Question

A company uses Amazon API Gateway to expose a set of APIs to customers. The APIs have caching enabled in API Gateway. Customers need a way to invalidate the cache for each API when they test the API. What should a developer do to give customers the ability to invalidate the API cache?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Attach an InvalidateCache policy to the IAM execution role that the customers use to invoke the API. Ask the customers to send a request that contains the Cache-Control:max-age=0 HTTP header when they make an API call. AWS IAM controls authenticated and authorized access to AWS resources with fine-grained policies.
