Which statements represent the cost-effectiveness of the AWS Cloud? (Choose two.)

Question

Options

• AUsers can trade fixed expenses for variable expenses.
• BUsers can deploy all over the world in minutes.
• CAWS offers increased speed and agility.
• DAWS is responsible for patching the infrastructure.
• EUsers benefit from economies of scale.

• A
  93% (50)
• B
  4% (2)
• C
  2% (1)
• D
  2% (1)

Explanation

A (trade fixed for variable expenses) is correct because instead of paying upfront for data centers and servers you may not fully use, you only pay for what you consume - a direct cost model shift. E (economies of scale) is correct because AWS aggregates usage from hundreds of thousands of customers, passing those bulk purchasing savings on to users in the form of lower pay-as-you-go prices.

Why the distractors are wrong:

• B (deploy globally in minutes) is a benefit of AWS, but it describes agility/speed, not cost-effectiveness.
• C (increased speed and agility) similarly describes operational benefits, not financial savings.
• D (AWS patches infrastructure) describes the shared responsibility model, which is a security/operational concept, not a cost benefit.

Memory tip: Filter your answers by asking "Does this save money or change how I pay?" - only A and E pass that test. Think of the AWS cost-effectiveness pillars as "Variable + Volume": variable pricing (A) and volume discounts via economies of scale (E).
