C. Bootstrap message
D. Embedded RP
Answer: B
Q23. What is the position of the router shown in the exhibit?

Q24. What are the benefits of anycast RP? (Choose three)
A. Provide RP redundancy in a PIM SM network
B. Avoid the issue of shared-tree traffic concentration on a single RP in the network
C. Used to support incongruent topologies
D. Provide more optimal routing of the Shared Path Tree by allowing redundant RPs to be located closer to receivers
E. Provide more optimal routing of the Source Path Tree by allowing the receiver to connect to the closest multicast source
Answer: ABD

C. In the redundant core
D. As close as possible to the receiver
E. The Rendezvous Point can be positioned at any router without impact
Answer: B
Q27. What issues have to be resolved to support the deployment of SSM? (Choose two)

Q28. Refer to the configuration exhibit.
Which of the following statements is true?
A. 2 static RP's cannot be configured on the same device
B. 10.10.10.24 will be RP for 230.1.1.1 and 10.10.10.66 will be RP for 234.1.1.1
C. 10.10.10.24 will be RP for 234.1.1.1 and 10.10.10.66 will be RP for 230.1.1.1

Answer: C
Q29. When forwarding a multicast frame, the normal behavior for a LAN switch without IGMP snooping enabled is to forward the frame based on the same rules as if it were:
A. A unicast frame with a known destination in the forwarding table
B. A unicast frame with an unknown destination in the forwarding table
C. A unicast frame with a known source in the forwarding table
D. A unicast frame with an unknown source in the forwarding table
Answer: B
Q30. Which statement best describes the impact of an RP failure in a PIM ASM network?
A. All the existing multicast traffic will be stopped immediately as PIM ASM network must have an RP in order to transmit all the multicast traffic
B. The multicast traffic will be impacted, but not immediately. Multicast routers will not discover the RP failure until the timer expires and the multicast traffic flow will be stopped.
C. No impact at all as RP is not required in a PIM ASM network
D. The traffic will not be impacted if the multicast traffic flows have already been established and the traffic flow does not involve the RP in the path
Answer: D
