Q25. To reduce the amount of signaling between switches which of the following timers must be modified? 

A. Configure the local age timer to be larger than the remote age timer 

B. Both timers should be the same to avoid unnecessary timeouts 

C. Configure the remote age timer to be larger than the local age timer 

D. The timers have no impact on the amount of signaling between switches 

Answer: D 

57. Study the diagram above. What consideration should be given to SDP 300? 

B. The SDP should be configured to use LDP encapsulation 

C. The SDP should be configured to use RSVP encapsulation with fast reroute 

D. The SDP should have signaling disabled 

Answer: C 


Q26. Based on the following output what will the vc-id be of any mesh-sdp bound to this service? 

A. 9000 

B. 1514 

C. 1000 

D. 0

Q27. Assume RSTP is being used within the Management VPLS. How can load balancing across the redundant SAPs be achieved? 

A. Two management VPLS instances must be created 

B. This is not possible when using RSTP within the management VPLS instance 

C. Create multiple managed-vlan-lists within the Management VPLS. Different SAPs will be blocked depending on the spanning tree parameters within the managed-vlan-list 

D. Spanning tree must be enabled in the user VPLS in order to provide load balancing 

Answer: A 


Q28. The FIB has learned 2 MAC addresses. The first from a device accessible via a locally defined SAP, the second from a device accessible via locally defined SDP.

A. MAC learned via SAP 

B. MAC learned via SDP 

C. There is not enough information to determine 

D. Both will timeout at the same time 

Answer: A
