Question 1

Refer to the exhibit. Router R1 is expected to receive routes that originate from AS 65547 only. However, R1 is receiving routes from AS 65547 and several other ASs that are directly attached to it. Which change to the AS path permit filter corrects the problem?

Options :

A : Change the regular expression to $.

B : Change the regular expression to.*.

C : Change the regular expression to _65547_.

D : Change the regular expression to A65547$

Answer: D

Question 2

Refer to the exhibit.

Refer to the exhibit A network engineer installed a new router (router 3) at the regional hub running MPLS services for scalability Router 3 is connected to the 10.44 4.0,'24. 10.44 5.024. 10 44.6.0/24. and 10 44 7 0/24 subnets The new router has been configured for OSPF area 2. and it is advertising the four connected networks. The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders Which action resolves the issue?

Options :

A : On router 3, configure an access list to filter the networks.

B : On router 2, configure a route map to filter the networks.

C : Under the OSPF configuration on router 3. add area 2 range 10.44.4.0 255.255.252.0.

D : Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.

Answer: D

Question 3

A network consultant is troubleshooting IS-IS instances to identify why a routing domains is having communication problems between the two instances. Which description of the possible cause of issues in the routing domain is true?

Options :

A : The same interface cannot be advertised in two different IS-IS instances

B : The IS-IS ''ISP'' and ''ISP2'' instances are unrelated and unable to intercommunicate

C : The configured IS-IS NSEL value is not allowing the routing systems to establish a neighborship

D : The interface mode ip router is-is command was not included in the script

Answer: A

Question 4

Refer to the exhibit.

Refer to the exhibit. A network engineer configured three new PE routers to expand the network. The new routers run in the IS-IS routing protocol and reside in the data center in the same exchange as the existing routers. However, the network is now experiencing suboptimal routing. The Layer 2 configuration and VLANs are configured correctly to provide segregation between networks, but the Level 1 routes are not being converted to Level 2 routes. Which action resolves the issue?

Options :

A : On Router 1, redistribute the routes into IGP.

B : On Router 1, summarize internal routes between areas.

C : On Router 2, redistribute the routes into IGP.

D : On Router 2. summarize internal routes between areas

Answer: D

Question 5

Refer to me exhibit.

A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routers coming from ASN 64502. but allow all the others. For that purpose, the following AS Pam prefix 1st s being used:

What must be fixed to achieve this result?

Options :

A : The AS-PATH filter must be defined inside the route-map mode

B : At the end ip as-path access-list 10 permit .* must be included

C : The statement must be modified with ip as-path access-list 1 deny _64502_

D : The statement must CM modified with ip as path access list 1 deny A64502$

Answer: B
