QuestionQ24

Analyze and Optimize VM Performance

A VM lacks enough resources to meet demand, resulting in performance bottlenecks. Based on the previous 30 days, the VM shows one or more of these baseline values:

  • CPU usage > 90% (moderate), 95% (high)
  • CPU ready time > 5%, 10%
  • Memory usage > 90%, 95%
  • Memory swap rate > 0 Kbps (no moderate value)

Which VM type is being described?

  • A Constrained VM
  • B Bully VM
  • C Inactive VM
  • D Over-provisioned VM
Explanation

A constrained VM does not have enough allocated CPU or memory resources for its workload. Persistently high CPU or memory utilization, elevated CPU ready time, and any memory swapping indicate resource contention and performance bottlenecks.
