CV0-003 Question #108: Real Exam Question with Answer & Explanation
The correct answer is C: Latency testing. Over-allocating storage on VMs means more virtual storage is provisioned than physical capacity, which causes performance degradation most visibly through increased I/O latency as actual usage climbs.
Operations and Support
Question
Which of the following tests would be MOST appropriate when over allocate storage on VMs in a development cluster?
Options
- APenetration testing
- BVulnerability scan
- CLatency testing
- DBandwidth determination
Explanation
Over-allocating storage on VMs means more virtual storage is provisioned than physical capacity, which causes performance degradation most visibly through increased I/O latency as actual usage climbs.
Common mistakes.
- A. Penetration testing is a security technique used to identify exploitable vulnerabilities in systems, not a measure of storage performance under over-allocation conditions.
- B. Vulnerability scanning identifies known security weaknesses and misconfigurations in software or systems, and does not evaluate storage capacity or I/O performance.
- D. Bandwidth determination measures network throughput capacity, which is unrelated to the I/O performance issues caused by over-allocating storage on VMs.
