When designing a solution on ECS for a mobile backend, which of the following are critical hardware requirements?

Question

Options

• AHigh-performance CPUs for compute-intensive tasks
• BDecorative LED lighting for server cabinets
• CFast SSDs for quick data retrieval
• DRobust network infrastructure for handling peak loads

• A
  89% (42)
• B
  11% (5)

Explanation

Designing a mobile backend on ECS demands real hardware muscle: high-performance CPUs (A) handle compute-intensive workloads like image processing, authentication logic, and concurrent request handling that mobile apps constantly generate. Fast SSDs (C) are essential because mobile users expect near-instant responses - slow disk I/O directly translates to poor app experience and abandoned sessions. Robust network infrastructure (D) is non-negotiable since mobile backends must absorb unpredictable traffic spikes (viral moments, flash sales) without degradation. Option B is wrong because decorative LED lighting is purely cosmetic and has zero impact on system performance, reliability, or scalability - it's a nonsense distractor.

Memory tip: Think "CNS" - CPU, Network, Storage - the three pillars of any backend that serves real users at scale. If it doesn't affect speed, throughput, or capacity, it doesn't belong on your hardware requirements list.
