ISC2 Certified Cloud Security Professional (CCSP) Practice Question

During a weekly performance review of your production IaaS cluster, several Linux web-service VMs appear almost idle from inside the guest (CPU utilization <10 %), yet customer transactions are completing nearly twice as slowly as usual. Historical monitoring dashboards show no guest-level memory pressure and only moderate network usage. To determine whether the issue is caused by resource contention at the virtualization layer, which additional hypervisor-level metric should you examine first?

  • CPU ready time for each vCPU

  • Average disk queue length reported by the guest OS

  • Guest kernel context switch rate

  • TCP retransmission count on the virtual network adapter
