A. Router G-E-C 

B. Router F-D-E-G 

C. Router F-D-E-C 

D. Router C-A 

E. Router F-D-B-A

G. No Shared Path Tree will have been created 

Answer: AC 


Q43. Refer to the following exhibit. 

Assume all links have an equal metric in the IGP. Receiver 2 has joined the multicast group and the source is sending. As a result of Router F switching to the Source Path Tree, what message will be generated by Router D in the direction of Router E? 

A. PIM(*, G)Join 

B. IGMP(*, G)Join 

C. PIM Hello 

D. PIM (S, G)RP-bit prune 

E. PIM (*, G)RP-bit prune 

Answer: D 


Q44. Select the statements that relate to the Shared Path Tree. (Choose three) 

A. The RP is the root of the tree 

B. The multicast source is the root of the tree 

C. It is represented by (*, G) entries 

D. It is represented by (S. G) entries 

E. The path between receiver and source is always the shortest path 

F. It is always created as a result of switchover 

G. It is the initial forwarding path created 

Answer: ACG 


Q45. Refer to the exhibit. 

The switch is not igmp-snooping/proxy capable. What will happen if host 2 issues an IGMP report to join a group? 

A. Both Router A and Router B will get this IGMP report and Router B will propagate a PIM join towards the core network 

B. Both Router A and Router B will get this IGMP report and both of them will propagate a PIM join towards the core network 

C. Only Router A will get this IGMP report and Router A will propagate a PIM join towards the core network 

D. Only Router A will get this IGMP report and as Router A is not PIM DR, so no further action 

Answer: A 


Q46. If the access network supports IGMP version 2 only, what additional configuration is required to enable the SSM model?

D. 27 

E. 28 

Answer: C 


Q48. An IGMP version 3 receiver signals EXCLUDE mode with an empty EXCLUDE list. What does this indicate? 

A. This is the initial join message and exclusions of sources will follow 

B. It is willing to receive traffic from any source 

C. This is the initial join message and a selection of source will follow 

D. This is the way it indicates it is leaving the group 

Answer: B
