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

File Storage exposes a standard NFS mount, so mounting it on a compute instance and running Linux tools such as 'du' or quota reporting reveals per-directory and per-user consumption, since OCI provides no native usage breakdown.

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.

Which THREE storage options can be used with OCI Compute instances?

Select 3 answers
A.File Storage
B.Local SSD only
C.Block Volume
D.Tape drive
E.Object Storage
AnswersA, C, E

Oracle Cloud Infrastructure File Storage satisfies the requirement for a fully managed network-attached storage solution that can be mounted simultaneously across multiple OCI Compute instances using the industry-standard Network File System version 3 protocol. This capability addresses the compute storage constraint for shared, read-write file access over a virtual cloud network, enabling distributed applications and multi-instance workloads to securely share data concurrently within a designated availability domain without manual infrastructure provisioning.

Why this answer

Block Volume, File Storage, and Object Storage are standard.

MCQeasy

A media company stores millions of video files in an OCI Object Storage bucket. The files are accessed frequently for the first 30 days after upload, then rarely accessed but must remain immediately available for 90 days. After 90 days, the files are archived for compliance and can tolerate hours of retrieval latency. The storage administrator needs to minimize storage costs while meeting these access patterns. What should the administrator do?

A.Create a lifecycle policy that transitions objects directly from Standard to Archive after 30 days.
B.Use the OCI Storage Gateway to cache frequently accessed objects on-premises and tier the rest to Archive.
C.Create a lifecycle policy that transitions objects from Standard to Infrequent Access after 30 days, then to Archive after 90 days.
D.Enable object versioning on the bucket and manually move objects to Archive after 90 days.
AnswerC

This lifecycle policy matches the access pattern exactly: Standard for the first 30 days, Infrequent Access for the next 60 days, and Archive thereafter. OCI Object Storage lifecycle policies support multiple transition rules based on object age, and this sequence reduces cost by moving data to cheaper tiers as access frequency drops.

Why this answer

A lifecycle policy that transitions objects from Standard to Infrequent Access after 30 days and then to Archive after 90 days aligns with the access frequency and retrieval latency requirements. It automates cost reduction without manual intervention. The other options either skip the intermediate tier, fail to automate, or introduce irrelevant on-premises caching.

Exam trap

The trap here is assuming that Archive is suitable for data that must remain immediately available, or that versioning or Storage Gateway can automate tier transitions.

MCQhard

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

A.Storage Gateway
B.Data Transfer Service
C.FastConnect
D.Object Storage replication
AnswerB

Migrating entire physical data centres involves transferring massive volumes of enterprise data where network bandwidth is either too constrained or too slow to make online transmission viable. The Data Transfer Service satisfies this specific throughput constraint by allowing organisations to securely copy data onto physical storage appliances provided by Oracle, which are then physically shipped to an OCI data centre for ingestion. This hardware-shipping mechanism bypasses internet latency limitations entirely, making it the optimal choice for large-scale data migration projects.

Why this answer

Data Transfer Service uses physical appliances to move data.

MCQeasy

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?

A.Object Storage Replication Policy
B.Object Storage Lifecycle Policy
C.OCI Data Transfer Service
D.Block Volume Backup Policy
AnswerB

A lifecycle policy defines rules that automatically transition objects between storage tiers, such as moving infrequently accessed data to Archive Storage after 90 days. It satisfies the stem's requirement for automatic, cost-reducing tiering without manual intervention.

Why this answer

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.

Multi-Selecthard

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

Select 2 answers
A.FSS is designed exclusively for single-instance high-performance computing (HPC) boot volumes.
B.Data in FSS is encrypted at rest by default.
C.FSS file systems can be natively mounted across multiple OCI regions simultaneously over the public internet.
D.Snapshots created in FSS consume additional baseline storage that must be explicitly pre-allocated.
E.File systems automatically grow and shrink dynamically as files are added or deleted, without requiring manual capacity provisioning.
AnswersB, E

OCI File Storage Service encrypts all file systems at rest by default using AES-256, with keys managed by Oracle or customer-managed via the Vault service. This satisfies the stem's requirement for a genuine FSS characteristic, since encryption is applied automatically at creation without any manual configuration.

Why this answer

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.

MCQmedium

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?

