Question 1

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 2

Refer to the exhibits.

All links inside the network are configured at a default cost of one inside the fully converged OSPF domain. Given the configuration from XR1, which interface does traffic from XR1 that is destined to the loopback interface of XR6 select for the exiting interface?

A : terface GigabitElhemet 0/0. The tie breaker of the node index priority is lower and trumps the path cost.

B : terface GigabitEthernet 0/1. The tie breaker of the path cost being lower. The node index priority does not impact this selection process.

C : terface GigabitEthernet 0/1. The tie breaker of the node index priority is lower and trumps the path cost.

D : terface GigabitEthernet 0/0. The tier breaker of the path cost being lower. The node index priority does not impact this selection process.

Answer: A

Question 3

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

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.OSPF is running in the core of a company. Router RA is running EIGRP. After the company acquired an additional office, an engineering team connected the two networks from router RA to router R1. OSPF and EIGRP have been mutually redistributed on R1. but the team cannot view the routes on R3. Which action must the team take to resolve the issue?

A : Create a virtual link between R1 and R2.

B : Configure the routers in Area 2 to be in Area 0.

C : Disable stub routing in Area 1.

D : Redistribute connected routes on R3.
