This 200-201 practice question tests your understanding of security monitoring. 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 TWO of the following are best practices when configuring a SIEM for security monitoring?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Tune rules to reduce false positives.
Tuning SIEM rules to reduce false positives is a best practice because it improves the signal-to-noise ratio, ensuring that security analysts focus on genuine threats rather than being overwhelmed by irrelevant alerts. By adjusting thresholds, whitelisting known benign activity, or refining correlation logic, the SIEM becomes more efficient and reduces alert fatigue, which is critical for effective security monitoring.
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.
✓
Tune rules to reduce false positives.
Why this is correct
Tuning improves alert accuracy and reduces noise.
Clue confirmation
The clue word "best" in the question point toward this answer.

✗
Disable logging for low-security systems.
Why it's wrong here
Disabling logging reduces visibility and may miss attacks on those systems.
✓
Prioritize alerts based on risk.
Why this is correct
Risk-based prioritization ensures critical alerts are addressed first.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use the same log source for all event types.
Why it's wrong here
Different event types may require different log sources.
✗
Enable all default correlation rules.
Why it's wrong here
Default rules may generate excessive false positives without tuning.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that more logging or more rules always equals better security, when in fact untuned defaults and excessive logging degrade monitoring effectiveness and increase operational burden.
Detailed technical explanation
How to think about this question
SIEM correlation rules often rely on event frequency, time windows, and sequence matching (e.g., 5 failed logins in 60 seconds from the same IP). Tuning involves adjusting these parameters—such as increasing the threshold for brute-force detection in a high-traffic environment—or adding exclusion filters for known administrative accounts. In a real-world scenario, failing to tune could cause a SIEM to miss a slow, low-and-slow attack because the default rule only triggers on rapid bursts, or it could flood analysts with alerts from routine scans, leading to missed critical incidents.
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.
