• Question 75:

  You have established an MSDP peering between multicast domains for your AS and a neighboring AS. You are concerned about unnecessary flooding or looping of source active messages between MSDP peers. Which MSDP mechanism is used to prevent this problem?

  A. The receiving MSDP peer performs a multicast RPF check to ensure that the SA messages are forwarded away from only the originating multicast source.
  B. The receiving MSDP peer sends register-stop messages towards the originating RP that forwarded the SA messages.
  C. The receiving MSDP peer performs amulticast peer-RPF check to ensure that the SA messages are forwarded away from only the originating RP.
  D. The receiving MSDP peer sends prune messages to all upstream neighbors to avoid receiving additional SA messages.
  C. The receiving MSDP peer performs amulticast peer-RPF check to ensure that the SA messages are forwarded away from only the originating RP.

• Question 76:

  Which two statements are associated with any-source multicast? (Choose two.)

  A. Routes learn the source of the multicast traffic from the source address of the multicast traffic.
  B. Routes learn the source of the multicast traffic from the receives.
  C. Routes do not specify a specific source from which to receive traffic.
  D. Receives select a specific source from which to receive traffic
  A. Routes learn the source of the multicast traffic from the source address of the multicast traffic.
  C. Routes do not specify a specific source from which to receive traffic.

• Question 77:

  Click the Exhibit button Both autonomous systems shown in the exhibit use BGP with a full-mesh IPGP configuration within each autonomous system and EBGP between the two autonomous systems. A single route is generated on R1 and advertised into BGP. Which two statements are true in this scenario? (Choose two.)

  

  A. R4 will not automatically readvertise the route to R5.
  B. R5 will automatically readvertise the route to other routers in AS 65512.
  C. R5 will not automatically readvertise the route to other routers in AS 65512.
  D. R4 will automatically readvertise the route to R5.
  C. R5 will not automatically readvertise the route to other routers in AS 65512.
  D. R4 will automatically readvertise the route to R5.

• Question 78:

  

  You are using PIM-SM in your network and want to ensure that all available equal-cost paths are being used for multicast traffic. Referring to the exhibit, where must you configure the PIM join-load-balance parameter to achieve this goal?

  A. R2, R4, and R5
  B. R1.R2, R4, and R5
  C. R4
  D. R4 and R5
  D. R4 and R5

• Question 79:

  An L1 router has formed an adjacency with an L1-L2 router.

  Under which condition will the L1-L2 router set the attach bit in its Level 1 link-state PDUs?

  A. when the L1-L2 router forms an adjacency with another L1 router in the same area
  B. when the L1-L2 router forms an adjacency with an L2 router in the same area
  C. when the L1-L2 router forms an adjacency with an L2 router in a different area
  D. when the L1-L2 router forms an adjacency with an L1 router in a different area
  C. when the L1-L2 router forms an adjacency with an L2 router in a different area

• Question 80:

  -- Exhibit ?

  

  -- Exhibit -Click the Exhibit button.

  In the exhibit, R2 is receiving external routing information for the 192.168.16.0/24 prefix and is redistributing it into IS-IS. R1 has a policy that leaks the 192.168.16.0/24 route into Area 49.1111. R3 has a policy that leaks the 192.168.16.0/24

  route into Area 49.2222. However, the IS-IS version of the route does not appear in R2's routing table.

  Why does R3's route leaking policy appear not to be working?

  A. The Up/Down bit is set to down for the prefix.
  B. The external flag is set for the prefix.
  C. You can only leak routes from Level 2 to Level 1.
  D. R2 already has better routing information for the prefix.
  A. The Up/Down bit is set to down for the prefix.
