問題3

Redundant spoke-SDPs are used between 2 Metro networks for redundancy. How can load balancing be achieved across the redundant spoke-SDPs?

A. A single management VPLS using 802.1D-2004 can be used to block different SDPs for different VPLS services

B. Two management VPLS using RSTP can be used to block different SDPs for different VPLS services.

C. A single management VPLS using RSTP can be used to block different SDPs for different VPLS services.

D. There is no way to have load balancing across redundant spoke-SDPs.

正確答案: B

問題4

Click on the exhibit below.

Management VPLS 100 has been created for redundant spoke-SDP connections. User VPLSs 10 and 20 are using the same spoke-SDPs that are being managed by VPLS 100. Unexpected behavior has been reported. Based on the following output, what is the most likely reason for the unexpected behavior?

A. VPLS 10 and VPLS 20 are not using the same spoke-sdps that the management VPLS is using.

B. VPLS 10 and VPLS 20 are not actually configured as a user VPLS.

C. VPLS 100 was not actually configured as a management VPLS.

D. Based on the output there is now way of telling if there is a problem with the configuration.

正確答案: C

問題6

Click on the exhibit below.

Assume a CE router is connected to the SAP of each PE. The arp cache of all CE routers is empty and the FDB for VPLS 300 is empty. The CE router connected to PE-A initiates a ping towards the CE router connected to PE-C. The ping is successful. Which of the following statements are true? (Choose 2)

A. The FDB on PE-B will contain an entry for all CE routers.

B. The FDB on PE-C will contain entries for the CE router connected to PE-A and the CE router connected to PE-C.

C. The FDB on PE-A will contain entries for all CE routers.

D. The FDB on PE-B will contain an entry for the CE router connected to PE-A.

正確答案: B,D

問題8

Which of the following statements regarding unicastand multicast frames is true for a traditional layer 2 switch? (Choose 2)

A. If the FDB is empty, unicast and multicast frames are treated equally.

B. Unicast frames only forward out ports that have a known receiver.

C. Multicast frames only forward out ports that have a known receiver.

D. If the FDB has an entry for the unicast frame, both unicastand multicast are treated equally.

正確答案: A,B
