What is Dynamic Host Configuration Protocol (DHCP), and what is it used for?
Dynamic Host Configuration Protocol, also known as DHCP, is a network protocol used to locate websites that computer users are trying to reach. As a site reliability engineer, you may not work directly with DHCP, but you should know what it is and be able to define it for the interviewer. The more familiar you are with the technology you will be engaging with, the better qualified you will be for this role and the more likely you will be to be hired.
"Dynamic Host Configuration Protocol is a network management procedure used on the internet and local networks to find a website, computer, user, or another asset a computer user is looking for. The address of the asset is known as the Internet Protocol or IP address. A DHCP server dynamically assigns an IP address and other network configuration parameters to each device on the network. This allows them to communicate with each other as well as with other devices, nodes, or users on the network. You could think of DHCP as the computer's address book."
