Respond to security incidentsmediumMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to identify IPs with a high number of alerts, indicating a possible attack. In KQL, the `summarize` operator groups data by a specified column—here, it aggregates the SQL injection alerts by IP address and counts them using `count()`, while the `where AlertCount > 5` line filters those groups to retain only IPs that generated more than five alerts in the last seven days. This combination directly surfaces high-frequency sources, which is a core technique in alert analysis for the Microsoft Security Operations Analyst SC-200 exam, where you must distinguish between benign noise and targeted attacks. A common trap is confusing `summarize` with `distinct`—remember that `summarize` creates new aggregated rows, not just deduplication. For the exam, think of it as “group and filter” rather than “remove duplicates.” A quick memory tip: “Summarize to cluster, where to filter the cluster.”

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.

Exhibit

Refer to the exhibit.

```kusto
SecurityAlert
| where TimeGenerated > ago(7d)
| where AlertName == "Malicious SQL injection"
| extend IPAddress = tostring(parse_json(Entities)[0].Address)
| summarize AlertCount = count() by IPAddress
| where AlertCount > 5
| project IPAddress, AlertCount
```

You are investigating repeated SQL injection alerts. The KQL query returns IP addresses with more than 5 alerts in the last 7 days. What is the purpose of the `summarize` and `where AlertCount > 5` lines?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

To identify IPs with a high number of alerts, indicating a possible attack.

Option D is correct because the query groups alerts by IP and filters for those with high frequency, indicating a potential attack. Option A is wrong because the query does not remove duplicates. Option B is wrong because it does not count distinct IPs. Option C is wrong because it does not correlate with other tables.

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.

  • To identify IPs with a high number of alerts, indicating a possible attack.

    Why this is correct

    High alert counts may indicate ongoing malicious activity.

    Related concept

    Read the scenario before looking for a memorised answer.

  • To correlate alerts with other data sources.

    Why it's wrong here

    The query only uses SecurityAlert.

  • To remove duplicate alerts from the same IP.

    Why it's wrong here

    It counts alerts, not removes duplicates.

  • To count the number of distinct IP addresses.

    Why it's wrong here

    It counts alerts per IP, not distinct IPs.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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.
