Question 23
UnclassifiedWhich storage validation test measures random I/O performance important for AI training checkpoints?
Correct answer: B
Explanation
Random 4K read/write IOPS measures how many small, random 4 KB input/output operations a storage system can handle per second. AI training checkpoints depend on frequent small random reads and writes, so this test reflects the "random I/O performance" that matters most for checkpoint workloads.
Why each option is right or wrong
A. Sequential read/write test
B. Random 4K read/write IOPS test
The relevant metric here is the 4 KB random I/O benchmark, because checkpointing workloads are dominated by many small, non-sequential metadata and tensor writes/reads rather than large contiguous transfers. In storage validation, IOPS is the standard measure for this pattern, and using 4 KB blocks specifically targets the small-operation behavior that stresses AI training checkpoint paths far more than throughput-oriented tests.
C. Large file copy test
D. Metadata operation test
