Question #3

Hotspot Question
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.

Reveal Solution  Discussion  0

Correct Answer:


Explanation:
Box 1: Yes
Users with a Microsoft 365 E5 (or E3) license have access to Microsoft 365 Copilot Chat at no additional cost. Within Copilot Chat, they can use Agent Builder to create basic Copilot agents, including agents grounded in public web data (when the feature is enabled in the tenant). A full Microsoft 365 Copilot add-on license is not required for this basic agent creation capability.
Box 2: Yes
The Analyst agent (along with other premium agents like Researcher) is a Microsoft-provided advanced reasoning agent. It is only available to users who have the Microsoft 365 Copilot add- on license. Users with only E3/E5 base licenses cannot access this premium agent.
Box 3: Yes
This is one of the key features of Agent Builder in Microsoft 365 Copilot. Users can simply describe in natural language what they want the agent to do, and Copilot assists in creating and configuring the agent.

Question #4

Hotspot Question
Your organization has a Microsoft 365 subscription.
You need to use Microsoft Purview to meet the following requirements:
- Prevent users from sharing files that contain Personally Identifiable Information (PII).
- Use machine learning to train a model that detects sensitive content.
Which Microsoft Purview solution should you use for each requirement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Reveal Solution  Discussion  0

Correct Answer:


Explanation:
Box 1: Data Loss Prevention (DLP)
DLP policies in Microsoft Purview are specifically designed to detect and prevent the sharing of sensitive information such as PII (social security numbers, credit card numbers, passport numbers, etc.). You can create DLP policies that automatically block or restrict users from sharing files containing PII across M365 services like SharePoint, OneDrive, Teams, and email.
Box 2: Information Protection
Microsoft Purview Information Protection includes trainable classifiers, which use machine learning to detect sensitive content. You can create custom trainable classifiers by providing sample data to "train" the model to recognize specific types of sensitive content unique to your organization. This is distinct from DLP (which enforces the policy) - Information Protection is where the classification/detection model is built.

Question #5

Hotspot Question
You have a Microsoft SharePoint site named Site1 and a security group named Group1.
You need to prevent all users that currently have access to Site1 from accessing the site content, unless the user is also a member of Group1.
Which settings should you configure? To answer, select the appropriate settings in the answer area.

Reveal Solution  Discussion  0

Correct Answer:


Explanation:
To achieve the goal of restricting site access so that only members of Group1 can access the content-even if other users previously had permissions-you need to configure the Restricted site access setting.
