MS-900 Practice Question: Describe Microsoft 365 pricing, licensing, and support
An administrator needs to assign Microsoft 365 licenses to new users in bulk. They have a CSV file with user details and want to use a script. Which tool should they use?
⚠ Common exam trap
Test-takers frequently confuse Azure CLI with Microsoft Graph PowerShell, assuming any command-line tool can manage Microsoft 365 licensing, but Azure CLI lacks the specific Graph API endpoints for license assignment.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Graph PowerShell
Microsoft Graph PowerShell is the correct tool because it provides cmdlets like `New-MgUser` and `Set-MgUserLicense` that can process a CSV file and assign licenses in bulk via the Microsoft Graph API. This is the modern, scriptable approach for automating license assignments without manual steps in a GUI.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Microsoft Graph PowerShell
Why this is correct
Microsoft Graph PowerShell is the correct choice because it exposes the Microsoft Graph API's license assignment capabilities through cmdlets such as Set-MgUserLicense. This module allows administrators to script the assignment of one or more licenses to users in bulk by specifying the user's UserPrincipalName and the corresponding SKU IDs, with the ability to disable service plans during assignment. It is the only listed option that provides a programmatic, automation-friendly interface for Microsoft 365 license management, making it ideal for dynamic or large-scale licensing operations.
- ✗
Microsoft 365 admin center
Why it's wrong here
The Microsoft 365 admin center is a graphical web portal, not a scripting tool. While you can manually assign or remove licenses for individual users via the Active Users page, it offers no native command-line interface or REST API for automated, scripted license assignment. For bulk operations, administrators must manually edit multiple users or use the limited CSV import feature, which still lacks the flexibility and repeatability of PowerShell scripting. Thus, it does not meet the requirement of assigning licenses via scripting.
- ✗
Azure CLI
Why it's wrong here
Azure CLI is the command-line tool for managing Azure resources, such as virtual machines, storage, and Microsoft Entra ID (now Microsoft Entra ID) objects via commands like 'az ad user'. However, it does not include any commands for assigning Microsoft 365 licenses; license assignment is a Microsoft Graph API operation, not an Azure Resource Manager operation. Even though Azure CLI can query Entra ID users, it cannot invoke the Graph's license assignment endpoints, making it unsuitable for this task.
- ✗
Exchange admin center
Why it's wrong here
The Exchange admin center (EAC) is a specialized management interface for Exchange Online, focusing on mailboxes, mail flow, transport rules, and other email-related settings. It contains no functionality for assigning Microsoft 365 subscription licenses to users; license assignment is handled at the tenant level via the Microsoft 365 admin center or through the Graph API. Even if a user needs an Exchange Online mailbox, the license that enables that mailbox must be assigned outside the EAC, so it is not a valid tool for this requirement.
