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?
Implement Link and Node protection on routers R2 and R7.
Disable traffic engineering so that traffic prefers the IGP path
Enable MPLS TE fast reroute on router R1 and Link and Node protection on router R2.
Configure IBGP full mesh for faster convergence.
Refer to the exhibit.
An administrator is troubleshooting network issues on a customer’s network PE1 cannot form an LDP relationship with PE2 using LDP ID 192 168.1.1. Due to this connectivity issue, the customer’s routes behind both PE routers cannot be exchanged. Which action must the administrator take to correct the problem?
Configure PE2 to automatically select its own LDP router ID with 192.168.1.1.
Create a targeted LDP session on PE2 to override the missing routing table entry on PEL
Configure PE1 with a static route to 192 168.1.1.
Enable LDP session protection on the link that P1 uses as the next hop to PE2.
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?
Enable OSPF peering and configure route redistribution between routers R4 and R1.
Enable route filtering between routers R1 and R3.
Enable MP-BGP peering on routers R1. R3, R4, and R5.
Enable OSPF on the Area-0 routers and configure MP-BGP between routers R1 and R3.
Refer to the exhibit.

120
230
110
10
Refer to the exhibit

VPN users that are connected to PE routers are facing network issues. Traffic that originates from CE1 drops before reaching CE2. An engineer finds no outgoing traffic statistics on PE1 and PE2 routers toward CE devices and finds that the PE1 router is running the older software image. Which action must be implemented to resolve the issues?
Enable LDP protocol on PE1 and PE2 routers.
Advertise P1 router loopback on PE1 in OSPF.
Enable CEF-based forwarding on PE1 router.
Advertise PE2 router loopback on PE1 in OSPF.
What are the two characteristics of route reflectors? (Choose two.)
If a router received an iBGP route with the originator-ID attribute set to its owm router ID, the route is discarded.
Routes received from nonclient peers are reflected to route reflector clients as well as nonclient peers.
Routes received from nonclient peers are reflected to route renector cluster as well as OSPF peers.
If a route reflector receives a route with a cluster-list attribute containing a different cluster ID, the route is discarded.
Routes received from a route reflector Client are reflected to other clients and nonclient peers.
Refer to the exhibit.
Refer to the exhibit After recent configuration changes to a customer's network, a network engineer notices that R2 cannot communicate with R3 Both FastEthemet interfaces on R2 and R3 are up and configured with the correct IP addresses MD5 password configured en 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?
Configure a loopback interface on R2 and assign it to area 0.
Define area 2 as a NSSA on R2 and R3
Configure virtual links between RI and R3.
Configure interface F0/0 on RI and R2 to be in area O.
Refer to the exhibit.
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?
Advertise the application server subnet in the router D IS-IS database
Advertise a static default route to the router B IS-IS database.

Multicast traffic destined from T1 and T2 routers to RP routers works well. A network engineer observes problems with multicast traffic flows between Site-A and Site-B. Site-A users fail to receive multicast stream on Site-B via RPTY site, while Site-B users fail to receive multicast stream on Site-Avia RPTZ site. Which action must be implemented to resolve the issues?
Establish MDSP peering with interface IP subnet.
Configure Site-A and Site-B in 10.80.14804
Allow the OSPF and MSDP packets on the firewall.
Configure direct OSPF peering between Site-A and Ste-B
