SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
Your organization is implementing Microsoft Purview Data Loss Prevention (DLP) to protect credit card numbers. You need to ensure that when a user attempts to share a document containing a credit card number via email, the email is blocked and the user receives a policy tip. Which action should you configure in the DLP policy?
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
✓
Block with user notification
In Microsoft Purview DLP, the 'Block with user notification' action sends a policy tip and blocks the email. 'Block override' allows override with justification. 'Audit only' logs without blocking. 'Notify user' sends an email but does not block. Option C is correct because it blocks the email and shows a policy tip.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Notify user
Why it's wrong here
The "Notify user" action in Microsoft Purview Data Loss Prevention (DLP) is designed to alert the end-user or an administrator when a policy match occurs, typically through a policy tip or email notification. While it raises awareness about potential policy violations, this action explicitly permits the sensitive information to be shared, meaning it does not prevent the data loss incident from occurring. It serves as a warning or educational mechanism rather than an enforcement block.
- ✗
Audit only
Why it's wrong here
The "Audit only" action records the policy match in the Microsoft Purview Activity Explorer and can trigger an alert if configured, but it takes no preventative measures against the sensitive data sharing. This means the content is allowed to be transmitted without any user intervention, notification, or blocking, making it unsuitable for actively preventing data loss. This mode is primarily utilized for monitoring, policy testing, and gathering insights into data flow before implementing stricter enforcement.
- ✓
Block with user notification
Why this is correct
The "Block with user notification" action is a robust enforcement mechanism that actively prevents the sharing of sensitive information, such as blocking an email from being sent or a file from being shared. Simultaneously, it displays a policy tip to the end-user, clearly informing them why the action was blocked and providing guidance on how to comply with organizational policies or remediate the issue. This combination effectively enforces data protection while educating users on acceptable data handling practices.
- ✗
Block override
Why it's wrong here
The "Block override" action initially prevents the sharing of sensitive information, similar to a standard block. However, it presents the user with an option to bypass the block by providing a business justification, which is then logged for auditing purposes. This means that while the action is initially blocked, the sensitive data *can* still be shared if the user chooses to override the policy, which does not align with a requirement for an absolute block without an override option.
