Refer to the exhibit. A network engineer is investigating a report of packet drops in an application running on a server connected to PE2 The engineer determined that:

    The OSPF adjacency in area 0 is up. and it is learning the loopback addresses of all routers in area 0.

    Traffic from users connected to PE1 to the application is also passing normally.

    Packets from PE2 back to PE1 are being dropped

Which action resolves the issue?

A.

Option A

B.

Option B

C.

Option C

D.

Option D

Refer to the exhibit. Network connectivity between bank A and bank B has been lost Users at bank A and bank B are able to successfully reach their directly connected PE routers. All routers in OSPF area 0 are correctly advertising and learning routing updates. Which action resolves the issue?

A.

Enable next-hop-self under the iBGP peering configuration on routers PEI and PE2

B.

Configure the P routers to redtstnbute BGP routes within OSPF area 0.

C.

Configure router PI to advertise the IP prefix of PEI.

D.

Configure MPLS with an end-to-end label-switched path on each router.

What is a feature of SRGB label values?

A.

They are used for adjacency segment identifiers.

B.

They allow IS-IS and OSPF to use overlapping ranges on a domain.

C.

They are locally significant.

D.

They are assigned to segment routing nodes and have global significance throughout the domain.

Refer to the exhibit. MPLS traffic from 192.168.4.0/24 to 192.168.5.0/24 is failing to pass over the link from R4 to R2. The engineer verified that:

    Cisco Express Forwarding Is enabled on all routers.

    All routers reach all networks via OSPF.

    MPLS traffic from 192.168.1.0/24 to 192.168.3.0/24 is passing normally over the link from R1 to R2.

Which action resolves the issue?

A.

On router R4, remove the mpls ip command on the s/O/O/2 interface.

B.

On router R2, configure the mpls ip command on the SIO/O/4 interface.

C.

On router R4, configure the mpls label protocol Idp command on all serial interfaces.

D.

On router R2, configure the mpls label protocol Idp command on the interface.

Refer to the exhibit.

A network operator must stop 10.33.33.33/32 from being redistributed into Level 1 router

XR1. Which configuration meets this need?

A.

Option A

B.

Option B

C.

Option C

D.

Option D

After changing the IP address on an IOS XR router, an engineer cannot ping the new address Which step did the engineer forget to complete?

A.

commit the configuration

B.

roll back the configuration

C.

save the running configuration

D.

merge the configuration

A network operator working for a telecommunication company with an employee id: 4074:92:707 is planning to implement the Nonstop Forwarding (NSR) feature on the customer’s core network. After getting the configuration ready for NSR. on which router should the operator implement NSR changes?

A.

on the CE router

B.

on the ASBR router

C.

on the ABR router

D.

on the PE router

Refer to the exhibit.

OSPF is an interior routing protocol on the network. R2 Is In the backbone area, and R4 is In a totally NSSA area. R5 announces only the 0.0.0.0/0 route to R4 via BGP. R4 is configured with redistribute bgp 736 metric-type 2. After the most recent maintenance window. R2 no longer has the default route via R4. Which action must the network engineer take to correct the reachability problem?

A.

Configure area 2 nsta no-summary under the global router configuration on router R2.

B.

Configure default-information-originate under the OSPF configuration on router R4.

C.

Configure ip route 0.0.0.0 0.0.0.0 nullO under the global router configuration on router R4.

D.

Configure area 2 nssa translate type7 no-suppress-fa under the OSPF configuration on router R2.

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?

A.

Configure all routers as Level 1 routers.

B.

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

C.

Change the link metric for the link from router R1 to router R2 to 1.

D.

Configure all routers as Level 1 / Level 2 routers.

Refer to the exhibit.

Traffic flow from router R1 to router R6 is delay-sensitive It must consider potential link-failure and node-failure conditions Which configuration must an engineer apply to router R1 to route traffic to router R6 if router R2 fails?

A.

Option A

B.

Option B

C.

Option C

D.

Option D
