SC-100 Practice Question: Evaluate GRC and security operations strategies
This SC-100 practice question tests your understanding of evaluate grc and security operations strategies. 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.
A company uses Microsoft Defender for Cloud to assess the security posture of their Azure subscriptions. They want to ensure that critical recommendations are automatically remediated. They create a workflow automation that triggers a Logic App for specific recommendations. However, the Logic App fails to run. 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: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The managed identity of the Logic App lacks permissions on the target resources.
The most likely cause is that the Logic App's managed identity lacks the necessary permissions on the target Azure resources. Workflow automations in Defender for Cloud use a Logic App that executes remediation actions; if the Logic App's identity (either system-assigned or user-assigned) does not have the required RBAC role (e.g., Contributor or a custom role with specific actions) on the resource scope, the remediation run will fail with an authorization error. This is a common misconfiguration because the automation trigger itself succeeds, but the downstream action fails due to insufficient permissions.
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 managed identity of the Logic App lacks permissions on the target resources.
Why this is correct
Logic App needs permissions to perform remediation actions.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The subscription is not onboarded to Defender for Cloud.
Why it's wrong here
Workflow automation can still be configured but assessments might be limited.
✗
Defender for Cloud is disabled for the resource group.
Why it's wrong here
Defender for Cloud is enabled at the subscription level.
✗
The recommendation is disabled in the security policy.
Why it's wrong here
If disabled, the recommendation won't appear, but the automation would not trigger.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the trigger itself is failing due to a misconfiguration in Defender for Cloud, when in fact the trigger succeeds and the failure is in the Logic App's downstream action due to missing RBAC permissions on the managed identity.
Detailed technical explanation
How to think about this question
Under the hood, Defender for Cloud's workflow automation uses an Azure Resource Manager (ARM) trigger to invoke the Logic App when a recommendation's state changes. The Logic App then executes an HTTP action (e.g., PATCH or POST) against the target resource's ARM endpoint. For this to succeed, the Logic App's managed identity must have the appropriate RBAC role (e.g., 'Security Admin' or a custom role with 'Microsoft.Security/compliances/write') on the resource scope. A subtle behavior is that the trigger itself does not validate permissions—it only fires the Logic App, so the failure occurs silently during the remediation step, often logged as a 403 Forbidden in the Logic App run history.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
