To reset the NDB GUI password in Nutanix Database Service (NDB), an administrator must access the system through an SSH session and use the appropriate command-line interface (CLI) tools provided by NDB. The correct process involves entering the era-server CLI, which is the specific CLI environment for managing NDB-related configurations, including security settings like password resets. Once in the era-server CLI, the administrator executes the security password reset command to initiate the password reset process for the NDB GUI. This method ensures that the reset is performed within the NDB-managed environment securely and aligns with Nutanix's recommended administrative procedures.
* Option A is correct because it specifies the era-server CLI and the exact command security password reset, which are consistent with NDB's administrative tools for managing GUI access credentials.
* Option B (sudo passwd era) is incorrect because era is not a system user account in the context of NDB's Linux-based control plane; this command pertains to standard Linux user management, not NDB-specific GUI password resets.
* Option C (sudo passwd admin) is also incorrect as admin refers to a generic user that may not correspond to the NDB GUI account, and this approach bypasses NDB's internal security mechanisms.
* Option D is incorrect due to a typo (era CLI instead of era-server CLI), which renders it imprecise despite the intent being similar to Option A.
This process assumes the administrator has SSH access to the NDB control plane VM and the necessary privileges to execute these commands.
