Oracle Cloud Infrastructure (OCI) Object Storage is a scalable, highly durable service that allows you to store any type of data in a secure and cost-effective manner. The correct and incorrect statements regarding OCI Object Storage are as follows:
* A. Immutable Option: You can indeed set an immutable option for data in Object Storage using retention rules. This feature ensures that once data is written, it cannot be modified or deleted until the retention period expires, making it ideal for regulatory compliance.
* C. Object Lifecycle Rules: Object lifecycle policies allow you to automate the archiving or deletion of objects based on their age or other criteria, helping manage storage costs and data retention efficiently.
* D. Object Versioning: Versioning is enabled at the bucket level, not the namespace level. However, once enabled for a bucket, it helps retain, retrieve, and restore every version of every object stored in that bucket.
* B. Object Storage Sharing Across Tenancies: This statement isnot true. OCI Object Storage buckets and objects are specific to a tenancy and cannot be shared across different tenancies directly. Access to Object Storage resources is controlled within a single tenancy through IAM policies.
* Relevant OCI Documentation:
