Which statement is true regarding the creation of pre-authenticated requests in OCI Object Storage?

The statement about changing the bucket visibility not affecting existing pre-authenticated requests is accurate. In Oracle Cloud Infrastructure (OCI) Object Storage, when you create a pre-authenticated request, it is associated with a specific object or bucket and allows users to perform defined actions without requiring authentication credentials. If the visibility of the bucket is changed after the pre-authenticated request has been created, it will not invalidate or alter those requests. This means that existing pre-authenticated requests remain functional and can still be used to access the objects or contents as originally intended, even if the visibility settings of the bucket are modified later on.

This characteristic is important because it allows for greater flexibility in managing access to resources while ensuring that any pre-existing permissions under pre-authenticated requests are maintained despite changes to bucket settings. This facilitates smoother operations and access rights for resources that have already been configured with pre-authenticated requests.
