An architecture uses Amazon API Gateway and AWS Lambda. The APIs must be protected by mutual TLS (mTLS). How should the architect implement mTLS?

Answer options:

Configure mTLS directly on the Lambda function.

Configure mTLS on a custom domain name in API Gateway. Upload the client certificate trust store to Amazon S3.

Use AWS WAF to enforce mTLS on the API Gateway.

Deploy an Application Load Balancer in front of API Gateway to handle mTLS.

How to approach this question

Identify the native mTLS capability of API Gateway.

Full Answer

Amazon API Gateway natively supports mutual TLS (mTLS) authentication. You must use a custom domain name and provide a trust store (uploaded to S3) containing the certificates of trusted clients.

Common mistakes
