1. A router has two serial interfaces and two FastEthernet interfaces. It needs to connect to a wide area link to the main office and to four VLANs in the local network. How can this be accomplished in the most efficient manner?
Connect a trunked uplink from the switch to a router FastEthernet interface and create logical subinterfaces for each VLAN.
Use a hub to connect the four VLANS with a FastEthernet interface on the router.
Two additional FastEthernet interfaces are required to interconnect the VLANs.
Use serial to FastEthernet transceivers to connect two of the VLANs to the router. Attach the other two VLANs directly to the available FastEthernet ports.
Add a second router to handle the inter-VLAN traffic.

The switches in the diagram are connected with trunks within the same VTP management domain. Each switch is labeled with its VTP mode. A new VLAN is added to Switch3. This VLAN does not show up on the other switches. What is the reason for this?
VLANs cannot be created on transparent mode switches.
Server mode switches neither listen to nor forward VTP messages from transparent mode switches.
VLANs created on transparent mode switches are not included in VTP advertisements.
There are no ports assigned to the new VLAN on the other switches.
Transparent mode switches do not forward VTP advertisements.
