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.

An MPLS core network has connectivity issues R4 has failed. It impacts traffic loss between R1 and R8. Customers report no access to their file servers, which delays their transformation work. Which quick action resolves the issue until R4 recovers?

Options :

A : Implement Link and Node protection on routers R2 and R7.

B : Disable traffic engineering so that traffic prefers the IGP path

C : Enable MPLS TE fast reroute on router R1 and Link and Node protection on router R2.

D : Configure IBGP full mesh for faster convergence.

Answer: C

Question 3

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

Question 4

What is a requirement of PIM-SM?

Options :

A : It requires Cisco Express Forwarding to be enabled.

B : It must be enabled on loopback interfaces only

C : It requires OSPF to be configured on the network.

D : It must use an RP

Answer: D

Question 5

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?

Options :

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
