Question 1

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?

Options :

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

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

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

D : Interface 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 2

Refer to the exhibit. Users connected to an application on 1.1.1.1 via routers CE1 and CE2 are complaining of frequent disconnections. While troubleshooting the issue, a network engineer with an employee ID: 4333:96:916 determined that the application itself is working normally, but the link connected to the 1.1.1.1 application is flapping. The users on CE1 and CE2 are accessing applications on 2.2.2.2 without difficulty. Which action resolves the issue?

Options :

A : Disable split horizon on router R2.

B : Redistribute CE1 routes on router R2.

C : Enable passive interface on the router R3 Loopback1 interface.

D : Enable route dampening on routers R1 and R2

Answer: D

Question 3

Refer to the exhibit.

Refer to the exhibit. A network engineer is configuring router R3 to handle multicast streams, but Host-2 cannot send subscriptions messages to the IPTV source. Which configuration must the engineer apply to router R3 so it passes the IPTV stream to Host-2?

Options :

A :

B :

C :

D :

Answer: D

Question 4

Refer to the exhibit. A network engineer must correct the security policy on the EDGE_R router, which is connected to two Tier 1 ISPs. After another engineer added ip as-path access-list 11 permit 11 to EDGE_R, some routes from AS 11 and AS 4832 started to appear in the routing information base (RIB). Traffic control via Community options is disabled on both ISPs. How should the network engineer update the router configuration on EDGE_R so that only routes for AS 11 are permitted?

Options :

A : Configure ip as-path prefix-list 11 permit _11$.

B : Configure ip as-path access-list 11 permit _11_.

C : Configure ip as-path distribution-list 11 deny A[0-9]+S.

D : Configure ip as-path access-list 11 deny 4832$.

Answer: D

Question 5

Refer to the exhibit. Mid-sized company Z connected two branch offices via a multicast-enabled ISP using the BGP routing protocol. PIM was implemented to support multicast streaming between the branches via MSDP Client A cannot connect to the multicast stream source of company Z. The network engineer ran a debug on the edge of the network as shown. Which action resolves the issue?

Options :

A : Implement MBGP and enable a multicast address family on R2

B : Configure the PIM protocol on the Serial 1/1 interface and enable Auto-RP

C : Deploy BSR on routers R1 and R2 and enable multicast on both LAN segments.

D : Enable the BGP routing protocol and advertise the 10 10.10.0/24 subnet on R1.
