When a client and server are not on the same physical network, which device is used to forward requests and replies between client and server for DHCP?
When a client and server are not on the same physical network, the device used to forward requests and replies between client and server for DHCP is the DHCP relay agent. A DHCP relay agent is a network device, such as a router or switch, that receives DHCP requests from clients on one subnet and forwards them to a DHCP server on another subnet. It also relays the responses from the DHCP server back to the client. This allows DHCP clients to obtain IP addresses and other configuration information even if the DHCP server is not on the same physical network.
B is correct. A DHCP relay agent is any host that forwards DHCP packets between clients and servers. Relay agents are used to forward requests and replies between clients and servers when they are not on the same physical subnet. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_dhcp/configuration/15-sy/dhcp-15-sy-book/dhcp-relay-agent.html#GUID-9E110360-34EA-40BB-9314-2AFABD7F2FDA
When a client and server are not on the same physical network, the device used to forward requests and replies between the client and server for DHCP is a DHCP relay agent. The DHCP relay agent is a network device, such as a router or switch, that operates at the network layer (Layer 3) of the OSI model. Its purpose is to receive DHCP client messages broadcasted on one network segment and then forward them to a DHCP server on a different network segment. Similarly, it receives DHCP server messages and relays them back to the DHCP client. By using a DHCP relay agent, DHCP messages can traverse multiple network segments, allowing DHCP clients to obtain IP addresses and other configuration information from DHCP servers located on different networks.
B is accurate and correct
