The human resources department was charged for a cloud service that belongs to another department. All other cloud costs seem to be correct. Which of the following is the MOST likely cause for this er

Cloud infrastructure templates (such as AWS CloudFormation or Azure ARM templates) often include parameters that specify the billing account, subscription, or cost center to which deployed resources are charged. If a template for another department's service was configured with HR's billing context, every resource provisioned from that template would be incorrectly invoiced to HR. Because only this one service is affected and all other costs are correct, a template-level misconfiguration scoped to a specific deployment is the most precise root cause.

A misconfigured chargeback rule would affect cost allocations broadly across multiple departments or services rather than producing a single isolated incorrect charge.

Incorrect security groups control inbound and outbound network traffic permissions and have no relationship to billing attribution or cost allocation.

Misconfigured resource tags can cause billing misattribution, but tag errors typically affect all resources sharing that tag rather than a single isolated cloud service.
