Q239.A company has a mobile app with users in Europe. When the app is used it downloads a configuration file that is device and app version-specific. The company has the following architecture:--Configuration files are stored in Amazon S3 in the eu-west-1 Region and served to the users using Amazon CloudFront.-- Lambda@Edge is used to extract the device and version information from the app requests. It then updates the requests to load the correct configuration.The company uses the configuration file load time as a key performance metric and targets a response time of 100 ms or less. The app recently launched in the ap-southeast-2 Region and the latency for requests from users in Australia is significantly above the 100 ms target. A solutions
Architect needs to recommend a solution.Which solution will reduce latency for users in Australia?
A.Create an S3 bucket in the ap-southeast-2 Region. Use cross-Region replication to synchronize from the bucket in the eu-west-1 Region. Modify Lambda@Edge to access Amazon S3 in the Region that is closest to the user. B.Configure S3 Transfer Acceleration on the bucket.Modify Lambda@Edge to access Amazon S3 using the Transfer Acceleration endpoint in the Region that is closest to the user. C.Configure S3 Transfer Acceleration on the bucket. Add the Transfer Acceleration Edge endpoints for Australia and Europe as CloudFront origins. Modify Lambda@Edge to update the origin of the request to be the Transfer Acceleration endpoint in the Region that is closest to the user. D.Create an S3 bucket in the ap-southeast-2 Region. Use cross-Region replication to synchronize from the bucket in the eu-west-1 Region.Create an Amazon Route 53 hosted zone with latency-based routing configured for both buckets. Modify Lambda@Edge to update the origin of the request to be the Route 53 hosted zone that is closest to the user.正确答案D
