A Network Administrator Is Managing a Network That Deploys a Multicast

A network administrator is managing a network that deploys a multicast service. The administrator has multiple streams successfully being routed by PIM-DM in the network. The administrator then adds a new stream with a destination address of 239.0.0.1. However, clients who have not joined the stream are receiving it. What should the administrator do to fix this problem?

A) Verify that IGMP is enabled between the switches connecting the multicast source and receivers
B) Change the destination multicast address to 239.1.1.1
C) Define the 239.0.0.1 stream on the rendezvous point (RP)
D) Define the 239.0.0.1 stream on the PIM candidate bootstrap router
