An Infoblox appliance has been used for an evaluation and returned with data still on...

Comprehensive and Detailed In-Depth Explanation:Factory resetting an appliance with an unknown password requires physical access and a specific recovery method. The options provided don’t fully align with NIOS documentation, suggesting a possible error. Let’s evaluate:

Standard Process:

Boot the appliance, interrupt the boot sequence (e.g., via serial console), access anEmergency Promptor BIOS-like interface, and issue a factory reset command (typically set factory via CLI after recovery login).

Default recovery credentials (e.g., "infoblox/infoblox") may apply if not changed, but an unknown password implies deeper reset.

Options:

A:No "reset" username exists; default is "admin," and no menu offers "Factory Reset." Incorrect.

B:F12 isn’t a documented NIOS boot key—CLI access doesn’t use function keys this way. Incorrect.

C:F7 for Safe Mode isn’t standard, but Safe Mode could allow CLI access to run set factory. Closest plausible option, though not exact. Potentially correct with adjustment.

D:"reset all licenses" only clears licenses, not a full reset, and Emergency Prompt commands are broader (e.g., set factory). Incorrect.

Likely Correct Process:Interrupt boot, access Emergency Prompt (serial console), use recovery credentials or set factory—not perfectly matched here.

Practical Example:In an INE lab, you’d simulate this by booting a test appliance, resetting it via CLI, and reconfiguring it for Grid joining, testing troubleshooting skills.
