Question 660 of 969

Quick Answer

The answer is that the action type must be set to 'LogicApp' instead of 'EventHub'. This is because a Microsoft Sentinel playbook is built on Azure Logic Apps, and Defender for Cloud automation can only trigger a playbook by sending an HTTP POST request to the playbook’s trigger URL—an action that requires the 'LogicApp' type. The 'EventHub' type, as shown in the exhibit, would forward the alert to an event hub, which cannot directly invoke a Sentinel playbook. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of the integration between Defender for Cloud and Sentinel, specifically how automation rules bridge the two services. A common trap is assuming any action type can trigger a playbook, but only LogicApp works for this purpose. Remember: to run a playbook, you need a Logic App trigger, not an Event Hub stream.

SC-100 Practice Question: Design security operations, identity, and compliance capabilities

This SC-100 practice question tests your understanding of design security operations, identity, and compliance capabilities. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.

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

The action type should be 'LogicApp' instead of 'EventHub'

Option B is correct because the exhibit shows the automation sends to EventHub, but to trigger a Sentinel playbook, the action type should be 'LogicApp' with the playbook's trigger URL. Option A is wrong because the source is already set to Assessments. Option C is wrong because the severity filter is correctly set to High. Option D is wrong because the API version is not the issue; the action type is wrong.

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.

  • The severity filter should be 'Low' to capture all assessments

    Why it's wrong here

    The requirement is for high-severity, so the filter is correct.

  • The action type should be 'LogicApp' instead of 'EventHub'

    Why this is correct

    To invoke a playbook in Sentinel, the automation action must be of type 'LogicApp' with the playbook's callback URL.

    Related concept

    Read the scenario before looking for a memorised answer.

  • The eventSource should be 'Alerts' instead of 'Assessments'

    Why it's wrong here

    The eventSource 'Assessments' is correct for security assessments; changing to 'Alerts' would not trigger on assessments.

  • The API version should be '2020-01-01'

    Why it's wrong here

    The API version is not the issue; the action type mismatch is the problem.

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.

Same concept, more angles

1 more ways this is tested on SC-100

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. Refer to the exhibit. You have deployed the automation shown in the exhibit in Microsoft Defender for Cloud. The automation triggers a Logic App when a high-severity alert is generated. Users report that the Logic App is not being triggered for some high-severity alerts. What is the most likely cause?

hard
  • A.The trigger condition uses 'Equals' instead of 'Contains' for severity.
  • B.The Logic App resource ID is incorrect.
  • C.Some high-severity alerts are generated from a different event source not included in the 'sources' array.
  • D.The automation is configured to trigger on 'Alerts' but should be 'SecurityPolicies'.

Why C: Option B is correct because the automation is configured to trigger on 'Alerts' source, but Defender for Cloud also generates 'RegulatoryComplianceAssessment' and other sources. Some high-severity alerts may come from a different event source that is not included. Option A is incorrect because the event source is 'Alerts', not 'SecurityPolicies'. Option C is incorrect because severity value is correct. Option D is incorrect because the trigger condition is correct.
