Test your knowledge of Amazon Simple Queue Service (SQS)

Question 1

Your application processes sensitive healthcare data through Amazon SQS. Which of the following solutions would help you meet security and regulatory requirements for data at rest encryption in Amazon SQS?

Correct Answer: Enable server-side encryption (SSE) for the SQS queue

Server-side encryption (SSE) for Amazon SQS protects your sensitive data at rest by encrypting the body of a message in the queue. Client-side encryption, HTTPS, Amazon Cognito, and IAM policies do not address encryption for data at rest in Amazon SQS.

Question 2

A DevOps team is monitoring their applications using Amazon CloudWatch. They want to programmatically process each metric alarm that enters the 'ALARM' state. Which Amazon service should be used to deliver these events for processing?

Correct Answer: Amazon Simple Notification Service (SNS) with Amazon SQS

AWS CloudWatch Alarms can publish notifications to Amazon SNS, which can then be used to deliver messages to Amazon SQS for processing. The other options either do not support the integration with CloudWatch or are not suited for the desired use case.

Question 3

A company is using Amazon SQS to manage messages between microservices. They want to ensure that messages are delivered to consumers in the same order they were sent. Which type of SQS queue should they use?

Correct Answer: FIFO (First-In-First-Out) Queue

Amazon SQS offers two types of message queues: Standard and FIFO. A FIFO queue ensures that the order of messages is preserved, providing exactly-once processing and eliminating duplicates.
