Correct. Auto-labeling can scan SharePoint libraries and apply sensitivity labels based on content, enforcing protection like external sharing restrictions.
- B
Microsoft Purview Data Loss Prevention (DLP) policies
Why wrong: Incorrect. DLP policies prevent unauthorized sharing but do not apply sensitivity labels; they work alongside labels but are not the primary classification tool.
- C
Microsoft Purview retention labels

MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
This MS-900 practice question tests your understanding of describe security, compliance, privacy, and trust in microsoft 365. 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.
A healthcare organization needs to automatically apply a sensitivity label to any document stored in a SharePoint document library that contains patient diagnosis codes. The label should prevent the document from being shared externally. The classification must happen after the document is saved, not during creation. Which Microsoft Purview solution should be configured?

Correct answer & explanation
Auto-labeling with sensitivity labels in Microsoft Purview
Auto-labeling with sensitivity labels in Microsoft Purview is correct because it automatically applies a sensitivity label to documents containing sensitive content (like patient diagnosis codes) after they are saved to SharePoint. This label can enforce protection actions such as preventing external sharing, meeting the requirement for post-save classification.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing auto-labeling (which applies labels after save) with manual or default labeling (which applies during creation), or mistaking DLP policies for labeling solutions when DLP only detects and blocks sharing without applying persistent labels.
Detailed technical explanation
How to think about this question
Auto-labeling uses content scanning via Microsoft 365 built-in sensitive info types (e.g., ICD-9-CM codes) or custom regex patterns, and applies the label at rest after the document is saved. The label's encryption and rights management (Azure Information Protection) enforce the external sharing block, and the policy can be scoped to specific SharePoint sites or libraries using a policy location filter.
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.
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.
