What are the five key factors that equate to customer requirements for storage components?

Question

Options

• AReturn on Investment, capability, expandability, and total cost of ownership
• BEfficiency, return on investment, ecology, risk management, and cost
• CCost, accuracy, readability, speed, and expandability
• DPerformance, cost, capacity, reliability, and security

• A
  3% (1)
• B
  3% (1)
• C
  8% (3)
• D
  88% (35)

Explanation

Option D captures the five universally recognized customer requirements for storage components: Performance (speed and throughput), Cost (acquisition and operational), Capacity (how much data can be stored), Reliability (uptime and data integrity), and Security (protection from unauthorized access). These five pillars appear consistently across vendor certifications (CompTIA, EMC, NetApp) as the foundational framework for evaluating storage solutions.

Why the distractors fail:

• A is incomplete (only lists four items) and swaps in "Return on Investment" and "expandability," which are business metrics rather than core customer requirements.
• B introduces vague terms like "ecology" and "efficiency" that don't belong to standard storage evaluation frameworks.
• C includes "accuracy" and "readability," which are data quality concepts, not storage component requirements.

Memory tip: Use the acronym "PC² RS" - Performance, Cost, Capacity, Reliability, Security - or think of it as what every storage buyer asks: "How fast, how cheap, how much, how dependable, and how safe?"
