Question # 71

Refer to the exhibit.

A network operator wants to expand the segment routing global block in upcoming

maintenance. The operator must ensure that the changes to the segment routing global block have no adverse impacts on the prefix-sid associated with the loopback0 interface used within the OSPF domain.

Which command can the operator use to enforce R2 to have a strict prefix-sid assignment to loopback0?

A.

Option A

B.

Option B

C.

Option C

D.

Option D

Question # 72

Which two statements about route reflectors are true? (Choose two.)

A.

Routes received from nonclient peers are reflected to route reflector clients as well as nonclient peers.

B.

Routes received from nonclient peers are reflected to route reflector cluster as well as OSPF peers.

C.

If a router received an iBGP route with the originator-ID attribute set to its own router ID, the route is discarded.

D.

Routes received from a route reflector client is reflected to other clients and nonclient peers.

E.

If a route reflector receives a route with a cluster-list attribute containing a different cluster ID, the route is discarded.

Question # 73

Refer to the exhibit MPLS traffic from the packet core that is connected to router RX (10 10 101) to the radio network that is connected to router RB (10 10 10 6) uses the longer route RB R2 RY RX RX and R2 are configured with a default value of LDP hello and hold intervals The team verified that OSPF neighborship in Area 0 is established between RX and R2 Which action must be taken to choose the shortest path and resolve the issue?

A)

B)

C)

D)

A.

Option A

B.

Option B

C.

Option C

D.

Option D

Question # 74

A network engineer is troubleshooting OSPF multiareA. Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?

A.

hierarchical CLI

B.

DR support for topology management

C.

routing process enabled by default on all interfaces

D.

show ip ospf topology command

Question # 75

Refer to the exhibit.

What is the relationship between Router 1 and Router 2?

A.

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.

B.

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

C.

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

D.

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.

Question # 76

Refer to the exhibit.

Routers R1 and R2 cannot form a neighbor relationship, but the network is otherwise

configured correctly and operating normally. Which two statements describe the problem? (Choose two.)

A.

The two routers are in the same area

B.

The two routers are in different subnets

C.

The two routers have password mismatch issues

D.

The two routers have the same network ID

E.

The two routers are in different areas

Question # 77

While configuring Cisco NSF awareness, a network engineer enters the bgp graceful-restart command after the BGP session is established in a router that runs IOS XE Software. Graceful restart capabilities are not exchanged. Which two actions should be taken ? (Choose two.)

A.

Reload the router

B.

Verity that BGP route dampening is configured

C.

Reduce BGP convergence time

D.

Issue the clear ip bgp * command

E.

Issue the show ip bgp neighbors command.

Question # 78

Refer to the exhibit. A network engineer must correct the security policy on the EDGE_R router, which is connected to two Tier 1 ISPs. After another engineer added ip as-path access-list 11 permit 11 to EDGE_R, some routes from AS 11 and AS 4832 started to appear in the routing information base (RIB). Traffic control via Community options is disabled on both ISPs. How should the network engineer update the router configuration on EDGE_R so that only routes for AS 11 are permitted?

A.

Configure ip as-path prefix-list 11 permit _11$.

B.

Configure ip as-path access-list 11 permit _11_.

C.

Configure ip as-path distribution-list 11 deny A[0-9]+S.

D.

Configure ip as-path access-list 11 deny 4832$.

Question # 79

Which feature provides service independence in service provider networks?

A.

binding SID that is used to stitch different domains

B.

prefix SID that contains router hops toward the destination

C.

adjacency SID that represents a path between the routers

D.

node SID that identifies the network device

Question # 80

Refer to the exhibit.

.

R1 is expected to receive routes originating from AS 65516 and from any ASs that are directly attached to it. However, R1 is receiving routes only from AS 65516. Which action corrects the configuration?

A.

Change the regular expression in the AS-path permit filter to .* .

B.

Change the regular expression in the AS-path permit filter to ^65516_[0-9]*$ .

C.

Add the regular expression ^$. in the AS-path filter to permit the traffic from R2.

D.

Change the regular expression in the AS-path permit filter to _65516_ .
