LFCS Question #438: Real Exam Question with Answer & Explanation

Question

When performing a capacity planning exercise, when would taking measurements be most approriate?

Options

• ADuring successful operation.
• BDuring an overload or an episode.
• CAfter an overload or an episode.
• DAfter replacing problematic hardware.

Explanation

This question asks about the most appropriate time to take measurements during a capacity planning exercise.

Common mistakes.

• B. Taking measurements during an overload or an episode captures abnormal system behavior and skewed resource usage, which is not representative of normal operating conditions for proactive capacity planning.
• C. Measuring after an overload or an episode only provides insights into the system's state post-problem, which is reactive and less useful for proactive capacity planning and forecasting future needs.
• D. While replacing hardware is part of capacity management, taking measurements only after replacement doesn't provide the historical baseline or trend data necessary for comprehensive capacity planning; continuous or periodic measurements are generally required.
