What must be configured on a Cisco switch in order to advertise VLAN information?

A.
VTP mode

B.
VTP password

C.
VTP revision number

D.
VTP pruning

E.
VTP domain name

Explanation:

If the switch being installed is the first switch in the network, the management domain will need to be created. However, if the network has other switches running VTP, then the new switch will join an existing management domain. Verify the name of the management domain. If the management domain has been secured, verify and configure the password for the domain.
To create a management domain or to add a switch to a management domain, use the vtp domain command in the global configuration mode or VLAN configuration mode.
Switch(config)#vtp domain name
Switch(vlan)#vtp domain
