What is a common recovery method if a misconfiguration prevents access to the device?

• A. Perform a reset as a last resort
• B. Load a backup
• C. Use Safe Mode during config changes to revert
• D. Reboot the device

Answer: (C)

Safe Mode acts as a safety net when configuring devices. When Safe Mode is active, changes you make aren’t permanent until you choose to keep them. If something goes wrong and you lose access, exiting Safe Mode (or the device doing so if you can’t continue) automatically reverts those recent changes, returning you to a known-good configuration. This makes it the most practical way to recover from a misconfiguration that locks you out, because you can undo the risky edits without having to manually reset or reload anything.

Drastic resets wipe everything and start from scratch, which is why they’re a last resort. Loading a backup can work, but you need a stored backup and a way to apply it. A plain reboot won’t necessarily undo saved configuration changes, so it’s not as reliable for recovery when access is blocked by a misconfiguration.
