The answer is adding the destination IP address to the 'SSL Exempt IPs' list within the SSL/SSH inspection profile, along with using the 'SSL Exempt Domains' list and configuring a firewall policy to bypass inspection. These methods allow you to exclude HTTPS traffic from SSL inspection by specifying trusted destinations or domains that FortiGate will skip decrypting, matching the SNI field or certificate CN/SAN to reduce overhead. On the Fortinet NSE 4 Network Security Professional NSE4 exam, this topic tests your understanding of how to balance security with performance by selectively exempting traffic, often appearing in scenario-based questions where you must choose the correct exemption method. A common trap is confusing the 'SSL Exempt IPs' list with certificate inspection profiles—remember that IPs and domains are exempted in the SSL/SSH profile itself, not in firewall policies. Memory tip: "Exempt by IP, domain, or policy—three ways to skip the decrypt key."
NSE4 Security Profiles Practice Question
This NSE4 practice question tests your understanding of security profiles. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which THREE of the following are valid methods to exclude certain HTTPS traffic from SSL inspection on a FortiGate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Adding the domain to the 'SSL Exempt Domains' list in the SSL/SSH inspection profile.
Option A is correct because the 'SSL Exempt Domains' list in the SSL/SSH inspection profile allows you to specify domain names (e.g., *.example.com) that will bypass SSL inspection entirely. When FortiGate matches the SNI field in the ClientHello or the certificate CN/SAN against this list, it skips decryption and passes the traffic through without inspection, reducing overhead for trusted or non-critical domains.
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.
✓
Adding the domain to the 'SSL Exempt Domains' list in the SSL/SSH inspection profile.
Why this is correct
Domain-based exemption is a supported method.
Related concept

✗
Setting the firewall policy action to 'accept' with no inspection.
Why it's wrong here
This would apply to all traffic in the policy, not as a selective exemption.
✓
Using a certificate category exemption (e.g., exempting 'Fortinet Trusted Certificate').
Why this is correct
Certificate category exemption is a supported method.
Related concept

✗
Using a web filter category exemption.
Why it's wrong here
Web filter categories do not exempt from SSL inspection.
✓
Adding the destination IP address to the 'SSL Exempt IPs' list in the SSL/SSH inspection profile.
Why this is correct
IP-based exemption is a supported method.
Related concept

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse web filter category exemptions with SSL inspection exemptions, but web filter exemptions only affect URL filtering decisions, not the decryption process itself.
Detailed technical explanation
How to think about this question
Under the hood, FortiGate's SSL inspection uses the SNI extension from the TLS ClientHello to match exempt domains before any decryption occurs. For IP-based exemptions, the FortiGate checks the destination IP against the 'SSL Exempt IPs' list, which is useful for traffic where SNI is not present (e.g., legacy applications). In real-world scenarios, exempting high-latency or sensitive services (like banking or healthcare portals) prevents certificate pinning failures and reduces processing load on the FortiGate.

→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

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

Variation 1. A FortiGate is configured for SSL deep inspection using a CA certificate. Users report that some websites show certificate errors. The administrator wants to allow these sites without inspection. Which setting should be used?
medium
A.Disable certificate validation in the SSL inspection profile
B.Create a separate firewall policy without SSL inspection
C.Set the action for invalid certificates to 'allow'
✓ D.Add the websites to the SSL/SSH exemption list
Why D: Option D is correct: SSL/SSH exemption list allows specific destinations to bypass deep inspection, while still applying other security profiles.
