Answer: Enable S3 Transfer Acceleration on the S3 bucket in eu-north-1 and modify the application to utilize the accelerated S3 endpoint for data uploads.
The correct answer is B. Enabling S3 Transfer Acceleration on the S3 bucket in eu-north-1 and modifying the application to use the accelerated endpoint will reduce the latency by using the globally distributed edge locations in AWS, which speeds up the data transfer from remote regions to the centralized S3 bucket. This method takes advantage of the optimized network paths provided by AWS, resulting in significantly reduced lag time. Options A and D do not address the cross-regional data transfer lag. Option C adds complexity with cross-region replication and does not guarantee better performance compared to S3 Transfer Acceleration.

A company operates a highly available data collection application on Amazon EC2 in the eu-north-1 Region, which collects data from end-user devices and writes records to an Amazon Kinesis data stream. These records are processed by a set of AWS Lambda functions, and the processed output is stored in an Amazon S3 bucket located in eu-north-1. This S3 bucket serves as a data source for Amazon Athena. To expand its global presence, the company plans to deploy the data collection application, Kinesis data stream, and Lambda functions in the sa-east-1 and ap-northeast-1 Regions. However, the S3 bucket will remain in eu-north-1 to centralize data analysis. During initial testing of this new setup, significant data arrival lag from the new Regions to the S3 bucket in eu-north-1 was observed. What is the most effective solution to reduce this lag time?
A
Configure the Lambda functions in each of the two new Regions to operate within a VPC and establish an S3 gateway endpoint within that VPC.
B
Enable S3 Transfer Acceleration on the S3 bucket in eu-north-1 and modify the application to utilize the accelerated S3 endpoint for data uploads.
C
Establish an S3 bucket in each of the two new Regions, configure the application in each region to upload data to its respective S3 bucket, and set up S3 Cross-Region Replication to transfer data to the S3 bucket in eu-north-1.
D
Enhance the memory allocation for the Lambda functions to ensure they have multiple cores available and implement the multipart upload feature for data uploads to Amazon S3 from Lambda.
