Correct Answer: CDWhen a customer needs to replace aging infrastructure but cannot house certain applications in the public cloud due to compliance issues, an HPE solution that keeps data on-premises but provides cloud-like capabilities is ideal. An operating lease by HPE Financial Services allows the customer to avoid owning hardware and instead leases it, maintaining flexibility and potentially better financial management. An HPE GreenLake solution offers a pay-per-use model and cloud-like experience for on-premises infrastructure, enabling compliance with regulatory requirements while providing scalability and efficiency. Thus, the recommended solutions are an operating lease by HPE Financial Services and an HPE GreenLake solution.
