CCNA: Cisco Certified Network Associate — Question 602

A DHCP pool has been created with the name CONTROL. The pool uses the next to last usable IP address as the default gateway for the DHCP clients. The server is located at 172.16.32.15. What is the next step in the process for clients on the 192.168.52.0/24 subnet to reach the DHCP server?

Answer options

• A. ip helper-address 172.16.32.15
• B. ip default-gateway 192.168.52.253
• C. ip forward-protocol udp 137
• D. ip detault-network 192.168.52.253

Correct answer: A

Explanation

The correct answer is A, as using the 'ip helper-address' command allows the router to forward DHCP requests from clients on the subnet to the DHCP server at 172.16.32.15. Options B and D are incorrect since they configure a default gateway for the local network but do not facilitate communication with the DHCP server. Option C is irrelevant to the DHCP process and does not aid in reaching the server.
