Which two multicast listenerregistration protocols are supported in the Junos operating system? (Choose two.)

A. MLD

B. DVMRP

C. IGMP

D. PIM

Referring to the exhibit, anycast RP is implemented to ensure multicast service availability. The source is currently sending multicast traffic using group 239.1.1.1 and R3 is receiving PIM register messages, but R2 does not have active source information.

In this scenario, what are two methods to receive the active source information on R2? (Choose two.)

A. Configure an RP set in PIM on R1, allowing R1 to forward PIM register messages to R2 and R3 in the set.

B. Configure an MSDP protocol between R2 andR3.

C. Configure an RP set in PIM on R2 and R3, allowing the RPs to forward PIM register messages to the other RPs in the set.

D. Configure an MSDP protocol between R1 and R2.

Which two statements are correct regarding the behavior shown in the exhibit? (Choosetwo.)

A. The ge-1/1/0 interface is configured as secondary for Area 0.

B. The router is an ABR.

C. The router is not an ABR.

D. The ge-1/1/0 interface is configured as secondary for Area 100.

You aredeploying IP phones in your enterprise networks. When plugged in, the IP phones must automatically negotiate the power requirements for the new connection with the EX Series switches. In this scenario, which protocol should be used to enable this behavior?

A. CDP

B. MP-BGP

C. LLDP-MED

D. LLDP

Referring to the exhibit, which two statements are correct? (Choosetwo.)

A. The BGP neighbor can advertise L3 VPN related routes.

B. The BGP neighbor cannot advertise EVPN related routes.

C. The BGP neighbor can advertise EVPN related routes.

D. The BGP neighbor cannot advertise L3 VPN related routes.

Which address range is used for source-specific multicast?

A. 239.0.0.0/8

B. 233.0.0.0/8

C. 232.0.0.0/8

D. 224.2.0.0/16

A user is attempting to watch a high-definition video being streamed from the mediaserver over the network. However, the user complains that the experienced video quality is poor. While logged on to router B, a Juniper Networks device, you notice that video packets are being dropped.

In this scenario, what would solve this problem?

A. Adjust the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate.

B. Adjust the expedited-forwarding BA classifier to router B's ge-0/0/0 interface to support a higher transmit rate.

C. Adjust thescheduler-map to support a higher transmit rate.

D. Adjust the expedited-forwarding BA classifier on router B's ge-0/0/1 interface to support a higher transmit rate.

There are two BGP routes to 10.200.200.0/24 received from twoexternal peers. Route 1 comes from a neighbor with a router ID of 10.10.100.1 and a peer IP address of 10.10.30.1, and route 2 comes from a neighbor with a router ID of

10.10.200.1 and a peer IP address of 10.10.50.1. Both routes have the same MED value, origin value, AS path length, and local preference number.

In this scenario, which statement is correct about the active route?

A. Route 1 will be active because of the peer IP address.

B. Route 2 will be active because of the peer IP address.

C. Route 1 will be active because of the router ID.

D. Route 2 will be active because of the router ID.
