Question 60
A team considers the following AWS use case: A notification system must publish one event to several subscribed recipients using supported delivery endpoints. Which limitation remains relevant?
Explanation
Correct Answer
SNS fan-out is not a replacement for a persistent work queue in every use case. This is the best important qualification for the stated situation. Amazon SNS offers publish-subscribe messaging and fan-out notifications. The key business clue is: Look for a producer sending one message to multiple subscribers. A suitable choice is: Publish the event to an SNS topic with approved subscriptions. An expected result is: Configured subscribers receive the expected notification through supported endpoints. Important limitation: SNS fan-out is not a replacement for a persistent work queue in every use case.
Incorrect Answers
Amazon Simple Email Service supports application email sending and related email workloads. That addresses a different mechanism; this question turns on SNS fan-out is not a replacement for a persistent.
AWS Step Functions orchestrates workflows with defined states and transitions. That observation may hold without resolving the relevant issue: SNS fan-out is not a replacement for a persistent.
Amazon EventBridge provides event buses and event-pattern-based routing. This is different from the required SNS fan-out is not a replacement for a persistent result.
