A county must lift a legacy licensing server that needs a full Windows operating system the county controls. Which cloud service type fits that requirement?
Select an answer to reveal the explanation.
Short Explanation
If you still need the full OS keys in your pocket, you are in IaaS territory — think renting the virtual machine and running Windows yourself. SaaS is the finished app in a browser; PaaS lifts the OS burden on purpose. A CDN is not a licensing server.
Full Explanation
Infrastructure as a Service fits when a county must lift a legacy licensing server that needs a full Windows operating system the county controls. IaaS virtual machines provide virtualized compute, storage, and networking while customers manage the guest OS and applications—matching that control requirement for legacy software that assumes OS-level access. If the county must install, configure, and maintain Windows itself, IaaS is the service type to name. SaaS payroll in a browser offers no OS access and cannot host that licensing server model. Saying PaaS only never allows customer OS control correctly describes PaaS abstraction but therefore fails the requirement for OS control—PaaS is the wrong type here even though it is valuable for other apps. A content delivery network accelerates and caches content delivery; it does not replace the need for compute that runs a licensing server. Exam caveat: choosing IaaS for OS control also means accepting guest OS patching, hardening, and backup duties under shared responsibility. Operational check: confirm the licensing workload’s OS and application dependencies are documented on the VM plan, including who patches Windows monthly and how license server recovery is tested.
