NSE 4 – FortiGate 6.2 — Question 40

An administrator wants to configure a FortiGate as a DNS server. FotiGate must use a DNS database first, and then relay all irresolvable queries to an external
DNS server. Which DNS method must you use?

Answer options

• A. Recursive
• B. Non-recursive
• C. Forward to primary and secondary DNS
• D. Forward to system DNS

Correct answer: A

Explanation

The correct choice is 'A. Recursive' because this method allows the FortiGate to first check its DNS database for answers and then search external DNS servers for any unresolved queries. The other options do not provide the same functionality; 'B. Non-recursive' does not check external servers, 'C. Forward to primary and secondary DNS' is not the same as utilizing a DNS database first, and 'D. Forward to system DNS' lacks the database checking process.
