Which service provides automatic IP assignment and TCP/IP configuration information?

Which service provides automatic IP assignment and TCP/IP configuration information?

• A. DNS
• B. DHCP
• C. FTP
• D. SMTP

Answer: (B)

Automatic IP assignment and TCP/IP configuration is handled by a service that distributes IP addresses from a pool and provides essential network settings to devices, such as the subnet mask, default gateway, and DNS servers. This service, DHCP, streamlines network management by letting clients obtain their network details automatically, often through a quick four-step exchange (discover, offer, request, acknowledge) and by leasing addresses for a set period. DNS resolves domain names to IP addresses, but it does not assign IPs or configure TCP/IP; FTP is used for transferring files, and SMTP is used for sending email.
