In the static LACP mode, the correct description of the active link selection is: (Multiple Choice)

- C . The router receives the multicast packet but fails the RPF check and discards the received multicast packet.
- D . There are two RPF check functions. One is to prevent loops in multicast routes, the other is to prevent forwarding of redundant multicast data packets.
