SK0-005 troubleshooting Practice Question
A virtualized server running multiple VMs experiences a sudden performance degradation during peak hours. Storage latency spikes and CPU ready time increases significantly. The hypervisor shows high memory overcommitment but no swapping. Which action would most likely resolve the issue without adding hardware?
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
✓
Migrate one or more VMs to another host
Option B is correct because migrating VMs reduces resource contention on the host, lowering CPU ready time and potentially alleviating storage I/O pressure. Option A would only address memory pressure, not CPU ready. Option C is already enabled by default and would not resolve high ready time. Option D might help CPU contention but could degrade application performance and does not address storage latency directly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduce the number of vCPUs assigned to each VM
Why it's wrong here
Reducing vCPUs can lower CPU ready time but may also impair application performance and does not directly resolve storage latency.
- ✗
Increase memory reservation for all VMs
Why it's wrong here
Memory reservations guarantee memory availability but do not reduce CPU ready time or storage latency.
- ✓
Migrate one or more VMs to another host
Why this is correct
Moving VMs to another host spreads the workload, decreasing CPU contention and storage I/O load on the original host.
- ✗
Enable transparent page sharing
Why it's wrong here
Transparent page sharing is typically enabled by default and primarily conserves memory; it does not address CPU or storage bottlenecks.
