- A
Set the FortiGuard category to 'Monitor' and create a URL filter to block all other sites
Why wrong: This would require maintaining a large block list, which is impractical.
- B
Add a URL filter entry with the site's domain set to 'Allow'
URL filter entries are processed before FortiGuard categories. An allow entry for the specific URL will override the category block.
- C
Use the DNS filter to allow the site's FQDN
Why wrong: DNS filter controls DNS resolution, not HTTP access. It would not override a web filter category block.
- D
Add the site to the FortiGuard category override list with action 'Allow'
Why wrong: Category override allows you to change the action for a category, but you cannot create an exception for a specific URL within a category via overlay.
Quick Answer
The answer is to add a URL filter entry with the site’s domain set to ‘Allow’. This works because FortiGate processes URL filter entries in order, from top to bottom, before evaluating FortiGuard category-based blocks; an explicit ‘Allow’ entry for the specific domain will override the blocked category action for that single site. On the Fortinet NSE 4 exam, this scenario tests your understanding of the URL filter precedence hierarchy—a common trap is assuming you must change the category itself or use a different security policy, but the correct approach is to insert the allow exception within the same URL filter profile. Remember the memory tip: “Allow first, block later”—the explicit allow entry must be placed above the category block rule in the filter list to take effect.
NSE4 Security Profiles Practice Question
This NSE4 practice question tests your understanding of security profiles. 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 wants to block all traffic to websites in the 'Pornography' category but allow an exception for a specific research site that falls under that category. The FortiGuard category is set to block. How should the administrator configure the exception?
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
Add a URL filter entry with the site's domain set to 'Allow'
In FortiGate, to allow a specific site that is blocked by a category, you add a URL filter entry with the action 'Allow' above the category block. URL filter entries are evaluated first and can override the category action.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Set the FortiGuard category to 'Monitor' and create a URL filter to block all other sites
Why it's wrong here
This would require maintaining a large block list, which is impractical.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 NSE4 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.
