AWS Certified SysOps Administrator – Associate (legacy) — Question 469

Elasticity is one of the benefits of using Elastic Beanstalk. Which of the following best describes the concept of elasticity?

Answer options

• A. It is the ability for counting the number of architectural design considerations that are required to develop a console.
• B. It is the streamlining of resource acquisition and release, so that your infrastructure can rapidly scale in and scale out as demand fluctuates.
• C. It is the process of examining the amount of security credentials required to access a data vol-ume.
• D. It is the procedure of estimating the resource cost, so that you can run a specific project on AWS.

Correct answer: B

Explanation

Elasticity refers to the ability to automatically scale computing resources up or down (in or out) to match the current demand, ensuring optimal performance and cost-efficiency. Option B accurately describes this dynamic scaling mechanism, which is a core feature of AWS Elastic Beanstalk. Options A, C, and D describe irrelevant concepts such as architectural counting, security credential evaluation, and cost estimation, none of which define elasticity.
