Exam AWS Certified Cloud Practitioner CLF-C02 topic 1 question 140 discussion

A: Amazon WorkSpaces is a managed desktop service B: Amazon Simple Queue Service (Amazon SQS) allows components of a system to communicate asynchronously C: Amazon Connect is a cloud-based contact center service D: AWS Trusted Advisor provides recommendations for optimizing AWS environments E: AWS Step Functions AWS Step Functions is a service that helps you coordinate multiple AWS services

B. Amazon Simple Queue Service (Amazon SQS) E. AWS Step Functions

Amazon Connect is not correct because it is a cloud-based contact center service that helps businesses provide superior customer service at a lower cost. Amazon Workspaces is a desktop virtualization service.

Exam Topics got it wrong again... Here’s how these services contribute to a loosely coupled architecture: B. Amazon Simple Queue Service (Amazon SQS): Amazon SQS is a fully managed message queuing service that enables asynchronous communication between distributed components of an application. By decoupling the components of your system, SQS helps ensure that different parts of your architecture can operate independently and communicate without being directly connected. This decoupling allows for greater scalability and fault tolerance. E. AWS Step Functions: AWS Step Functions is a serverless orchestration service that enables you to coordinate multiple AWS services into serverless workflows. It allows you to build and manage workflows that integrate different services, and each step in the workflow can be independently developed and scaled. This service helps in creating loosely coupled components by managing the sequence of service calls and ensuring that each component performs its task independently.

For achieving a loosely coupled architecture, a company can use the following AWS services: Amazon Simple Queue Service (Amazon SQS) AWS Step Functions

B.Amazon Simple Queue Service (Amazon SQS): SQS is a fully managed message queuing service that allows components of a distributed application to communicate asynchronously. It helps decouple the sender and receiver components, providing flexibility and fault tolerance. E. AWS Step Functions: AWS Step Functions allow you to coordinate and sequence AWS services, including Lambda functions, in a serverless workflow. It helps in creating workflows that are scalable, resilient, and loosely coupled.

To achieve a loosely coupled architecture, services that enable asynchronous communication and decouple components are essential. Two services that support this goal are: B. Amazon Simple Queue Service (Amazon SQS): SQS is a fully managed message queuing service that allows components of a distributed application to communicate asynchronously. It helps decouple the sender and receiver components, providing flexibility and fault tolerance. E. AWS Step Functions: AWS Step Functions allow you to coordinate and sequence AWS services, including Lambda functions, in a serverless workflow. It helps in creating workflows that are scalable, resilient, and loosely coupled. While options A, C, and D (Amazon WorkSpaces, Amazon Connect, and AWS Trusted Advisor) are useful in various scenarios, they do not specifically contribute to achieving a loosely coupled architecture as directly as SQS and Step Functions.

B and E are correct

**B. Amazon Simple Queue Service (Amazon SQS):** SQS is a fully managed message queuing service that enables decoupling of the components in a distributed system. It allows components to communicate asynchronously, promoting loose coupling. **E. AWS Step Functions:** Step Functions is a serverless function orchestrator that allows you to coordinate multiple AWS services into serverless workflows. It helps in creating loosely coupled, flexible systems by defining workflows that connect various services. So, the correct choices are B and E.
