I would look at max CPU utilization and max Memory usage. Having 75% CPU usage would signify we have a proper utilization of cpu resources

Selected Answer: E
Proper utilization of VM resources, especially in a distributed computing environment like Spark, often involves efficient usage of CPU resources. A CPU utilization around 75% indicates that the CPU is being utilized without being fully saturated, allowing room for additional processing without causing excessive contention.

Selected Answer: E
An average CPU utilization around 75% is a good indicator of proper utilization of the VM's resources in a distributed computing environment. It suggests that the CPUs are being actively used for computation without being maxed out, which could indicate a bottleneck. It leaves some headroom to handle additional load without causing excessive queuing or delays.
