A customer is running an Online Transaction Processing (OLTP) application that requires high- speed access to the application files with a minimal latency. Which internal storage technology offers…
The correct answer is A. NVMe SSD. NVMe SSD (A) delivers the highest performance because it connects directly to the CPU via PCIe lanes, bypassing the storage controller bottleneck entirely - this gives it sub-millisecond latency and multi-gigabyte-per-second throughput that OLTP workloads demand. M.2 SATA (B)…

Explanation
NVMe SSD (A) delivers the highest performance because it connects directly to the CPU via PCIe lanes, bypassing the storage controller bottleneck entirely - this gives it sub-millisecond latency and multi-gigabyte-per-second throughput that OLTP workloads demand.
M.2 SATA (B) uses the M.2 form factor but still runs the slower SATA protocol, capping throughput around 600 MB/s - the connector looks modern but the protocol is the limiting factor. SATA SSD (C) shares this same SATA bottleneck regardless of form factor, making it significantly slower than NVMe. SAS SSD (D) is enterprise-grade and faster than SATA, but it still uses a legacy serial interface that can't match NVMe's PCIe bandwidth or latency.
Memory tip: Think "NVMe = No Middleman" - it speaks directly to the CPU over PCIe, while SATA and SAS must go through a controller. When an exam asks about lowest latency or highest throughput, NVMe wins by architecture, not just speed ratings.
