Sample Question

A company wants to protect sensitive Microsoft 365 documents by automatically classifying content and applying encryption, access restrictions, and visual markings such as headers, footers, and watermarks.

Which Microsoft solution should the company use?

A. Microsoft Defender for Endpoint

B. Microsoft Sentinel

C. Microsoft Purview Sensitivity Labels

D. Microsoft Entra Conditional Access

Correct Answer

C. Microsoft Purview Sensitivity Labels

Why?

Microsoft Purview Sensitivity Labels enable organizations to classify and protect documents and emails by applying encryption, access restrictions, visual markings (such as headers, footers, and watermarks), and other protection settings. Labels can be applied manually by users or automatically based on the content of files and emails, helping organizations secure sensitive information throughout its lifecycle while supporting compliance requirements.

Detailed Explanation — Every Option

A. Microsoft Defender for Endpoint

Why this is incorrect:

Microsoft Defender for Endpoint is an endpoint security solution that protects devices from cyber threats such as malware, ransomware, phishing attacks, and other advanced attacks. It provides capabilities including endpoint detection and response (EDR), vulnerability management, and threat investigation.

While it helps secure the devices that access documents, it does not classify Microsoft 365 files or apply encryption, access restrictions, or document markings.

Exam Tip:
If the question focuses on protecting devices, think Microsoft Defender for Endpoint. If it focuses on protecting documents or emails, think Microsoft Purview.

B. Microsoft Sentinel

Why this is incorrect:

Microsoft Sentinel is Microsoft's cloud-native Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) solution. It collects and analyzes security data from multiple sources to detect threats, investigate incidents, and automate security responses.

Sentinel monitors security events—it does not classify documents or apply protection such as encryption or sensitivity labels.

Exam Tip:
Sentinel is designed for security operations and threat detection, not information protection.

C. Microsoft Purview Sensitivity Labels

Why this is correct:

Microsoft Purview Sensitivity Labels are specifically designed to classify and protect sensitive information.

They can:

• Classify documents and emails

• Apply encryption

• Restrict access

• Add headers and footers

• Apply watermarks

• Support automatic labeling

• Integrate with Microsoft 365 applications

• Help organizations meet regulatory and compliance requirements

Whenever the exam mentions protecting documents, emails, or sensitive information, Sensitivity Labels are often the correct solution.

D. Microsoft Entra Conditional Access

Why this is incorrect:

Microsoft Entra Conditional Access evaluates user and device conditions during authentication to determine whether access should be granted. Policies can require multifactor authentication (MFA), compliant devices, trusted locations, or risk-based controls before allowing users to access applications.

Although Conditional Access helps protect access to Microsoft 365 services, it does not classify documents or apply encryption or visual markings to files.
