Nutanix Updated NCP-DB Exam Questions and Answers by imaan

 Nutanix Database Service (NDB) supports automated minor version upgrades for PostgreSQL1. Before applying the patch, the administrator should create a new software profile2. This is because the software profile contains the database engine binaries and other software required to run the database engine2. Therefore, to apply a minor version upgrade, a new software profile with the updated binaries needs to be created2. Once the new software profile is created, it can be used to patch the PostgreSQL database2.

 The optimal path to restore the table back with minimum data loss is to use the point in time restore feature of NDB, which allows the administrator to restore the database to a specific point in time based on the available snapshots and logs1. By restoring using point in time till 10:42pm, the administrator can recover the table just before it was dropped by the user, and minimize the data loss to the least possible amount1. The other options are not optimal, as they either involve restoring an older snapshot, which may result in more data loss, or restoring a non-existent snapshot, which is not possible. References:

A "dark site" refers to an environment with no internet connectivity, requiring manual processes for software updates. For Nutanix Database Service (NDB) in such a setup, updates cannot be downloaded automatically from the internet. The correct procedure is to:

Download the upgrade bundle: Access the Nutanix Support Portal from a system with internet access and download the NDB upgrade bundle specific to the version (e.g., v6.10 or later).

Manually upload it to the NDB server: Transfer the bundle to the NDB server (e.g., via SCP or USB) and upload it through the NDB interface under the "Software Updates" or "Maintenance" section.

Other options are incorrect in a dark site context:

B: The "Administrator > Maintenance" section allows initiating updates, but it cannot download files without internet access.

C: Changing the network to access https://download.nutanix.com defeats the dark site’s isolation and is impractical.

D: Uploading to Prism Element > Images is for VM images or other Prism-specific content, not NDB software updates.

Thus, the verified answer is A, aligning with Nutanix’s documented process for dark site updates.

The minimum frequency configurable for the NDB Log Catch-up operation is 15 minutes. This setting determines how frequently the log catch-up process runs, which is crucial for maintaining data integrity and ensuring up-to-date database states.References: Nutanix Database Automation documentation, focusing on log management and catch-up operation settings.
