AWS Certified SysOps Administrator – Associate (legacy) — Question 235

A user has developed an application which is required to send the data to a NoSQL database. The user wants to decouple the data sending such that the application keeps processing and sending data but does not wait for an acknowledgement of DB. Which of the below mentioned applications helps in this scenario?

Answer options

• A. AWS Simple Notification Service
• B. AWS Simple Workflow
• C. AWS Simple Queue Service
• D. AWS Simple Query Service

Correct answer: C

Explanation

AWS Simple Queue Service (SQS) is designed for decoupling components of applications, allowing data to be sent without waiting for processing acknowledgment. The other options, like AWS Simple Notification Service and AWS Simple Workflow, do not provide the same queuing mechanism, while AWS Simple Query Service is not relevant to this use case.
