You have a Microsoft 365 E5 subscription.
You need to create static retention policies for the following locations:
● Teams chats
● Exchange email
● SharePoint sites
● Microsoft 365 Groups
● Teams channel messages
What is the minimum number of retention policies required?

  1. 1
  2. 2
  3. 3
  4. 4
  5. 5

Answer(s): C

Explanation:

In Microsoft Purview Data Lifecycle Management, different Microsoft 365 locations require separate retention policies because they fall under different storage and compliance models.
Teams Chats & Teams Channel Messages (1 Policy) require a separate retention policy because Teams messages are stored differently than Exchange and SharePoint content. One policy can cover both Teams chats and Teams channel messages. Exchange Email (1 Policy) requires its own separate policy since emails are managed differently than Teams or SharePoint content. SharePoint Sites & Microsoft 365 Groups (1
Policy) are both stored in SharePoint Online, so they can be managed under one policy.

You have a Microsoft 365 subscription.
You plan to retain the following audit log record types and activities for the next three years:
● CopilotInteraction: All activities selected (1/1)
- Interacted with Copilot
● ComplianceDLPEndpoint: All activities selected (2/2)
- Matched DLP rule
- Removed DLP rule from document
● AzureActiveDirectory: 2 of 25 activities selected (2/25)
- Reset user password
- Changed user password
What is the minimum number of audit retention policies you should create to retain only the selected record types and activities?

  1. 1
  2. 2
  3. 3
  4. 5

Answer(s): A

Explanation:

You only need one Microsoft 365 audit retention policy to cover CopilotInteraction, ComplianceDLPEndpoint,
and AzureActiveDirectory for three years, as a single policy can be configured with a three-year duration to apply to all specified record types. However, this requires having a Microsoft 365 Enterprise E5 subscription and a 10-Year Audit Log Retention add-on license to meet the three-year retention requirement.

You have a Microsoft 365 E5 subscription that uses Microsoft Purview Advanced Message Encryption.
Users send emails to external recipients that use Gmail and Yahoo services.
You need to ensure that access to all encrypted email messages sent to both internal and external recipients automatically expires after 90 days. The solution must meet the following requirements:
● Messages must be encrypted by using Microsoft Purview Advanced Message Encryption.
● Prevent recipients from accessing the contents of encrypted messages after 90 days.
● Ensure that the expiration rules are applied to both internal and external recipients.
● Minimize administrative effort.
What should you include in the solution?

  1. A Microsoft Exchange Online retention policy
  2. A Microsoft Exchange Online transport rule that applies message encryption with an expiration date
  3. A Microsoft Purview sensitivity label with content expiration settings
  4. A Microsoft Purview sensitivity label policy

Answer(s): C

Explanation:

A Microsoft Purview sensitivity label with content expiration settings should be included in the project.
Requirement Purview Encryption & Internal/External scope: A Purview sensitivity label can be configured to apply encryption and restrict access across both internal and external recipients.
Requirement Expiration after set days: Sensitivity labels support explicit content expiration settings, e.g.,
expiring access after 90.
Low administration: Managing a single sensitivity label (and publishing it via a label policy) applies unified governance natively without requiring complex or hard-to-maintain Exchange transport/mail flow rules with custom scripts for every scenario.
