You have an S3 bucket hosted in AWS that is used to store the promotional videos you upload. You need to provide users access to the S3 bucket`s object for a limited duration of time. How could this be achieved?

Answer options:

A.Use versioning and enable a timestamp for each version.
B.Use Pre-signed URLs with session duration.
C.Use IAM Roles with a timestamp to limit the access.
D.Use IAM policies with a timestamp to limit the access.

Correct Answer - B
AWS Documentation mentions the following.
All objects by default are private. Only the object owner has permission to access these objects. However, the object owner can optionally share objects with others by creating a pre-signed URL, using their own security credentials, to grant time-limited permission to download the objects.
