Question:
A PC is not able to connect to a wired network. Pinging the loopback address is successful, but the gateway cannot be reached. On the network switch all the interface lights are on, except for the interface connected to the PC. The LED on the network card is off. What is the most likely cause of this problem?

  • The gateway needs to be fixed.
  • The network cable is faulty.
  • The network switch is faulty.
  • The PC has an incorrect IP address for the DNS server.

Explanation: The network card is working if the loopback address can be pinged. The LED on the network card being off points towards a faulty cable or a bad connection.
