AWS Certified Cloud Practitioner — Question 619

A user needs the ability to access as many resources as are needed. The user also needs the ability to scale up and scale down with only a few minutes of notice.

Which benefit of the AWS Cloud describes these abilities?

Answer options

• A. Reliability
• B. Economy of scale
• C. Elasticity
• D. Pay-as-you-go pricing

Correct answer: C

Explanation

Elasticity is the ability to acquire resources when you need them and release them when you don't, allowing systems to scale up and down rapidly to meet demand. Reliability refers to a system's ability to recover from service disruptions, while economies of scale and pay-as-you-go pricing relate to cost optimization rather than dynamic resource scaling.
