After migrating SAP to AWS, the team must prove the new system performs at least as well as the source. Which comparison is objective?
Show answer and explanation
Answer: B
SAP standard application benchmarks apply a fixed, documented workload and report throughput in SAPS, which is hardware-independent. Running the same benchmark on the source and the AWS target produces comparable numbers and shows whether the target meets or exceeds the old capacity. vCPU counts, CPU utilization, and user impressions are not normalized measures and can hide differences in memory bandwidth, storage latency, and tuning.
Why the other options are wrong
- A. User perception is subjective and not repeatable, so it cannot prove equivalence.
- C. vCPU counts do not account for microarchitecture, SAPS per core, memory, or I/O, so equal counts can deliver very different throughput.
- D. Utilization shows how busy the host is, not how much work it can complete.
Exam tip. Objective before and after performance means the same SAP benchmark compared in SAPS.
