CCNA: Cisco Certified Network Associate — Question 538

Which command must be entered to configure a DHCP relay?

Answer options

• A. ip dhcp relay
• B. ip dhcp pool
• C. ip address dhcp
• D. ip helper-address

Correct answer: D

Explanation

The correct answer is D, 'ip helper-address', which is the command used to configure a router to forward DHCP packets to a DHCP server. Options A and B are not valid commands for configuring DHCP relay, and option C refers to obtaining an IP address via DHCP, which is unrelated to setting up a relay.
