Question

You have an Azure API Management (APIM) Standard tier instance named APIM1 that uses a managed gateway. You plan to use APIM1 to publish an API named API1 that uses a backend database that supports only a limited volume of requests per minute. You also need a policy for API1 that will minimize the possibility that the number of requests to the backend database from an individual IP address you specify exceeds the supported limit. You need to identify a policy for API1 that will meet the requirements. Which policy should you use?
