Question types

Choose the best answer from the options, or the stated number of answers when a question asks for more than one.

CertUp example

Copilot shows an employee a document that should be private. What is the most likely cause?

  1. The employee already has access to the document
  2. Copilot ignores permissions
  3. The document has no file extension
  4. The employee has no Copilot licence
Show answer

A. Copilot only surfaces content the signed-in user can already open, so the fix is to correct the permissions.

Most candidates spend 10–30 hours. Plan for the low end if you already administer Microsoft 365; plan for the high end if Purview, identity or data protection are new to you.
