Explanation

Update-SCServiceConfiguration is used to update an existing service configuration to reflect changes made to the service template. Because the application has one upgrade domain per tier, VMM can roll updates through the deployment sequentially, keeping the application partially available during the update - this minimizes service interruption. Update-SCService (D) applies the updated configuration to the running service but should be run after Update-SCServiceConfiguration prepares the configuration object. Resolve-SCServiceTemplate (A) handles template version conflict resolution, and Update-SCVMConfiguration (C) operates at the individual VM level rather than the full service level.
