A research center is migrating to the AWS Cloud and has moved its on-premises 1 PB object storage to an Amazon S3 bucket. One hundred scientists are using this object storage to store their work- related documents. Each scientist has a personal folder on the object store. All the scientists are members of a single IAM user group. The research center's compliance officer is worried that scientists will be able to access each other's work.

Which combination of actions should a solutions architect take to meet these requirements? (Select TWO)
