You have a Microsoft 365 subscription that uses Microsoft Defender for Office 365.
Users collaborate on files in Microsoft Teams. Files that are identified as malicious cannot be opened, moved, copied, and shared, but users can still save local copies.
You need to configure file-based protection for the collaboration workloads. The solution must meet the following requirements:
● Apply malware protection to the files stored in Teams.
● Prevent users from retaining local copies of files identified as malicious.
What should you do? To answer, select the appropriate options in the answer area.
Note: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




Safe Attachments for SharePoint, OneDrive, and Teams scans files stored in collaboration workloads and blocks access to files identified as malicious.
Use Set-SPOTenant with the infected-file download restriction enabled to prevent users from downloading malicious files locally, closing the remaining path for retaining copies of files that Defender has identified as infected.

What should you configure?

  1. Microsoft Purview Message Encryption
  2. DMARC
  3. ARC
  4. DKIM

HOTSPOT (Drag and Drop is not supported)
You have a Microsoft 365 E5 tenant that contains a Microsoft SharePoint site named Site1. Site1 contains the files shown in the following table.

You create a sensitivity label named Sensitivity1 and an auto-label policy that has the following configurations:
● Name: AutoLabel1
● Label to auto-apply: Sensitivity1
● Choose locations where you want to apply the label: Site1
The Define content that contains sensitive info settings for AutoLabel1 is shown in the following exhibit.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Note: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




The auto-labeling condition requires the IP Address sensitive information type at High confidence with an instance count of 2 or more.
File1.docx contains only one matching instance, so the label is not applied. File2.txt contains two matching instances and File3.xlsx contains five, so both meet the configured threshold and receive the Sensitivity1 label.
