AWS Certified Cloud Practitioner — Question 29

Which AWS service can be used to decouple applications?

Answer options

• A. AWS Config
• B. Amazon Simple Queue Service (Amazon SQS)
• C. AWS Batch
• D. Amazon Simple Email Service (Amazon SES)

Correct answer: B

Explanation

Amazon Simple Queue Service (Amazon SQS) is designed to decouple application components by enabling asynchronous message queuing, which allows different parts of an application to communicate without being directly connected. AWS Config is used for resource monitoring, AWS Batch is for batch processing jobs, and Amazon SES is an email service, none of which serve the purpose of decoupling applications.
