AB-900 - Identify the core features and objects of Microsoft 365 services (32% of the exam) - Section 1.1
Identify the core objects of Microsoft 365 services and the admin centre that configures each.
How licence types assigned to users and groups affect feature access; organisation configuration in the Microsoft 365 admin center; mailboxes and distribution groups in the Exchange admin center; sites, libraries and folders in the SharePoint admin center; teams, channels and policies in the Teams admin center. The most-tested skill is matching a stated administrative task to the correct admin centre.

A new starter reports that they cannot use any Office apps because their account shows no assigned product licence. An administrator wants to view the user's account, assign a Microsoft 365 licence, and reset the user's password from one place. Which admin centre should the administrator open?
AThe Microsoft 365 admin center, from the active users pagecheck_circle Correct
BThe Teams admin center, from the user management page
CThe SharePoint admin center, from the more features page
DThe Exchange admin center, from the mailboxes page
User accounts, licence assignment, and password resets are handled together on the active users page of the Microsoft 365 admin center. The Microsoft 365 admin center owns user account objects, so its active users page consolidates viewing an account, assigning or removing licences, and resetting passwords into a single management surface.
Why A is correct: The active users page in the Microsoft 365 admin center is where an administrator views an account, assigns product licences, and resets passwords, covering all three tasks in one place.
Why B is wrong: The Teams admin center lists users for Teams policy assignment, so it seems to manage accounts, but it cannot assign product licences or reset a user's password.
Why C is wrong: SharePoint governs sites and their access, so it can feel like user administration, but it offers no licence assignment or password reset for accounts.
Why D is wrong: The Exchange admin center shows recipient mailboxes, which is close to user data, but it does not assign Microsoft 365 licences or reset account passwords.
Exam traps in Identify the core features and objects of Microsoft 365 services
Answers that look right on this material and are not. Each one is a distractor from a different question in the AB-900 bank for this domain.
SharePoint admin center
errorWhy it is wrong: SharePoint underpins the files behind a team, so this centre is tempting, but meeting and messaging policies for Teams are set in the dedicated Teams console, not here.
The SharePoint admin center, because Teams files are stored in SharePoint
errorWhy it is wrong: Tempting because Teams files do live in SharePoint, but meeting and recording policies are not managed there.
The Exchange admin center, which manages mailboxes and mail flow
errorWhy it is wrong: Tempting because it manages a user's mailbox, but it does not reset account passwords or manage tenant-wide licence assignment.
