The customer called because she couldn't connect to the internet even though the light on her computer's network interface card (NIC) was lit. You tell her that while the light indicates her NIC is receiving a connection, there could still be other problems preventing her from reaching the internet. The light only means the NIC is connected to the network, not necessarily the internet.

1. You get a call from a customer who says that she can’t connect to the Internet. She
doesn’t understand why, since the status indicator light is lit on her computer’s NIC.
What do you tell her?
A. You say the light is lit on her NIC only when there’s a network interruption and is dark
when the computer is receiving a connection.
B. You tell her that the color of the NIC’s light indicates its status, and if it’s green,
it’s okay, but amber means it has a fault.
C. You tell her that the light just means the NIC is getting power but not that it is connected to
the network.
D. You tell her that the light indicates the NIC is receiving a connection but there could be other
problems preventing her from reaching the Internet.
Solution
D. The status indicator light on a NIC means it’s receiving power and a network connection,
but it doesn’t guarantee that the customer has an Internet connection. Usually, a solid green
light will indicate a network connection, while a blinking green light indicates an intermittent
connection.
