Which cloud service model gives the consumer the most control over the guest operating system and applications?
The correct answer is A. IaaS (Infrastructure as a Service). With IaaS, you rent raw servers and networks and can install any OS and applications you want. In PaaS, the provider manages the OS layer. SaaS customers only use the application. FaaS is even more abstract.
