Question 1

Refer to the exhibit.

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

B : nfigure the P routers to redtstnbute BGP routes within OSPF area 0.

C : nfigure router PI to advertise the IP prefix of PEI.

D : nfigure MPLS with an end-to-end label-switched path on each router.

Answer: D

Question 2

The engineering team at ISP_1 must improve network stability time and minimize the impact of routing instabilities from other domains to unicast transit services in the backbone R1 is part of an OSPF- enabled network, and acts as an ASBR connected via interface GiO to the external domain The OSPF exponential backoff algorithm RFC 3623 with helper mode is already implemented on R1 Which additional configuration must the ISP_1 team apply to suppress routing instability for 3 minutes'?

A : Configure ip ospf resync-timtout 180 under the Gi0'1 interface configuration

B : Configure ip ospf timer nsf interval 3 under the global Gi0'1 interface configuration

C : Configure nsf ittf restart-inttrval 180 under the global OSPF configuration

D : Configure nsf ospf wait 3 under the global OSPF configuration

Answer: A

Question 3

Refer to the exhibit.

Refer to the exhibit. After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4. When the link from R2 is shut own as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the Branch office shows that traffic to HQ is still routed via R2. Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

A : nfigure two OSPF processes on R2 and R3 and redistribute traffic between them.

B : distribute routes from BGP to OSPF as type El.

C : multiarea adjacency to extend Area 10 to the link between R2 and R3.

D : eate a virtual channel from R3 to R4.

Answer: B

Question 4

Refer to the exhibit.IS-IS is the IGP for the network, where routers R1. R2 R3, and R4 are Level 1 routers in Area 12 and routers R5 and R6 are Level 2 routers m area 16 According to the network design router R1 must send traffic to R6 using R4 as its next hop To meet the requirement, a network engineer configured route filtering on R2 to prevent the route to R6 from being advertised from R2 However R1 is still using R2 as the next hop Which action must the engineer take to resolve the issue?

A : Disable wide area metrics and use only cost to perform the route manipulation.

B : Manipulate link costs to provide the desired routing through R4

C : Move all routers into the same IS-IS area

D : Configure routers R5 and R6 as Level 1 routers

Answer: D

Question 5

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$.
