An MPLS core network has connectivity issues R4 has failed. It impacts traffic loss between R1 and R8.
Customers report no access to their file servers, which delays their transformation work. Which quick action resolves the issue until R4 recovers?

정답: D
Refer to the exhibit.
All backbone interfaces on the network are in VRF_MPLS and ip rsvp signalling hello is preconfigured on all MPLS routers in the network. After router R2 is upgraded and its configuration restored from backup. LSP signaled via RSVP that the tunnel from R1 had been tom down The network engineer confirmed IP reachability line the backbone network Which action must the engineer take to fix the issue?

정답: D,E
Refer to the exhibit A network engineer configured the redistribute connected subnets route-map filtering command on R1 to redistribute connected interfaces to the OSPF process The engineer also wants to filter out IP address 10 0 1 0/24. but the prefix still appears in the routing tables of the other routers on the network.
Which action corrects the problem?
정답: B

Refer to the exhibit. Customers A and C are experiencing packet drops when connecting to the application server.
While troubleshooting the problem the network engineer confirms that the IS-lS Level- 1/2 adjacency is up between routers A B C. and D and both customers can communicate with the database server without packet loss.
Which action must the engineer take to resolve the issue?
정답: B
Refer to me exhibit.
A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routers coming from ASN 64502. but allow all the others.
For that purpose, the following AS Pam prefix 1st s being used:
What must be fixed to achieve this result?

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?

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?

BGP is running on the network, and CE1 currently prefers routes to the internet via PE 1 A network engineer must manipulate the BGP routes that CE1 receives from PE2 to be more desirable The engineer configured a route map using MED and applied it on CE1 outbound from PE2. However, after a BGP soft reset. PE1 is still preferred. Which action must the engineer take so that PE2 is chosen as the next hop?
