AWS Certified Cloud Practitioner (CLF-C02) — Question 122

A company has a set of ecommerce applications. The applications need to be able to send messages to each other.
Which AWS service meets this requirement?

Answer options

• A. AWS Auto Scaling
• B. Elastic Load Balancing
• C. Amazon Simple Queue Service (Amazon SQS)
• D. Amazon Kinesis Data Streams

Correct answer: C

Explanation

Amazon Simple Queue Service (Amazon SQS) is designed specifically for message queuing between distributed applications, making it the ideal choice for this requirement. AWS Auto Scaling and Elastic Load Balancing do not provide messaging capabilities, while Amazon Kinesis Data Streams is primarily used for real-time data streaming rather than message queuing.
