Which combination of steps should the solutions architect take to meet these requirements?

Explanations:

Creating an SNS topic and subscribing a mailing list to it is the standard way to send notifications to a group of people. This sets up the notification channel.

Creating a “Email” task that publishes to the SNS topic connects the Step Function workflow to the notification channel. This task will be executed when a failure is caught.

TheCatchfield in Step Functions is used to handle errors. Setting”ErrorEquals”: [ “States.ALL” ]ensures thatalltypes of errors are caught, fulfilling the requirement to be notified ofallfailures. The”Next”: “Email”part specifies that the “Email” task (which sends the notification) should be executed if an error is caught.

While SES can be used for sending emails, it’s not the most straightforward approach for Step Functions. SNS is better integrated with Step Functions for notifications. This adds unnecessary complexity.

Similar to D, using SES directly from Step Functions is more complex than using SNS. Step Functions has a direct integration with SNS for notifications. Using SES would require custom Lambda functions or other integrations.

“States.Runtime”only catches runtime errors. It does not catch other types of errors, such asStates.TaskFailed,States.Timeout, or custom errors. The requirement is to be notified ofallfailures, so”States.ALL”is required.
