In Microsoft Teams:

Files shared in 1:1 or group chats

These files are stored in the sender’s OneDrive for Business.

So, to protect them with DLP and prevent guest access, the relevant location is OneDrive accounts.

Files shared in Teams channels

These files are stored in the underlying SharePoint Online site associated with that Team.

So, to protect them with DLP and prevent guest access, the relevant location is SharePoint sites.

Incorrect options:

Exchange email: Protects email messages, not Teams-shared files.

Teams chat and channel messages: Protects text messages, not the attached or shared files.

Comprehensive Detailed Explanation with References

When multiple advanced DLP rules match content, Microsoft 365 DLP evaluates based on:

Rule priority

Lower number = higher priority (0 highest).

Among Rule2 (priority 1), Rule3 (priority 2), and Rule4 (priority 3), Rule2 has the highest priority.

Conflict resolution (single vs multiple rules applied)

By default, only the highest-priority rule applies if multiple rules match. → That’s why in the first dropdown, the correct answer is Only Rule2 takes effect.

However, you can configure advanced DLP to allow multiple matching rules to take effect simultaneously. If this setting is enabled, then Rule2, Rule3, and Rule4 all apply. → That’s why in the second dropdown, the correct answer is Rule2, Rule3, and Rule4 take effect.

To create custom trainable classifiers in Microsoft Purview, the user must have rights in the compliance portal. The Compliance Administrator role provides the necessary permissions to create and manage trainable classifiers. Security roles focus on threat management, and Global Administrator is excessive (not least privilege).

Step 1 – Scenario

Endpoint Data Loss Prevention (Endpoint DLP) is implemented in Microsoft 365.

Computers: Windows 11, joined to Microsoft Entra (Azure AD), with Microsoft 365 Apps installed.

Goal: Ensure Endpoint DLP policies can protect local content on these devices.

Step 2 – How Endpoint DLP works

Endpoint DLP builds on the same policy framework as Microsoft Purview DLP, but specifically extends coverage to Windows 10/11 devices.

Requirements:

Devices must be onboarded to Microsoft Purview (via Microsoft Defender for Endpoint or via Purview device onboarding).

Endpoint DLP does not require the Microsoft Purview Information Protection (MIP) client.

The MIP client is only required for sensitivity labeling and AIP functionality, not for Endpoint DLP.

Step 3 – Why the proposed solution is incorrect

Deploying the Microsoft Purview Information Protection client does not enable Endpoint DLP.

Endpoint DLP requires device onboarding into Microsoft Purview compliance.

Therefore, this solution does not meet the goal.

Step 4 – Microsoft Reference

Microsoft Docs states:

“To use Endpoint data loss prevention (Endpoint DLP), devices must be onboarded to the Microsoft Purview compliance portal. Installing the Microsoft Information Protection client is not required.”

Since all employee assessments follow a specific template (AssessmentTemplate.docx), the best way to identify these documents for Data Loss Prevention (DLP) is to create a document fingerprint of that template.

Document fingerprinting allows Microsoft 365 DLP policies to recognize documents based on their structure and format, even when content inside varies (such as different employee names and results). By creating a fingerprint of AssessmentTemplate.docx, any copy derived from that template will be automatically detected by the DLP policy and blocked from being emailed externally.

Steps to implement:

● Create a document fingerprint of AssessmentTemplate.docx using PowerShell and the Microsoft Purview compliance portal.

● Apply a DLP policy to prevent external sharing of documents matching this fingerprint.

● Test the policy by attempting to email an assessment externally.

To review a Microsoft 365 Copilot usage report, you need to use Data Security Posture Management for AI (DSPM for AI) in the Microsoft Purview portal. DSPM for AI provides insights into AI-related activities, including Copilot usage, risk assessments, and data security posture related to AI interactions within Microsoft 365.

The issue where users sometimes can upload files to cloud services and sometimes cannot suggests inconsistent enforcement of Endpoint DLP policies. This can be caused by the unallowed browsers in the Microsoft 365 Endpoint DLP settings are NOT configured. Also, there are file path exclusions in the Microsoft 365 Endpoint DLP settings.

Endpoint DLP can block uploads only when using unallowed browsers. If unallowed browsers are not configured, users might be able to bypass restrictions by switching to a different browser. This could explain why uploads sometimes work and sometimes don’t, depending on which browser is used.

File path exclusions allow certain files or folders to be exempt from DLP restrictions. If a specific file location is excluded, files stored there won’t trigger DLP policies, leading to inconsistent behavior. This could result in some uploads being blocked while others are allowed.

Marking Tailspin_scanner.exe as "Unsanctioned" in Microsoft Defender for Cloud Apps only blocks its usage in cloud-based activities (such as accessing SharePoint, OneDrive, or Exchange Online). However, it does not prevent a locally installed application on Windows 11 devices from accessing sensitive files.

To block Tailspin_scanner.exe from accessing sensitive documents while allowing it to access other files, the correct solution is to use Microsoft Purview Endpoint Data Loss Prevention (Endpoint DLP) and add Tailspin_scanner.exe to the Restricted Apps list.

Endpoint DLP allows you to block specific applications from accessing sensitive files while keeping general access available. Restricted Apps List in Endpoint DLP ensures that Tailspin_scanner.exe cannot open, copy, or process protected documents, but it can still function normally for non-sensitive content.

The requirement states that all Microsoft 365 data for users must be retained for at least one year. In Microsoft 365, retention policies must be configured for each type of data storage.

Step 1: Identifying Where Data is Stored

From the case study, users store data in the following locations:

● SharePoint Online sites

● OneDrive accounts

● Exchange email

● Exchange public folders

● Teams chats

● Teams channel messages

Since these locations fall under two broad categories:

● Microsoft Exchange data (Emails, Public folders)

● SharePoint, OneDrive, and Teams data

Step 2: Required Retention Policies

1️. A single retention policy can cover:

● SharePoint Online

● OneDrive

● Microsoft Teams

2. A second retention policy is required for:

● Exchange (Emails & Public Folders)

Thus, the minimum number of retention policies required to meet the requirement is 2.

Microsoft 365 retention policies can be applied broadly across multiple services with just two policies:

● One for Exchange & Public Folders

● One for SharePoint, OneDrive, and Teams

There's no need for separate policies for each individual workload unless different retention durations are required, which is not stated in the requirement.
