NSE7 Advanced Threat Protection Practice Question
A company wants to use FortiMail to implement email authentication to prevent spoofing. Which THREE mechanisms should be configured in FortiMail's Authentication Profile?
⚠ Common exam trap
Test-takers frequently confuse transport security (TLS) or client-side encryption (S/MIME) with server-side domain authentication mechanisms, leading them to select options that protect confidentiality or integrity but do not prevent spoofing.

Correct answer & explanation
✓
DMARC
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is correct because it builds on SPF and DKIM to provide a policy framework that tells receiving mail servers how to handle messages that fail authentication checks. In FortiMail's Authentication Profile, DMARC enables the enforcement of policies like quarantine or reject, which directly prevents spoofing by ensuring only authenticated emails are delivered.
