   A DHCP server administrator is troubleshooting a report of IP address conflicts. In a pcap, they see a DHCPREQUEST from a client with the 'Requested IP Address' option set to 192.168.1.50, and the server responds with a DHCPNAK. The client then sends a new DHCPDISCOVER. Which of the following is the most likely reason for the DHCPNAK?

   • AThe DHCPREQUEST was sent as a broadcast, which the server does not support.
   • BThe requested IP address is already in use by another device, so the server rejected the request.
   • CThe server is configured to only respond to DHCPINFORM messages, not DHCPREQUEST.
   • DThe client's DHCPDISCOVER was not received by the server, so it sent a NAK to force a new discover.
