A network consultant is troubleshooting IS-IS instances to identify why a routing domains is having communication problems between the two instances. Which description of the possible cause of issues in the routing domain is true?

The same interface cannot be advertised in two different IS-IS instances
The IS-IS "ISP" and "ISP2" instances are unrelated and unable to intercommunicate
The configured IS-IS NSEL value is not allowing the routing systems to establish a neighborship
The interface mode ip router is-is command was not included in the script

Correct answer: A

Segment routing must first be enabled globally and then under the routing process
Segment routing can be enabled only under the routing process
Segment routing can be enabled only globally

Correct answer: B

Which task is performed when troubleshooting LDP?

Execute the ping utility to generate information about the MAC addresses used along the path
Verify that MPLS is disabled globally and enabled on the necessary interfaces in a per-interface basis
Execute the traceroute utility to generate information about the labels used along the path
Verify that Cisco Express Forwarding has been disabled on the network

Correct answer: C

Refer to the exhibit.

XR1 and XR2 are sending the prefix 10.11.11.0/24 to XR3. A configured policy on XR1 is incorrectly prepending AS path 11 11 12 12 onto this prefix. A network operator wants to add a policy onto XR3 that will not allow the falsely prepending prefix from being installed. Which policy configuration applied to the XR3 neighbor configuration for XR1 can accomplish this requirement without impact to other or future received routes?

Correct answer: D

Refer to the exhibit.

Router 1 is connected to router 2 on interface TenGigE0/1. Which interface provides the alternate path to 172.16.200.9/32 when the link between router 1 and router 2 goes down?

TenGigE0/1 interface provides the alternate path
A backup path must be statically installed
TenGigE0/2 interface provides the alternate path
A primary path must be manually installed

Correct answer: C

Refer to the exhibit.

A network operator wants to expand the segment routing global block in upcoming maintenance. The operator must ensure that the changes to the segment routing global block have no adverse impacts on the prefix-sid associated with the loopback0 interface used within the OSPF domain.

Which command can the operator use to enforce R2 to have a strict prefix-sid assignment to loopback0?

Correct answer: C

Refer to the exhibit.

Router 1 is a core ABR in a Cisco Unified MPLS environment. All of the router 1 BGP peers are established, but traffic between customers is failing. Which BGP configuration must be added to the configuration?

It must be configured for graceful restart
It must be configured with a route reflector
It must be configured with send labels
It must be configured with PIC edge
