This 200-201 practice question tests your understanding of security monitoring. 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 Cisco Firepower sensor is generating an alert for a known benign application. The analyst has verified it is a false positive. What is the first step to suppress this alert?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a network analysis policy exception.
A network analysis policy (NAP) exception is the correct first step because it allows you to suppress alerts for specific benign applications without affecting the overall detection posture. In Cisco Firepower, NAP exceptions are applied before intrusion rules are evaluated, so they can filter out known false positives at the preprocessor level, preventing the rule from even triggering. This is more efficient than modifying the intrusion rule itself, as it avoids disabling detection for other traffic.
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.
✓
Create a network analysis policy exception.
Why this is correct
This suppresses the alert for the specific benign traffic without affecting other detections.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the severity threshold.
Why it's wrong here
Increasing threshold may not suppress the alert if it still meets higher severity.
✗
Submit a false positive report to Talos.
Why it's wrong here
This is a long-term action, not the immediate first step.
✗
Disable the intrusion rule globally.
Why it's wrong here
Disabling globally removes detection for all traffic, which is too drastic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between preprocessor-level suppression (NAP exceptions) and rule-level suppression (disabling rules), where candidates mistakenly choose to disable the rule globally instead of creating a targeted exception.
Detailed technical explanation
How to think about this question
Under the hood, Cisco Firepower's Snort-based inspection engine processes traffic through a series of preprocessors before reaching the intrusion rules. A network analysis policy exception creates a rule in the preprocessor that matches on specific application attributes (e.g., app ID, port, or IP) and instructs the engine to skip further inspection for that flow. This is analogous to a whitelist in the preprocessor phase, ensuring that even if the application triggers a signature, the alert is never generated. In real-world scenarios, this is commonly used for internal tools like Microsoft Teams or custom business applications that generate benign traffic matching known exploit signatures.
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 200-201 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.
