A Solutions Architect is designing a web application that uses Amazon CloudFront, an Elastic Load Balancing Application Load Balancer, and an Auto Scaling group of Amazon EC2 instances. The load balancer and EC2 instances are in the US West (Oregon) region. It has been decided that encryption in transit is necessary by using a customer-branded domain name from the client to CloudFront and from CloudFront to the load balancer. Assuming that AWS Certificate Manager is used, how many certificates will need to be generated?

A.
One in the US West (Oregon) region and one in the US East (Virginia) region.
Answers
A.
One in the US West (Oregon) region and one in the US East (Virginia) region.

Answers
D.
Two in the US East (Virginia) region and none in the US West (Oregon) region.
Suggested answer: A

Explanation:

Why? If you want to require HTTPS between viewers and CloudFront, you must change the AWSRegion to US East (N. Virginia) in the AWS Certificate Manager console before you request or importa certificate. If you want to require HTTPS between CloudFront and your origin, and you're using anELB load balancer as your origin, you can request or import a certificate in any Region. https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cnames-and-httpsrequirements.html
