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?

Options :

A : Implement Link and Node protection on routers R2 and R7.

B : Disable traffic engineering so that traffic prefers the IGP path

C : Enable MPLS TE fast reroute on router R1 and Link and Node protection on router R2.

D : Configure IBGP full mesh for faster convergence.

Answer: C

Question 4

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?

Options :

A : Configure PE2 to automatically select its own LDP router ID with 192.168.1.1.

B : Create a targeted LDP session on PE2 to override the missing routing table entry on PEL

C : Configure PE1 with a static route to 192 168.1.1.

D : Enable LDP session protection on the link that P1 uses as the next hop to PE2.

Answer: C

Question 5

Refer to the exhibit.

IS-IS is the routing protocol on the network. After the team noticed excessive CPU usage on all routers, particularly routers R2 and R6, they configured route summarization on all routers. However, a network engineer noticed that summary routes and more specific routes are present in the routing table on R1. Which action must the team take so that R1 receives only the summary routes?

Options :

A : Configure R2 and R4 to perform summarization for Level 1 routers.

B :

Configure R3 to perform summarization for Level 1 routers, and configure R6 to perform summarization for Level 2 routers.

C : Configure R3 and R5 to perform summarization for Level 1 and Level 2 routers.

D : Configure R6 only to perform summarization for all routers.

Answer: B
