If more than one DHCP server is available on the local network, in which order will DHCP messages be sent between a host and a DHCP server?
- request, discover, offer, acknowledgment
- acknowledgment, request, offer, discover
- discover, offer, request, acknowledgment
- request, acknowledgment, discover, offer
Answers Explanation & Hints:
A DHCP host broadcasts a DHCP discover message to locate available servers. If more than one DHCP server is available, each server will respond to the host with a unicast DHCP offer message, which offers a lease to the client. The client then broadcasts a DHCP request message that identifies the specific server and offer that the client will accept. The identified server will unicast a DHCP acknowledgment message to finalize the offer.
