  D. Configure CEF before implementing BFD.
  B. Configure BFD between each adjacent router.

• Question 263:

  Refer to the exhibit.

  

  R1 is sending data traffic to R6 using the same SRGB range as the other routers in the topology, but it is also using a non-default SRLB range. Which two configuration tasks must the engineer perform to enable normal SRGB and SRLB operations on this network? (Choose two.)

  A. Configure router R2 with adjacency SID 4002 to enable it to reach R4.
  B. Configure an adjacency SID from SRLB range 1002 to 6005.
  C. Set the SRGB range to 1002 to 6005.
  D. Configure router R1 with adjacency SID 1003 to enable it to reach R2.
  E. Set the default SRGB range to 16000 to 23999.
  B. Configure an adjacency SID from SRLB range 1002 to 6005.
  E. Set the default SRGB range to 16000 to 23999.

• Question 264:

  Refer to the exhibit.

  

  Which three statements are correct regarding the Cisco IOS-XR configuration? (Choose three.)

  A. This router, acting as the RP mapping agent, will send RP announcement messages to the 224.0.1.40 group
  B. This router, acting as the RP mapping agent, will send RP discovery messages to the 224.0.1.39 group
  C. This router is the RP mapping agent only for the 224.11.11.11 and 224.99.99.99 multicast groups
  D. This router is a candidate PIM-SM RP for the 224.99.99.99 multicast group
  E. This router is a candidate PIM-BIDIR RP for the 224.11.11.11 multicast group
  F. IGMPv3 is enabled on all interfaces
  G. Other routers will recognize this router as the RP for all multicast groups with this router loopback 0 IP address
  D. This router is a candidate PIM-SM RP for the 224.99.99.99 multicast group
  E. This router is a candidate PIM-BIDIR RP for the 224.11.11.11 multicast group
  F. IGMPv3 is enabled on all interfaces

• Question 265:

  Refer to the exhibit.

  

  P1 and PE3 Cisco IOS XR routers are directly connected and have this configuration applied. The BGP session is not coming up. Assume that there is no IP reachability problem and both routers can open tcp port 179 to each other. Which two actions fix the issue? (Choose two.)

  A. Change MD5 to HMAC-SHA1-12
  B. Change MD5 to HMAC-ESP
  C. Change MD5 to SHA-1
  D. Change MD5 to HMAC-MD5
  E. Remove the send and accept lifetime under key 1
  A. Change MD5 to HMAC-SHA1-12
  D. Change MD5 to HMAC-MD5

• Question 266:

  What does conditional matching operate with RPL?

  A. The matching identifies a group of routes that are removed from the routing table when the administrator defined tags match.
  B. The matching identifies tags that are placed on routes from neighboring autonomous systems and drops the routes if they are the same.
  C. The matching identifies a set of criteria, and an action is taken based on whether the criteria are the same or different.
  D. The matching identifies interfaces that run the same routing protocol and manipulates data based on the routing rules.
  C. The matching identifies a set of criteria, and an action is taken based on whether the criteria are the same or different.

• Question 267:

  A network engineer must implement a Segment Routing policy rule that specifies that SIDs are bound manually. The policy will be used for traffic steering based on incoming labels, with Binding SIDs, Adjacency SIDs, and BGP Peering SIDs. All labels will be in the local segment, in the range 40,000?0,000. How must the engineer implement label allocation?

  A. Implement the standard default SRGB range in the SR global segment.
  B. Implement a non-default SRGB range in the SR local segment.
  C. Implement a non-default SRLB range in the SR global segment.
  D. Implement the default SRLB range in the SR local segment.
  B. Implement a non-default SRGB range in the SR local segment.

• Question 268:

  What is the function of BGP confederations?

  A. They assign an external BGP router to serve as the route reflector.
  B. They require routers to use private AS numbers.
  C. They eliminate the need for a fully-meshed internal BGP design.
  D. They enable a single device to distribute a common configuration to its peers.
  C. They eliminate the need for a fully-meshed internal BGP design.

• Question 269:

  Refer to the exhibit.
