Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Simple Queue Service (SQS)
Amazon SQS (Option A), Amazon SNS (Option B), and Amazon EventBridge (Option E) are correct because they all enable asynchronous messaging and event-driven decoupling between application components. SQS provides message queues for decoupling producers and consumers, SNS supports pub/sub messaging, and EventBridge routes events from various sources. AWS Step Functions (Option C) is designed for orchestrating workflows, not primarily for decoupling. Amazon Kinesis Data Streams (Option D) is used for real-time streaming analytics, not general decoupling.
