You need to reset the database on a Grid member and disconnect it from the...

Comprehensive and Detailed In-Depth Explanation:Resetting a Grid member’s database while retaining network settings requires a targeted CLI command:

Requirements:Clear DNS/DHCP/Grid data, disconnect from the Grid, keep IP/hostname for reconnection or standalone use.

Commands:

reset database:Wipes the NIOS database (zones, leases, Grid membership), leaving network settings (IP, gateway, etc.) intact. The member becomes standalone, requiring rejoining if needed.

set factory:Full reset to factory defaults, erasing everything (database, network, licenses).

Options:

A (reset all):Not a valid command (see Q28). Incorrect.

B (reset database):Meets all criteria—clears database, disconnects, preserves network. Correct.

C (reset member):Not a specific CLI command; vague term. Incorrect.

D:Misinterprets the question as a statement—it’s possible with B, but this isn’t a command. Incorrect.

Practical Example:In an INE lab, you’d run reset database on a test member, verify its IP persists via show network, and troubleshoot rejoining the Grid.References:Infoblox NIOS CLI Reference Guide – Reset Commands; INE Course Content: NIOS DDI Grid Troubleshooting.
