Comprehensive and Detailed In-Depth Explanation:Clearing the NIOS database requires a precise CLI command:

System logs (e.g., syslog, infoblox.log).

Licenses (e.g., reporting, DNSSEC).

Network settings (IP, hostname). Correct.

A:“reset all” isn’t valid (see Q28). Incorrect.

C:“reset config” isn’t a command—closest is set factory, which wipes everything. Incorrect.

D:reset all licenses clears licenses only, not the database. Incorrect.

Practical Example:In an INE lab, you’d run reset database, verify logs persist via show log, and reconfigure, testing Grid recovery.References:Infoblox NIOS CLI Reference Guide – Reset Commands; INE Course Content: NIOS DDI Grid Troubleshooting.
