Question 1

You have a Microsoft 365 E5 subscription that uses Microsoft Purview data loss prevention (DLP) policies. You need to identify which users uploaded confidential files to external websites. The solution must minimize administrative effort. What should you use in the Microsoft Purview portal?

A. Content explorer
B. Audit
C. Data explorer
D. Activity explorer
Show Answer
Correct Answer: D
Explanation:
Use Activity explorer. It displays DLP-related activities, including user and file details, and can help identify uploads of sensitive or confidential files to external websites. This is the most direct option for investigating those activities with minimal administrative effort.

Question 2

You have a Microsoft 365 E5 subscription. You need to apply data loss prevention (DLP) policies to the following: • Microsoft Exchange Online mailboxes • Microsoft SharePoint Online sites • Microsoft 365 Copilot • Microsoft OneDrive accounts • On-premises repositories What is the minimum number of DLP policies required to achieve the goal?

A. 1
B. 2
C. 3
D. 4
E. 5
Show Answer
Correct Answer: B
Explanation:
Two DLP policies are required. One policy can cover Exchange Online, SharePoint Online, OneDrive, and on-premises repositories. Microsoft 365 Copilot must be configured in a separate DLP policy because it cannot be combined with those other locations in the same policy.

Question 3

You need to be alerted when users share sensitive documents from Microsoft OneDrive to any users outside your company. What should you do?

A. From the Microsoft Entra admin center, configure an Identity Protection policy.
B. From the Microsoft Purview portal, start an eDiscovery search.
C. From the Microsoft Purview portal, start a data investigation.
D. From the Microsoft Purview portal, create a data loss prevention (DLP) policy.
Show Answer
Correct Answer: D
Explanation:
Create a Microsoft Purview data loss prevention (DLP) policy configured to detect sensitive documents in OneDrive when they’re shared with people outside the company and generate an alert.

Show Answer
Correct Answer: Doc1: Yes Doc2: No Doc3: No
Explanation:
Doc1 and Doc2 are both covered by the six-year Policy3, which takes precedence over shorter retention periods. Moving Doc3 to Site4 does not make the four-year policy apply to it.

Question 5

You have an Endpoint data loss prevention (Endpoint DLP) policy that contains the actions shown in the Actions exhibit. (Click the Actions tab.)

Question 6

HOTSPOT You have a Microsoft 365 subscription. You configure encrypted email for the subscription. You need to ensure that recipients of encrypted emails sign in to the message encryption portal to access the content of the emails. The solution must ensure that they sign in by using a Microsoft Entra account or a federated account. How should you complete the PowerShell command? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Show Answer
Correct Answer: Set-OMEConfiguration -OTPEnabled $false
Explanation:
Disabling one-time passcodes requires recipients to authenticate to the message encryption portal with an account instead of using a passcode.

Question 7

You have a Microsoft 365 subscription that uses Microsoft Purview Insider Risk Management. The subscription has a policy named Policy1 that detects potential insider risks based on exfiltration activities. You discover multiple high-severity alerts for Policy1. When you review the alerts, you discover that the activities that triggered alerts have a low-risk score. You need to ensure that you only receive high-severity alerts for activities that have a high-risk score. What should you modify in Policy1?

A. the time range
B. the triggers
C. the indicators
D. the notification settings
Show Answer
Correct Answer: C
Explanation:
Modify the indicators and their thresholds. These settings control which exfiltration activities are monitored and how strongly they contribute to a user’s risk score, helping ensure high-severity alerts correspond to high-risk activity. The time range and triggers control when activity is considered, while notification settings control delivery.

Question 8

HOTSPOT You have a Microsoft 365 E5 subscription that contains two Microsoft SharePoint Online sites named Site1 and Site2. Site1 contains the files shown in the following table. Site2 contains the files shown in the following table. From the Microsoft Purview portal, you create the content searches shown in the following table. For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Show Answer
Correct Answer: Search1: No Search2: No Search3: Yes
Explanation:
Search1 requires User1 as the author, so it excludes File2.docx. Search2 requires a .docx extension, so it excludes FileA.pptx. Search3 matches FileB.docx because author matching is case-insensitive.

Question 9

You have a Microsoft 365 tenant that uses Microsoft Purview Information Protection. You create a sensitivity label named Sensitivity1 and configure Sensitivity1 to encrypt files and emails. You publish Sensitivity1. You discover that users are NOT prompted to apply Sensitivity1 to their files and email. You need to ensure that the users must apply Sensitivity1 to their files and email before saving the files or sending the emails. The solution must meet the following requirements: • Prevent users from removing the label from the files and emails. • Minimize administrative effort. What should you do?

A. Select Control access for Sensitivity1.
B. Create a new auto-labeling policy.
C. Configure the protection settings of the sensitivity label policy for Sensitivity1.
D. Publish Sensitivity1 by creating a label policy.
Show Answer
Correct Answer: C
Explanation:
Configure the existing sensitivity label policy to require users to apply a label to files and emails, and require justification if they try to remove or lower the label. This makes labeling mandatory and avoids creating a redundant policy.

You need to ensure that only Microsoft Exchange Online emails containing the serial numbers are retained for five years. Which three objects should you create?

A. an auto-labeling policy
B. a retention policy
C. a data loss prevention (DLP) policy
D. a trainable classifier
E. a sensitivity label
F. a sensitive info type
G. a retention label
Show Answer
Correct Answer: A, F, G
Explanation:
Create a sensitive info type to detect the unique 12-character alphanumeric serial numbers, a retention label configured to retain content for five years, and an auto-labeling policy that applies the label to matching Exchange Online emails.
