Which action can help the company achieve this goal?
Enable API caching in API Gateway.
Configure API Gateway to use an interface VPC endpoint
Enable cross-origin resource sharing (CORS) for the APIs.
Configure usage plans and API keys in API Gateway.
Explanations:
Enabling API caching in API Gateway will cache responses to common requests, reducing the time required for frequent, repeated requests and improving overall responsiveness.
Configuring an interface VPC endpoint is useful for private API communication but does not improve the responsiveness of the APIs for public, unauthenticated access.
Enabling cross-origin resource sharing (CORS) is necessary for enabling browser-based requests from different domains, but it does not enhance the responsiveness of APIs.
Configuring usage plans and API keys is used for rate-limiting and throttling API usage but does not directly improve the responsiveness of APIs.
