Question 1

Refer to the exhibit.The four routers in this network have formed adjacencies. Router R2 is an IS-IS level 1-2 router that connects to other areas, and the attach bit is set in the R2 level 1 LSP advertisements to R1. According to the network design, R2 should push level 2 routes from its routing table to the R1 routing table. However, R1 installed a default route in its routing table. Which action resolves this problem?

A : Use The is-type level-1-2 backdoor command lo unset the attach bit on R1 and use a prefix List to filter prefixes from R2

B : Set the attach bit on R1and use a prefix list to filter prefixes from R2.

C : Use the is-type level-1-2 backdoor command to unset the attach bit on R2 and configure a distribute-list to redistribute prefixes to R1

D : Configure R2 as a level 1 router and use a prefix list to filter prefixes to R1.

Answer: C

Question 2

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 3

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 4

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.

Answer: C

Question 5

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 : nfigure all routers as Level 1 routers.

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

C : ange the link metric for the link from router R1 to router R2 to 1.

D : nfigure all routers as Level 1 / Level 2 routers.

Answer: C
