Which of the following tests would be MOST appropriate when over allocate storage on VMs in a development cluster?

Penetration testing is a security technique used to identify exploitable vulnerabilities in systems, not a measure of storage performance under over-allocation conditions.

Vulnerability scanning identifies known security weaknesses and misconfigurations in software or systems, and does not evaluate storage capacity or I/O performance.

Latency testing is most appropriate because over-allocation (thin provisioning beyond physical capacity) causes I/O contention and storage queue depth increases, directly manifesting as elevated read/write latency. When physical storage is overcommitted, VMs compete for actual disk I/O, and measuring latency reveals how severely performance degrades as utilization approaches or exceeds physical capacity. This test validates whether the over-allocation level is operationally acceptable before it impacts production workloads.

Bandwidth determination measures network throughput capacity, which is unrelated to the I/O performance issues caused by over-allocating storage on VMs.
