The correct answer is C. EXF900. Option C (EXF900) is correct because the "F" in EXF900 denotes an all-flash ECS node, meaning it uses NVMe/flash storage rather than spinning hard drives, delivering the high IOPS and low latency required by the application described.

Explanation

Option C (EXF900) is correct because the "F" in EXF900 denotes an all-flash ECS node, meaning it uses NVMe/flash storage rather than spinning hard drives, delivering the high IOPS and low latency required by the application described.

The distractors - EX300, EX500, and EX5000 - are all HDD-based ECS nodes optimized for capacity and cost-efficiency rather than performance; spinning disk inherently has higher latency and cannot match flash's transaction throughput, making them unsuitable for latency-sensitive workloads.

Memory tip: The letter "F" = Flash = Fast. Any time an exam question mentions low latency or high transactions per second with ECS, look for the node with an "F" in its model name.
