SC-200 Respond to security incidents Practice Question

This SC-200 practice question tests your understanding of respond to security incidents. 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.

Your organization uses Microsoft Sentinel. You have a scheduled analytics rule that queries Windows Security Events to detect local admin group modifications. The rule runs every hour and looks back 1 hour. However, you are missing events that occur within the first few minutes of the hour. 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: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
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.

A
The event time is in local time, and the query uses UTC, causing events near the boundary to be excluded.
Time zone mismatch can cause events to fall outside the query window.
B
The query period is too short; it should be 2 hours.
Why wrong: A 1-hour lookback should capture events within that hour.
C
The rule is using 'Last activity' instead of 'TimeGenerated'.
Why wrong: Using 'TimeGenerated' is standard; the issue is time zone.
D
There is a 5-minute ingestion delay for Windows events.
Why wrong: Ingestion delay is typically seconds, not minutes.

Why each option matters

Correct answer & explanation

✓

The event time is in local time, and the query uses UTC, causing events near the boundary to be excluded.

The scheduled analytics rule uses a lookback period of 1 hour, but if the event time is stored in local time while the query uses UTC, events near the hour boundary can be excluded due to time zone offset. Microsoft Sentinel stores events in UTC by default, and the query's time filter (e.g., 'TimeGenerated > ago(1h)') compares against UTC timestamps. If the Windows Security Events are logged in local time and not converted, events occurring just after the hour in local time may fall outside the UTC lookback window, causing them to be missed.

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

The trap here is that candidates often assume ingestion delay or query period length is the cause, but the real issue is time zone mismatch between event timestamps and the query's UTC-based lookback window.

Detailed technical explanation

How to think about this question

Microsoft Sentinel's scheduled analytics rules use the 'TimeGenerated' field (in UTC) for query time filtering. When Windows events are collected via the Log Analytics agent or AMA, the 'TimeGenerated' is set at ingestion time, but the original event timestamp (e.g., EventLog/EventData/TimeCreated) may be in local time. If the KQL query uses 'TimeGenerated' but the event's original timestamp is in local time, events near the hour boundary can be misaligned. A common mitigation is to use the 'TimeCreated' field with explicit time zone conversion (e.g., 'datetime_add('hour', -5, TimeCreated)' for EST) or ensure the agent sends events in UTC.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
