SC-900 Practice Question: Describe the capabilities of Microsoft compliance solutions
Your company is implementing data loss prevention (DLP) policies in Microsoft Purview. You need to create a policy that prevents users from sharing credit card numbers via email to external recipients. The policy should only apply to users in the Finance department. Which action should you take?
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
✓
Create a DLP policy, select the Finance user location, and add the credit card number condition
To apply a DLP policy to specific users, you select their group (e.g., Finance) as a location when creating the policy. This ensures only Finance users are affected. Option A is wrong because auto-labeling with retention labels does not enforce DLP rules. Option B is wrong because sensitivity labels classify data but do not block sharing. Option C is wrong because copying a default template may not allow precise scoping to Finance users; creating a new policy from scratch with location selection is more accurate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a retention label and apply auto-labeling for Finance
Why it's wrong here
Retention labels are designed for data lifecycle management, dictating how long data should be kept or when it should be deleted to meet regulatory or business requirements. They do not actively monitor content for sensitive information like credit card numbers in real-time to prevent unauthorized sharing or exfiltration. Therefore, using a retention label would not address the immediate need for data loss prevention.
- ✗
Create a sensitivity label and publish it to Finance users
Why it's wrong here
Sensitivity labels classify data and can apply visual markings, encryption, or access restrictions to the content itself. While they help protect data, they do not inherently provide the real-time content inspection and enforcement capabilities required to detect and block the sharing of specific sensitive information, such as credit card numbers, based on content analysis. A separate DLP policy is needed for such proactive prevention.
- ✗
Copy the default DLP template for financial data and modify it
Why it's wrong here
Copying a default DLP template for financial data might introduce unnecessary conditions or actions not relevant to the specific requirement of preventing credit card number sharing within the Finance department. Starting a new policy from scratch allows for precise configuration, ensuring only the necessary sensitive information types, locations, and actions are included, thereby reducing complexity and potential for unintended policy enforcement.
- ✓
Create a DLP policy, select the Finance user location, and add the credit card number condition
Why this is correct
Creating a new Data Loss Prevention (DLP) policy is the direct and most effective method for preventing the unauthorized sharing of sensitive data. By selecting the Finance user location, the policy is precisely scoped to the relevant individuals, and adding the credit card number condition ensures that the policy specifically targets and enforces actions against this critical sensitive information type, directly addressing the company's objective.
