A media firm uses the Amazon S3 bucket to save all videos shared by reporters across the globe. Operation Team has instructed all reporters to use only Multipart Uploads while uploading these large-sized videos to Amazon S3 bucket in each region. Most of the reporters are working from remote areas & face challenges in uploading videos. The Finance Team is concerned about high costs incurred by saving data in the Amazon S3 bucket & seeking your guidance. Post verification, you observe a large number of incomplete uploads in Amazon S3 buckets in each region. The uncompleted uploads can be deleted after a certain period of time.
Which of the following actions can minimize charges for saving video files in the Amazon S3 bucket?

Answer options:

A.Reporter`s need to compress video files locally before uploading to Amazon S3 bucket.
B.Reporter’s need to upload Videos to Amazon S3 Glacier to save additional charges.
C.Create a Lifecycle Policy to move all incomplete Multipart uploads to Amazon S3 Glacier after weeks’ time from initiation.
D.Create a Lifecycle Policy to delete all incomplete Multipart uploads after weeks’ time from initiation.

Correct Answer: D
Incomplete Multipart Uploads incur storage charges on the Amazon S3 bucket. Lifecycle rules can be used to abort the uploading of multipart uploads that are incomplete since a specific time frame & also deletes these parts to free up storage, reducing costs for this storage.
Option A & B are incorrect as Incomplete Multipart Uploads incur charges. These charges can be stopped by stopping multipart uploads.
Option C is incorrect as Moving all incomplete Multipart uploads to Amazon S3 Glacier would not completely reduce the cost for storing data. As data in Amazon S3 Glacier would incur cost, it would be less than data storing the Amazon S3 bucket. Also, incomplete Multipart uploads would not be used until fully uploaded.
