Which of the following ports is not associated with DHCP?

Port 67 (UDP)
Port 68 (UDP)
Port 53
Port 69 (UDP)

The correct answer is: Port 53

The correct choice is based on the specific roles of the listed ports in networking. DHCP, or Dynamic Host Configuration Protocol, uses certain ports for its operations, namely: - Port 67 (UDP), which is used by the DHCP server to receive client requests. - Port 68 (UDP), which is used by the DHCP client to receive messages from the server. Port 53 is associated with DNS (Domain Name System) services, which resolves domain names into IP addresses. This port does not play a role in the DHCP process, making it the correct answer. Port 69 (UDP) is designated for TFTP (Trivial File Transfer Protocol), which is unrelated to DHCP and serves a different purpose in networking. Thus, while it is also not used by DHCP, it is not the primary focus of this question, which specifically seeks the port that is fundamentally tied to DHCP functionalities.
