Which solution will meet these requirements?
Create a certificate in ACM in any one of the Regions. Import the certificate into the ALB that is in each Region.
Create a global certificate in ACM. Update the CloudFormation template to deploy the global certificate to each ALB.
Create a certificate in ACM in each Region. Import the certificate into the ALB for each Region.
Create a certificate in ACM in the us-east-1 Region. Update the CloudFormation template to deploy the certificate to each ALB.
Explanations:
ACM certificates are region-specific, and importing a certificate from one region to another is not supported. Each ALB requires a certificate that is issued in the same region.
ACM does not support global certificates; certificates must be created and managed in each specific region where they will be used. There is no feature for deploying a single certificate globally across multiple regions.
Each AWS Region requires its own ACM certificate. Therefore, creating a separate certificate in ACM for each region and associating it with the corresponding ALB is the correct approach.
ACM certificates are region-specific, and a certificate created in the us-east-1 region cannot be used in ALBs located in other regions. Each ALB must have its own certificate created in the same region.
If I’m correct, the answer is:
Create a certificate in ACM in each Region. Import the certificate into the ALB for each Region.
It appears that the answer is:
Create a certificate in ACM in each Region. Import the certificate into the ALB for each Region.
