You have a Microsoft 365 E5 tenant.
You need to add a new keyword dictionary.
What should you create?
To add a new keyword dictionary in Microsoft Purview Data Loss Prevention (DLP), you must create a Sensitive Information Type (SIT).
Sensitive Info Types (SITs) allow you to define custom detection rules, including keyword dictionaries, regular expressions, and functions for identifying sensitive content in emails, documents, and other Microsoft 365 locations. A keyword dictionary is a list of predefined words/phrases that Microsoft Purview can use to identify and classify content for DLP policies.
Steps to add a keyword dictionary:
1. Go to Microsoft Purview compliance portal
2. Navigate to Data classification > Sensitive info types
3. Create a new sensitive info type
4. Add a keyword dictionary
5. Save and use it in a DLP policy
You have a Microsoft 365 E5 subscription.
You need to ensure that encrypted email messages sent to an external recipient can be revoked or will expire within seven days.
What should you configure first?
To ensure that encrypted email messages sent to external recipients can be revoked or expire within seven days, you need to configure a sensitivity label with encryption settings in Microsoft Purview Information Protection. A sensitivity label allows you to encrypt emails and documents, set expiration policies (e.g., emails expire after 7 days), and enable email revocation
How to configure it?
Go to Microsoft Purview compliance portal Information Protection
Create a sensitivity label
Enable encryption and configure the content expiration policy
Publish the label to users

You have a Microsoft 365 subscription.
You have a user named User1. Several users have full access to the mailbox of User1.
Some email messages sent to User1 appear to have been read and deleted before the user viewed them.
When you search the audit log in the Microsoft Purview portal to identify who signed in to the mailbox of User1, the results are blank.
You need to ensure that you can view future sign-ins to the mailbox of User1.
Solution: You run the Set-MailboxFolderPermission -Identity "User1" -User User1@contoso.com -AccessRights Owner command.
Does that meet the goal?
The Set-MailboxFolderPermission -Identity 'User1' -User User1@contoso.com -AccessRights Owner command is incorrect. This assigns folder permissions but does not enable auditing. It does not track who accessed the mailbox or deleted emails.

You have a Microsoft 365 tenant and 500 computers that run Windows 11. The computers are onboarded to Microsoft Purview.
You discover that a third-party application named Tailspin_scanner.exe accessed protected sensitive information on multiple computers. Tailspin_scanner.exe is installed locally on the computers.
You need to block Tailspin_scanner.exe from accessing sensitive documents without preventing the application from accessing other documents.
Solution: From the Microsoft 365 Endpoint data loss prevention (Endpoint DLP) settings, you add a folder path to the file path exclusions.
Does this meet the goal?
Adding a folder path to the file path exclusions in Microsoft 365 Endpoint DLP does not prevent Tailspin_scanner.exe from accessing protected sensitive information. Instead, it would exclude those files from DLP protection, which is not the intended outcome.
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.

You have a Microsoft 365 subscription.
You have a user named User1. Several users have full access to the mailbox of User1.
Some email messages sent to User1 appear to have been read and deleted before the user viewed them.
When you search the audit log in the Microsoft Purview portal to identify who signed in to the mailbox of User1, the results are blank.
You need to ensure that you can view future sign-ins to the mailbox of User1.
Solution: You run the Set-Mailbox -Identity "User1" -AuditEnabled $true command.
Does that meet the goal?
To track who accesses User1's mailbox, you need to enable mailbox auditing for User1. By default, Exchange mailbox auditing is not enabled per mailbox (even though it is enabled tenant-wide).
The Set-Mailbox -Identity 'User1' -AuditEnabled $true command enables audit logging for mailbox actions like:
Read emails
Delete emails
Send emails as User1
Access by delegated users
Once enabled, you can search for future sign-ins and actions in the Microsoft Purview audit logs.
