database VMs using the software profiles are using Time Machines and have had a successful snapshot in the last 24 hours before the patch.
C. If the database VM using the software profiles are shutdown, NDB deletes all versions of the profiles from the metadata and protection domains.
D. If the database VMs are not using the base version of the software profile NDB deletes all versions of the profiles from the metadata and protection domains.

Answer: A

Explanation:
When upgrading NDB and the upgrade includes updates to out-of-the-box (OOB) software profiles (e.g., predefined profiles for database software like PostgreSQL, SQL Server, etc.), NDB manages older versions of these profiles based on their usage. If the older OOB software profiles are not actively in use by any database VMs, NDB automatically deletes all versions of those profiles from its metadata and associated protection domains during the upgrade process. This cleanup mechanism helps maintain a lean and efficient system by removing obsolete profiles that are no longer relevant or required.
* Option A is incorrect because the condition about Time Machines and snapshots in the last 24 hours is not a documented criterion for profile deletion during an NDB upgrade.
* Option B is correct as it reflects NDB's behavior of removing unused OOB software profiles during upgrades to optimize resource usage and metadata.
* Option C is incorrect because shutting down database VMs does not trigger automatic deletion of software profiles; the key factor is whether the profiles are in use.
* Option D is incorrect because the concept of a "base version" is not relevant here; deletion depends solely on whether the profiles are unused, not on versioning specifics.
This behavior ensures that only active and necessary profiles persist post-upgrade, streamlining administration.
