NSE 4 – FortiGate 5.4 — Question 7

What statement describes what DNS64 does?

Answer options

• A. Converts DNS A record lookups to AAAA record lookups.
• B. Translates the destination IPv6 address of the DNS traffic to an IPv4 address.
• C. Synthesizes DNS AAAA records from A records.
• D. Translates the destination IPv4 address of the DNS traffic to an IPv6 address.

Correct answer: B

Explanation

The correct answer is B, as DNS64 primarily translates IPv6 addresses to IPv4 addresses to facilitate communication between different network protocols. Options A and C incorrectly describe the function of DNS64, while option D reverses the translation process by suggesting it converts IPv4 to IPv6, which is not accurate for DNS64.
