MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
A compliance officer wants to automatically encrypt outgoing emails containing credit card numbers and also prevent recipients from forwarding or copying the content. Which Microsoft Purview solution should be applied?
⚠ Common exam trap
It's easy for candidates to confuse DLP policies with sensitivity labels, thinking DLP alone can enforce usage restrictions like 'prevent forwarding,' when in fact DLP only detects and optionally triggers a label that provides the encryption and rights management.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Sensitivity label with encryption and rights management
Sensitivity labels with encryption and rights management (Azure Rights Management) allow you to apply persistent protection that encrypts the email and restricts actions like forwarding, copying, or printing. This meets both requirements: automatic detection of credit card numbers via auto-labeling policies and enforcement of usage restrictions through Rights Management templates (e.g., Do Not Forward).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data Loss Prevention (DLP) policy with encryption
Why it's wrong here
DLP policies can detect sensitive data and block or notify, but they cannot enforce encryption with restrictions like 'do not forward'. Encryption via DLP is limited and does not provide the granular rights management needed.
- ✓
Sensitivity label with encryption and rights management
Why this is correct
Sensitivity labels in Microsoft Purview are the correct mechanism because they support automatic application of encryption and usage restrictions such as 'Do Not Forward' or 'View-Only' through label policies. When a label is auto-applied based on sensitive content types or user actions, the associated encryption is enforced via Azure Rights Management, giving the compliance officer the required control. This native integration allows for automatic encryption of outgoing emails without requiring end-user intervention.
- ✗
Microsoft Information Bar
Why it's wrong here
'Microsoft Information Bar' is not a recognized feature or component within Microsoft Purview or any Microsoft 365 workload. It appears to be a distractor loosely referencing the Office apps' informational bar that prompts users about labels or permissions, but that UI element does not enforce encryption automatically. Since no such administrative or compliance capability exists, it cannot meet the requirement for automatic encryption of outgoing data.
- ✗
Azure Information Protection unified labeling client
Why it's wrong here
The Azure Information Protection unified labeling client is an agent installed on Windows to enable manual labeling and classification by users, not an automatic encryption policy engine. While it integrates with sensitivity labels, it requires user interaction to apply labels and does not independently enforce email encryption with rights restrictions like 'Do Not Forward' based on content conditions. Modern automatic encryption is configured natively through sensitivity label policies in the Microsoft Purview compliance portal, making the client unnecessary and insufficient for this scenario.
