What should the administrator do to fix this problem?

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

Answer: B

Explanation:

MAC/IP overlap. 239.0.0.1 would be the same MAC for 224.0.0.1. 224.0.0.0/24 is always flooded over every port.
