[All AWS Certified Security - Specialty Questions]

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.
  • B. Two in the US West (Oregon) region and none in the US East (Virginia) region.
  • C. One in the US West (Oregon) region and none in the US East (Virginia) region.
  • D. Two in the US East (Virginia) region and none in the US West (Oregon) region.

A is ineed the answer but the reasoning for ELB certs from ACM is wrong....you can't request a cert for ELB from any region but the region where your ELB needs to support a FQDN/customer specific url than a generic CDN url- see here- https://docs.aws.amazon.com/acm/latest/userguide/acm-overview.html

A - is correct. AWS Region for AWS Certificate Manager To use a certificate in AWS Certificate Manager (ACM) to require HTTPS between viewers and CloudFront, make sure you request (or import) the certificate in the US East (N. Virginia) Region (us-east-1). If you want to require HTTPS between CloudFront and your origin, and you’re using a load balancer in Elastic Load Balancing as your origin, you can request or import the certificate in any AWS Region.

It's more about history/physical infrastructure of AWS, than geography. us-east1 is where it all started and hence any global resource is hosted there, all new services start there.

Answer: A Why? If you want to require HTTPS between viewers and CloudFront, you must change the AWS Region to US East (N. Virginia) in the AWS Certificate Manager console before you request or import a certificate. If you want to require HTTPS between CloudFront and your origin, and you're using an ELB 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-https-requirements.html
