Configure interface ge-0/0/3 to a mode trunk to assign the VLANs.

Configure VSTP on interface ge-0/0/1 to assign the VLANs.

On R1 and R3, include the loops 2 statement at the [edit protocols bgp family inet unicast] hierarchy.

On R1 and R3, include the advertise-peer-as statement at the [edit protocols bgp group external] hierarchy.

On R2, include the advertise-peer-as statement at the [edit protocols bgp group external] hierarchy.

7. You are asked to implement fault tolerant RPs in your multicast network.

Which two solutions would accomplish this behavior? (Choose two.)

Use BFD with statically defined RPs.

Use MSDP with statically defined RPs.

Router E receives Type 1 withdrawal messages from router

Router E receives Type 1 withdrawal messages from router

Router E receives Type 2 withdrawal messages from router

9. You are asked to configure 802.1X on your access ports to allow only a single device to authenticate.

In this scenario, which configuration would you use?

single supplicant mode

multiple supplicant mode

single-secure supplicant mode

MAC authentication mode

11. 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.)
