S3 Feature for Buckets

Answer - B.

The AWS documentation mention.

In general, bucket owners pay for all Amazon S3 storage and data transfer costs associated with their bucket.

A bucket owner, however, can configure a bucket to be a Requester Pays bucket.

With Requester Pays buckets, the requester instead of the bucket owner pays the cost of the request and the data download from the bucket.

The bucket owner always pays the cost of storing data.

The correct answer is B. Requester Pays.

Amazon S3 (Simple Storage Service) is an object storage service provided by Amazon Web Services (AWS). It is used to store and retrieve any amount of data from anywhere on the web. When data is stored in an S3 bucket, the bucket owner is responsible for paying the cost of storage, but not for the cost of data transfer. Data transfer costs are usually incurred by users who download or retrieve data from an S3 bucket.

The Requester Pays feature allows S3 bucket owners to designate that the requester, rather than the bucket owner, will be responsible for the data transfer costs. This means that if a user downloads data from a bucket that has Requester Pays enabled, the user will be responsible for the cost of the download, not the bucket owner. This can be useful in situations where bucket owners want to allow public access to their data but do not want to be responsible for the cost of data transfer.

In contrast, Transfer Acceleration is a feature that allows faster transfers of data over the internet to and from an S3 bucket using Amazon's content delivery network (CDN). This feature does not affect who is responsible for paying data transfer costs.

Billing request and Reduced S3 costs are not actual features of S3. Billing requests are made by customers to AWS to obtain detailed billing information, while Reduced S3 costs could be referring to using certain S3 storage classes or cost-saving measures such as lifecycle policies to reduce the overall cost of storing data in S3. However, neither of these options directly relate to transferring costs from the bucket owner to the requester.
