Cisco CCNA 200-301 Practice Question
An administrator notices that a switch is forwarding frames out of all ports except the one they arrived on, even though the frames are destined for a specific device. What is the most likely cause of this behavior?
The switch's CPU is overloaded, causing it to forward frames incorrectly.
The switch is in standby mode.
The switch's MAC address table does not have an entry for the destination MAC address.
A routing protocol is incorrectly configured on the switch.
