AWS Certified Cloud Practitioner — Question 79

A company needs to simultaneously process hundreds of requests from different users.
Which combination of AWS services should the company use to build an operationally efficient solution?

Answer options

• A. Amazon Simple Queue Service (Amazon SQS) and AWS Lambda
• B. AWS Data Pipeline and Amazon EC2
• C. Amazon Kinesis and Amazon Athena
• D. AWS Amplify and AWS AppSync

Correct answer: A

Explanation

The correct answer is A because Amazon SQS is designed for decoupling and managing message queues, while AWS Lambda enables serverless execution of code in response to those messages, allowing for efficient handling of requests. The other options do not provide the same level of immediacy and scalability for processing multiple simultaneous user requests.
