NSE 4 – FortiGate Administrator 7.6 — Question 40

An administrator configures FortiGuard servers as DNS servers on FortiGate using default settings.

What is true about the DNS connection to a FortiGuard server?

Answer options

• A. It uses UDP 53.
• B. It uses DNS over HTTPS.
• C. It uses DNS over TLS.
• D. It uses UDP 8888.

Correct answer: C

Explanation

The correct answer is C because FortiGate uses DNS over TLS to secure DNS queries to FortiGuard servers by encrypting them. Option A is incorrect as standard DNS uses UDP 53, but FortiGate employs DNS over TLS instead. Options B and D are also incorrect as they reference different protocols and ports that are not used for FortiGuard DNS connections.
