Example question from this objective
Each option is explained, so the reasoning behind the distractors is part of the answer.
A development team wants to run custom validation before a new Amazon Cognito user is confirmed and then publish a welcome event after confirmation. Which mechanism should be used?
- Cognito user pool Lambda triggers
- S3 Transfer Acceleration
- CloudWatch metric math
- DynamoDB adaptive capacity
Cognito user pool Lambda triggers — Cognito user pools can invoke Lambda triggers at workflow points such as pre sign-up and post confirmation.
S3 Transfer Acceleration — Transfer Acceleration improves S3 transfer paths and does not run authentication workflow code.
CloudWatch metric math — Metric math combines CloudWatch metrics and does not customize user pool lifecycle events.
DynamoDB adaptive capacity — Adaptive capacity helps DynamoDB handle uneven traffic and does not customize Cognito user workflows.
