AWS Certified Cloud Practitioner — Question 820

Which scenarios represent the concept of elasticity on AWS? (Choose two.)

Answer options

• A. Scaling the number of Amazon EC2 instances based on traffic
• B. Resizing Amazon RDS instances as business needs change
• C. Automatically directing traffic to less-utilized Amazon EC2 instances
• D. Using AWS compliance documents to accelerate the compliance process
• E. Having the ability to create and govern environments using code

Correct answer: A, B

Explanation

Elasticity in AWS refers to the capability to scale resources dynamically to match demand, whether by scaling out/in or scaling up/down. Adjusting the quantity of Amazon EC2 instances and resizing Amazon RDS instances to fit changing business needs are direct examples of this elasticity. The other options describe load balancing, compliance auditing, and infrastructure as code, which do not represent elasticity.
