Which two features control multicast traffic in a VLAN environment?

A (IGMP Snooping): Controls IPv4 multicast traffic within VLANs by listening to IGMP join/leave messages and forwarding multicast only to interested ports.

B (MLD Snooping): Performs similar multicast control for IPv6 multicast traffic by listening to MLD protocol messages.

Both technologies reduce unnecessary multicast flooding inside VLANs.

Why other options are incorrect:

C (RGMP): Controls multicast on router-connected ports, not intra-VLAN.

D (PIM Snooping): Operates on PIM-enabled Layer 3 devices; less relevant for pure VLAN-based Layer 2 multicast control.

E (Pruning): Refers to multicast tree pruning in Layer 3 multicast routing, not VLAN Layer 2 control.
