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.Enable tunnel services on the DR and RP routers.
• B.Configure PIM encapsulation on the DR and RP routers.
• C.Add an adaptive services PIC to the DR router.
• D.Add a tunnel services PIC to the RP router.

You are troubleshooting an OSPF adjacency issue between R1 and R2.

What is the reason for the ExStart state shown in the exhibit?

• A.R1 and R2 are using the same IP address.
• B.R2 was elected as the designated router.
• C.The MTU is not the default on R1 and R2.
• D.R1 was elected as the backup designated router.

You are enabling MSTP in your Layer 2 network to prevent loops. In this scenario, which three parameters must match on all switches in the network? (Choose three. )

• A.revision level
• B.max age
• C.bridge priority
• D.MSTI-to-VLAN mapping
• E.configuration name

You want to implement an RP in your PIM sparse mode environment, you are considering the advantages and disadvantages of the various RP election methods.
In this scenario, which three implementation guidelines are correct? (Choose three.)

• A.The auto-RP method includes the ability to maintain a backup RP.
• B.When multiple election methods are implemented on a device, the static method is preferred.
• C.With the bootstrap method, the primary criterion for electing a BSR is priority value.
• D.The static method requires configuration on all devices in the PIM domain.
• E.The auto-RP method requires using two PIM dense mode groups from the 323/8 range.
