The correct PowerShell cmdlet to perform the drain action to move all active workloads to the remaining nodes in a specific scale unit on an Azure Stack Hub Integrated System is "C. Drain-AzsScaleUnitNode".
When a node in a scale unit needs maintenance or is being decommissioned, it is important to ensure that any active workloads running on that node are gracefully moved to the remaining nodes in the scale unit. The Drain-AzsScaleUnitNode cmdlet is used to evacuate active workloads from a node, and moves them to other nodes in the same scale unit.
Here is a brief explanation of the four cmdlets mentioned in the question:
A. Enable-AzsScaleUnitNode - This cmdlet is used to enable a node that has been disabled in a scale unit.
B. Repair-AzsScaleUnitNode - This cmdlet is used to repair a failed or unhealthy node in a scale unit.
C. Drain-AzsScaleUnitNode - This cmdlet is used to evacuate active workloads from a node in a scale unit, and moves them to other nodes in the same scale unit.
D. Disable-AzsScaleUnitNode - This cmdlet is used to disable a node in a scale unit.
In summary, if you need to perform a drain action to move all active workloads to the remaining nodes in a specific scale unit on an Azure Stack Hub Integrated System, you would use the "Drain-AzsScaleUnitNode" PowerShell cmdlet.
