After configuring IS-IS on routers R1 and R2, an engineer notices that only the loopback interface at 2000:1::1 /96 is known to router R2. Which change must be made so that only Loopback2 is advertised from R1 to R2?

A.

Configure the router isis areal command under the LoopbackO interface on R1.

B.

Remove the advertise passive-only command under the IS-IS address family ipv6 configuration

C.

Remove the ipv6 router isis areal command under the Loopback2 interface on R1.

D.

Remove the passive-interface Loopback0 command under the router isis areal configuration.

Question # 63

Refer to the exhibit.

An engineer applied the summarization configuration on R1 for four networks (192.168.20.0/24 to 192.168.23.0/24) in area 1 and eight networks (192.168.32.0/24 to 192.168.39.0/24) in area 2 to stop the flooding of all the customer routes. While checking the routing table of R2, the engineer noticed that R1 is still sending only specific routes to R2. Which configuration should the engineer apply on R1 to summarize routes?

A.

B.

Option B

C.

Question # 64

Which difference should be considered when intradomain or interdomain multicast routing is implemented?

A.

Interdomain multicast routing requires an IS-IS or OSPF neighbor relationship between the domains but intradomain multicast routing requires only BGP

B.

Interdomain multicast routing relies on PIM-DM and intradomain multicast routing relies on PIM-SM.

C.

interdomain multicast routing uses BIDR-PIM to establish neighbor relationships between AS and interdomain multicast routing uses MSDP

D.

A network uses intradomain multicast routing without interdomain routing but networks that use interdomain multicast routing must also apply intradomain routing
