The correct answer is that the rule blocks access to content containing a credit card number in Exchange and SharePoint, without user notification. This is because the JSON rule uses the 'BlockAccess' action, which prevents users from opening or interacting with the detected sensitive data, and critically, the rule lacks any 'NotifyUser' or 'NotifyUserOverride' parameter, meaning no policy tip or email notification is sent to the end user. On the SC-900 exam, this scenario tests your understanding of how DLP actions and notifications are configured separately—a common trap is assuming that blocking access automatically includes a notification, but they are distinct settings. Remember the memory tip: "Block without a knock" means the door is locked, but no one tells you why.

✓
Blocks access to content containing a credit card number in Exchange and SharePoint, without user notification.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
