The answer is that three conditions must be met for FortiSandbox file submission on FortiGate: a valid FortiSandbox license, the file type must be in the supported list (e.g., PE, PDF, Office documents), and the FortiGate must have network connectivity to the FortiSandbox appliance or cloud service. This is correct because the FortiGate acts as a filtering gateway, checking the license first to ensure the service is authorized, then verifying the file type against a predefined supported list—if the file type is unsupported, it is dropped immediately regardless of other settings. On the Fortinet NSE 7 Advanced Security NSE7 exam, this question tests your understanding of the FortiGate-FortiSandbox integration flow, often trapping candidates who overlook the file-type filter or assume any file can be submitted. A common memory tip is to think of the three Cs: Credentials (license), Category (file type), and Connection (network path).
NSE7 Advanced Threat Protection Practice Question
This NSE7 practice question tests your understanding of advanced threat protection. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A FortiGate administrator is troubleshooting why files are not being submitted to FortiSandbox for analysis. Which THREE conditions must be met for file submission to work? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The file type must be in FortiSandbox's supported list
Option B is correct because FortiSandbox only supports analysis for specific file types (e.g., PE, PDF, Office documents). If the file type is not in the supported list, the FortiGate will not submit it, even if all other conditions are met. This is a fundamental filtering step in the FortiGate-FortiSandbox integration.
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 file type must be in FortiSandbox's supported list
Why this is correct
Unsupported files are not submitted.

✓
The antivirus profile must be in proxy-based inspection mode
Why this is correct
Flow-based does not support file submission.

✗
The FortiSandbox must be in inline scanning mode
Why it's wrong here
Inline scanning is a mode, but file submission works in other modes too.
✓
The FortiGate must have a valid FortiSandbox license
Why this is correct
License is required for submission.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the requirement for SSL inspection (must be enabled, not disabled) and assume FortiSandbox must be in inline mode, when in fact the FortiGate's inspection mode (proxy-based) is the critical factor.
Detailed technical explanation
How to think about this question
The FortiGate uses the antivirus profile to determine which files to submit, and proxy-based inspection is required because it allows the FortiGate to buffer the entire file for scanning before forwarding. In flow-based mode, the file is streamed and cannot be held for sandbox submission. The FortiSandbox license is validated via the FortiGuard subscription service, and without it, the FortiGate will not attempt to submit files.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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.

What is the correct answer to this question?
The correct answer is: The file type must be in FortiSandbox's supported list — Option B is correct because FortiSandbox only supports analysis for specific file types (e.g., PE, PDF, Office documents). If the file type is not in the supported list, the FortiGate will not submit it, even if all other conditions are met. This is a fundamental filtering step in the FortiGate-FortiSandbox integration.

Variation 1. A network administrator has configured FortiGate to send files to FortiSandbox for analysis. However, files are not being submitted. The administrator checks the FortiGate configuration and sees that the FortiSandbox server IP is correctly entered. What is the most likely cause of the issue?
medium
✓ A.A firewall policy is blocking communication to FortiSandbox on port 514
B.The FortiSandbox is not licensed for file submission
C.The file type is not supported by FortiSandbox
D.The FortiGate antivirus profile is set to flow-based inspection
Why A: The most likely cause is that a firewall policy is blocking communication to FortiSandbox on port 514. FortiGate uses port 514 (syslog) to submit files to FortiSandbox, and if this port is blocked by an intermediate firewall or an implicit deny policy, the submission will fail even if the server IP is correctly configured. The administrator should verify that traffic to the FortiSandbox IP on UDP/TCP 514 is permitted by all relevant policies.
