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.
A routing protocol is incorrectly configured on the switch.
The switch is in standby mode.
The switch's MAC address table does not have an entry for the destination MAC address.
