Which of the following is used when a workstation sends a DHCP broadcast to a server on another LAN?

Answer options

• A. Reservation
• B. Dynamic assignment
• C. Helper address
• D. DHCP offer

Correct answer: C

Explanation

The correct answer is C, Helper address, as it allows DHCP messages to be forwarded from one subnet to another.
