You work for a health insurance company that stores many patients' health records in an OCI Object Storage bucket named “HealthRecords”.

  Each record needs to be securely stored for a period of 5 years for regulatory compliance purposes and cannot be modified, overwritten, or   deleted during this time period.

  What can you do to meet this requirement?

• Enable encryption on the HealthRecords bucket using your own vault master encryption keys.

• Create an OCI Object Storage Time-bound Retention Rule on the HealthRecords bucket for five years. Enable Retention Rule Lock on this bucket.

• Create an OCI Object Storage Lifecycle Policies rule to archive objects in the HealthRecords bucket for five years.

• Enable versioning on the HealthRecords bucket.

Answer explanation

For Object Storage regulatory compliance, you create a time-bound retention rule and specify a duration. Object modification and deletion are prevented for the duration specified. Duration is applied to each object individually, and is based on the object's Last Modified timestamp. Lock the rule as required.
