C. origin

D. next-hop

E. community

You have PIM SM multicast configured and running in a network environment comprised of EX4300 devices. Your customers report increased delay when switching channels using IPTV. To help decrease the delay, you implement PIM join load balancing. You add the set protocols pim join-loadbalance command to the configuration. After committing, you notice that the flows are still using only one path.

In this scenario, which statement is correct?

A. The clear pim join-distributioncommand must be issued.

B. The interfaces must be specified to use for load balancing.

C. IGMP snooping must also be configured.

D. PIM join load-balancing only works for PIM-DM.

A. It will rejected by term 2.

B. It will be accepted by term 1.

C. It will be accepted by the default policy.

D. It will be evaluated by the next policy.

There is a functioning OSPFv3 neighborship between Router-1 and Router-2 over the ge-0/0/1 link. However, the 172.100.100.0/24 and 172.101.101.100/24 routes are not being shared through OSPFv3.

Referring to the configuration shown in the exhibit, which two actions must you take to solve the problem? (Choose two.)

A. Add interface ge-0/0/1 under the IPv4 unicast realm for both routers.

B. Add the IPv6 family protocol under ge-0/0/2 for both routers.

C. Add the lo0 interface under OSPFv3 for both routers.

D. Add interface ge-0/0/2 under OSPFv3 for both routers.

A. Frames that exit interface ge-0/0/1 on the data VLAN will be tagged.

B. The phone will automatically be assigned a VLAN ID.

C. Voice frames that enter interface ge-0/0/1 will be forwarded as expedited forwarding traffic.

D. All frames that exit interface ge-0/0/1 will belong to the data VLAN.

What would be the cause of this problem?

A. Tunnel services have not been enabled on R1.

B. All routers have not been configured with the same Auto-RP discovery group.

C. R5 has not received an IGMP report of 224.1.1.1.

D. A(*,G) tree has not been built yet.

Which protocol is a multicast routing protocol?

A. OSPF

B. BGP

D. IS-IS

Your IPv4 multicast network uses different MX Series routers for the source DR and the PIM sparse-mode RP.

What is required before PIM register messages are exchanged between the DR and RP routers?

A. Add a tunnel services PIC to the RP router.

B. Add an adaptive services PIC to the DR router.

C. Enable tunnel services on the DR and RP routers.

D. Configure PIM encapsulation on the DR and RP routers.

Referring to the exhibit, which configuration statement would solve the problem?

B. set policy-options policy-statement NHS term BGP_ROUTES from external

C. set protocols bgp group BGP-MESH import NHS

D. delete protocols bgp group BGP-MESH export NHS
