  A. 131065
  B. 131064
  C. 131067
  D. 131071

  How many interfaces have receivers joining group 239.1.1.1?

  A. 1
  B. 2

• Question 74:

  Which of the following is NOT a benefit of anycast RP?

  A. It provides RP redundancy in a PIM SM network.
  B. It provides load balancing between multiple RPs in the network,
  C. It supports a different multicast topology than the unicast topology.
  D. It supports more optimal routing of the Shared Path Tree by allowing redundant RPs to be located closer to receivers.
  C. It supports a different multicast topology than the unicast topology.

• Question 75:

  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
  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

• Question 76:

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

  A. It is willing to receive traffic from all sources
  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
  D. This is the way it indicates it is leaving the group

• Question 77:

  What is the default version of IGMP on the Alcatel-Lucent 7750 SR?

  A. Version 1
  B. Version 2
  C. Version 3
  D. There is no default setting, you must configure the version when you enable IGMP on 7750 SR
  C. Version 3

• Question 78:

  Which of the following commands will verify, either directly or indirectly, if PIM is configured on an interface on the Alcatel-Lucent 7750 SR? (Choose two)

  A. show router pim interface
  B. show router pim status detail
  C. show router pim status
  D. show router interface detail
  A. show router pim interface
  D. show router interface detail

• Question 79:

  Which of the following is NOT an advantage of using P2MP LSP as P-tunnels that instantiate PMSIs?

  A. P-tunnels can be protected with fast reroute for better resiliency.
  B. PIM is no longer required in the provider core.
  C. P2MP LSP tunnels forward multicast traffic only to the PEs with interested receivers.
  D. Traffic engineering of the P-tunnels is possible with P2MP LSPs.
  C. P2MP LSP tunnels forward multicast traffic only to the PEs with interested receivers.

• Question 80:

  The Draft-Rosen S-PMSI address range is configured for 32 group addresses. What happens if there are more than 32 customer multicast flows that exceed the threshold configured for the MVPN?

  A. Traffic for the 33rd multicast flow is dropped.
  B. Traffic for the 33rd multicast flow is transmitted on the I-PMSI.
  C. The source PE reassigns the S-PMSI with the smallest flow to the new multicast flow. Traffic for the smaller flow is transmitted on the I-PMSI.
  D. The source PE re-uses an S-PMSI that is currently in use for the 33rd flow. Traffic for both flows is sent on the same S-PMSI.
  D. The source PE re-uses an S-PMSI that is currently in use for the 33rd flow. Traffic for both flows is sent on the same S-PMSI.
