Which of the following statements is true regarding OCI object storage?

The chosen statement asserts that while you cannot append data to an object once it has been uploaded, you can replace it. This is accurate in the context of OCI Object Storage, where each object is immutable after it has been created. If you need to modify the contents of an object, you must upload a new version of that object, effectively replacing the previous one. This characteristic ensures data integrity and consistency within the storage architecture.

With OCI Object Storage, objects serve as distinct units of storage, and once they are uploaded, they cannot be altered directly. The operation of replacing an object allows for updates while maintaining the original object's original version until the new one successfully replaces it.

The concept surrounding immutability is a key feature of object storage systems, promoting reliability and version control. On the other hand, attempting to append data directly to an existing object contradicts this fundamental property of object storage.

When it comes to the other statements, the claim that objects can be edited in place directly contradicts the immutable nature of object storage. The ability to declare each bucket as private or public is also true, but it does not pertain directly to the nature of how objects are handled or modified.
