When troubleshooting an error in Mike’s network, you observe that the IP address of his PC changed after the PC was restarted. What is your inference from this?
  1. Computer has a DHCP-based IP address
  2. DNS server is offline
  3. DHCP server is offline
  4. Ethernet cable is a faulty
Explanation
Answer - A - If the IP address changes after a reboot, then it is most likely that the computer is using DHCP.

Key Takeaway: Generally (though not always), if a computer uses DHCP, the computer obtains a different IP address soon after the computer boots up. If the IP address changes when the PC is booted, then the computer is configured with a DHCP-based address.
