The answer is the web filter profile has an override configured for those users. This is correct because the override feature in Fortinet’s web filtering allows specific users or groups to bypass the rating system temporarily, meaning even when the rating engine returns “rating not allow” for a blocked category, the override grants access regardless. On the Fortinet NSE 4 Network Security Professional exam, this scenario tests your understanding of how overrides interact with web filter profiles and the debug output—a common trap is mistaking this for a broken rating server or incorrect policy order. Remember that “rating not allow” indicates the category is blocked by the rating engine, but if users still get through, an override is the likely culprit. Memory tip: Override = Override the rating, not the policy.
NSE4 Security Profiles Practice Question
This NSE4 practice question tests your understanding of security profiles. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 notices that some users can access blocked web categories despite a web filter profile applied to the policy. The admin runs 'diagnose debug rating' and sees 'rating not allow' for the category. 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 web filter profile has an 'override' configured for those users
Option B is correct because the override feature can be used to grant users temporary access to blocked categories, bypassing the web filter rating.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
The web filter profile has an 'override' configured for those users
Why this is correct
An override allows users to bypass the web filter rating. Even if the rating is 'block', the override permits access.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The policy is not using the correct web filter profile
Why it's wrong here
If the wrong profile is applied, the rating might not match, but 'rating not allow' suggests the profile is evaluating correctly.
✗
DNS filter is allowing the domain
Why it's wrong here
DNS filter is separate; web filter rating still applies regardless of DNS filter status.
✗
The FortiGuard web filter database is outdated
Why it's wrong here
An outdated database might show 'rating not allow' but the symptom is that users can access blocked sites, which contradicts the rating.

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.

Variation 1. A network administrator notices that users can access websites categorized as 'Pornography' despite a web filter profile blocking that category. The firewall policy uses the web filter profile and is applied to the users' traffic. What is the MOST likely cause?
medium
✓ A.The FortiGate cannot reach the FortiGuard servers
B.The web filter profile is applied to the wrong policy
C.The users are bypassing the FortiGate using a proxy
D.The web filter profile has the 'Override' feature enabled
Why A: Option C is correct because if the FortiGate cannot reach the FortiGuard servers, web filtering will fail open by default, allowing all web traffic. The administrator should verify FortiGuard connectivity.
