Microsoft Updated SC-401 Exam Questions and Answers by oren

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

When you configure Microsoft Purview DLP policies for the Teams chat and channel messages location, the following entities are protected:

1:1 and n:n chats (private chats between two or more users).

Team channel messages (including the General channel and all standard channels).

Private channel messages.

This means that if a DLP policy is applied to User1 and User2, it will monitor and enforce rules across:

Chats between User1 and User2 (1:1 or group chats).

Any channel conversations they participate in (General or other channels).

Private channels they belong to.

Incorrect options:

A (1:1/n chats and general channels only) → Excludes private channels, but DLP supports them.

B (1:1/n chats and private channels only) → Excludes general channels, but DLP supports them too.
