CompTIA Network+ (N10-006) — Question 31

A technician installs three new switches to a companys infrastructure. The network technician notices that all the switch port lights on the front of each switch flashes rapidly when powered on and connected. Additionally, there are rapid flashing amber lights on the switches when they started up the next day.
Which of the following describes what is occurring with the switches?

Answer options

• A. The switches are running through their spanning tree process.
• B. The switches are having problems communicating with each other.
• C. The switches are connected and detected a spanning tree loop.
• D. The switches are not functioning properly and need to be disconnected.

Correct answer: A

Explanation

The correct answer is A because the rapid flashing of the port lights indicates that the switches are completing their spanning tree protocol process, which is normal during startup. Options B and C suggest communication problems or loops, which are not indicated by the behavior described. Option D implies a malfunction, but the described behavior is typical during the initialization phase of spanning tree protocol.
