QUESTION: 41

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?

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

QUESTION: 42

What is the purpose of a BGP confederation?

It reduces the number of iBGP peers and increases stability
It improves service by increasing the number of simultaneous iBGP peering sessions
It redirects traffic away from route reflectors, which reduces their operating load
It limits the number of routes a device receives from its peers, which reduces CPU load

QUESTION: 43

Refer to the exhibit. A network operator is configuring BGP PIC on CE1 on already established neighborships with PE1 and PE2 inside the fully converged MPLS network. Which element needs to be implemented to make this feature function effectively?

Bidirectional Forwarding Detection must be applied to the upstream facing BGP interfaces
The operator must ensure that all prefixes have the same next-hop from PE1 and PE2 for BGP PIC
A reserved BGP community of 1:10 must be used to denote the PIC feature set to the routing protocol
BGP import/export policies must be applied on all devices for the routes needing BGP for PIC

QUESTION: 44

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?
