Question 1

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 2

Refer to the exhibit.After maintenance to activate BGP neighbors connecting a new data center attached to R1, L3VPN customers attached to OSPF domain 100 lost connectivity to services in OSPF 200 and OSPF 300 However Unified MPLS services within OSPF 100 remain reachable Which action must the network engineer take to resolve the outage?

A : Reset the BGP session between R1 and R2

B : Activate BGP neighbors between the new data center and R2 and R3

C : Establish new MPLS LSPs from R1 to R2, R3 and R4

D : Raise the maximum prefix limit on R2 to 1560 or more

Answer: A

Question 3

RPL has several fundamental capabilities that differ from those present in configurations oriented to traditional route maps Routing policy language introduces the notion of sets Which group of set types is valid in RPL?

A : acl-path-set community-set pre-community-set prefix-set and bgp-set

B : as-path-set community-set. extcommunity-set prefix-set and rd-set

C : access-control-set, community-set post-community-set pre-prefix-set and routed-set

D : route-path-set, community-set in-community-set prefix-set and rd-set

Answer: B

Question 4

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 5

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
