1Z0-1072-26 Storage Practice Test 4 — 15 Questions

Question 1

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

Accepted Answer

It has a minimum storage duration commitment of 90 days.. 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.

Answer

Objects in Archive Storage can be read directly via GET requests without prior restoration.

Answer

It supports instant sub-second retrieval times for disaster recovery testing.

Question 2

Which TWO statements are true regarding OCI Storage Gateway? (Choose two.)

Accepted Answer

It runs as a virtual machine on-premises, such as on Oracle VM or VMware.. Storage Gateway is a cloud storage gateway that runs on-premises, translating file storage protocols (NFS) to object storage REST APIs.

Answer

It provides native block-level SAN connectivity over Fibre Channel.

Answer

It can only be used with Archive Storage for instant data retrieval.

Answer

It replaces the need for Object Storage buckets in the cloud entirely.

Question 3

Which THREE configuration options are available when creating a new OCI Object Storage bucket? (Choose three.)

Accepted Answer

Object Versioning (Enabled or Disabled). Option B is correct because Object Versioning is a bucket-level setting chosen at creation time, allowing you to enable or disable the retention of multiple versions of objects to protect against accidental overwrites or deletions. Option C is correct because when creating a bucket you select the encryption type: Oracle-managed keys (the default) or customer-managed keys stored in OCI Vault (KMS), which determines how objects in the bucket are encrypted at rest. Option D is correct because the bucket's default storage tier can be set to Standard or Infrequent Access, and this tier applies to objects uploaded to the bucket unless overridden per object. Option A is not a bucket creation setting, since IOPS/throughput limits are not provisioned for Object Storage buckets (that concept applies to block volume performance). Option E is not a creation option because cross-region replication is configured separately as a replication policy after the bucket exists, not as a parameter in the create-bucket workflow.

Answer

Maximum IOPS provisioning limit

Answer

Automatic cross-region replication destination region

Question 4

An OCI administrator needs to ensure that infrequently accessed data stored in an Object Storage bucket automatically transitions to Archive Storage after 90 days to reduce costs. Which feature should the administrator configure?

Accepted Answer

Object Storage Lifecycle Policy. Object Storage Lifecycle Policy rules can be created to automatically transition objects from Standard storage to Infrequent Access or Archive Storage based on a specified number of days since creation or modification.

Answer

Object Storage Replication Policy

Answer

OCI Data Transfer Service

Answer

Block Volume Backup Policy

Question 5

A database administrator requires a Block Volume attached to an Oracle Linux compute instance to deliver ultra-high IOPS and throughput with minimal latency for a high-transaction workload. Which volume performance level should be selected?

Accepted Answer

Ultra High Performance. OCI Block Volume performance levels range from Lower Cost to Ultra High Performance. Ultra High Performance is designed for the most demanding workloads, delivering up to 225,000 IOPS and 4,800 MB/s throughput per volume with sub-millisecond latency, making it the correct choice for a high-transaction database requiring ultra-high IOPS and minimal latency.

Answer

Archive

Answer

Lower Cost

Answer

Balanced

Question 6

An application running on an OCI compute instance needs to share a POSIX-compliant file system concurrently across multiple compute instances residing in different subnets of the same VCN. Which storage service is best suited for this requirement?

Accepted Answer

File Storage Service. File Storage Service (FSS) provides a durable, scalable, enterprise-grade network file system that can be accessed concurrently by thousands of compute instances using the standard NFS v3.0 protocol across availability domains and subnets within a VCN.

Answer

Block Volume

Answer

Object Storage

Answer

Local NVMe

Question 7

Which TWO statements are correct regarding OCI Block Volume backups and clones?

Accepted Answer

Block volume backups can be restored as new volumes in any Availability Domain within the same region.. Option C is correct because OCI Block Volume backups are regional constructs: a backup taken from a volume in one Availability Domain can be restored as a new block volume in any Availability Domain within the same region (though not across regions unless copied). Option D is correct because block volume clones leverage the Block Volume service's instant, space-efficient copy-on-write capability, so a clone can be created immediately from a source volume without requiring a completed backup first. Option A is incorrect because backups are stored in Object Storage (OCI Object Storage buckets), not in File Storage Service file systems. Option B is incorrect because restoring a backup creates a new volume and does not require deleting the parent/source volume. Option E is incorrect because a block volume clone is an AD-local copy and must reside in the same Availability Domain as the source volume, so it cannot be attached to instances in a different AD.

Answer

Block volume backups are stored directly in File Storage Service file systems.

Answer

Block volume backups require manual deletion of the parent volume before the backup can be restored.

Answer

A block volume clone can be attached to compute instances in a different Availability Domain than the source volume.

Question 8

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 9

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 10

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

Accepted Answer

Data in FSS is encrypted at rest by default.. Option B is correct because OCI File Storage Service encrypts all file system data at rest by default using Oracle-managed keys, with the option to use customer-managed keys in Vault, so no extra configuration is needed to get encryption. Option E is correct because FSS file systems are elastic: they automatically expand and shrink as data is written or deleted, and you are billed only for the storage actually used rather than a pre-provisioned capacity. Option A is wrong because FSS is a shared, network-attached NFS file system, not a block storage service for single-instance HPC boot volumes (that role belongs to Block Volume). Option C is wrong because an FSS file system is mounted within its own region and availability domain via a mount target; it is not natively mounted across multiple regions simultaneously over the public internet. Option D is wrong because FSS snapshots are space-efficient and consume storage only for changed data, and they do not require pre-allocated baseline capacity.

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 11

You need to store infrequently accessed data in Oracle Cloud Infrastructure (OCI) with the lowest possible cost while maintaining data retrieval times within a few hours. Which storage tier should you choose?

Accepted Answer

Archive Storage. Archive Storage is designed for long-term data retention at the lowest cost, with a retrieval time of up to 4 hours.

Answer

Block Volume

Answer

Standard Object Storage

Answer

Infrequent Access Object Storage

Question 12

A database application requires high-performance block storage with low latency. Which Block Volume performance tier should you select?

Accepted Answer

Ultra High Performance. The Ultra High Performance tier is designed for extreme IOPS requirements for databases.

Answer

Balanced

Answer

Higher Performance

Answer

Lower Cost

Question 13

You need to share a file system between multiple OCI Compute instances across different availability domains. Which service should you use?

Accepted Answer

File Storage Service. File Storage Service (FSS) is a shared file system that can be mounted across ADs in a region.

Answer
