QUESTION 30
Refer to the exhibit.

A network operator is getting the route for 10.11.11 0/24 from two upstream providers on
#XR3. The network operator must configure #XR3 to force the 10.11.11.0/24 prefix to route via next hop of 10.0.0.9 as primary when available. Which of these can the operator use the routing policy language for, to enforce this traffic forwarding path?

QUESTION 31
Refer to the exhibit. Which statement about this configuration is true?

QUESTION 32
Refer to the exhibit.

A network operator is troubleshooting TE tunnels and discovers that the soft preemption is not working as desired. Where should the soft preemption be applied to solve the issue?

QUESTION 33
Refer to the exhibit. A network engineer applied configuration on R1 to summarize all ISIS routes, but R2 is still receiving specific routes from R1. The engineer has confirmed that both routers are configured with the correct summarization configuration, but R1 is not sending the correct summary routes. Which configuration must be applied to router R1 to summarize routes within Level 1?

QUESTION 34
Refer to the exhibit.

CE1 is the gateway router into the provider network via PE1. A network operator must inject a default route into OSPF area 0. All devices inside area 0 must be able to reach PE1. Which configuration achieves this goal?

QUESTION 35
Refer to the exhibit. After recent configuration changes to a customer’s network, a network engineer notices that R2 cannot communicate with R3. Both FastEthernet interfaces on R2 and R3 are up and configured with the correct IP addresses. MD5 password configured on 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?

QUESTION 36
Referring to the topology diagram show in the exhibit, which three statements are correct regarding the BGP routing updates? (Choose three.)

Tasks
R21 through R25 are routers that perform MPLS label-forwarding operations. Candidates are required to perform the below configuration and verification tasks as noted.
1. Configure R22 and R23 to discover each other as LDP-speaking routers on the connected link.
2. Ensure the logical interface is selected as the persistent identifier on both R22 and R23.
3. Modify R21 and R25 to enable the MPLS-TE tunnel to be signaled and up between them.
Initial configuration with IP addressing has been completed.
The candidate must not make any changes to the configurations except to fulfill the tasks listed above. Only use the provided logical interface for the applicable task.
*The candidates have console access to all the routers R21, R22, R23, R24 and R 25.

QUESTION 38

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?

QUESTION 39
Refer to the exhibit.

Which statement about this configuration is true?

QUESTION 40
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?

QUESTION 41
Refer to the exhibit.

Refer to the exhibit A network engineer installed a new router (router 3) at the regional hub running MPLS services for scalability Router 3 is connected to the 10.44 4.0,’24. 10.44 5.024. 10 44.6.0/24. and 10 44 7 0/24 subnets The new router has been configured for OSPF area 2. and it is advertising the four connected networks. The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders Which action resolves the issue?

QUESTION 42
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?

QUESTION 43
While configuring Cisco NSF awareness, a network engineer enters the bgp graceful-restart command after the BGP session is established in a router that runs IOS XE Software. Graceful restart capabilities are not exchanged. Which two actions should be taken? (Choose two.)

QUESTION 44
