Refer to the exhibit:

A network administrator is unable to connect remotely to a device and initiates a console session. The administrator executes the show ip interface brief command. Why did the remote connection fail?

A.
The Gigabit Ethernet interfaces are not up

B.
The switch does not have a management IP address assigned.

C.
The switch needs to have a clock rate entered on one of its interfaces.

D.
VLAN1 is shut down.

Explanation:
The virtual LAN Interface can be enabled or disabled with shutdown/no shutdown command. If you interface is down, it will display administratively down status. You can bring up an interface having administratively down interface using no shutdown command. Since the only IP configured on the switch belongs to VLAN 1, it needs to be enabled for you to remotely access the device.
