In Cisco VTP, which mode does not participate in VLAN distribution but forwards advertisements?

• A. Transparent mode
• B. Server mode
• C. Client mode
• D. Hybrid mode

Answer: (A)

In VTP, how a switch handles VLAN information is determined by its mode. The switch that does not participate in creating or applying VLAN changes but still forwards VTP advertisements is the Transparent mode. It keeps its own locally configured VLANs and does not add or delete VLANs based on VTP updates, but it passes along any VTP advertisements it receives on trunk links to other switches. This lets VLAN changes traverse the network without this switch altering its own VLAN database. In contrast, a server can create and store VLANs and advertise them to others, while a client only accepts updates from servers to modify its VLAN database. Some IOS versions include a hybrid approach, which still involves participation in VLAN distribution in some capacity, so it isn’t just a pure forwarding role.