A.Object Storage Multipart Upload
B.OCI Volume Groups
C.Individual Block Volume Backups triggered sequentially
D.FSS Snapshots
AnswerB

OCI Volume Groups directly satisfy the requirement to back up multiple block volumes simultaneously by allowing administrators to group multiple volumes and create crash-consistent point-in-time backups across all attached disks concurrently. This feature ensures data integrity for multi-volume databases without requiring manual scripting or downtime to coordinate individual volume snapshots.

Why this answer

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

Multi-Selectmedium

Which TWO of the following are valid ways to secure an Object Storage bucket?

Select 2 answers
A.Disk-level formatting
B.Kernel hardening
C.IAM policies
D.RAID configuration
E.Bucket policies
AnswersC, E

Identity and Access Management (IAM) policies utilise fine-grained statements containing subjects, resources, and verbs to enforce principle-of-least-privilege access control at the compartment or tenancy level. This satisfies the requirement to secure an Object Storage bucket by enabling administrators to programmatically define precisely which users or groups can read, write, or manage bucket contents without exposing underlying storage endpoints publicly.

Why this answer

Bucket policies and IAM policies are the primary ways to secure access.

MCQhard

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

A.Open NFS ports in security list
B.Enable DHCP
C.Open port 80
D.Install iSCSI initiator
AnswerA

Mounting an Oracle Cloud Infrastructure File Storage service to a compute instance requires network traffic to traverse Network File System protocols, which fundamentally rely on specific TCP and UDP ports. To satisfy the stem constraint of successfully establishing the mount operation, you must configure the associated security list to permit inbound and outbound traffic over TCP and UDP ports 2048, 2049, and 2050, alongside port 111 for the Remote Procedure Call binder. Without these explicit firewall rules, the instance cannot communicate with the mount target endpoints.

Why this answer

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

Which THREE of the following are benefits of using OCI Object Storage?

Select 3 answers
A.Supports SQL queries natively
B.High durability
C.Latency lower than NVMe
D.IAM integration
E.Scalability
AnswersB, D, E

OCI Object Storage provides exceptional durability by redundantly replicating all stored data across multiple fault domains within a region, and synchronously across availability domains in multi-AD regions. This architectural design satisfies the high durability requirement specified in the question stem. Data integrity is continuously monitored using checksums, and corrupted data is automatically detected and healed using redundant copies, ensuring that enterprise workloads maintain long-term information resilience without risk of silent data loss.

Why this answer

Durability, scalability, and integration with IAM are key benefits.

11
MCQmedium

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

A.Deletes the old backup
B.Compresses the volume
C.Backs up only new data
D.Backs up the entire volume
AnswerC

Incremental backups capture only blocks changed since the previous backup, rather than the full volume each time. This reduces storage consumption and backup duration while still allowing full restoration when combined with the base backup.

Why this answer

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

12
MCQmedium

Which type of storage is required for Boot Volumes?

A.File Storage
B.Object Storage
C.Ephemeral Storage
D.Block Volume
AnswerD

Block volumes provide the low-latency, persistent block-level access required for operating system kernels to initialise and execute boot sequences. Unlike object storage, which lacks the necessary file system structure for mounting root partitions, block storage allows the hypervisor to present the volume as a local disk. This satisfies the fundamental requirement for persistent, bootable storage by enabling the instance to maintain its state and configuration across reboots, ensuring the compute resource can successfully load its environment independently of Microsoft Entra ID authentication processes.

Why this answer

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

13
MCQhard

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

A.A NAT Gateway
B.A Public IP
C.A Service Gateway
D.An IP address within the subnet
AnswerD

Mounting a File Storage target necessitates a dedicated private IP address from the chosen subnet’s CIDR block to facilitate network communication. This requirement satisfies the subnet-level constraint by ensuring the mount target possesses a unique identity within the virtual cloud network to route NFS traffic effectively. Without this specific IP allocation, the storage service cannot establish a functional endpoint for client instances to mount the file system, as the network interface must be addressable within the local subnet's routing domain.

Why this answer

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.

Exam trap

1Z0-1072-26 often tests whether candidates confuse the networking prerequisites for different OCI services — mount targets need only a private IP in a subnet, but candidates incorrectly reach for NAT/Service Gateways because those are common in other OCI networking questions.

