Exam Day Checklist

  • Copilot only returns content the user can already open, so oversharing is a permissions problem: find it with data access governance reports and fix it with SharePoint Advanced Management controls such as restricted access control.
  • Use least privilege: License Administrator assigns licenses, and AI Administrator changes Copilot settings and approves agent requests without Global Administrator rights.
  • Pay-as-you-go takes a billing policy connected to a service, and a budget only sends alerts; it doesn't stop usage.
  • Pick the right admin center: Microsoft 365 for Copilot settings, usage reports, and the agent registry and requests; Power Platform for Copilot Studio environments, data policies, and credits; Purview for labels, DLP, and DSPM for AI.
  • Expect renamed and retiring features: DSPM for AI is now labeled classic, Content search lives inside eDiscovery, and Restricted SharePoint Search is retiring in favor of Restricted Content Discovery.
  • Read the final sentence of a long scenario first to find the actual question.
  • Watch for qualifiers such as NOT, BEST, and MOST appropriate.
  • You have 45 minutes and need 700 to pass. Flag hard questions and come back; change an answer only with a clear reason.
