Which design principles should a company apply to AWS Cloud workloads to maximize sustainability and minimize environmental impact? (Choose two.)

Question

Options

• AMaximize utilization of Amazon EC2 instances.
• BMinimize utilization of Amazon EC2 instances.
• CMinimize usage of managed services.
• DForce frequent application reinstallations by users.
• EReduce the need for users to reinstall applications.

• A
  86% (25)
• B
  7% (2)
• C
  3% (1)
• D
  3% (1)

Explanation

Sustainability in AWS Cloud Design

Maximizing EC2 instance utilization (A) reduces the number of servers needed, meaning less hardware consumption, less energy use, and a smaller carbon footprint - doing more with less is a core sustainability principle. Reducing the need for users to reinstall applications (E) minimizes unnecessary data transfer, compute processing, and energy consumption associated with repeated downloads and installations.

Why the distractors are wrong:

• (B) Minimizing EC2 utilization means you need more instances to handle the same workload, which wastes resources and energy.
• (C) Managed services are more sustainable because AWS optimizes their infrastructure at scale; avoiding them forces you to manage less-efficient resources yourself.
• (D) Forcing frequent reinstallations does the opposite of sustainability - it generates unnecessary network traffic and compute load.

Memory Tip: Think of sustainability as "do more with less, and avoid waste." High utilization = fewer servers needed (less waste), and stable applications = fewer redundant downloads (less waste). If an answer choice forces more activity or less efficiency, it's almost certainly wrong for a sustainability question.
