A company has automated the nightly retraining ot its machine learning models by using AWS Step Functions. The workflow consists of multiple steps that use AWS Lambda. Each step can fail for various reasons, and any failure causes a failure of the overall workflow.
A review reveals that the retraining has failed multiple nights in a row without the company noticing the failure. A solutions architect needs to improve the workflow so that notifications are sent for all types of failures in the retraining process.
Which combination of steps should the solutions architect take to meet these requirements? (Select THREE.)

1. A. Create an Amazon Simple Notification Service {Amazon SNS) topic with a subscription of type"Email" that targets the team's mailing list.
2. B. Create a task named "Email" that forwards the input arguments to the SNS topic
3. C. Add a Catch field to all Tas
4. D. Ma
5. E. and Parallel states that have a statement of "ErrorEquals": [ "states.all" ] and "Next": "Email".
6. F. Add a new email address to Amazon Simple Email Service (Amazon SES). Verify the email address.
7. G. Create a task named "Email" that forwards the input arguments to the SES email address
8. H. Add a Catch field to all Task, Map, and Parallel states that have a statement of "ErrorEquals": [ "states.Bun time" ] and "Next": "Email".

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?

1. A. Use AWS Batch to configure the different tasks required lo ship a packag
2. B. Have AWS Batch trigger an AWS Lambda function that creates and prints a shipping labe
3. C. Once that label is scanne
4. D. as it leaves the warehouse, have another Lambda function move the process to the next step in the AWS Batch job.B.
5. E. When a new order is created, store the order information in Amazon SQ
6. F. Have AWS Lambda check the queue every 5 minutes and process any needed wor
7. G. When an order needs to be shipped, have Lambda print the label in the warehous
8. H. Once the label has been scanned, as it leaves the warehouse, have an Amazon EC2 instance update Amazon SOS.
9. I. Update the application to store new order information in Amazon DynamoD
10. J. When a new order is created, trigger an AWS Step Functions workflow, mark the orders as "in progress," and print a package label to the warehous
11. K. 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.
12. L. Store new order information in Amazon EF
13. M. Have instances pull the new information from the NFS and send that information to printers in the warehous
14. N. 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.
