The answer is to create an auto-labeling policy for retention labels targeting sensitive info types. This is correct because Microsoft Purview’s auto-labeling policies can automatically scan SharePoint Online documents for patterns like credit card numbers, which are defined as a sensitive info type, and then apply a retention label without requiring user intervention. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of how to integrate data classification with retention governance, often appearing as a distractor where candidates mistakenly choose manual labeling or DLP policies instead. A common trap is confusing auto-labeling with data loss prevention policies—remember that DLP blocks or alerts, while auto-labeling applies labels. Memory tip: think “auto-label for auto-retention” to link the policy type directly to the retention outcome.
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.
Your company uses Microsoft Purview to protect sensitive data. You need to automatically apply a retention label to documents containing credit card numbers detected in SharePoint Online. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an auto-labeling policy for retention labels targeting sensitive info types.
Option D is correct because auto-labeling policies in Microsoft Purview can automatically apply retention labels to documents based on sensitive info types, such as credit card numbers. This allows you to enforce retention rules without manual intervention, directly targeting the detected sensitive data in SharePoint Online.
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.
✗
Configure a Data Loss Prevention (DLP) policy to apply the label.
Why it's wrong here
DLP policies do not apply retention labels.
✗
Create a sensitivity label with auto-labeling for SharePoint.
Why it's wrong here
Sensitivity labels are for classification, not retention.
✗
Use a trainable classifier to detect credit card numbers and apply the label.
Why it's wrong here
Trainable classifiers are more complex and not the simplest solution.
✓
Create an auto-labeling policy for retention labels targeting sensitive info types.
Why this is correct
Auto-labeling policies can automatically apply retention labels based on sensitive info types.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse retention labels with sensitivity labels, or assume DLP policies can apply retention labels directly, when in fact DLP applies sensitivity labels and auto-labeling policies are the correct mechanism for retention labels.
Detailed technical explanation
How to think about this question
Auto-labeling policies for retention labels use the same sensitive info types (e.g., Credit Card Number) as DLP, but they operate asynchronously on content at rest, scanning SharePoint Online libraries and applying the specified retention label. This is distinct from manual labeling or default labels, and the policy can be scoped to specific locations or conditions, ensuring compliance with data retention regulations without impacting user workflows.

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.
