This NSE7 practice question tests your understanding of advanced threat protection. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
The file type is not supported by FortiSandbox
Why it's wrong here
Unsupported files are usually passed immediately without scanning.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often 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.
Detailed technical explanation
How to think about this question
In inline scanning mode, FortiGate uses the 'set scan-timeout' parameter under the FortiSandbox configuration to control how long it waits for a verdict. The default timeout is 30 seconds, but if the file requires deep analysis (e.g., sandbox execution), the scan may exceed this, causing FortiGate to apply a 'pass' action based on the 'action-on-timeout' setting. This behavior is defined in the FortiOS CLI under 'config system fortisandbox' and can be verified with 'diagnose debug application sslvpn -1' or similar debug commands for HTTP traffic.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the NSE7 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
