A _____________________   enables the DHCP server to provide addresses from more than one scope to clients on the same physical subnet. This is helpful when clients within the same subnet have more than one IP network and thus need IPs from more than one address pool.

An easy way to remember how DHCP works is to learn the acronym DORA. DORA stands for ___________  ___________ Request, and Acknowledge.
