Question #: 4
Topic #: 1
[All Cisco Certified Support Technician (CCST) Networking Questions]

A support technician examines the front panel of a Cisco switch and sees 4 Ethernet cables connected in the first four ports. Ports 1, 2, and 3 have a green

LED. Port 4 has a blinking green light.

What is the state of the Port 4?

Show Suggested Answer Hide Answer
Suggested Answer: C

On a Cisco switch, a port with a blinking green LED typically indicates that the port is up (active) and is currently transmitting or receiving data. This is a normal state indicating active traffic on the port.

* A. Link is up with cable malfunctions: Usually indicated by an amber or blinking amber light.

* B. Link is up and not stable: Not typically indicated by a green blinking light.

* D. Link is up and there is no activity: Would be indicated by a solid green light without blinking.

Thus, the correct answer is C. Link is up and active.


* Cisco Switch LED Indicators

* Cisco Ethernet Switch LED Patterns

If the light was flashing Morse code, I might have gone with option B. But C is the winner here.

I'm surprised the technician didn't ask the switch 'Hey, how's it hanging?' to get a more detailed status update.

A blinking green light usually means the port is transferring data, so option C is the way to go.
