Question

As a developer, you have been told to create an API gateway stage that will directly interact with DynamoDB tables.

Which of the following feature of the API Gateway must be used to fulfill this requirement?

A. Ensure to create an Integration request.

B. Ensure to enable CORS.

C. Ensure to enable DAX.

D. Enable Binary payloads.

Answer 1

Answer - A.

This is also mentioned in the AWS Documentation.

For example, with DynamoDB as the backend, the API developer sets up the integration request to forward the incoming method request to the chosen backend.

The setup includes specifications of an appropriate DynamoDB action, required IAM role and policies, and required input data transformation.

The backend returns the result to API Gateway as an integration response.

To route the integration response to an appropriate method response (of a given HTTP status code) to the client, you can configure the integration response to map required response parameters from integration to method.

Option B is incorrect since this is only required for cross-domain requests.

Option C is incorrect since this is only required for low latency to DynamoDB tables.

Option D is incorrect since this is only required if the request is not text-based.
