AWS Certified Cloud Practitioner (CLF-C02) — Question 151
A company wants to automatically add and remove Amazon EC2 instances. The company wants the EC2 instances to adjust to varying workloads dynamically.
Which service or feature will meet these requirements?
Answer options
- A. Amazon DynamoDB
- B. Amazon EC2 Spot Instances
- C. AWS Snow Family
- D. Amazon EC2 Auto Scaling
Correct answer: D
Explanation
Amazon EC2 Auto Scaling is designed to automatically adjust the number of EC2 instances based on workload demands, making it the ideal choice for this scenario. The other options do not provide the same capability for dynamic scaling of instances; for instance, DynamoDB is a database service, Spot Instances are a pricing model for EC2, and AWS Snow Family is for data transfer solutions.
