Q7 Single choice

A company uses Amazon CloudFront to serve a static application from an Amazon S3 bucket origin. A custom domain maps to the CloudFront distribution. The application calls an Amazon API Gateway Regional API endpoint in the ap-northeast-1 Region for backend APIs. The company configures cross-origin resource sharing (CORS) so the application can access the APIs. Tests find that API calls are slower from outside ap-northeast-1, which causes slow performance.
The company must improve the performance of the application.

Which solution will meet this requirement?

A
Enable CloudFront Origin Shield and S3 Transfer Acceleration for the S3 bucket.
B
Use an Amazon Route 53 latency-based routing policy for the Regional API endpoint and the CloudFront distribution.
C
Set the Regional API endpoint as an origin for the CloudFront distribution. Access the backend APIs by using the application's DNS name.
D
Set up AWS Global Accelerator in the same account that hosts the CloudFront distribution. Access the backend APIs by using Global Accelerator.
