Which statement best describes why DHCP is used in large networks?

• A. It dynamically assigns IP addresses to a large number of computers, reducing manual configuration
• B. It requires manual IP assignment for all devices
• C. It only assigns DNS servers
• D. It encrypts traffic

Answer: (A)

Automating IP address management is crucial in large networks because there are many devices that must have unique addresses without creating a lot of manual work. DHCP serves as a centralized service that automatically assigns IP addresses, subnet masks, default gateways, and other network settings to devices as they connect. When a device starts up, it uses a DHCP exchange to discover a server, which offers an address, the device requests it, and the server finalizes with an acknowledgment. This leasing system allows addresses to be reused when devices disconnect, and administrators can control ranges (scopes), reserve addresses for important devices, and provide options like DNS servers and other config details. The result is scalability, fewer configuration errors, and easier management across hundreds or thousands of devices. In contrast, manual IP assignment requires configuring each device individually, which is impractical in large networks. DHCP also is not about encrypting traffic, and it does more than assign DNS servers—it handles the actual assignment of IP addresses and related network settings.
