Refer to the exhibit. A network associate has the task of planning a Frame Relay implementation
to replace the existing WAN infrastructure. The addresses for the North, East, and South branch
offices have been assigned as shown in the diagram. Which type of topology should be
implemented?
A.
full mesh
B.
hub and spoke
C.
ring
D.
bus
E.
extended star
Explanation:
In a Fully meshed environment, every router has a PVC defined to every other router and in a
Non-fully meshed environment (or Hub and Spoke) PVCs are only defined between routers that
need to communicate. In this example, a /30 IP subnet mask is used at each remote location.
This mask allows for only two hosts on the network, which will used for the local router’s frame
relay interface, and the hub router’s interface. In this example, all site to site (spoke) traffic will
need to traverse through the main (hub) location.
