Automatic replication. Object Storage data is automatically replicated across three Fault Domains within an AD.

Answer

Manual replication

Answer

RAID 5

Answer

Not replicated

Question 2

You are using Storage Gateway to connect on-premises applications to OCI. How are file systems mapped?

Accepted Answer

Maps to Object Storage buckets. Storage Gateway maps local file systems to OCI Object Storage buckets.

Answer

Maps to Block Volumes

Answer

Maps to File Storage targets

Answer

Maps to Archive Storage only

Question 3

Which OCI storage service is best suited for big data workloads requiring high throughput?

Accepted Answer

Block Volume. Block Volume is optimized for high-performance throughput for data-intensive apps.

Answer

Archive Storage

Answer

Object Storage

Answer

File Storage

Question 4

You want to move data from a local server to OCI Object Storage. Which tool is recommended for large-scale data migration over the internet?

Accepted Answer

OCI CLI. OCI CLI with parallel multi-part upload is recommended for large data transfer.

Answer

OCI Data Transfer Appliance

Answer

Web Console

Answer

Storage Gateway

Question 5

Which THREE features are supported by OCI Object Storage buckets?

Accepted Answer

Object versioning to retain multiple variants of an object in the same bucket.. OCI Object Storage supports customer-managed encryption keys via Vault, cross-region replication, and versioning to protect against accidental overwrites or deletions.

Answer

Direct attachment to a Linux compute instance as a block storage device formatted with ext4.

Answer

POSIX-compliant file locking for multi-client NFS v3/v4 mounts directly from the bucket.

Question 6

An administrator needs to back up a critical Oracle Database running on an OCI Block Volume. The database spans across three separate block volumes that must be backed up simultaneously to ensure crash consistency. What is the most efficient feature to use?

Accepted Answer

OCI Volume Groups. Volume Groups allow you to group multiple block volumes together and perform coordinated operations like backups, clones, and cross-region replications simultaneously.

Answer

Object Storage Multipart Upload

Answer

Individual Block Volume Backups triggered sequentially

Answer

FSS Snapshots

Question 7

Which TWO methods can be used to transfer data from an on-premises data center into OCI Object Storage? (Choose two.)

Accepted Answer

OCI Data Transfer Appliance for offline data migration. On-premises data can be uploaded to Object Storage via the OCI CLI/API over the public internet or private VCN connections (FastConnect), or shipped physically using Data Transfer Appliances.

Answer

Directly mounting an Object Storage bucket as a local Windows NTFS drive via SMB protocol

Answer

Attaching an Object Storage bucket as an LVM logical volume to an on-premises server

Answer

Using Block Volume Export to push data into Object Storage buckets automatically

Question 8

An enterprise application requires long-term compliance retention for regulatory records stored in OCI Object Storage. The administrator must ensure that stored objects cannot be modified, overwritten, or deleted by any user, including administrators, for a mandated retention period. Which feature should be used?

Accepted Answer

Object Storage Object Lock (Retention Rules). Object Storage Object Versioining combined with Object Storage Object Lifecycle Rules or Object Lock (Retention Rules) prevents accidental or malicious deletion or modification of data for regulatory compliance.

Answer

Block Volume Replication

Answer

IAM Policy with Deny DELETE statements

Answer

Object Storage Bucket Access Policy with Read-Only permissions

Question 9

Which THREE statements are true regarding OCI Object Storage architecture and data durability? (Choose three.)

Accepted Answer

Checksums are automatically calculated and verified for data integrity.. OCI Object Storage is designed for high durability, stores data redundantly across availability domains or fault domains, and supports strong consistency for all operations.

Answer

Object Storage provides eventual consistency for bucket listing operations.

Answer

Objects larger than 50 GiB must be stored using Block Volume instead.

Question 10

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?

Accepted Answer

Directly select the existing backup in the console and choose to restore it to a volume in the target Availability Domain.. 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.

Answer

Copy the backup to the target region first, then restore it.

Answer

Export the backup to an Object Storage bucket, download it on-premises, and re-upload it to the new AD.

Answer

Create a volume clone in the source AD and attach it across ADs.

Question 11

You need to perform a backup of a production Block Volume. What is the recommended strategy to ensure data consistency?

Accepted Answer

Block Volume Backup. Creating a volume group backup or a block volume backup ensures point-in-time consistency.

Answer

RAID 0 striping

Answer

Object Storage replication

Answer

Manual file copy via SSH

Question 12

Which OCI service provides a POSIX-compliant file system?

Accepted Answer

File Storage Service. File Storage Service provides a standard NFS-based, POSIX-compliant file system.

Answer

Archive Storage

Answer

Object Storage

Answer

Block Volume

Question 13

Which THREE components are involved in OCI File Storage Service?

Accepted Answer

Export. File systems, mount targets, and exports are the main components.

Answer

Bucket

Answer

Backup gateway

Question 14

Which TWO characteristics apply to the OCI File Storage Service (FSS)?

Accepted Answer

Data in FSS is encrypted at rest by default.. FSS encrypts data at rest by default using KMS, and automatically provisions storage capacity as your file system grows without requiring upfront provisioning.

Answer

FSS is designed exclusively for single-instance high-performance computing (HPC) boot volumes.

Answer

FSS file systems can be natively mounted across multiple OCI regions simultaneously over the public internet.

Answer

Snapshots created in FSS consume additional baseline storage that must be explicitly pre-allocated.

Question 15

When using File Storage Service, how do you restrict access to the file system to specific instances?

Accepted Answer

Export Options. Export Options in FSS allow you to define access rules by IP or CIDR.

Answer

OS-level permissions only

Answer

IAM Policies only

Answer

Bucket Policies
