SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
You need to ensure that sensitive documents in Microsoft SharePoint Online are automatically classified and protected when they contain credit card numbers. What should you configure?
⚠ Common exam trap
Many exam-takers confuse DLP policies with auto-labeling, but DLP policies only monitor and block data sharing, whereas auto-labeling with sensitivity labels actually classifies and protects the content itself.

Correct answer & explanation
✓
A sensitivity label with auto-labeling for Microsoft Purview Information Protection
A sensitivity label with auto-labeling for Microsoft Purview Information Protection is correct because it can automatically classify and protect documents based on sensitive content, such as credit card numbers, using built-in sensitive information types. This ensures that when a document in SharePoint Online contains credit card data, it is automatically labeled with encryption and usage restrictions without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A sensitivity label with auto-labeling for Microsoft Purview Information Protection
Why this is correct
Sensitivity labels with auto-labeling are specifically designed within Microsoft Purview Information Protection to automatically classify and apply protective measures to documents. They leverage sensitive information types and trainable classifiers to identify content, then enforce encryption, visual markings, and access restrictions, ensuring proactive data protection from creation and throughout its lifecycle.
- ✗
A retention policy for SharePoint
Why it's wrong here
A retention policy for SharePoint governs the lifecycle of content by defining how long documents should be kept or when they should be deleted. While crucial for compliance and data governance, these policies do not perform automatic content classification or apply protective measures like encryption or access controls to sensitive information within the documents themselves.
- ✗
A data loss prevention (DLP) policy
Why it's wrong here
A data loss prevention (DLP) policy primarily focuses on identifying, monitoring, and protecting sensitive information across various locations and preventing its inappropriate sharing or transfer. While DLP can detect sensitive data, it acts reactively to block actions or notify users, rather than proactively classifying documents and applying persistent protection like encryption directly to the file content.
- ✗
A retention label for regulatory compliance
Why it's wrong here
A retention label is applied to content to manage its retention and disposition based on regulatory, legal, or business requirements, ensuring data is kept for the correct duration. Unlike sensitivity labels, retention labels do not classify content based on its sensitivity, nor do they apply encryption, visual markings, or access restrictions to protect the information within the document.
