MCQhard

An administrator is managing an OCI File Storage Service file system and notices that storage consumption has grown significantly. They want to identify which directories and users are consuming the most space. How can this be accomplished?

A.View the Storage Consumption metric in OCI Monitoring service aggregated by directory path.
B.Check the Object Storage Metrics explorer for FSS bucket utilization.
C.Mount the file system on a compute instance and use standard Linux tools such as 'du' or quota management.
D.Enable FSS Analytics in the OCI Console under Storage Administration.
AnswerC

FSS exposes standard POSIX/NFS interfaces, allowing standard Linux utilities to inspect directory and file-level consumption when mounted.

Why this answer

OCI File Storage Service does not provide a native per-directory usage reporting dashboard within the console, but administrators can mount the file system and use standard Linux utilities (like du or quota tools if configured via NFS) to analyze storage consumption.

An administrator needs to restore an encrypted block volume backup to a different Availability Domain within the same OCI region. How should this be achieved?

A.Copy the backup to the target region first, then restore it.
B.Export the backup to an Object Storage bucket, download it on-premises, and re-upload it to the new AD.
C.Create a volume clone in the source AD and attach it across ADs.
D.Directly select the existing backup in the console and choose to restore it to a volume in the target Availability Domain.
AnswerD

Block volume backups are regional resources and can be restored to any Availability Domain within the same region.

Why this answer

Block volume backups in OCI are stored in Object Storage and are automatically available across all Availability Domains within the same region. The administrator can directly restore the backup to a volume in any AD within that region.

Which THREE features are supported by OCI Object Storage buckets?

Select 3 answers
A.Direct attachment to a Linux compute instance as a block storage device formatted with ext4.
B.POSIX-compliant file locking for multi-client NFS v3/v4 mounts directly from the bucket.
C.Object versioning to retain multiple variants of an object in the same bucket.
D.Cross-region replication to automatically copy objects to a bucket in another OCI region.
E.Encryption of data at rest using Customer-Managed Keys (CMK) via OCI Vault.
AnswersC, D, E

Versioning protects data by maintaining previous versions when objects are overwritten or deleted.

Why this answer

OCI Object Storage supports customer-managed encryption keys via Vault, cross-region replication, and versioning to protect against accidental overwrites or deletions.

An administrator is planning an Object Storage data archiving strategy. Which THREE characteristics apply to OCI Archive Storage? (Choose three.)

Select 3 answers
A.It has a minimum storage duration commitment of 90 days.
B.Objects in Archive Storage can be read directly via GET requests without prior restoration.
C.It provides the lowest cost per gigabyte for storage in OCI.
D.Data retrieval requires a restoration request that can take up to 4 hours.
E.It supports instant sub-second retrieval times for disaster recovery testing.
AnswersA, C, D

Archive Storage enforces a minimum storage duration of 90 days.

Why this answer

Archive Storage is designed for long-term retention, offers the lowest storage cost, and requires data to be restored to the Infrequent Access or Standard tier before reading, with a restoration latency of up to 4 hours.

You need to configure an Object Storage lifecycle policy to automatically transition objects from the Standard tier to the Infrequent Access tier after 30 days, and then delete them after 365 days from creation. How should the rule be defined?

A.Configure an event rule in OCI Events Service to trigger a function that modifies the storage tier after 30 days.
B.Set the bucket storage policy to automatically purge objects after 365 days and use Object Versioning to handle the 30-day tier shift.
C.Create a single rule with transition after 30 days to Infrequent Access and deletion after 365 days.
D.Create two separate rules: one for transition at 30 days and another rule evaluated independently for deletion at 335 days.
AnswerC

OCI Object Storage lifecycle rules support combining multiple actions like transition and deletion in a single rule using age-based offsets.

Why this answer

Lifecycle rules use offset values based on object creation time. Transition and deletion rules can be chained by specifying days relative to the object's age.
