Question 1

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?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

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).

Question 2

An organization wants to prevent employees from sharing sensitive files with external users via SharePoint Online, but they need to allow sharing with a specific external partner for a single project. What is the most efficient configuration?

Accepted Answer

Disable external sharing at the tenant level and enable it only for the specific project site. It allows the organization to disable external sharing globally at the tenant level via the SharePoint admin center, which prevents all users from sharing with external users by default. Then, by enabling external sharing only for the specific project site (site-level override), the organization can grant the necessary access to the external partner while maintaining the broad restriction. This is the most efficient approach because it uses a single configuration change at the tenant level and a targeted exception at the site level, avoiding complex policies or labels.

Answer

Change the default sharing link type to 'Specific people' and add the partner's domain to an allow list

Answer

Apply sensitivity labels with encryption to all files

Answer

Configure a DLP policy to block external sharing except for the partner domain

Question 3

A compliance officer needs to set up a policy that automatically monitors and detects activities related to accessing sensitive data from outside the corporate network. When a user from a foreign country accesses a confidential file, the policy should trigger an alert and require additional authentication. Which combination of Microsoft 365 solutions achieves this?

Accepted Answer

Microsoft Purview Data Loss Prevention and Conditional Access. Microsoft Purview Data Loss Prevention (DLP) monitors and detects sensitive data access from outside the corporate network, while Conditional Access enforces additional authentication (e.g., MFA) when such access is detected. Together, they meet the requirement for automatic alerting and step-up authentication based on location and data sensitivity.

Question 8

A compliance administrator needs to ensure that any document containing a patient's health information (e.g., medical record number) is automatically encrypted and restricted to authorized users. The encryption should be enforced regardless of where the document is saved (SharePoint, OneDrive, or email). Which Microsoft Purview feature should they configure?

Accepted Answer

Auto-labeling policies with sensitivity labels. Auto-labeling policies with sensitivity labels are the correct choice because they can automatically apply encryption and access restrictions to documents containing sensitive data like medical record numbers, regardless of where the document is saved (SharePoint, OneDrive, or email). Sensitivity labels support persistent protection that travels with the file, enforcing encryption and authorized user restrictions even when the file is moved or copied. This meets the requirement for automatic, location-independent encryption and access control.

Question 9

A compliance administrator needs to automatically detect when employees share documents containing a customer's credit card number via email and block such sharing before the email is sent. Which Microsoft Purview solution should they configure?

Accepted Answer

Data Loss Prevention (DLP). Data Loss Prevention (DLP) is the correct solution because it is specifically designed to automatically detect sensitive data, such as credit card numbers, in transit (e.g., email) and enforce policy actions like blocking the email before it is sent. DLP uses deep content analysis, including pattern matching against predefined sensitive information types (e.g., credit card number regex), to inspect email bodies and attachments in real time within Exchange Online.

Additionally, editing and printing of these documents must be disabled. Which combination of Microsoft Purview features should be used?

Accepted Answer

Sensitivity labels with auto-labeling and encryption that restricts permissions to the 'Data Privacy' group. Sensitivity labels in Microsoft Purview can be configured with auto-labeling to automatically detect and classify documents containing PII, and then apply encryption that restricts access to only the 'Data Privacy' security group. Additionally, the label can enforce usage rights such as 'View Only' to disable editing and printing, meeting all requirements.

Question 11

A legal team is preparing for litigation. They need to place a hold on all content (emails, documents, Teams messages) related to a specific project across the entire organization. The hold must prevent any deletion or modification of the content. Which Microsoft Purview solution should they use?

Accepted Answer

eDiscovery (Premium) with legal hold. EDiscovery (Premium) with legal hold is the Microsoft Purview solution specifically designed to preserve content in-place for litigation. When a legal hold is applied to a case, it prevents deletion or modification of emails, documents, and Teams messages across the entire organization by placing a hold on the underlying Exchange Online mailboxes, SharePoint sites, and OneDrive accounts. This ensures that all content related to the project is immutable for the duration of the hold, meeting the legal team's requirement.

Question 12

A compliance officer needs to automatically detect when an employee attempts to send an email containing a social security number (SSN) to an external recipient. The solution should block the email from being sent and notify the employee with a policy tip. Which Microsoft Purview solution should be configured?

Accepted Answer

Microsoft Purview Data Loss Prevention (DLP). Microsoft Purview Data Loss Prevention (DLP) is the correct solution because it is specifically designed to detect sensitive information (such as social security numbers) in emails and other data in transit. When a DLP policy is configured with a rule that matches the SSN condition and an action to block the message, it automatically prevents the email from being sent and displays a policy tip to the user, notifying them of the violation. This aligns directly with the requirement to both block the email and provide real-time user notification.

Question 13

A compliance officer needs to ensure that any document containing passport numbers automatically gets a 'Highly Confidential' label and is encrypted when saved in SharePoint. The labeling should occur without any user interaction. Which Microsoft Purview feature should they configure?

Accepted Answer

Auto-labeling policy for sensitivity labels. Auto-labeling policies in Microsoft Purview can automatically apply a sensitivity label (e.g., 'Highly Confidential') to documents containing passport numbers when saved in SharePoint, without any user interaction. This is achieved by configuring a policy that uses sensitive info types (e.g., 'Passport Number') to detect the data and then automatically apply the label and encryption. The labeling occurs at rest, triggered by document upload or modification, meeting the compliance officer's requirement for zero user intervention.
