DNS is conceptually like translating a street address to GPS coordinates. Which option represents the GPS coordinates concept?

• A. GPS coordinates
• B. IP address
• C. Email address
• D. MAC address

Answer: (A)

The key idea is the look-up that turns a human-friendly name into a precise destination you can reach. In the street address to GPS coordinates analogy, the GPS coordinates represent the exact location you’d use to find or reach the resource. That makes this option the best fit because it embodies the “where to go” aspect of the lookup. The other identifiers serve different roles: an IP address is the actual numeric locator routers use to route to the host, a MAC address is a hardware identifier, and an email address is an inbox identifier. None captures the exact destination in the same spatial sense as GPS coordinates. So the GPS coordinates option is the most appropriate representation of the GPS coordinates concept.
