Scenario 2: VLANs, Trunking, and VTP

This scenario is designed to stir your thinking about VLAN and trunking connectivity. You also need to examine switch configurations and apply them to a network diagram. See the diagram shown in Figure 19-2 and answer the questions that follow. Portions of the configurations of the three Catalyst switches are shown above them.

Figure 19-2. Diagram for Scenario 2

1.	PC-1 and PC-2 both are configured with IP addresses on the same subnet. Notice that each PC connects to a different VLAN number. Given the switch configurations shown, can PC-1 ping PC-2?
2.	PC-2 and PC-3 are assigned to the same IP subnet (using subnet mask 255.0.0.0) and the same VLAN. Can PC-2 and PC-3 ping each other?
3.	Will the trunk link between Catalyst B and Catalyst C come up successfully?
4.	Suppose that the trunk between Catalyst B and Catalyst C is configured properly. Where will VLAN1 be pruned? Why?
5.	Suppose that Catalyst A is a VTP server, Catalyst C is a VTP client, and Catalyst B is configured for VTP transparent mode. All switches are in the Bermuda management domain. If VLAN 14 is created on Catalyst A, which switches also will create VLAN 14 using VTP?
6.	If VLAN 15 is created on Catalyst B, what other switches also will create VLAN 15 through VTP?
7.	If VLAN 16 is created on Catalyst C, what will happen?
