A company has a workload in an AWS Region. Customers connect to and access the workload by using an Amazon API Gateway REST API. The company uses Amazon Route 53 as its DNS provider. The company wants to provide individual and secure URLs for all customers. Which combination of steps will meet these requirements with the MOST operational efficiency? (Choose three.)

To provide individual and secure URLs efficiently, you need a custom domain and SSL/TLS encryption. Registering a domain and creating a wildcard custom domain in Route 53 (e.g., .yourcompany.com) allows for unique subdomains for each customer without creating separate records for every single one, which is operationally efficient. Requesting a wildcard certificate in ACM in the same region as API Gateway is crucial because ACM certificates are region-specific and required for custom domains. Finally, creating a custom domain name in API Gateway and associating it with the ACM certificate enables API Gateway to serve traffic securely over your custom domain. Creating multiple API endpoints or individual hosted zones for each customer would be less operationally efficient. Requesting a certificate in a different region would not work.
