Which two statements correctly describe the RPF check when a multicast packet arrives at a
router? (Choose two.)

A.
The router looks up the source address in the unicast routing table to determine if the packet
has arrived on the interface that is on the reverse path back to the source

B.
The router looks up the destination address in the unicast routing table to determine if the
packet has arrived on the interface that is on the reverse path back to the destination

C.
If the packet has arrived on the interface leading back to the destination, the RPF check passes
and the packet is forwarded. If the RPF check fails, the packet is dropped

D.
If the packet has arrived on the interface leading back to the source, the RPF check passes and
the packet is forwarded. If the RPF check fails, the packet is dropped
