Question 25 of 100 | ← Chapter 14

Q1025. A consumer survey company has gathered data for several years from a specific geographic region. The company stores this data in an Amazon S3 bucket in an AWS Region.The company has started to share this data with a marketing firm in a new geographic region. The company has granted the firm's AWS account access to the S3 bucket. The company wants to minimize the data transfer costs when the marketing firm requests data from the S3 bucket.Which solution will meet these requirements?

Correct Answer: B. Configure S3 Cross-Region Replication (CRR) from the company's S3 bucket to one of the marketing firm's S3 buckets.

Explanation

To minimize data transfer costs when the marketing firm requests data from the S3 bucket, the best solution is:B. Configure S3 Cross-Region Replication (CRR) from the company's S3 bucket to one of the marketing firm's S3 buckets.Explanation:\1. S3 Cross-Region Replication (CRR): - By setting up CRR, the data from the company's S3 bucket will be automatically replicated to an S3 bucket in the marketing firm's AWS account and geographic region. This means that when the marketing firm accesses the data, they will do so from their own bucket in their region, significantly reducing data transfer costs associated with cross-region access.\2. Cost Efficiency: - Transferring data within the same AWS region is generally cheaper than transferring it across regions. This replication allows the marketing firm to access the data locally without incurring high cross-region transfer charges.Evaluation of Other Options:A. Configure the Requester Pays feature on the company's S3 bucket: - While Requester Pays allows the requester to bear the data transfer costs, it does not reduce the costs associated with cross-region data transfer itself. The marketing firm would still incur charges for data retrieved across regions.C. Configure AWS Resource Access Manager to share the S3 bucket with the marketing firm AWS account: - Sharing the bucket does not address the data transfer costs. The marketing firm would still incur costs when accessing the data across regions.D. Configure the company's S3 bucket to use S3 Intelligent-Tiering and sync to one of the marketing firm's S3 buckets: - While S3 Intelligent-Tiering optimizes storage costs, it does not directly impact data transfer costs. Syncing to the marketing firm's bucket would incur data transfer charges, especially if done cross-region.Conclusion:Option B is the most effective solution for minimizing data transfer costs when the marketing firm accesses data, as it allows for local access to replicated data in their region.
