SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. 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 actions should you take to reduce the cost of Microsoft Sentinel while maintaining security coverage?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Reduce the retention period of tables that do not require long-term storage.
Option B is correct because reducing the retention period for tables that do not require long-term storage directly lowers the data storage costs in Microsoft Sentinel. Sentinel charges per GB of data stored, and by shortening retention (e.g., from 90 days to 30 days) for non-critical tables, you reduce the volume of data retained without affecting security monitoring or incident investigation for the shortened period.
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.
✗
Remove data connectors for non-critical sources.
Why it's wrong here
Removing connectors may miss important threats.
✓
Reduce the retention period of tables that do not require long-term storage.
Why this is correct
Shorter retention reduces storage costs.

✓
Ingest verbose logs (e.g., DNS events) into Basic Logs tier.
Why this is correct
Basic Logs is cheaper for high-volume, low-analytics data.

✗
Disable analytics rules that generate low-severity incidents.
Why it's wrong here
Disabling rules reduces detection coverage.
✗
Switch the workspace pricing tier from Capacity Reservations to Pay-as-you-Go.
Why it's wrong here
Pay-as-you-go is typically more expensive for high volume.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse reducing data ingestion (Option A) with reducing storage costs, but the question explicitly requires maintaining security coverage, so removing data connectors would break that requirement.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Sentinel uses Log Analytics workspaces where each table has a configurable retention period (default 30-730 days). Reducing retention for tables like 'Heartbeat' or 'Perf' (performance logs) that are not security-relevant can significantly cut costs, as Sentinel bills for both ingestion and retention. In a real-world scenario, a SOC might keep security event tables (e.g., SecurityEvent, CommonSecurityLog) for 90 days for compliance, but reduce 'Usage' or 'AzureActivity' tables to 30 days to save money while still maintaining full security coverage.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
