D.Serial0/1.102

E.Serial0/1.103

F.Serial0/1.104

Refer to the exhibit. All routers have Protocol Independent Multicast (PIM) enabled interfaces. On the basis of the configuration provided on routers R1 and R2, which router will take on the func tion of rendezvous point (RP) for the multicast network？ （）

A. both routers R1 and R2

B. router R1

C. router R2

D. none of the routers since they are not configured with static RP

A. traffic - share balanced

B. distance

C. maximum- paths

D. default - network

E. variance

A. Any routes learned by R2 from the interface tied to the 172.16.0.0 network will not be advertised to neighbors on the 192.168.2.0 network.

B. Only routes learned by R2 from the interface tied to the 172.16.0.0 network will be advertised to neighbors on the 192.168.2.0 network.

C. Only the 172.16.0.0 network will be advertised to neighbors on the 192.168.2.0 network.

D. All networks, except the 172.16.0.0 network will be advertised to neighbors on the 192.168.2.0 network .

A.The last default - network statement will always be preferred.

B.A route to the 140.140.0.0 network does not exist in the routing table.

C.Default - network selection will always prefer the statement with the lowest IP address.

D.A router will load balance across multiple default - networks; repeatedly issuing the show ip route command would show the gateway of last resort changing between the two networks.

A.With a network wide mask of 255.255.255.128, each interface does not require an IP address.

B.With a network wide mask of 255.255.255.128, each interface does require an IP address on a unique IP subnet.

C.With a network wide mask of 255.255.255.0, must be a Layer 2 device for the PCs to communicate with each other.

D.With a network wide mask of 255.255.255.0, must be a Layer 3 device for the PCs to communicate with each other.

E.With a network wide mask of 255.255.254.0, each interface does not require an IP address.
