Correct answer - "SNS Messages can be retrieved at a later date" : Amazon Simple Notification
Service (SNS) is a highly available, durable, secure, fully managed pub/sub messaging service
that enables you to decouple microservices, distributed systems, and serverless applications.
Amazon SNS provides topics for high-throughput, push-based, many-to-many messaging. Using Amazon
SNS topics, your publisher systems can fan out messages to a large number of subscriber
endpoints for parallel processing, including Amazon SQS queues, AWS Lambda functions, and HTTP/S
webhooks. Additionally, SNS can be used to fan out notifications to end users using mobile push,
SMS, and email.
Incorrect:
"Messages are sent to all subscribers" - SNS topics can have subscribers from any supported push
notifications platform, as well as any other endpoint type such as SMS or email.
"Lambda can be a target of SNS" - When a message is published to an Amazon SNS topic, the service
can invoke your Lambda function by passing the message payload as a parameter
"SQS can be a target of SNS" - An Amazon SNS message can be sent to a topic and then replicated
and pushed to multiple Amazon SQS queues
