Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 88 discussion

this question is too vague imho if the question is looking for a way to incur charges to the European company instead of the US company, then requester pay makes sense. if they are looking to reduce overall data transfer cost, then B makes sense because the data does not leave the AWS network, thus data transfer cost should be lower technically? A. makes sense because the US company saves money, but the European company is paying for the charges so there is no overall saving in cost when you look at the big picture I will go for B because they are not explicitly stating that they want the other company to pay for the charges

"Typically, you configure buckets to be Requester Pays buckets when you want to share data but not incur charges associated with others accessing the data. For example, you might use Requester Pays buckets when making available large datasets, such as zip code directories, reference data, geospatial information, or web crawling data." https://docs.aws.amazon.com/AmazonS3/latest/userguide/RequesterPaysBuckets.html

No idea but I guess B. request payer sounds like stpd

it's A because the company will not pay extra cost

Ans B... because we want an overall cost-effective solution; A simply offloads the cost to someone else...

replication cost money . in other for the sender company to cut cost the requester must pay the transfer cost .Leveraging the requester pay options is convenient on the part of the company that is sharing .

because in question we are said to reduce our charges not to completely put them on the other organization

Correct A. Configure the Requester Pays feature on the company's S3 bucket. This feature ensures that the party requesting the data pays for the data transfer costs instead of the bucket owner. Incorrect B. Configure S3 Cross-Region Replication from the company's S3 bucket to one of the marketing firm's S3 buckets. Cross-Region Replication incurs additional storage and transfer costs as data is replicated across regions. This would increase costs rather than reduce them.

Option B makes more sense because the data transferred remains within the AWS private network, in my opinion, option A is incorrect because it doesn't reduce the overall transfer charges, it just shifts them from the American company to the European company.

Definitely B

both are part of same company. Option A still incur changes for the company. Option B will help to save some cost sharing the data in both the regions.

Answer: A

100% answer is A. Question doesnt state anything about the other company saving costs, only the US company.

(A) IS INCORRECT: The European marketing firm works for the survey company. The survey company pays the marketing firm to sell its data in Europe. (A) would incur a cost on the marketing firm that would be passed onto the survey company. (B) is correct: CRR reduces cost.

In this setup, anyone who requests data from the S3 bucket must cover the cost of the data transfer and request charges. This approach is ideal for S3 bucket owners who share large datasets with other users or organizations and want to avoid bearing the cost of data transfer. This would be the most direct way to ensure that the survey company's data transfer costs remain minimal while sharing data with the European marketing firm. The marketing firm, as the requester, will pay for the data they access or transfer.

The most suitable solution for minimizing data transfer costs while sharing data with the European marketing firm is: B. Configure S3 Cross-Region Replication from the company's S3 bucket to one of the marketing firm's S3 buckets.

S3 Cross-Region Replication: This feature automatically replicates objects from the source bucket (owned by the survey company) to a destination bucket (owned by the marketing firm) in a different AWS region. By replicating the data to the marketing firm's region, data transfer costs can be minimized, as data transfers within the same AWS region are typically cheaper than those across regions. Cost Efficiency: Since the marketing firm is located in Europe, having the data replicated to an S3 bucket in a European AWS region reduces the data transfer costs associated with transferring data across regions.