How to eliminate wrong answers

Option A is wrong because a NAT Gateway is only needed for outbound internet access from private subnets — it has nothing to do with creating a mount target, which is an internal VCN resource. Option B is wrong because a public IP is not required; mount targets use private IPs and are accessed over the VCN's internal network (or via FastConnect/VPN/peering), never directly from the internet. Option C is wrong because a Service Gateway is used to access OCI public services like Object Storage or the OCI API from a private subnet without traversing the internet — File Storage mount targets do not require a Service Gateway to function.

14
MCQmedium

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?

A.Block Volume
B.Object Storage
C.File Storage Service
D.Local NVMe
AnswerC

Oracle Cloud Infrastructure File Storage utilises the Network File System (NFS) protocol to provide a fully managed, POSIX-compliant file system. It satisfies the requirement for concurrent access across multiple compute instances by supporting simultaneous mounting from various subnets within a Virtual Cloud Network. This architecture enables multiple clients to read and write to the same shared data volume concurrently, ensuring the necessary interoperability for distributed applications that require a shared, consistent file-level storage interface across the entire network topology.

Why this answer

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.

15
MCQmedium

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

A.OS-level permissions only
B.IAM Policies only
C.Bucket Policies
D.Export Options
AnswerD

Export options enable granular control over file system access by defining specific IP addresses or CIDR blocks within the mount target configuration. By specifying the exact source network or individual instance addresses, you restrict access to authorised clients only. This mechanism satisfies the requirement to limit connectivity to specific instances, as the File Storage Service enforces these rules at the network layer, ensuring that only permitted compute resources can successfully mount and interact with the exported file system.

Why this answer

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

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

Select 2 answers
A.Block volume backups are stored directly in File Storage Service file systems.
B.Block volume backups require manual deletion of the parent volume before the backup can be restored.
C.Block volume backups can be restored as new volumes in any Availability Domain within the same region.
D.Block volume clones can be created instantly without waiting for a full backup to complete.
E.A block volume clone can be attached to compute instances in a different Availability Domain than the source volume.
AnswersC, D

Block volume backups are regional artefacts, so restoring them is not confined to the source Availability Domain. You can create the new volume in any AD within the same region, which satisfies the stem's requirement of cross-AD restoration.

Why this answer

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.

17
MCQmedium

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

A.Faster data access
B.Lower storage costs
C.Improved data security
D.Recovery from accidental deletion
AnswerD

Enabling versioning ensures that when an object is deleted, the system creates a delete marker rather than permanently removing the data. This mechanism allows administrators to restore previous object states by simply removing the marker, directly addressing the requirement for recovery from accidental deletion. By maintaining a comprehensive history of every modification and removal, the bucket provides a robust safeguard against human error, ensuring that data remains retrievable even after an overwrite or an unintended delete command has been executed.

Why this answer

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

18
Multi-Selectmedium

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

Select 2 answers
A.It provides native block-level SAN connectivity over Fibre Channel.
B.It runs as a virtual machine on-premises, such as on Oracle VM or VMware.
C.It can only be used with Archive Storage for instant data retrieval.
D.It replaces the need for Object Storage buckets in the cloud entirely.
E.It translates file operations (NFS) into Object Storage REST API calls.
AnswersB, E

OCI Storage Gateway functions as a software appliance deployed as a virtual machine within an on-premises environment. By supporting hypervisors like Oracle VM and VMware, it satisfies the deployment constraint requiring local infrastructure integration to bridge on-premises file systems with OCI Object Storage. This architecture allows administrators to manage data movement seamlessly without requiring a direct connection to Microsoft Entra ID, ensuring that existing virtualisation hosts can effectively cache and transfer data to the cloud while maintaining local access performance.

Why this answer

Storage Gateway is a cloud storage gateway that runs on-premises, translating file storage protocols (NFS) to object storage REST APIs.

19
MCQmedium

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

A.Encryption
B.Versioning
C.HTTPS
D.MD5 checksum
AnswerD

Object Storage automatically generates and verifies an MD5 hash when you upload a file. By calculating the checksum of the payload during transmission and comparing it against the value computed upon receipt, the service guarantees that data has not been corrupted or altered in transit. This direct verification mechanism satisfies the requirement to ensure data integrity during uploads, as any mismatch in the checksum triggers an error, preventing the storage of incomplete or corrupted files.

Why this answer

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.

