Which action resolves this problem?

Refer to the exhibit.

The users in an engineering department that connect to the same access switch cannot access the network. The network engineer found that the engineering VLAN is missing from the database.

Which action resolves this problem?
A . Disable VTP pruning and disable 802.1q.
B . Update the VTP revision number.
C . Change VTP mode to server and enable 802.1q.
D . Enable VTP pruning and disable 802.1q.

Answer: C

Explanation:

Only VTP servers can add new VLANs to the switched network, so to enable vlan 10 on this switch you will first need to change the VTP mode from client to server. Then, you will need to enable 802.1Q trunking to pass this new VLAN along to the other switches.
