CV0-004 Troubleshooting Practice Question
A cloud administrator is investigating why a virtual machine is running slowly. The administrator checks the hypervisor performance metrics. Which TWO of the following metrics indicate CPU contention? (Choose TWO.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
High CPU ready time
CPU ready time (option A) and co-stop time (option C) are both indicators of CPU contention. Ready time is time a VM is ready to run but waiting for CPU; co-stop time is time a VM is stopped because another vCPU in the same VM is contending. Option E (High CPU usage percentage) is normal utilization, not contention. Option B (High disk queue depth) is storage-related. Option D (High memory ballooning) is memory-related.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
High CPU ready time
Why this is correct
CPU ready time directly measures wait time due to contention.
- ✗
High disk queue depth
Why it's wrong here
Disk queue depth indicates storage bottleneck.
- ✓
High CPU co-stop time
Why this is correct
Co-stop time occurs when vCPUs in a single VM are contending for physical cores.
- ✗
High memory ballooning
Why it's wrong here
Memory ballooning indicates memory pressure, not CPU.
- ✗
High CPU usage percentage
Why it's wrong here
High CPU usage indicates the VM is using CPU, not necessarily contention.
