Question 81

A CRS router that runs Cisco IOS XR has dual routing processors installed.
Which solution should be implemented to prevent OSPF adjacency flapping if the primary routing processor fails?

A.NSF

B.OSPF Fast Timers

C.router msdp

D.NSR

E.OSPF RE Sync

Question 82

Refer to the exhibit. Router 1 and Routed have shared routes in the OSPF database but the routes are missing from their routing tables. Checking me prefix-list configuration on both routers, the engineer confirmed all networks are allowed. What action should the engineer take to fa the problem?

A.Configure interface Senal1/0 on Router1 as a point-to-point interface

B.Switch the DR and BDR roles between the two routers

C.Configure the two routers with different hello and dead timer values

D.Configure the two routers with different process IDs

Question 83

Refer to the exhibit.

P1 and PE3 Cisco IOS XR routers are directly connected and have this configuration applied. The BGP session is not coming up. Assume that there is no IP reachability problem and both routers can open tcp port 179 to each other. Which two actions fix the issue? (Choose two.)

A.Change MD5 to HMAC-ESP

B.Change MD5 to HMAC-SHA1-12

C.Remove the send and accept lifetime under key 1

D.Change MD5 to SHA-1

E.Change MD5 to HMAC-MD5

Question 84

Refer to the exhibit. What is the relationship between Router 1 and Router 2?

A.Router 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1.

B.Router 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information.

C.Router 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers.

D.Router 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers.

Question 85

Refer to the exhibit.

Router 1 has established an SR-TE tunnel with router 2. Which statement describes this configuration?

A.Router 1 has a list of labels used to explicitly lay out a path to router 2.

B.Router 2 is the head-end tunnel and has explicitly set a path to router 1.

C.Router 1 and router 2 have a bidirectional tunnel set up with dynamic path selection.

D.Router 1 is the head-end tunnel and has dynamically chosen a path to router 2.
