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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Refer to the exhibit. You are reviewing a Microsoft Defender for Cloud automation resource. You want the automation to trigger a playbook in Microsoft Sentinel when a high-severity security assessment is found. Based on the exhibit, what is the missing configuration?
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 Microsoft Defender for Cloud automation can trigger a playbook in Microsoft Sentinel only by using a LogicApp action. The exhibit shows an EventHub action type, which is used for streaming events to an event hub, not for invoking a playbook. To trigger a Sentinel playbook from a Defender for Cloud assessment, the action type must be set to 'LogicApp' and configured with the playbook's trigger URL.
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
The trap here is that candidates may focus on the severity filter or event source, overlooking that the action type must be specifically 'LogicApp' to invoke a playbook, as 'EventHub' is a valid action but for a different purpose.
Detailed technical explanation
How to think about this question
Under the hood, Defender for Cloud automation uses Azure Resource Manager templates to define triggers and actions. The 'LogicApp' action type requires a callback URL from the Sentinel playbook, which is an HTTP-triggered Logic App. The EventHub action type is designed for forwarding raw assessment data to an event hub for external processing, not for invoking Sentinel playbooks. This distinction is critical because the playbook must be triggered synchronously to process the assessment and potentially create an incident or take remediation steps.

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.
