After deploying a VM with a baseline CPU utilization below 80%, a cloud engineer notices the current CPU utilization stays in the 95% to 99% range. Which of the following describes how this should be

Deploying an additional VM is a horizontal scaling solution, which is effective for distributed workloads but doesn't address the root cause of high CPU on a single VM if it's due to memory pressure.

Enabling CPU hyperthreading provides logical cores and a modest performance boost, but it is insufficient to resolve severe CPU saturation (95-99%) caused by an underlying resource bottleneck like memory.

Increasing the CPU amount directly adds processing power, but if the actual bottleneck is memory, adding more CPU might only give the application more cores to use for memory-intensive operations like paging, not solving the root issue.

High CPU utilization can often be a symptom of insufficient RAM, where the operating system and applications spend excessive CPU cycles on memory management tasks like paging data to disk or performing garbage collection. Adding more RAM can alleviate this memory pressure, reducing CPU overhead and thus lowering utilization.
