CV0-004 Practice Question: A cloud administrator is troubleshooting a…
A cloud administrator is troubleshooting a performance issue in a virtualized environment. Which THREE of the following metrics should the administrator analyze to identify potential resource contention? (Select THREE.)
⚠ Common exam trap
The trap here is that candidates often select network latency or swap file usage as signs of resource contention, but these metrics are not direct indicators of hypervisor-level contention for CPU, memory, or storage in a virtualized environment.
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
✓
CPU ready time
CPU ready time measures the time a virtual machine is ready to execute instructions but is waiting for the hypervisor to schedule physical CPU resources. High ready time directly indicates CPU contention, as the VM is being starved of CPU cycles by other VMs on the same host.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
CPU ready time
Why this is correct
High CPU ready time means the VM is waiting for CPU cycles due to contention.
- ✓
Disk queuing
Why this is correct
Disk queuing indicates I/O requests are waiting, suggesting storage contention.
- ✗
Swap file usage
Why it's wrong here
Swap usage indicates the VM is using disk as memory, but ballooning is a more direct indicator.
- ✗
Network latency
Why it's wrong here
Network latency may be due to network issues, not necessarily resource contention.
- ✓
Memory ballooning
Why this is correct
Ballooning is a sign that the hypervisor is reclaiming memory from the VM due to contention.
