Why PowerShell Matters for MS-102

Microsoft 365 administration often requires managing thousands of users or configuring complex tenant settings.

PowerShell provides the necessary scalability and automation that the GUI cannot match, making it a major focus of the MS-102 exam.

Connecting to M365 Services

Before you can run any administrative scripts, you need to connect to the respective M365 services.

The `Connect-ExchangeOnline`, `Connect-MgGraph`, and `Connect-SPOService` cmdlets are your gateways to managing different workloads.

Managing Users and Groups

Bulk user creation and group management are common practical scenarios.

Scripts utilizing `New-MgUser` or importing CSVs for batch processing are heavily tested concepts.

Best Practices and Security

When writing scripts, always follow the principle of least privilege and use secure methods for credential handling.

Modern authentication and certificate-based connections are preferred over basic authentication.
