Explanations

A network technician at a small office upgrades the LAN switch.

After the upgrade, a user reports being unable to access network resources.

When the technician checks the switchport, the LED light is not lit.

Which of the following should the technician check FIRST?

A.

The device is using the correct cable type.

B.

The switchport is functioning properly.

C.

The device is connected to the switch.

D.

The switch is connected to the router.

C.

The first thing the technician should check is whether the device is actually connected to the switch or not. This is because if the device is not connected to the switch, then it won't be able to access the network resources and the LED light on the switchport will not be lit. Therefore, option C is the correct answer.

If the device is not connected to the switch, the technician should ensure that the device is properly connected to the switch using the correct cable type (Option A). This is because using the wrong cable type could result in connectivity issues.

Once the device is properly connected to the switch, the technician should check if the switchport is functioning properly (Option B). The technician can do this by checking the switchport configuration and ensuring that it is configured correctly.

If the switchport is functioning properly, the technician should then check if the switch is connected to the router (Option D). This is important because if the switch is not properly connected to the router, then the network resources won't be accessible.

In summary, the technician should check the following in the following order:

  1. The device is connected to the switch.
  2. The device is using the correct cable type.
  3. The switchport is functioning properly.
  4. The switch is connected to the router.
