A network administrator notices that a switch is flooding frames out of all ports except the source port when trying to reach a specific device. What is the most likely cause of this behavior?
A hardware failure in the switch is causing improper frame forwarding.
The switch does not have the destination MAC address in its MAC address table.
The switch's MAC address table is full and cannot store new addresses.
The switch is experiencing a broadcast storm due to network loops.
When a switch receives a frame with a destination MAC address that is not in its MAC address table, it floods the frame out of all other ports to locate the destination device. This is standard behavior for switch learning. Other options like a full MAC address table or hardware failure could cause issues, but they would typically result in dropped frames or system errors rather than frame flooding.
