Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

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.)

  • A. Register the required domain in a registrar. Create a wildcard custom domain name in a Route 53 hosted zone and record in the zone that points to the API Gateway endpoint.
  • B. Request a wildcard certificate that matches the domains in AWS Certificate Manager (ACM) in a different Region.
  • C. Create hosted zones for each customer as required in Route 53. Create zone records that point to the API Gateway endpoint.
  • D. Request a wildcard certificate that matches the custom domain name in AWS Certificate Manager (ACM) in the same Region.
  • E. Create multiple API endpoints for each customer in API Gateway.
  • F. Create a custom domain name in API Gateway for the REST API. Import the certificate from AWS Certificate Manager (ACM).

Step A involves registering the required domain in a registrar and creating a wildcard custom domain name in a Route 53 hosted zone. This allows you to map individual and secure URLs for all customers to your API Gateway endpoints. Step D is to request a wildcard certificate from AWS Certificate Manager (ACM) that matches the custom domain name you created in Step A. This wildcard certificate will cover all subdomains and ensure secure HTTPS communication. Step F is to create a custom domain name in API Gateway for your REST API. This allows you to associate the custom domain name with your API Gateway endpoints and import the certificate from ACM for secure communication.

The key points: Using a wildcard domain and certificate avoids managing individual domains/certs per customer. This is more efficient. The domain, hosted zone, and certificate should all be in the same region as the API Gateway REST API for simplicity. Creating multiple API endpoints per customer (Option E) adds complexity and is not required. Option B and C add unnecessary complexity by separating domains, certificates, and hosted zones.

ADF looks right but not sure why C is wrong: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-to-api-gateway.html#routing-to-api-gateway-config

My guess on why C is not ideal: Creating individual hosted zones for each customer is too much. It definitely increases operational overhead, while using a wildcard domain eliminates this need (which is more ideal).
