Networking Fundamentals — Question 38

This question requires that you evaluate the underlined text to determine if it is correct.
The protocol that maps IP addresses to a Media Access Control (MAC) address is Domain Name Systems (DNS).
Review the underlined text. If it makes the statement correct, select "No change is needed." If the statement is incorrect, select the answer choice that makes the statement correct.

Answer options

• A. Address Resolution Protocol (ARP)
• B. Dynamic Host Configuration Protocol (DHCP)
• C. Routing Information Protocol (RIP)
• D. No change is needed

Correct answer: A

Explanation

The correct answer is A, Address Resolution Protocol (ARP), because ARP is the protocol responsible for mapping IP addresses to MAC addresses. The other options, DNS, DHCP, and RIP, serve different functions; DNS resolves domain names to IP addresses, DHCP assigns IP addresses to devices, and RIP is used for routing information exchange.
