What is DHCP's role in a network?

• A. It assigns domain names to devices
• B. It stores DNS records
• C. It automatically assigns IP addresses to clients
• D. It negotiates firewall rules

Answer: (C)

DHCP's role is to automatically assign IP addresses to clients on a network, along with other necessary configuration like the subnet mask, default gateway, and DNS server information. This makes it easy for devices to join the network without manual setup and helps prevent IP conflicts by issuing unique addresses from a defined pool. The typical process involves the client asking for an address, the server offering one with a lease, the client requesting it, and the server confirming with an acknowledgment, after which the device uses that IP for a period before the lease expires or is renewed. The other tasks described belong to DNS (domain name resolution and DNS records) or firewall management, not DHCP.
