Exam AWS Certified Solutions Architect - Professional topic 1 question 610 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 610
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company has an internal application running on AWS that is used to track and process shipments in the company's warehouse. Currently, after the system receives an order, it emails the staff the information needed to ship a package. Once the package is shipped, the staff replies to the email and the order is marked as shipped.
The company wants to stop using email in the application and move to a serverless application model.
Which architecture solution meets these requirements?

  • A. Use AWS Batch to configure the different tasks required to ship a package. Have AWS Batch trigger an AWS Lambda function that creates and prints a shipping label. Once that label is scanned, as it leaves the warehouse, have another Lambda function move the process to the next step in the AWS Batch job.
  • B. When a new order is created, store the order information in Amazon SQS. Have AWS Lambda check the queue every 5 minutes and process any needed work. When an order needs to be shipped, have Lambda print the label in the warehouse. Once the label has been scanned, as it leaves the warehouse, have an Amazon EC2 instance update Amazon SQS.
  • C. Update the application to store new order information in Amazon DynamoDB. When a new order is created, trigger an AWS Step Functions workflow, mark the orders as ג€in progressג€, and print a package label to the warehouse. Once the label has been scanned and fulfilled, the application will trigger an AWS Lambda function that will mark the order as shipped and complete the workflow.
  • D. Store new order information in Amazon EFS. Have instances pull the new information from the NFS and send that information to printers in the warehouse. Once the label has been scanned, as it leaves the warehouse, have Amazon API Gateway call the instances to remove the order information from Amazon EFS.

I go for C. Use DynamoDB Streams to trigger lambda then trigger step function.

Yes. AWS Batch is ruled out as it supports only EC2/Fargate based compute not lambdas.

"Once that label is scanned, as it leaves the warehouse, have another Lambda function move the process to the next step in the AWS Batch job". How do you propose to invoke the Lambda? Most appropriate option is C (Step Functions)
