SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
A user reports that they cannot access a sensitive document in SharePoint Online. The document has a 'Highly Confidential' sensitivity label. You verify the label is applied correctly. What is the most likely reason for the access issue?
⚠ Common exam trap
Watch out — candidates often confuse DLP policies with sensitivity label encryption, assuming DLP blocks access to labeled documents, when in fact DLP only monitors and controls sharing actions, not read access to already-stored content.

Correct answer & explanation
✓
The label's encryption settings restrict access to specific users
The 'Highly Confidential' sensitivity label is configured with encryption that restricts access to specific users or groups. Since you verified the label is applied correctly, the most likely reason the user cannot access the document is that their account is not included in the encryption permissions defined by the label. Sensitivity labels in Microsoft Purview Information Protection use Azure Rights Management (Azure RMS) to enforce encryption, and only authorized users with the appropriate rights can decrypt and access the content.
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 label's encryption settings restrict access to specific users
Why this is correct
Sensitivity labels, when configured with encryption, apply rights management protection to documents. This protection can explicitly define which users or groups have specific access rights, such as view-only, edit, or full control. If a user reports being unable to access a sensitive document, it is highly probable that the label's encryption settings have been configured to restrict access to a specific set of authorized individuals, and the reporting user is not included in that authorized list. This is a fundamental capability of Microsoft Purview Information Protection.
- ✗
The sensitivity label is missing
Why it's wrong here
If the sensitivity label were missing from the document, it would imply that no specific information protection policies, including encryption or access restrictions, have been applied by a label. In such a scenario, the document would typically be accessible based on standard SharePoint or OneDrive permissions, rather than being explicitly blocked by a label. The problem statement implies a restriction is in place, and the existing context confirms the label is applied, making its absence an incorrect diagnosis.
- ✗
A DLP policy is blocking access
Why it's wrong here
Data Loss Prevention (DLP) policies are primarily designed to prevent sensitive information from being inappropriately shared, moved, or exfiltrated outside defined organizational boundaries. While DLP can block actions like sharing a document with external users or copying content to unmanaged devices, it does not typically block an authorized user's direct access to a document within the organization's internal systems. DLP focuses on data egress and inappropriate sharing, not on restricting internal access to a document itself.
- ✗
A retention policy is blocking access
Why it's wrong here
Retention policies are established to manage the lifecycle of content, ensuring its preservation for compliance or regulatory requirements, or its deletion after a specified period. These policies govern how long content is kept and when it can be disposed of, but they do not inherently restrict a user's ability to open, view, or edit a document. A retention policy's function is about data lifecycle management, not about controlling real-time access permissions to a file.
