NSE7 Advanced Threat Protection Practice Question
An administrator configures FortiSandbox inline scanning for HTTP traffic. They notice that files uploaded via HTTP are being scanned but no verdict is being returned, causing delays. What is the MOST likely cause?
⚠ Common exam trap
A common mix-up: candidates assume a missing verdict is due to a registration or capacity issue, but the question specifically states scanning is occurring, which eliminates options A and B, and the delay points directly to a timeout configuration problem.

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 file scan timeout is too short, causing FortiGate to pass the file before a verdict is received
When FortiGate sends a file to FortiSandbox for inline scanning, it waits for a verdict before allowing the traffic to proceed. If the file scan timeout is too short, FortiGate will stop waiting for the verdict and pass the file anyway, causing the observed delay without a final verdict. This is the most likely cause because the administrator sees scanning occurring but no verdict returned, which aligns with a premature timeout rather than a failure to scan.
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 FortiSandbox has reached its maximum storage capacity
Why it's wrong here
Storage full would prevent new submissions, not cause delays without verdict.
- ✗
The FortiSandbox is not registered with the FortiGate
Why it's wrong here
Without registration, file submission wouldn't work at all.
- ✓
The file scan timeout is too short, causing FortiGate to pass the file before a verdict is received
Why this is correct
If FortiSandbox takes longer than the configured timeout, FortiGate allows the file to pass without a verdict.
- ✗
The file type is not supported by FortiSandbox
Why it's wrong here
Unsupported files are usually passed immediately without scanning.
