NCP-DB Exam Dumps : Nutanix Certified Professional - Database Automation (NCP-DB v6.10)

 In Nutanix Database Automation (NCP-DB), the Database Parameters profile is used to manage database-specific settings, including the maximum number of database connections. This profile would be the appropriate choice when an administrator needs to change these settings during the cloning workflow1.

To change the NDB GUI password via the CLI, the administrator should use the command era-server > security password reset. This command interacts with the NDB server (referred to as era-server in the CLI context) to reset the password for the GUI admin user. The process typically prompts for the new password and confirmation, ensuring secure password management. This is the supported method for CLI-based password changes in NDB.

Other options are incorrect:

A. sudo passwd era: The passwd command is for Linux user accounts, not NDB-specific GUI credentials.

B. sudo user name admin password: This is not a valid command syntax for NDB CLI.

C. era-server > username admin password: This lacks the correct subcommand (security password reset) and syntax.

Thus, the verified answer is D, aligning with NDB’s CLI security management.

When using the "Patch OS now" feature in NDB to apply updates to a Red Hat-based operating system, the administrator can limit updates to security patches only by leveraging the Advanced Options. Under the "Custom commands" section of the operating system patching command window, entering yum update --security instructs the package manager to install only security-related updates. This ensures the system remains secure without applying all available updates, which could introduce instability.

Other options are incorrect or incomplete:

A. Point the database VM to a custom patch repository and enter yum update --security command: This requires manual intervention outside NDB’s patching framework.

B. Check Advanced Options and under Pre-post commands, enter yum update security in the pre-operating system patching command window: Pre-post commands are for pre/post actions, not the main patching process, and the syntax lacks the --security flag.

C. Point the database VM to a custom patch repository before using the Patch OS now feature: This sets up a repository but doesn’t specify security-only updates within NDB’s interface.

Thus, the verified answer is D, aligning with NDB’s patching customization.
