CompTIA Cloud+ Practice Test

Which of the following is part of the PaaS consumer's responsibility regarding baseline configuration tests?

1. Application versions

2. CPU utilization

3. RAM utilization

4. Operating system versions

The correct answer is: CPU utilization

The responsibility of the PaaS (Platform as a Service) consumer regarding baseline configuration tests primarily relates to their application environment and performances, rather than the underlying infrastructure itself. In this context, CPU utilization is key since it is closely tied to how the application is expected to perform under various loads and configurations. By monitoring and testing CPU utilization, consumers can establish performance baselines and ensure that their applications run efficiently within the provided platform. While application versions and operating system versions are indeed important, they are often elements that the service provider oversees in a PaaS model. The consumers typically focus on managing how their applications perform in relation to the resources allocated to them, ensuring that the application's demands are accurately reflected and optimized based on real-time usage metrics, including CPU performance. RAM utilization is also critical for performance testing but is considered a lower-level concern than CPU performance in many contexts, as CPU performance tends to have a more direct impact on application responsiveness and speed. Thus, keeping a close watch on CPU utilization allows the PaaS consumer to assess and adjust their configurations to optimize overall application performance within the cloud environment.