Exam trap

1Z0-1072-26 often tests the confusion between confidentiality mechanisms (encryption, HTTPS) and integrity mechanisms (checksums), tempting candidates to pick encryption or HTTPS when integrity verification is required.

How to eliminate wrong answers

Option A is wrong because encryption protects confidentiality, not integrity—it does not detect corruption or tampering during transfer. Option B is wrong because versioning preserves multiple versions of an object but does not verify that a given upload is intact. Option C is wrong because HTTPS secures data in transit (confidentiality and some integrity via TLS), but it does not provide end-to-end verification that the stored object matches the source file; MD5 checksums do.

Multi-Selectmedium

Which TWO actions can be performed on an active OCI Block Volume without detaching it from the compute instance? (Choose two.)

Select 2 answers
A.Change the volume from Balanced performance tier to Higher Performance tier
B.Delete the block volume while it is attached
C.Migrate the volume to a different availability domain
D.Increase the volume size (resizing)
E.Convert a block volume into a File Storage Service mount target
AnswersA, D

OCI Block Volumes support dynamic performance scaling, allowing users to modify the performance tier while the volume remains attached to an active compute instance. This capability satisfies the stem's constraint by enabling seamless resource adjustment without requiring an unmount or detach operation. By updating the volume performance unit (VPU) settings via the console or API, the underlying storage infrastructure reconfigures throughput and IOPS in real-time, ensuring that production workloads maintain continuous availability while scaling to meet fluctuating performance demands.

Why this answer

OCI Block Volumes support live resizing and dynamic performance tier adjustments without requiring volume detachment.

21
MCQeasy

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

A.Internet Gateway
B.NAT Gateway
C.Service Gateway
D.DRG
AnswerC

Service Gateways provide a dedicated virtual path within the Oracle Cloud Infrastructure backbone, enabling private connectivity to Object Storage without traversing the public internet. By routing traffic through this gateway, you satisfy the constraint of accessing resources via a private endpoint while maintaining network isolation. This mechanism ensures that data transfers remain within the internal network fabric, effectively bypassing public gateways and ensuring that your cloud architecture adheres to strict security requirements for private data exfiltration prevention.

Why this answer

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

22
MCQmedium

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

A.Archive Storage
B.Block Volume
C.File Storage
D.Object Storage
AnswerD

Object Storage provides a flat namespace architecture that excels at handling massive quantities of unstructured data, effectively satisfying the requirement for storing thousands of small files. Unlike hierarchical file systems that suffer from metadata overhead and performance degradation as directory depth increases, this service maintains consistent low-latency access times regardless of scale. By leveraging highly distributed indexing, it ensures that frequently accessed image files remain readily available, providing the necessary throughput and scalability for high-frequency retrieval operations within the cloud infrastructure.

Why this answer

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

23
MCQmedium

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

A.OCI CLI
B.API Explorer
C.Web Console
D.Terraform
AnswerC

The Oracle Cloud Infrastructure Web Console provides a visual interface that satisfies the requirement for a graphical management tool. By navigating to the Object Storage bucket details, administrators can define, edit, and monitor lifecycle policy rules directly through the browser. This environment abstracts the underlying API calls and JSON configurations, allowing users to manage data retention and archival transitions intuitively without needing to write scripts or interact with the command-line interface.

Why this answer

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

24
MCQmedium

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?

A.Archive
B.Ultra High Performance
C.Lower Cost
D.Balanced
AnswerB

Ultra High Performance volumes provide the highest level of input/output operations per second and throughput available for block storage within Oracle Cloud Infrastructure. By utilising the maximum provisioned performance tiers, this selection effectively satisfies the requirement for a high-transaction workload demanding minimal latency. This performance level ensures that the compute instance maintains consistent, low-latency access to data, which is essential for database operations that would otherwise be constrained by the throughput limitations inherent in lower-tier volume configurations.

Why this answer

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.

Exam trap

1Z0-1072-26 often tests the difference between Block Volume performance levels and Object Storage tiers — candidates may pick 'Archive' thinking it means high-performance archival, when it is actually a low-cost, low-performance Object Storage tier.

