Question

While designing your network's VLAN topology, your team has decided to use a centrally managed DHCP server rather than creating a separate DHCP server for each VLAN. What software will you need to make the central DHCP server accessible across VLANs?

Answer 1

DHCP relay agent

Step-by-step explanation:

A DHCP relay agent is any TCP/IP host that is used to forward request and replies between DHCP server and client when the server is present on the different network. Relay agents receive DHCP messages and then generate a new DHCP message to send out on another INTERFACE.

In order to use acentrally managed DHCP server rather than creating a separate DHCP server for each VLAN, the DHCP relay agent is configured to provide DHCP service to multiple VLANs. It does this by receiving messages that are DHCP related and creates it own to send beyond the broadcast domain.
