You must ensure that r1's IPv4 loopback address exists in r3's inet 0 routing table.
Referring to the exhibit, which statement is true?

A.

An IPv4 unicast realm can be enabled on each router.

B.

A policy can be configured on r1 to redistribute 172.16.100.1/32 into OSPFv2, which would cause r3 to eventually learn the route and place it into inet 0.

C.

A RIB group can be configured on r3 to copy that route into inet 0 because 172.16.100.1/32 exists in r3's inet6.0 table.

D.

A policy can be configured on r1 to redistribute 172.16.100.1/32 into OSPFv3, which would cause r3 to eventually learn the route and place it into inet 0.

Exam JN0-661: Question 7 - Image 1

Referring to the exhibit, you have a network that uses PIM-SM and you need to block certain PIM register messages.
Which two statements are correct in this situation? (Choose two.)

A.

You should apply a policy that blocks PIM register messages from the source on R4.

B.

You should apply a policy that blocks PIM register messages from the source on R3.

C.

You should apply a policy that blocks PIM register messages from the source on R2.

D.

You should apply a policy that blocks PIM register messages from the source on R1.

Question 8 of 65

Which statements are true about NG MVPNs? (Choose two.)

A.

NG MVPN membership is signaled between PEs using PIM?

B.

Every NG MVPN PE router builds a selective provider multicast service interface tunnel to every other router in the same NG MVPN

C.

NG MVPN membership is signaled between PEs using MP-BGP.

D.

Customer multicast traffic can be transported over the provider network using point-to-multipoint MPLS LSPs.

Question 9 of 65

A service provider wants to start using all of their LSPs for internal traffic and not just their MPLS VPNs. Any solution must ensure that existing VPNs and routing policies will continue to function properly.
Which MPLS traffic engineering parameter would accomplish this task?

A.

bgp

B.

bgp-igp-both-ribs

C.

bgp-igp

D.

mpls-forwarding
