The DHCP relay is responsible for forwarding DHCP messages between the DHCP server and the DHCP client, and assists the DHCP server in dynamically allocating network parameters to the DHCP client.
The correct answer is A. TRUE. A is correct because a DHCP relay agent (also called a DHCP helper) does exactly this: it intercepts DHCP broadcast messages from clients on one subnet and forwards them as unicast to a DHCP server on a different subnet, then relays the server's response back to the client…

Explanation
A is correct because a DHCP relay agent (also called a DHCP helper) does exactly this: it intercepts DHCP broadcast messages from clients on one subnet and forwards them as unicast to a DHCP server on a different subnet, then relays the server's response back to the client. This allows a single DHCP server to serve multiple network segments without requiring a server on each subnet.
B is incorrect because the statement is entirely accurate - there are no false elements to dispute.
Memory tip: Think of the DHCP relay as a "postal relay runner" - the client shouts (broadcasts) locally, the relay picks up the message and runs it to the distant server, then carries the reply back. No relay = the shout never leaves the local neighborhood.
