Which port does DHCP use for client connections?

Answer options

• A. UDP port 67
• B. UDP port 68
• C. UDP port 69
• D. UDP port 66

Correct answer: B

Explanation

DHCP uses UDP port 68 for client connections, which allows clients to receive their IP address and other configuration settings from the DHCP server. The other options are incorrect as UDP port 67 is used by the server, while ports 66 and 69 are not associated with DHCP operations.
