Refer to the exhibit. After the power-on self test (POST), the system LED of a Cisco 2950 switch
turns amber. What is the status of the switch?

A.
The switch has experienced an internal problem but data can still be forwarded at a slower rate.

B.
The switch passed POST, but all the switch ports are busy.

C.
The POST was successful.

D.
POST failed and there is a problem that prevents the operating system of the switch from being
loaded.

E.
The switch has a problem with the internal power supply and needs an external power supply to
be attached.

Explanation:
While the switch powers on, it automatically begins POST, a series of tests that verifies that the
switch functions properly. When the switch begins POST, the system LED is off. If POST
completes successfully, the LED turns green. If POST fails, the LED turns amber.
