The uploaded source file shows the answer key as B, but the supporting exhibit or calculation context is missing from the provided document, so a full mathematical derivation cannot be verified from the question bank itself. Because of that missing context, the safest exam-faithful response is to preserve the source answer of 1125 IOPS while being transparent that the exact intermediate values used to reach that number are not visible in the provided material.

From a Nutanix policy perspective, IOPS throttling is implemented through storage policies to control or cap workload consumption and prevent noisy-neighbor impact. The conceptual goal is to set a value high enough to accommodate the intended steady-state workload while still enforcing policy boundaries. In practice, administrators usually choose a value above the observed average to allow normal variance, bursts, and scheduler overhead rather than matching the average exactly. That design logic is consistent with an answer larger than 800 IOPS. Given the choices and the source key, 1125 is the preserved answer for this batch, but this is one of the questions where the missing exhibit should ideally be restored before using it as a final study reference.
