The switch can be rebooted from the working directory by using the ______ command.

• A. reload
• B. reload from working
• C. reboot working
• D. reload working

Answer: (D)

In many switches, there are two configuration sets: the startup configuration, which is used when the device boots, and the running (or working) configuration, which is active while the device is online. To reboot the switch using whatever is currently loaded in memory (the working configuration), you use the command that specifies the source as the working config. reload working tells the device to reboot and bring itself up using the in-memory (working) configuration rather than the startup one.

That’s why this is the best choice: it directly indicates rebooting from the currently active configuration. The other options don’t specify using the in-memory configuration, and some aren’t valid syntax for this CLI. If you want changes to survive after reboot, you’d typically save or copy the running configuration to startup first.
