From the output in the exhibit, would could be the issue?

Read the question, and then refer to the exhibit.

A customer added a new switch to their network. They connected it using interface Ten-GigabitEthernet 1/0/1. They are using VLAN 10 and 20 for the devices in their network.

The new switch was fully operational. Then, the customer experienced a power failure later that day and could not reach any device on the new switch after the power returned.

From the output in the exhibit, would could be the issue?
A . The interface loopback is not set.
B. The interface link-speed and duplex are unknown.
C. The interface is administratively down.
D. The interface is configured for a PVID of VLAN 1.
