Topic 1 Question 143
2 つ選択A weather service provides high-resolution weather maps from a web application hosted on AWS in the eu-west-1 Region. The weather maps are updated frequently and stored in Amazon S3 along with static HTML content. The web application is fronted by Amazon CloudFront.
The company recently expanded to serve users in the us-east-1 Region, and these new users report that viewing their respective weather maps is slow from time to time.
Which combination of steps will resolve the us-east-1 performance issues?
Configure the AWS Global Accelerator endpoint for the S3 bucket in eu-west-1. Configure endpoint groups for TCP ports 80 and 443 in us-east-1.
Create a new S3 bucket in us-east-1. Configure S3 cross-Region replication to synchronize from the S3 bucket in eu-west-1.
Use [email protected] to modify requests from North America to use the S3 Transfer Acceleration endpoint in us-east-1.
Use [email protected] to modify requests from North America to use the S3 bucket in us-east-1.
Configure the AWS Global Accelerator endpoint for us-east-1 as an origin on the CloudFront distribution. Use [email protected] to modify requests from North America to use the new origin.

A: Global Accelerator can't have an s3 bucket as endpoint C: People are complaining about time to retreive maps. Transfert acceleration is used to accelerate PUT requests to an s3 bucket located in a distant region. E: An accelerator as cloudfront origin does not make much sense, because cloudfront is already using the AWS network. Global Accelerator is usually for Layer 4 networking and/or static anycast IPs

B is correct because it involves creating a new S3 bucket in the us-east-1 region and configuring cross-Region replication to synchronize from the existing S3 bucket in eu-west-1. This will allow users in us-east-1 to access the weather maps from a closer location, improving performance.
D is correct because it involves using [email protected] to modify requests from North America to use the S3 bucket in us-east-1. This will also allow users in us-east-1 to access the weather maps from a closer location, improving performance.
A and E are not correct because they do not involve creating a new S3 bucket in us-east-1, which is necessary for improving performance for the users in that region. C is not correct because it involves using the S3 Transfer Acceleration endpoint, which is a different service and not necessary for this scenario.

Since only one additional region we dont need global accelerators
