NSE7 Advanced Threat Protection Practice Question
A FortiGate administrator configures an antivirus profile with the machine learning engine enabled and applies it to a policy inspecting HTTP traffic. After deployment, the admin notices that some files are being allowed that should have been detected. What is the MOST likely cause?
⚠ Common exam trap
Candidates often assume the ML engine always blocks threats by default, overlooking the distinct monitor-only mode that logs detections without enforcement.
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 ML engine is in monitor-only mode
The most likely cause is that the machine learning engine is configured in monitor-only mode. In this mode, the ML engine will log detections and generate alerts but will not take any action to block the file, allowing it to pass through the policy. This is a common initial deployment strategy to assess the ML engine's impact before enabling active blocking.
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 is in monitor-only mode
Why this is correct
Monitor mode logs detections but does not block. To block, the engine must be in protect mode.
- ✗
FortiGuard outbreak prevention is disabled
Why it's wrong here
Outbreak prevention updates signatures frequently, but ML engine detection is independent.
- ✗
The antivirus profile is using flow-based inspection instead of proxy-based
Why it's wrong here
ML engine works in both modes; this is not the primary cause.
- ✗
The file size exceeds the maximum scanning limit
Why it's wrong here
File size limits affect scanning, but ML engine can handle large files; this would not allow known malware.
