Refer to the exhibit. An organization connects two locations, supporting two VLANs, through two

switches as shown. Inter-VLAN communication is not required. The network is working properly
and there is full connectivity. The organization needs to add additional VLANs, so it has been
decided to implement VTP. Both switches are configured as VTP servers in the same VTP
domain. VLANs added to Switch1 are not learned by Switch2. Based on this information and the
partial configurations in the exhibit, what is the problem?

A.
Switch2 should be configured as a VTP client.

B.
VTP is Cisco proprietary and requires a different trunking encapsulation.

C.
A router is required to route VTP advertisements between the switches.

D.
STP has blocked one of the links between the switches, limiting connectivity.

E.
The links between the switches are access links.

Explanation:
A trunk link is a special connection; the key difference between an ordinary connection (access
port) and a trunk port is that although an Access port is only in one VLAN at a time, a trunk port
has the job of carrying traffic for all VLANs from one switch to another. Any time you connect a
switch to another switch and want to make sure that all VLANs will be carried across the switches,
you want to make it a trunk.
To carry on the data frames for all VLANs, you need to create the Trunk link on switch port as well
as you need to select the encapsulation type.

In the above topology the switches are connected on access ports. Making them trunk ports
should solve this issue.
