Which protocol would you use to dynamically obtain an IP address from a server on a local network?

• A. Dynamic Host Configuration Protocol (DHCP)
• B. Network Time Protocol (NTP)
• C. Simple Mail Transfer Protocol Secure (SMTPS)
• D. Remote Desktop Protocol (RDP)

Answer: (A)

Dynamic IP address assignment on a local network is handled by DHCP. When a device connects, it can automatically obtain its IP configuration from a DHCP server without manual setup. The client broadcasts a DHCPDISCOVER to find a server, the server responds with a DHCPOFFER proposing an IP and other settings (subnet mask, gateway, DNS). The client then sends DHCPREQUEST to accept the offer, and the server confirms with DHCPACK, granting the IP for a lease period. This makes devices seamlessly join and move within the network without reconfiguring addresses, which is essential in networks with many devices or frequent changes. Other options serve different purposes: network time synchronization, secure email transfer, and remote desktop access, none of which provide the IP address and network configuration a device needs to communicate on the local network.
