Which of the following is true regarding VLANs?
A
You must have at least two VLANs defined in every Cisco switched network.
B
All VLANs are configured at the fastest switch and, by default, propagate this information to all other switches.
C
You should not have more than 10 switches in the same VTP domain.
D
VTP is used to send VLAN information to switches in a configured VTP domain.
Correct Answer: VTP is used to send VLAN information to switches in a configured VTP domain.
Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunk Protocol (VTP) is used to propagate VLAN information across a trunked link.
