Which cmdlet is used to validate the IRM configuration of a tenant?

The cmdlet that is used to validate the Information Rights Management (IRM) configuration of a tenant is Test-IRMConfiguration. This cmdlet performs a specific test of the IRM settings and verifies whether the configuration is set up correctly for the organization. By executing this cmdlet, administrators can ensure that necessary IRM services are functioning as expected, which is crucial for protecting sensitive information within the organization.

In contrast, Get-IRMConfiguration provides a retrieval function that allows administrators to see the current IRM settings but does not validate them. Similarly, Set-IRMConfiguration is used to configure or modify existing IRM settings rather than validate them. The cmdlet Validate-IRMConfiguration does not exist in the typical PowerShell cmdlets provided for managing IRM. Thus, Test-IRMConfiguration stands out as the correct choice because it specifically serves the purpose of validating the IRM configuration.
