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?

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

Correct Answer: D

Refer to the exhibit. CE1 and CE2 cannot communicate through the service provider BGP peering is established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core. What step can be done to troubleshoot the issue?

1. A. Switch the IGPs running in the core from IS-IS to OSPF to support a Cisco MPLS TE tunnel from PE1 to PE2.
2. B. Configure BGP between CE and PE routers.
3. C. Confirm that IS-IS is running with metric-style narrow.
4. D. Verify the MPLS LSPs.

Correct Answer: C

Refer to the exhibit. An engineer has successfully fixed BGP peering issue. R1 has an established eBGP peering with R2 and R3. Which mechanism should the engineer apply in order to steer the traffic correctly?

1. A. The MED attribute can be applied on R2 to influence R1 to use it as the primary path.
2. B. The local preference attribute can be applied on R3 to influence AS 65513 to use AS 65515 as the secondary path.
3. C. The weight attribute can be applied on R2 to influence AS 65513 to use AS 65515 as the primary path.
4. D. The IGP metric can be manipulated on R1 to allow traffic to be load balanced between R2 and R3.

Correct Answer: D

Refer to the exhibit. How are packets directed through the data plane when SRv6 is implemented?

1. A. An ordered list of segments is encoded in a routing extension header
2. B. The MPLS data plane is used to push labels onto IGP routes
3. C. A stack of labels represents an ordered list of segments
4. D. The packet is encapsulated with a header and trailer encoding the ordered list of segments

Correct Answer: A
