Example question from this objective
Each option is explained, so the reasoning behind the distractors is part of the answer.
An AppSync GraphQL API needs to resolve one field from DynamoDB and another field by invoking custom business logic. Which AppSync design element should the developer configure?
- An EC2 Auto Scaling launch template only
- Data sources for DynamoDB and Lambda resolvers
- An S3 lifecycle rule for GraphQL requests
- A CloudWatch dashboard without resolvers
An EC2 Auto Scaling launch template only — A launch template supports EC2 scaling and does not resolve GraphQL fields.
Data sources for DynamoDB and Lambda resolvers — AppSync resolvers connect GraphQL fields to data sources such as DynamoDB tables and Lambda functions.
An S3 lifecycle rule for GraphQL requests — S3 lifecycle rules manage object retention and do not process GraphQL requests.
A CloudWatch dashboard without resolvers — Dashboards can visualize metrics but cannot provide resolver logic for an API.