How to eliminate wrong answers

Option A is wrong because 'Archive' is not a Block Volume performance level — it is a storage tier for Object Storage (Archive Storage) used for long-term retention, not for attached block volumes. Option C is wrong because 'Lower Cost' is a performance level optimized for cost, delivering only 2 IOPS/GB and 240 KB/s per GB — far too slow for a high-transaction workload. Option D is wrong because 'Balanced' provides moderate performance (up to 25,000 IOPS, 480 MB/s) and is suitable for general-purpose workloads, not ultra-high IOPS databases.

25
MCQeasy

What is the primary purpose of OCI Object Storage?

A.High-performance cache
B.Database storage
C.Unstructured data storage
D.OS swap space
AnswerC

OCI Object Storage is designed to manage massive volumes of unstructured data by storing information as discrete objects rather than within a rigid hierarchical file system or relational database. This architecture satisfies the requirement for scalable, durable storage of binary large objects, logs, and media files. Unlike block storage, which relies on fixed-size volumes, this service provides a flat namespace that allows for virtually unlimited capacity, making it the optimal solution for data lakes and long-term archival needs within the cloud environment.

Why this answer

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.

Exam trap

1Z0-1072-26 often tests the confusion between Object Storage (unstructured, HTTP/REST) and Block Volume (block-level, attached to compute) — candidates pick 'database storage' by assuming all storage is interchangeable.

How to eliminate wrong answers

Option A is wrong because Object Storage is not a low-latency cache — caching workloads require Block Volume or in-memory services, not an HTTP object store with higher access latency. Option B is wrong because database storage requires block-level volumes (Block Volume) or managed database services; Object Storage cannot host database files with the IOPS and consistency guarantees a DBMS needs. Option D is wrong because OS swap space requires block-level, low-latency storage attached to a compute instance — Object Storage is network-based and unsuitable for swap.

Multi-Selecthard

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

Select 3 answers
A.Maximum IOPS provisioning limit
B.Object Versioning (Enabled or Disabled)
C.Encryption (Oracle-managed keys or Customer-managed keys in OCI KMS)
D.Storage Tier (Standard or Infrequent Access)
E.Automatic cross-region replication destination region
AnswersB, C, D

Object Versioning is a configurable setting during bucket creation that allows users to preserve, retrieve, and restore every version of every object stored in the bucket. By enabling this feature, you protect data against accidental deletions or overwrites, satisfying the requirement to select three valid configuration options available at the point of bucket provisioning. This mechanism maintains a history of object states, ensuring that previous iterations remain accessible even if the current version is modified or removed from the namespace.

Why this answer

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.

27
MCQhard

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

A.Volume Groups
B.Individual volume backups
C.Storage Gateway
D.Object Storage replication
E.Clone the volumes
AnswerA

Volume Groups enable the creation of crash-consistent backups across multiple block storage volumes by orchestrating snapshots simultaneously. This mechanism satisfies the requirement for a consistent point-in-time snapshot of multiple volumes, ensuring that data integrity is maintained across the entire database deployment. By grouping these volumes, you eliminate the risk of data inconsistency that would otherwise occur if snapshots were triggered sequentially. This approach is essential for complex multi-volume database configurations where application-level synchronisation is not natively managed by the underlying storage infrastructure.

Why this answer

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.

Exam trap

1Z0-1072-26 often tests the misconception that individual volume backups or clones provide cross-volume consistency, when only Volume Groups guarantee a coordinated point-in-time snapshot.

How to eliminate wrong answers

Option B is wrong because individual volume backups are taken per volume and do not guarantee a consistent point-in-time across multiple volumes, risking database corruption on restore. Option C is wrong because Storage Gateway is a hybrid storage service for connecting on-premises environments to OCI, not a mechanism for consistent multi-volume snapshots. Option D is wrong because Object Storage replication replicates objects, not block volumes, and is unrelated to database volume consistency.

Option E is wrong because cloning volumes creates copies but does not provide a coordinated point-in-time snapshot across multiple volumes.

28
MCQhard

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

A.Maps to Block Volumes
B.Maps to Object Storage buckets
C.Maps to File Storage targets
D.Maps to Archive Storage only
AnswerB

Storage Gateway functions as a file gateway by presenting a standard file system interface, such as NFS, to on-premises applications. It maps these file system directories directly to OCI Object Storage buckets, enabling seamless integration between local storage protocols and cloud-native object storage. This mechanism satisfies the requirement to bridge on-premises applications with OCI, as the gateway translates file-based I/O operations into object-based API calls, ensuring that data is persisted as objects within the designated bucket while maintaining a familiar file-level hierarchy for users.

