Which statement about enabling segment routing for IGPs is true?

• A. Segment routing must first be enabled under then routing process and then globally
• B. Segment routing must first be enabled globally and then under the routing process
• C. Segment routing can be enabled only under the routing process
• D. Segment routing can be enabled only globally

Which task is performed when troubleshooting LDP?

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

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?

• A. Option A
• B. Option B
• C. Option C
• D. Option 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?

• A. TenGigE0/1 interface provides the alternate path
• B. A backup path must be statically installed
• C. TenGigE0/2 interface provides the alternate path
• D. A primary path must be manually installed

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?

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

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?

• A. It must be configured for graceful restart
• B. It must be configured with a route reflector
• C. It must be configured with send labels
• D. It must be configured with PIC edge

What can be used to determine a path from the head-end to a tail-end router when implementing
SR-TE with a head-end, with little information on the network topology?

• A. traffic controller
• B. path computation engine
• C. tail-end router
• D. SNMP server

Refer to the exhibit.

R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3
is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result
between
BGP peers R1, R2 and R1, R3 is true?

• A. The BGP session does not come up between R1 and R2 and between R1 and R3.
• B. The BGP session comes up between R1 and R2 and between R1 and R3.
• C. The BGP session comes up between R1 and R3, but not between R1 and R2.
• D. The BGP session comes up between R1 and R2, but not between R1 and R3.

Refer to the exhibit.

Router 1 has established an SR-TE tunnel with router 2. Which statement describes this
configuration?

• A. Router 1 has a list of labels used to explicitly lay out a path to router 2.
• B. Router 1 and router 2 have a bidirectional tunnel set up with dynamic path selection.
• C. Router 1 is the head-end tunnel and has dynamically chosen a path to router 2.
• D. Router 2 is the head-end tunnel and has explicitly set a path to router 1.
