A technician replaced a malfunctioning network switch with an identical new switch from the same vendor. The model and hardware version of the new switch matched the broken unit. The technician extracts the config files from the old unit and installs it on the new unit. After installation, the new switch boot up and shuts down itself.

Question 168 Explanation:

In my experience, you always take a risk when you migrate a firmware config files from one unit to another even when hardware versions match.

The backups are useful when you need to reload the firmware to the same hardware.
