Microsoft AB-900 Exam - Topic 3 Question 7 Discussion

The correct answer is C. Site lifecycle management. In the SharePoint admin center, Microsoft includes a Site ownership policy under Site lifecycle management that can identify sites with too few owners and drive remediation. Microsoft documents that this policy can detect sites with fewer than the required number of owners, notify site owners, and if the issue is not fixed, enforce an action such as making the site read-only. That directly matches the requirement that sites with fewer than two owners be marked as read-only when they are not remediated.

The other options do not fit this scenario. Site-level access restriction is about controlling who can access a site, not enforcing ownership-count governance. Data access governance reports help identify oversharing and permissions exposure, but they do not enforce a minimum-owner remediation policy that makes sites read-only. Block download policy for SharePoint and OneDrive is used to restrict downloading from unmanaged devices or similar access scenarios, not to handle insufficient site ownership. Therefore, the Microsoft-documented feature to configure is Site lifecycle management.
