Question 81

Which two functions are supported for BGP extension MP-BGP for IP multicasting? (Choose two.)

A.A network can support congruent unicast and multicast topologies.

B.MP-BGP is an enhanced BGP that carries routing information for multiple network layer protocols and IP multicast routes.

C.MP-BGP is useful when a link dedicated to multicast and unicast traffic is desired.

D.A network can support incongruent unicast and multicast topologies.

E.MP-BGP carries single sets of routes for unicast routing and multicast routing.

Question 82

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?

A.Configure all routers as Level 1 routers.

B.Remove the link metric for the link from router R1 to router R2.

C.Change the link metric for the link from router R1 to router R2 to 1.

D.Configure all routers as Level 1 / Level 2 routers.

Question 83

Which feature is used in multicast routing to prevent loops?

A.RPF

B.STP

C.inverse ARP

D.split horizon

Question 84

Refer to the exhibit.

How are packets directed through the data plane when SRv6 is implemented?

A.The packet is encapsulated with a header and trailer encoding the ordered list of segments

B.An ordered list of segments is encoded in a routing extension header

C.A stack of labels represents an ordered list of segments

D.The MPLS data plane is used to push labels onto IGP routes

Question 85

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?

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

B.The interface mode ip router is-is command was not included in the script

C.The same interface cannot be advertised in two different IS-IS instances

D.The IS-IS "ISP" and "ISP2" instances are unrelated and unable to intercommunicate
