step can be done to troubleshoot the issue?

Options :

A : Switch the IGPs running in the core from IS-IS to OSPF to support a Cisco MPLS TE tunnel from PE1 to PE2.

B : Configure BGP between CE and PE routers.

C : Confirm that IS-IS is running with metric-style narrow.

D : Verify the MPLS LSPs

Answer: D

OSPF and EIGRP have been mutually redistributed on R1. but the team cannot view the routes on R3. Which action must the team take to resolve the issue?

Options :

A : Create a virtual link between R1 and R2.

B : Configure the routers in Area 2 to be in Area 0.

C : Disable stub routing in Area 1.

D : Redistribute connected routes on R3.

Answer: C

Question 5

Refer to the exhibit.

A network engineer configured routers R1 and R5 to run in IS-IS Level 1 mode and router R6 to run in IS-IS Level 2 mode. All other routers are running as Level 1 / Level 2 routers. An engineer expects traffic from R1 to R6 to pass via R2, but IS-IS routing has calculated the best path via R4. Which action corrects the problem?

Options :

A : Configure all routers as Level 1 routers.

B :

Remove the link metric for the link from router R1 to router R2.
