Community Insight

This question tests the prerequisite order for associating an information barrier segment with a SharePoint site, and the common trap is assuming that enabling SharePoint information barriers or running Set-SPOSite is the first step.

To add an information barrier segment to a SharePoint Online site, you must first create an information barrier policy that includes the segment. This guide explains why creating the policy is the required first step before using Set-SPOSite to link Segment1 to Site1.

The most common wrong answer is B (Run the Set-SPOTenant cmdlet), because candidates focus on enabling information barriers in SharePoint and OneDrive with Set-SPOTenant -InformationBarriersSuspension $false, but the question already assumes the segment exists and asks for the next step to link it to a site.

Think this one is B To enable information barriers in SharePoint and OneDrive, run the following command: Set-SPOTenant -InformationBarriersSuspension $false https://learn.microsoft.com/en-us/purview/information-barriers-sharepoint

Ruslan23 👍 2 Selected: C

C is correct.

SDiwan 👍 3 Selected: B

Ok I belive correct answer is "B. Run Set-SPOTenant" as the question asks "what should you do first". By default information barriers are not enabled in SPO and OneDrive, so we need to enable it using command: Set-SPOTenant -InformationBarriersSuspension $false Option C, is anyways wrong as Information barrier policy defines which segment can interact with which other segments. Assigning segment to SharePoint site does not need information barrier policy. The question specifically asks "You need to add Segment1 to Site1." , so nothing to do with information barrier policy. To add segment1 to site 1, the approach is to use command Set-SPOSite -Identity <site URL> -AddInformationSegment <segment GUID> Refer: https://learn.microsoft.com/en-us/purview/information-barriers-sharepoint

Its actually step 3, but who is counting LOL Than, you'd want to To: "enable information barriers in SharePoint and OneDrive with PowerShell" PS>Set-SPOTenant -InformationBarriersSuspension $false with love~

Yes, it is C. "Information barrier segments need to be linked to sites through information barrier policies." No policy, No Honey.

Expert Analysis

Why the Answer Is Correct

Creating an information barrier policy is the required first step because Microsoft Purview links information barrier segments to SharePoint sites through information barrier policies. Until a policy that includes Segment1 exists, the segment cannot be associated with Site1. The Set-SPOSite cmdlet is the tool used to actually add the segment to the site, but it must be run after the policy is created. Therefore, after creating Segment1, the next action is to create an information barrier policy.

Why the Other Options Are Wrong

Option A (Run the Set-SPOSite cmdlet) is the action that performs the association, but it is not the first step; the policy must exist first. Option B (Run the Set-SPOTenant cmdlet) enables information barriers in SharePoint and OneDrive, which is a tenant-level prerequisite but not the immediate step after creating a segment. Option D (Modify the permissions of Site1) is unrelated to information barriers and does not link a segment to a site.

Community Comment Notes

The community is split, with some learners voting for B. Dools cited the Set-SPOTenant command for enabling information barriers in SharePoint, and SDiwan argued that policies define interactions rather than site assignment. However, louisaok correctly noted that information barrier segments are "linked to sites through information barrier policies." Domza also acknowledged the enabling step but still chose C, and Ruslan23 simply stated C is correct. This confirms that the policy creation is the critical first step.

Exam Strategy

When a question asks what to do first, look for the step that creates the link between the segment and the site. Remember that policies are the bridge; without a policy, a segment cannot be associated with a SharePoint site.

Frequently Asked Questions

Why can’t I just run Set-SPOSite to add Segment1 to Site1?

Set-SPOSite performs the association, but Microsoft requires an information barrier policy to link the segment to the site first.

Is enabling information barriers in SharePoint with Set-SPOTenant required first?

It is a tenant-level prerequisite, but the immediate step after creating a segment is to create an information barrier policy that includes it.
