In Platform as a Service (PaaS), the cloud provider manages the hardware, operating system, and middleware, while the customer is responsible for managing data and applications.
Why Not B (SaaS): In SaaS, the provider manages all layers, including applications and data, leaving no responsibility for the customer.
Why Not C (IaaS): In IaaS, the customer manages the OS, data, and applications, while the provider only handles the hardware.
Why Not D (CaaS): CaaS (Container as a Service) is not a primary cloud model described in the CompTIA objectives and is less commonly referenced.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 4.1, cloud computing models.
