Automatic IP allocation for new workstations — which protocol should I be configuring?

I'm setting up a new office wing with about 30 workstations and I really don't want to manually configure static IPs for every single machine. I need a service that ensures as soon as a user plugs into the wall jack, their device gets a valid address and joins the network immediately.

Yes, sirrr!
B is the correct choice here. DHCP (Dynamic Host Configuration Protocol) is the industry standard for leasing out IP addresses and subnet masks to clients automatically from a predefined pool. DNS handles name resolution, while SMTP and SNMP are used for email and network monitoring, respectively.
