What does DHCP do?

• A. Dynamically assigns IP configuration to devices.
• B. Resolves domain names to IP addresses.
• C. Routes packets between networks.
• D. Filters traffic by MAC address.

Answer: (A)

DHCP dynamically assigns IP configuration to devices. When a device joins a network, DHCP automatically provides an IP address, subnet mask, default gateway, and typically DNS servers, along with a lease duration. This keeps devices correctly configured without manual setup and helps prevent IP address conflicts. Other options refer to different network services: domain name resolution is handled by DNS, which translates readable names into IP addresses; routing between networks is done by routers; and MAC address filtering is a security feature that allows or blocks devices based on their hardware address.
