- A
Create a URL filter to block all URLs containing 'pornography' and 'hacking'
Why wrong: URL filter is for specific URLs, not categories. This is not the recommended way to block entire categories.
- B
Enable DNS filter and block the categories there
Why wrong: DNS filter blocks by domain name, not FortiGuard categories. It's a separate feature.
- C
Apply the web filter profile to the firewall policy that governs outbound internet traffic
The profile must be applied to the relevant policy to take effect.
- D
Enable SSL deep inspection to ensure the categories can be identified
Why wrong: SSL deep inspection is needed to inspect encrypted traffic, but categories are determined by FortiGuard rating, which works on domain names regardless of encryption.
- E
Create a web filter profile and set the categories 'Pornography' and 'Hacking' to 'block'
This directly blocks the categories.
Quick Answer
The answer is to create a web filter profile and set the categories 'Pornography' and 'Hacking' to 'block'. This is correct because a FortiGate uses web filter profiles to enforce URL and content-based restrictions; by configuring the profile to block specific categories, the firewall can inspect HTTP/HTTPS requests against the FortiGuard category database and deny access accordingly. On the Fortinet NSE 4 Network Security Professional exam, this tests your understanding of how to block website categories with web filter profiles and apply them to firewall policies—a common trap is forgetting that the profile must be explicitly attached to the policy handling internet traffic, or confusing category blocking with DNS filtering. A helpful memory tip is "Profile first, policy second": always create and configure the web filter profile to block the categories, then link it to the firewall policy to enforce the block.
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.
A network administrator wants to ensure that all users are blocked from accessing websites categorized as 'Pornography' and 'Hacking' on a FortiGate. Which TWO actions should the administrator take? (Choose two.)

Correct answer & explanation
Apply the web filter profile to the firewall policy that governs outbound internet traffic
To block categories, the administrator must configure a web filter profile that blocks the desired categories and apply that profile to the firewall policy handling internet traffic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
