Refer to the exhibit.

An engineer has successfully fixed BGP peering issue. R1 has an established eBGP peering with R2 and R3. Which mechanism should the engineer apply in order to steer the traffic correctly?

A. The MED attribute can be applied on R2 to influence R1 to use it as the primary path.

B. The local preference attribute can be applied on R3 to influence AS 65513 to use AS 65515 as the secondary path.

C. The weight attribute can be applied on R2 to influence AS 65513 to use AS 65515 as the primary path.

D. The IGP metric can be manipulated on R1 to allow traffic to be load balanced between R2 and R3.

An ISP has an MPLS VPN-based network with 12 PE routers.

A. 60

B. 66

C. 78

D. 84

Refer to the exhibit

Networks 172.16.31.0/24 and 172 16 30.0/24 are advertised in area 34. and network 172.22 10.0/24 is advertised in area 0.

A recent security review discovered that users connected to routers R1 and R2 have been making unauthorized access to an application running on network 172 16 31 0/24

An engineer determined that routers R1 and R2 are receiving updates for network 17 16 31 0/24

Which action resolves the issue?

A. Apply route filtering on routers R3 and R4.

B. Apply route filtering on router R3 only.

C. Apply route filtering on routers R1 and R2

D. Apply route filtering on router R4 only.

Refer to the exhibit

After recent configuration changes to a customer's network, a network engineer notices that R2 cannot communicate with R3 Both FastEthemet interfaces on R2 and R3 are up and configured with the correct IP addresses MD5 password configured en R2 and R3 match with no issues.

What is the minimum change the engineer must make to enable R2 and R3 to communicate and fix the problem?

A. Configure a loopback interface on R2 and assign it to area 0.

B. Define area 2 as a NSSA on R2 and R3

C. Configure virtual links between RI and R3.

D. Configure interface F0/0 on RI and R2 to be in area O.

Refer to the exhibit.

An engineer is troubleshooting an issue with traffic steering using the color-only automated steering mechanism. BGP is failing to automatically steer traffic into an SR policy with the given color of a route, regardless of the next hop.

The layer 2 configuration is correct, and the physical connection between the devices is working normally.

Whch additional command sequence must the engineer add to correct the issue?

A. Cisco(config)# segment-routingCisco(config-sr)# traffic-engCisco(config-sr-te)# policy P1Cisco(config-sr-te-policy)# color 1 end-point ipv4 0.0.0.0

B. Cisco(config)# segment-routing traffic-engCisco(config-sr-te)# policy P1Cisco(config-sr-te-policy)# color 1 end-point ipv4 1.1.1.1Cisco(config-sr-te-policy )# autoroute Cisco(config-sr-te-policy-autoroute)# include all

C. Cisco(config)# segment-routingCisco(config-sr)# traffic-engCisco(config-sr-te)# policy P1Cisco(config-sr-te-policy)# color 1 end ipv4 1.1.1.1Cisco(config-sr-te-policy)# autoroute include all

D. Cisco# configureCisco(config)# segment-routingCisco(config-sr)# traffic-engCisco(config-sr-te)# policy P1Cisco(config-sr-te-policy)# color 1 end-point

Which technique should be permitted on ASA Firewall to allow MSDP Peering?

A. PIMv2 messages carrying MSDP messages

B. Multicast BGP carrying MSDP messages

C. UDP socket(s) carrying MSDP messages

D. TCP socket(s) carrying MSDP messages
