What would be the primary reason an attacker would launch a MAC address overflow attack?

so that the switch stops forwarding traffic
so that legitimate hosts cannot obtain a MAC address
so that the attacker can see frames that are destined for other hosts
so that the attacker can execute arbitrary code on the switch

Explanation: A MAC address overflow attack (or MAC flooding) aims to fill the switch's MAC address table with fake entries, forcing the switch to treat all subsequent incoming frames as unknown unicast traffic. When this happens, the switch floods those frames out of all ports on the VLAN, which allows the attacker to use packet sniffing software to capture and view data intended for other devices.
