Accepted Answer

Retention labels with an auto-apply policy. Retention labels with an auto-apply policy are the correct choice because they allow you to automatically assign a retention label to SharePoint documents based on specific conditions, such as the presence of a project code, and enforce a fixed retention period (e.g., 5 years) without any user interaction. This feature is designed for automated, policy-driven retention based on content properties or sensitive information types.

Question 2

A compliance officer needs to ensure that all outgoing emails containing a customer's credit card number are automatically encrypted before delivery. External recipients must be able to reply with the same level of encryption without a separate signing-up process. Which Microsoft Purview solution should be configured?

Accepted Answer

Office 365 Message Encryption (OME) with a DLP policy. Office 365 Message Encryption (OME) with a Data Loss Prevention (DLP) policy is the correct solution because OME provides automatic encryption for emails based on sensitive information types (e.g., credit card numbers) detected by DLP rules. It also supports the 'encrypt-only' option, which allows external recipients to reply with the same level of encryption without requiring a separate sign-up or certificate exchange, leveraging the Microsoft 365 message encryption infrastructure.

Question 3

A global company needs to ensure that only employees in the 'HR' security group can access a specific set of HR documents stored in SharePoint. If a user outside the group attempts to view or copy the content, it must be blocked. The protection must persist even if someone downloads the files and shares them externally, or if the files are saved to a personal device. Which Microsoft Purview solution should be used?

Accepted Answer

Sensitivity labels with encryption and permission settings. Sensitivity labels with encryption and permission settings are the correct solution because they allow you to apply persistent protection that travels with the file, regardless of where it is stored or shared. By configuring a sensitivity label to restrict access to only members of the 'HR' security group and enabling encryption, the protection remains intact even if the file is downloaded, saved to a personal device, or shared externally. This meets the requirement for persistent access control that blocks unauthorized viewing or copying.

Microsoft Purview Message Encryption (B) is the correct solution because it allows the organization to automatically encrypt emails based on conditions (e.g., emails from Finance containing bank account numbers) and enables external recipients to reply securely using the encrypted reply portal without requiring any sign-up or additional software. This is achieved through Azure Rights Management (Azure RMS) and the Office 365 Message Encryption (OME) portal, which provides a seamless, browser-based experience for external users.
