A customer needs an entry-level object storage archive solution. They need 500 TB of capacity and are projecting 10% data growth in the next five years. They have limited space at their data center…

Question

Options

• AEX5000S
• BEX5000D
• CEX500
• DEXF900

• A
  4% (1)
• B
  11% (3)
• C
  82% (23)
• D
  4% (1)

Explanation

EX500 (C) is IBM's entry-level object storage node designed specifically for archive workloads. It provides high-density capacity in a compact form factor - critical when data center space is constrained - and is appropriately sized to meet the 500 TB baseline while accommodating ~61% projected growth over five years (10% compounded annually).

Why the distractors are wrong:

• EX5000S and EX5000D (A & B) are higher-tier, larger-footprint nodes built for greater scale and throughput demands - overkill for an entry-level requirement and consuming more rack space than the customer can spare.
• EXF900 (D) is a flash-based node optimized for high-performance, low-latency workloads; flash storage carries a significant cost premium that is unnecessary and inefficient for archive use cases.

Memory tip: Use the naming conventions as clues - "EXF900" → F = Flash = fast/performance (not archive); "EX5000" → large number = large scale (not entry-level). The smallest model number, EX500, maps to the smallest/entry-level need.
