1Z0-1072-26 Storage Practice Test 5 — 15 Questions

Question 1

Which encryption method is used by default for all Object Storage buckets?

Accepted Answer

AES-256 server-side encryption. OCI Object Storage automatically encrypts all data at rest using AES-256.

Answer

RSA-4096 client-side encryption

Answer

No encryption by default

Answer

TLS 1.3 only

Question 2

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

Question 3

You need to increase the size of an existing Block Volume. What is the correct procedure?

Accepted Answer

Use the 'Resize' action in the console. You can increase the size of a volume without detaching it, then expand the file system on the OS.

Answer

Snapshot and clone

Answer

Delete and recreate the volume

Answer

Attach a second volume and mirror

Question 4

You have a large dataset in Object Storage that needs to be accessed by an on-premises server. What is the most efficient way to access this data via a local file interface?

Accepted Answer

Use Storage Gateway. Storage Gateway provides a file-system interface to Object Storage.

Answer

Use Mount Targets

Answer

Use OCI CLI to download everything

Answer

Use FastConnect alone

Question 5

You are migrating a database that requires a consistent point-in-time snapshot of multiple volumes. What should you use?

Accepted Answer

Volume Groups. Volume Groups allow you to create a consistent point-in-time snapshot across multiple volumes simultaneously, which is essential for database consistency. Individual volume backups (B) are taken independently and may not be crash-consistent across volumes.

Answer

Individual volume backups

Answer

Storage Gateway

Answer

Object Storage replication

Answer

Clone the volumes

Question 6

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 7

What is the primary benefit of enabling 'Versioning' on an Object Storage bucket?

Accepted Answer

Recovery from accidental deletion. Versioning protects against accidental overwrites or deletions by keeping historical versions.

Answer

Faster data access

Answer

Lower storage costs

Answer

Improved data security

Question 8

How can you ensure that data in an Object Storage bucket remains unchanged for a specific period?

Accepted Answer

Retention Rules. Retention rules on a bucket prevent modifications or deletions for a defined duration.

Answer

Encryption

Answer

IAM policies

Answer

Lifecycle policies

Question 9

What is the primary way to access an Object Storage bucket via a private endpoint?

Accepted Answer

Service Gateway. A Service Gateway allows private access from a VCN to Object Storage.

Answer

Internet Gateway

Answer

NAT Gateway

Answer

DRG

Question 10

What is the primary purpose of OCI Object Storage?

Accepted Answer

Unstructured data storage. OCI Object Storage is a highly durable, scalable service designed for storing unstructured data such as images, videos, logs, backups, and documents. It uses a flat namespace with buckets and objects, accessed via REST APIs, and is not intended for block-level or database workloads. This makes 'unstructured data storage' the defining purpose.

Answer

High-performance cache

Answer

Database storage

Answer

OS swap space

Question 11

You want to use your own encryption keys for Object Storage. What feature should you use?

Accepted Answer

OCI Vault. OCI Vault allows you to manage keys for server-side encryption.

Answer

Public keys

Answer

IAM policies

Answer

Encryption Gateway

Question 12

Which type of storage is required for Boot Volumes?

Accepted Answer

Block Volume. Boot volumes are special block volumes used to boot compute instances.

Answer

File Storage

Answer

Object Storage

Answer

Ephemeral Storage

Question 13

What is the default replication method for Object Storage buckets?

Accepted Answer

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 14

Which service should you use to migrate physical data centers to OCI via physical hardware shipping?

Accepted Answer

Data Transfer Service. Data Transfer Service uses physical appliances to move data.

Answer

Storage Gateway

Answer

FastConnect

Answer

Object Storage replication

Question 15

Which file system protocol does OCI File Storage Service support?

Accepted Answer
