If a switch is running from the certified directory, can changes be saved?

• A. Cannot be saved
• B. Can be saved
• C. They are saved automatically
• D. They require reboot

Answer: (A)

Running from the certified directory means the system image is in a read-only, verified state. That location is protected to keep the firmware intact, so you can’t write persistent changes to disk from there. Any configuration changes you make would only exist in memory and would disappear on reboot. To persist changes, you would need to switch to a writable image or directory and save to the startup configuration in nonvolatile storage there. So, changes cannot be saved when the switch is operating from the certified directory.
