  B. to define the RP for PIM sparse mode and the different leafs
  C. to support control traffic between different VRFs
  D. to handle high-bandwidth source streams
  C. to support control traffic between different VRFs

• Question 63:

  Refer to the exhibit.

  

  An engineer is troubleshooting connectivity issues on the MPLS core network. A customer connected through R4 cannot reach the OSPF domain on R5. While checking the routing table of R1, the engineer cannot see all the routes from R3 and R5. Which task must the engineer perform so that R4 is able to reach R5?

  A. Enable OSPF peering and configure route redistribution between routers R4 and R1.
  B. Enable route filtering between routers R1 and R3.
  C. Enable MP-BGP peering on routers R1, R3, R4, and R5.
  D. Enable OSPF on the Area-0 routers and configure MP-BGP between routers R1 and R3.
  A. Enable OSPF peering and configure route redistribution between routers R4 and R1.

• Question 64:

  Refer to the exhibit.

  

  A network engineer has divided AS into confederations. Due to repeated ASN, when the 10.0 0.0/8 prefix from R1 arrives to R2, BGP automatically rejects it. What should the engineer do to fix the problem so that BGP allows that prefix on R2?

  A. Configure the command as-override on R1.
  B. Configure the command allowas-in on R2.
  C. Configure the command allowas-in on all the PE routers.
  D. Configure the command as-override on R2.
  B. Configure the command allowas-in on R2.

• Question 65:

  Refer to the exhibit.

  

  Router 1 has attempted to establish a Cisco MPLS TE tunnel to router 2, but the tunnel has failed. Which statement about this configuration is true?

  A. Router 1 must define an explicit path to router 2
  B. Router 1 and router 2 must define the RSVP bandwidth reserved on the physical interfaces
  C. Router 2 must have a tunnel interface created with router 1 as the destination
  D. Router 1 must have Cisco MPLS TE enabled on interface gigabitethernet0/1
  D. Router 1 must have Cisco MPLS TE enabled on interface gigabitethernet0/1

• Question 66:

  Refer to the exhibit.

  

  A network engineer is enabling a segment routing solution with these requirements:

  1.

  A service provider is using the default and nondefault SID range for interface allocation.

  2.

  192.168.10.0/30 interface should add an index value of 20 SID from the default range.

  3.

  192.168.30.0/30 interface should use a nondefault range and index value of 50. Which configuration must be implemented to meet the requirements?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

• Question 67:

  Refer to the exhibit.

  

  Which configuration ensures that RR2 does not send the same updates to PE2 that RR1 learns via PE1?

  A. RR1 and RR2 should have different router IDs.
  B. RR1 and RR2 should have different originator IDs.
  C. RR1 and RR2 should have the same router IDs.
  D. RR1 and RR2 should have the same cluster IDs.
  D. RR1 and RR2 should have the same cluster IDs.

• Question 68:

  Refer to the exhibit

  

  After recent configuration changes to a customer's network, a network engineer notices that R2 cannot communicate with R3 Both FastEthemet interfaces on R2 and R3 are up and configured with the correct IP addresses MD5 password configured en R2 and R3 match with no issues.

  What is the minimum change the engineer must make to enable R2 and R3 to communicate and fix the problem?

  A. Configure a loopback interface on R2 and assign it to area 0.
  B. Define area 2 as a NSSA on R2 and R3
  C. Configure virtual links between RI and R3.
  D. Configure interface F0/0 on RI and R2 to be in area 0.
  A. Configure a loopback interface on R2 and assign it to area 0.

• Question 69:

  Refer to the exhibit.

  

  While configuring router 2 with all the default values, a network engineer cannot see any route received in router 1. How should the engineer solve the issue?
