A cloud service administrator is consuming PaaS services and is performing baseline configuration tests. Which of the following is part of the PaaS consumer's responsibility with respect to the…

Application versions are a deployment and release management concern owned by the consumer, but they are not a metric collected during baseline configuration performance testing.

Under the PaaS shared responsibility model, the cloud provider manages the OS, runtime, middleware, and physical infrastructure, but the consumer is accountable for application performance and resource consumption. CPU utilization is a core performance metric the consumer must monitor during baseline configuration testing to verify the deployed application behaves within expected parameters. This metric falls squarely within the consumer's operational scope because it directly reflects how their workload uses the PaaS platform's provided compute resources.

RAM utilization is also a consumer-monitored resource metric, but CPU utilization is the primary indicator tested during application baseline configuration validation.

Operating system versions are patched and managed entirely by the PaaS provider, placing them outside the scope of the consumer's baseline configuration testing responsibilities.
