Which statement describes the relationship between domain names and IP addresses?

• A. It is a human-readable label that DNS resolves to an IP address
• B. It is a physical address on the network
• C. It directly carries the payload without DNS
• D. It is a broadcast address

Answer: (A)

Domain names are the friendly labels people remember, while IP addresses are the numerical addresses computers use to locate devices on the network. DNS acts like a phonebook for the Internet: it translates a domain name into the corresponding IP address so data can be routed to the right computer. When you enter a web address, your device asks DNS to resolve it, gets back the IP, and then sends packets to that address. That mapping—from a human-friendly name to a machine-ready address—is exactly what this statement describes. The other ideas aren’t accurate: a domain name isn’t a physical network address like a MAC address, it doesn’t carry the actual data (payload) itself, and it isn’t a broadcast address used for sending to all devices.
