An application hosted in AWS allows users to upload videos to an S3 bucket. A user is required to be given access to upload some videos for a week based on the profile. How could this be accomplished in the best way possible?

Answer options:

A.Create an IAM bucket policy to provide access for one week.
B.Create a pre-signed URL for each profile which will last for one week.
C.Create an S3 bucket policy to provide access for one week.
D.Create an IAM role to provide access for one week.

Correct Answer – B
Pre-signed URLs are the perfect solution when you want to give temporary access to users for S3 buckets. So, whenever a new profile is created, you can create a pre-signed URL to ensure that the URL lasts for a week and allows users to upload the required objects.
For more information on pre-signed URLs, please visit the following URL:

For Choice D, the maximum time you can set for IAM Role Session is 12 hours. So this doesn`t satisfy the 1-week requirement.
