Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Direct attachment to a Linux compute instance as a block storage device formatted with ext4.
Why it's wrong here
Object storage is object-based and accessed via REST APIs or storage gateway, not attached as a block device.
- ✗
POSIX-compliant file locking for multi-client NFS v3/v4 mounts directly from the bucket.
Why it's wrong here
Object Storage does not support NFS mounting; File Storage Service provides POSIX-compliant NFS mounts.
- ✓
Object versioning to retain multiple variants of an object in the same bucket.
Why this is correct
Versioning protects data by maintaining previous versions when objects are overwritten or deleted.
- ✓
Cross-region replication to automatically copy objects to a bucket in another OCI region.
Why this is correct
Object Storage replication allows asynchronous copying of objects across regions.
- ✓
Encryption of data at rest using Customer-Managed Keys (CMK) via OCI Vault.
Why this is correct
Buckets can be encrypted using keys managed by customers in OCI Vault.
