A technician suspects that a new switch is the source of a network problem. While troubleshooting, the technician notices a blinking green activity LED on some of the ports. What does this indicate?

• There are no cables plugged into the ports.
• The power supply is the source of the problem.
• The ports are operational and are receiving traffic.
• The ports are operational, but no traffic is flowing.

Explanation: Most devices will have activity LEDs, which are often called link lights. A normal condition is for these LEDs to flash indicating that traffic is flowing through the port. A solid light typically indicates a device is plugged in, but no traffic is flowing. No light can indicate that nothing is plugged into the port, that there is no power to the device, or there is a cabling issue.
