Question

Difficulty: MediumDefine the benefits of the AWS Cloud

A digital health startup is launching a telemedicine application. The startup wants to pay for computing resources only when the application is actively running, rather than investing in physical servers upfront. Additionally, the developers want the infrastructure to scale up or down automatically in response to daily patient traffic fluctuations, avoiding the need to predict peak capacity.

Which two benefits of the AWS Cloud directly align with the startup's requirements? (Select TWO.)

  1. Trade fixed expense for variable expenseAnswer
  2. Stop guessing capacityAnswer
  3. C
    Trade variable expense for fixed expense
  4. D
    Pre-provision maximum capacity to ensure high availability during peak hours
  5. E
    Benefit from massive economies of scale

Answer

Trading fixed expense for variable expense and stopping guessing capacity are the correct answers.
The startup's goal to pay only for active resources instead of physical servers represents the benefit of trading fixed expense for variable expense. The goal to scale resources automatically based on traffic without predicting peak capacity represents the benefit of stopping guessing capacity.

Step-by-Step Solution

1
Analyze the first requirement: pay for resources only when active rather than buying physical servers upfront.
This matches the benefit 'Trade fixed expense for variable expense' because it shifts spending from capital expenses (fixed servers) to operational expenses (variable usage).
Identify the economic benefit described in the scenario.
2
Analyze the second requirement: automatically scale capacity up or down to match traffic fluctuations without predicting peak capacity.
This matches the benefit 'Stop guessing capacity' by leveraging elasticity to scale dynamically based on demand rather than over-provisioning.
Identify the operational benefit described in the scenario.
