What is the function of Dynamic Host Configuration Protocol (DHCP)?

• A. To dynamically assign IP addresses to devices
• B. To access and maintain distributed directory information services
• C. To send system log messages to a server
• D. To share files and printers over a network

Answer: (A)

Dynamic Host Configuration Protocol automates IP address configuration by assigning addresses to devices as they join the network, along with other essential settings such as the subnet mask, default gateway, and DNS servers. This eliminates manual setup and helps prevent IP conflicts by managing addresses from a central pool with a leasing mechanism. A device typically goes through a DHCP exchange to obtain and renew these settings, ensuring it keeps valid network configuration without user intervention. The other options describe different network services (directory information, system logging, file/printer sharing) that are not the function of DHCP.
