What function does a DHCP Relay provide?

Transmits TFTP requests between clients and servers
Forwards DHCP requests to another subnet
Directly assigns IP addresses to devices
Establishes IPSEC tunnels for IP traffic

The correct answer is: Forwards DHCP requests to another subnet

A DHCP Relay plays a crucial role in network environments where clients and DHCP servers are located on different subnets. Its primary function is to forward DHCP requests from clients to DHCP servers that are not on the same local subnet. When a client device requires an IP address, it broadcasts a DHCPDISCOVER message to the local subnet. If there is no DHCP server within that subnet to respond to the request, the DHCP Relay captures this message and forwards it to a DHCP server located on another subnet, which can then allocate an appropriate IP address and send the information back through the relay. The other options describe functions that are unrelated to DHCP Relay. For instance, transmitting TFTP requests relates to file transfers and not IP address assignments, while directly assigning IP addresses is a primary function of a DHCP server, not a relay. Establishing IPSEC tunnels pertains to creating secure communication channels for IP traffic, further emphasizing that the relevance of these processes does not apply to the role of a DHCP Relay.
