IPA IP 2026 Question 62
A question IPA Japan published in 令和8年度 ITパスポート試験 公開問題 問62, translated into English. ITPEC is based on the same exams.
Which of the following is an appropriate description concerning a benchmark test in the performance evaluation of a system?
Explanation
A standard evaluation program run on the actual system — a benchmark test measures performance by really executing a set workload.
A benchmark fixes a standard piece of processing and a program that performs it, runs that program on the system being evaluated, and measures the result, such as the processing time. Because every system runs the same standard workload, the measured values can be compared between systems.
Answer (d)
Why not others:
- •(a) — running the system's own data and programs on another, pseudo system imitates the target instead of measuring it; this is a simulation
- •(b) — modelling the system's operating characteristics in an easy-to-handle form and running the model is also simulation, used before the real system exists
- •(c) — adding up processing time from desk-calculated step counts, hardware performance and I/O counts is an estimate by calculation (as in the instruction-mix method), with nothing actually run
Key rule: Benchmark = run a standard program on the real system and measure; simulation = run a model or imitation; desk calculation = estimate from figures without running anything.
