Your company is planning to use the Simple Storage Service to host objects that users will access. You need to store the photos based on the date and you also need the folder structure to be concise. There is a speculation that there would be roughly 6000 GET requests per second. Which of the following is the right way to use object keys for optimal performance?

Answer options:

A.exampleawsbucket/photo1/2019-14-03-15-00-00/photo1.jpg
B.exampleawsbucket/sample/2019-14-03-15-00-00photo1.jpg
C.exampleawsbucket/2019-14-03-15-00-00/photo1.jpg
D.exampleawsbucket/sample/photo1.jpg

Answer – C
According to the latest AWS documentation, randomizing prefix naming is not required to improve S3 performance.
"For example, previously Amazon S3 performance guidelines recommended randomizing prefix naming with hashed characters to optimize performance for frequent data retrievals. You no longer have to randomize prefix naming for performance and can use sequential date-based naming for your prefixes."
Option A is incorrect because there is no need to use a subfolder of photo1.
Option B is incorrect because there is no need to use a subfolder of sample. It needs subfolders based on the date.
Option D is incorrect because it does not store the photos based on the date.
