1Z0-1072-26 Storage Practice Test 6 — 15 Questions

Question 1

What happens if you delete a versioned object in Object Storage?

Accepted Answer

A delete marker is created. A delete marker is placed on the object, preserving the version.

Answer

An error is returned

Answer

The object is moved to Archive

Answer

The object is permanently deleted

Question 2

Which storage type offers the highest performance for random I/O operations?

Accepted Answer

Block Volume. Block Volume with Ultra High Performance is built for random I/O.

Answer

Archive Storage

Answer

File Storage

Answer

Object Storage

Question 3

How do you ensure data integrity for uploads to Object Storage?

Accepted Answer

MD5 checksum. MD5 checksums are used to verify data integrity during uploads to Object Storage by comparing the checksum of the uploaded object with the local file. If the checksums match, the data was transferred without corruption. OCI Object Storage supports MD5 checksums for upload validation, making it the correct mechanism for ensuring integrity.

Answer

Encryption

Answer

Versioning

Answer

HTTPS

Question 4

You are setting up a File Storage mount target. What is required at the subnet level?

Accepted Answer

An IP address within the subnet. An OCI File Storage mount target is a virtual network interface (NIC) that resides in a specific subnet within a VCN, and it must be assigned an available private IP address from that subnet's CIDR block. The mount target is what NFS clients connect to over TCP/2049, so it needs a routable private IP within the VCN. Without a free IP in the subnet, the mount target cannot be created.

Answer

A NAT Gateway

Answer

A Public IP

Answer

A Service Gateway

Question 5

What is the main benefit of using a 'Clone' of a block volume?

Accepted Answer

Creating an immediate, independent volume. A block volume clone creates an immediate, point-in-time copy of the volume that is fully independent of the source — you can attach it to another instance, modify it, or delete it without affecting the original. This is the defining benefit: instant, independent duplication for use cases like test/dev refreshes, data sharing, or pre-upgrade snapshots. It is not a backup mechanism, does not deduplicate or compress to save space, and is region-scoped, so it cannot serve as a cross-region migration tool.

Answer

Backup automation

Answer

Reducing storage usage

Answer

Moving to another region

Question 6

Which service is the best choice for storing thousands of small, frequently accessed image files?

Accepted Answer

Object Storage. Object Storage is optimized for high-scale, flat-namespace object storage.

Answer

Archive Storage

Answer

Block Volume

Answer

File Storage

Question 7

If you detach a Block Volume, what happens to the data?

Accepted Answer

Data remains intact. Detaching a Block Volume in Oracle Cloud Infrastructure (OCI) is a non-destructive operation. The data on the volume persists independently of its attachment state; the volume is simply disassociated from the instance. The data remains intact and can be reattached to the same or a different instance later. This is a fundamental characteristic of block storage, which provides persistent, durable storage separate from compute lifecycle.

Answer

Data is lost if not backed up

Answer

Data is encrypted for migration

Answer

Data is deleted

Question 8

Which tool provides a graphical way to manage Object Storage lifecycle policies?

Accepted Answer

Web Console. The OCI Web Console provides the interface for lifecycle policy management.

Answer

OCI CLI

Answer

API Explorer

Answer

Terraform

Question 9

When creating a volume backup, what is the 'Incremental' option?

Accepted Answer

Backs up only new data. Incremental backups only copy data that has changed since the last backup.

Answer

Deletes the old backup

Answer

Compresses the volume

Answer

Backs up the entire volume

Question 10

What is the main advantage of the OCI Block Volume performance tier selection?

Accepted Answer

Customizable IOPS and throughput. OCI Block Volume performance tiers (Lower Cost, Balanced, Higher Performance, and Ultra High Performance) let administrators choose and adjust IOPS and throughput independently of capacity. This flexibility to customize performance to workload needs is the main advantage, allowing cost optimization without over-provisioning.

Answer

Always fixed price

Answer

Mandatory for boot volumes

Answer

Only for production

Question 11

Which OCI service is most appropriate for storing static website content?

Accepted Answer

Object Storage. Object Storage is frequently used to host static website assets.

Answer

File Storage

Answer

Block Volume

Answer

Archive Storage

Question 12

Which THREE actions can you perform on a block volume?

Accepted Answer

Resize the volume. Backups, clones, and resizing are common operations for block volumes.

Answer

Mount as a website

Answer

Convert to object storage

Question 13

Which TWO of the following are valid Object Storage tiers in OCI?

Accepted Answer

Archive. Standard and Archive are the primary tiers in OCI Object Storage.

Answer

Fast Storage

Answer

Temporary Storage

Answer

Cold Storage

Question 14

Which THREE features are provided by File Storage Service?

Accepted Answer

NFSv3 support. Snapshots, NFS compatibility, and export options are key features of FSS.

Answer

Automatic tiering to Archive

Answer

Cross-region replication

Question 15

You are using File Storage and want to mount it to an instance. What is the necessary network step?

Accepted Answer

Open NFS ports in security list. You must allow ingress for NFS and Network Status Monitor traffic on the subnet's security list.

Answer

Enable DHCP

Answer

Open port 80

Answer

Install iSCSI initiator
