Which selection is a reason why IGMP snooping should be configured on a switched network?
A . IGMP snooping populates the snooping table with the results of DHCP requests and can be used by Dynamic ARP Inspection to block IP spoofing attacks at Layer-2.
B . IGMP snooping verifies the source IP address of every IPv4 packet to ensure that it hasn’t been originated from a port different than its return path.
C . IGMP snooping is used to filter ping requests and results to avoid overflowing the MAC address table of the switch.
D . IGMP snooping allows a Layer-2 switch to limit the transmission of multicast frames to only the ports that have members of the relevant IGMP group.
