Networking Fundamentals — Question 53

Which of the following services masks internal IP addresses from outside the network?

Answer options

• A. DHCP
• B. WINS
• C. NAT
• D. DNS

Correct answer: C

Explanation

NAT (Network Address Translation) is responsible for translating private IP addresses to a public IP address, effectively masking the internal addresses from the outside world. DHCP (Dynamic Host Configuration Protocol) assigns IP addresses to devices on a network, WINS (Windows Internet Name Service) resolves NetBIOS names to IP addresses, and DNS (Domain Name System) translates domain names to IP addresses, but none of these services provide the IP address masking that NAT does.
