QUESTION 33

Click the Exhibit button. CE1, CE2, and CE3 are part of a single VPLS VPN. R1, R2, and R3 are PEs in the provider network, and have just been powered on. The VPLS domain has converged, and frames have passed between all CEs in the last minute. An Ethernet frame has just arrived at R3 from CE3. It has a source MAC address of CE3 and a destination MAC address of CE1.What does R3 do with the Ethernet frame?

 

clip_image006

 

A.

Drops the packet as the destination MAC address is not for R3.

B.

Drops the packet as the destination MAC address is not in R3’s MAC table.

C.

Forwards the packet to R1 only.

D.

Forwards the packet to R1 and R2.

QUESTION 36

Click the Exhibit button. Traffic is flowing through the interfaces in the exhibit as follows:

 

On ge-0/0/2.0, IPv4 traffic has a throughput rate of 4 Mbps, and the burst size counter is at 200 KB.

 

On ge-0/0/2.0, IPv6 traffic has a throughput rate of 7 Mbps, and the burst size counter is at 550 KB.
