GCP Cloud Digital Leader Practice Question

In the Infrastructure as a Service (IaaS) model, the provider delivers the fundamental computing resources-such as physical servers, networking, storage, and the virtualization layer-while the customer retains control of the operating system, middleware, runtime, and applications. By contrast, Platform as a Service (PaaS) abstracts away the operating system and runtime so customers focus mainly on code and data, and Software as a Service (SaaS) delivers complete applications managed entirely by the provider. Function as a Service (often referred to as serverless) abstracts even more, automatically handling provisioning and scaling of runtime resources for event-driven code. Therefore, the described responsibility split aligns with IaaS, not PaaS, SaaS, or FaaS.
