I was working with a junior admin the other day. He was playing with DHCP in the lab and he was having issues with comprehending how DHCP actually works. After setting up the DHCP server, authorizing and setting the scope up I asked him to explain the process a client goes through when requesting a automatic IP address from DHCP. He could not. So that brought me back to the old days and the acronym DORA. DORA stands for Discover, Offer, Request and Accept. If anyone ever asks you about the DHCP process simply say Discover, Offer, Request and Accept (not DORA!)
Do you have any admin words of wisdom for new admins recently getting into the business?
