A police records bureau will invite outside engineering reviewers to a SharePoint site. Which SharePoint site role best fits reviewers who should read content but not change site settings or edit files?

When a police records bureau invites outside engineering reviewers to a SharePoint site and those reviewers should read content but not change site settings or edit files, the best-fit built-in site role is Visitors. Visitors typically receive read-oriented permissions: they can view pages and documents without editing files or administering the site. That matches least-privilege review access for external or partner engineers who need visibility into records packages without becoming content authors or site admins.

Owners fails by concept because Owners can manage site settings and permissions—far more privilege than read-only review requires. Members fails because Members generally can edit and contribute content, which exceeds a read-only reviewer need. Designers fails because Designers can modify site pages, lists, and appearance settings—far more privilege than read-only review requires.

Exam caveat: Know the Owners / Members / Visitors triad for SharePoint site roles. Read-only review maps to Visitors (or a custom read permission level). Do not pick Designers when the stem is about read-only access, because Designers can alter site structure and layout.

Operational check: add the engineering reviewers to the site Visitors group (or a SharePoint group with read permissions), confirm they can open the intended documents, attempt an edit with a reviewer test account to ensure it fails, confirm they cannot open site settings, and document whether access is via Microsoft Entra guest accounts consistent with police records external-sharing policy.
