AWS Certified Cloud Practitioner — Question 825

Which AWS services can a company use to achieve a loosely coupled architecture? (Choose two.)

Answer options

• A. Amazon Workspaces
• B. Amazon Simple Queue Service (Amazon SQS)
• C. Amazon Connect
• D. AWS Trusted Advisor
• E. AWS Step Functions

Correct answer: B, E

Explanation

Amazon SQS enables loose coupling by allowing different components of an application to send, store, and receive messages asynchronously without dependencies on each other. AWS Step Functions orchestrates distributed components and microservices into workflows, which decouples the application logic from the individual services. Other options like Amazon WorkSpaces, Amazon Connect, and AWS Trusted Advisor do not contribute to decoupling application architectures.
