A is the correct answer https://docs.aws.amazon.com/AmazonS3/latest/userguide/RequesterPaysBuckets.html

A. Configure the Requester Pays feature on the company's S3 bucket. Explanation: A. Configuring the Requester Pays feature on the company's S3 bucket is the most appropriate solution. With Requester Pays, the marketing firm's AWS account will be responsible for the data transfer costs when accessing the data in the S3 bucket, minimizing the data transfer costs for the consumer survey company. B. Configuring S3 Cross-Region Replication (CRR) from the company's S3 bucket to one of the marketing firm's S3 buckets would not be the most cost-effective solution, as the company would still be responsible for the data transfer costs.

Letter A

The Requester Pays feature allows the bucket owner to offload the data transfer costs to the requester. When this feature is enabled, the marketing firm would pay for the data transfer when they access the data in the survey company's S3 bucket, which effectively minimizes costs for the survey company. This means that the most cost-effective solution for the survey company, given that the marketing firm is accessing the data, is "A"

Sorry that was for the next question.

Read again - "The company wants to minimize the data transfer costs when the marketing firm requests data from the S3 bucket." So as long as the company saves money, bravo. We don't care about the marketing firm. When enabling Requester Pays, the marketing firm (requester) pays for the costs of data requests and data transfer out of the S3 bucket, instead of the data owner (the consumer survey company). B - CRR does not inherently reduce costs. In fact, replication incurs additional storage and transfer costs for the data owner, who would still bear the cost of replication, which contradicts the requirement to minimize their own data transfer costs. C - RAM is used to share resources like S3 buckets, but it doesn't affect data transfer costs. D - This helps reduce storage costs by moving objects between storage classes based on access patterns, but it doesn't reduce data transfer costs for requests made by the marketing firm.

transfering cost is not an effective solution for me

question ask for method to reduce cost in survey company, so A will do it

This is the same question as question 88. One difference is "it's data transfer costs" in question 88. Here it is "minimize the data transfer costs". A or B can be correct based on whether they are asking for reducing data transfer costs for survey company or both of them.

Ok Guys... The solution is A i understand, but if another company has to pay for the money i am saving that is not a solution for me... For me B is the Answer, is the most cost effective solution...

Answer B seems to be more logic, the question didn't mention which account will pay

Only 2 questions in this whole dump with "Configure the Requester Pays feature on the company’s S3 bucket." as an option, both times this is the correct answer.

The correct answer is B. Configure S3 Cross-Region Replication (CRR) from the company’s S3 bucket to one of the marketing firm’s S3 buckets. Explanation: Option A: Incorrect. The Requester Pays feature can help distribute the cost of data requests by billing the requestor, but it does not reduce the overall data transfer costs. It only shifts who pays for the data transfer, not the amount. Option B: Correct. S3 Cross-Region Replication (CRR) replicates the data to a bucket in the marketing firm's region. This allows the marketing firm to access the data from a local region, minimizing cross-region data transfer charges each time data is accessed.
