Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 739 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 739
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company is building a new application that uses serverless architecture. The architecture will consist of an Amazon API Gateway REST API and AWS Lambda functions to manage incoming requests.

The company wants to add a service that can send messages received from the API Gateway REST API to multiple target Lambda functions for processing. The service must offer message filtering that gives the target Lambda functions the ability to receive only the messages the functions need.

Which solution will meet these requirements with the LEAST operational overhead?

  • A. Send the requests from the API Gateway REST API to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe Amazon Simple Queue Service (Amazon SQS) queues to the SNS topic. Configure the target Lambda functions to poll the different SQS queues.
  • B. Send the requests from the API Gateway REST API to Amazon EventBridge. Configure EventBridge to invoke the target Lambda functions.
  • C. Send the requests from the API Gateway REST API to Amazon Managed Streaming for Apache Kafka (Amazon MSK). Configure Amazon MSK to publish the messages to the target Lambda functions.
  • D. Send the requests from the API Gateway REST API to multiple Amazon Simple Queue Service (Amazon SQS) queues. Configure the target Lambda functions to poll the different SQS queues.

The main issue with B is that with Eventbrige, you can only define up to five targets for each rule. https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-targets.html

B: EventBridge reacts to events, not requests or messages. C: I don't think so, but I don't know MSK well enough. D: You can add a filter so that your function only processes Amazon SQS messages containing certain data parameters. but it will still receive, so I assume it's not what the question asks for. Only A remains... But it still misses steps plus we are looking for the Least ops overhead.. I am confused..

Eventbridge + lambda is two services, sns + sqs + lambda is 3. Both can filter, but the config involved in eventbridge > lambda is easier

SNS provides built-in message filtering. SNS -> SQS -> Lambda = very common Fanout Scenario

Selected Answer: D
Upload and store content in Amazon S3 in the Region that is closest to the user. Use multiple distributions of Amazon CloudFront. This approach ensures that uploads are quick, taking advantage of the geographical proximity of S3, while still leveraging CloudFront for efficient content delivery outside the local region if necessary. The local nature of the content consumption aligns with storing content in the closest region to the user, addressing the requirement that 90% of the content is consumed within the AWS Region where it is uploaded.

I'd go with D Multiple targets but target Lambda functions the ability to receive only the messages the functions need, so gateway should send to specific SQS so specific lambda can process that message. With SNS you send to all at once, so lambdas will get the messages they can't process. Correct me if I'm wrong.

Selected Answer: B
to multiple target = SNS, EventBridge. Also, SNS has to use SQS to send filtered content, and Lambda has to poll the SQS to get the message, which is clearly an Overhead. Meanwhile, EventBridge can invoke a Lambda function, which reduces the Operational Overhead.
