Your company is planning to use the API Gateway service to manage APIs for developers and users. There is a requirement to segregate access rights for both developers and users. How could this be accomplished?

Answer options:

A.Use IAM permissions to control the access.
B.Use AWS Access keys to manage the access.
C.Use AWS KMS service to manage the access.
D.Use AWS Config Service to control the access.

Correct Answer - A
AWS Documentation mentions the following.
You can control access to Amazon API Gateway with IAM permissions by controlling access to the following two API Gateway component processes.
To create, deploy, and manage an API in API Gateway, you must grant the API developer permissions to perform the required actions supported by the API management component of API Gateway.
To call a deployed API or to refresh the API caching, you must grant the API caller permissions to perform required IAM actions supported by the API execution component of API Gateway.
