NSE7 Advanced Threat Protection Practice Question
A FortiGate administrator configures an antivirus profile with Machine Learning (ML) engine enabled. The ML engine is not detecting any threats, even though new unknown malware is present. What is the MOST likely reason?
⚠ Common exam trap
Many exam-takers assume the ML engine works independently of subscriptions or that flow-based inspection disables it, when in fact the engine's effectiveness is entirely dependent on current FortiGuard updates.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The FortiGuard antivirus subscription is expired, preventing ML model updates
The FortiGate ML engine relies on FortiGuard for model updates that enable it to detect new and unknown malware. If the FortiGuard antivirus subscription is expired, the ML engine cannot receive these updates, rendering it unable to identify novel threats. This is the most likely reason the ML engine is not detecting any threats despite the presence of new unknown malware.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The ML engine requires a separate subscription
Why it's wrong here
ML engine is included with FortiGuard antivirus subscription.
- ✗
The ML engine is only for outbreak prevention
Why it's wrong here
ML engine is for real-time detection, not just outbreak.
- ✓
The FortiGuard antivirus subscription is expired, preventing ML model updates
Why this is correct
ML engine needs updated models from FortiGuard; expired subscription stops updates.
- ✗
The antivirus profile is set to flow-based inspection
Why it's wrong here
ML engine works in both flow and proxy modes.
