One solved question, so you can see how these are marked

After assigning an IP address to a router interface with ip address 172.16.255.254 255.255.0.0, the interface still shows as administratively down. What additional command is needed to bring it up?

no shutdown

Administratively down means the interface is disabled in configuration. The no shutdown command removes that administrative shutdown; the interface will reach an up state only if the physical and data-link conditions are also satisfied.

Every question in the set below is marked like this. The answers stay hidden until you pick one.