Why this answer

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

29
MCQmedium

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

A.Balanced
B.Higher Performance
C.Lower Cost
D.Ultra High Performance
AnswerD

Ultra High Performance volumes utilise a dedicated, high-throughput architecture designed to minimise I/O latency for demanding database workloads. By providing the highest IOPS and throughput per gigabyte available within Oracle Cloud Infrastructure, this tier satisfies the requirement for high-performance block storage. It effectively eliminates the bottlenecks associated with standard tiers, ensuring consistent sub-millisecond latency for transactional applications that necessitate rapid data access. This performance level is essential for mission-critical databases where storage responsiveness directly impacts overall application throughput and system stability.

Why this answer

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

MCQmedium

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

A.An error is returned
B.A delete marker is created
C.The object is moved to Archive
D.The object is permanently deleted
AnswerB

Deleting a versioned object in Oracle Cloud Infrastructure Object Storage does not permanently remove the data; instead, it places a delete marker on the object. This mechanism satisfies the versioning constraint by ensuring that the previous object version remains intact and retrievable. The system treats this marker as the current version, effectively hiding the original data from standard list operations while maintaining the full history. This approach allows users to restore the object by deleting the marker, distinct from how Microsoft Entra ID manages identity lifecycles.

Why this answer

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

31
Multi-Selecteasy

Which TWO are common use cases for Archive Storage?

Select 2 answers
A.Real-time streaming
B.Regulatory data archiving
C.Backup retention
D.Frequent website access
E.Active database logs
AnswersB, C

Regulatory data archiving requires long-term retention of infrequently accessed information to satisfy strict compliance mandates. Archive Storage provides the necessary cost-efficiency for this scenario by utilising a low-cost, high-latency retrieval model designed for data that remains dormant for extended periods. Because these records are rarely retrieved, the trade-off of longer access times is acceptable, allowing organisations to manage massive datasets economically while ensuring data integrity and availability for future audits or legal requests.

Why this answer

Long-term regulatory compliance and data backups are standard use cases.

32
MCQeasy

An OCI administrator needs to store large amounts of unstructured data that is accessed infrequently, but must be retained for compliance purposes for at least 5 years. Data retrieval times of up to 4 hours are acceptable. Which OCI Object Storage tier should be used?

A.Object Storage Standard Tier
B.Object Storage Infrequent Access Tier
C.Archive Storage Tier
D.File Storage Service
AnswerC

Archive Storage retains infrequently accessed data for long-term compliance at the lowest cost, and its retrieval latency of up to four hours satisfies the stem's stated tolerance. Unlike Standard or Infrequent Access tiers, Archive is purpose-built for data held for years without frequent reads, matching the five-year retention requirement precisely.

Why this answer

An organization requires that all data uploaded to an Object Storage bucket must be automatically encrypted using a master encryption key managed by them in OCI Key Management (KMS), rather than Oracle-managed keys. How can this be enforced?

A.Apply an IAM policy stating that all PutObject API calls must pass customer secret keys in the header.
B.Configure the bucket during creation to use a Customer-Managed Key from OCI KMS.
C.Enable SSE-C (Server-Side Encryption with Customer-Provided Keys) on every individual file upload via CLI.
D.Write a custom OCI Functions script triggered by Object Storage events to re-encrypt objects using KMS.
AnswerB

Configuring the bucket with a Customer-Managed Key from OCI KMS ensures every uploaded object is encrypted with the organisation's own master encryption key, satisfying the requirement for customer-managed rather than Oracle-managed keys. The key is assigned at bucket creation, so encryption applies automatically to all objects without per-object configuration.

Why this answer

When creating a bucket, you can select 'Use Customer-Managed Keys' and choose your vault and master encryption key from OCI KMS.

Which TWO are true about cloning a block volume?

Select 2 answers
A.Clones must be same size
B.Clones are read-only
C.Clones are independent
D.Clones can be resized
E.Clones are linked to source
AnswersC, D

Block volume clones function as point-in-time, independent entities that maintain no dependency on the source volume’s lifecycle or data state. Once the cloning process completes, the new volume operates with its own unique metadata and storage capacity, allowing users to modify or delete the original source without affecting the clone. This architectural isolation satisfies the requirement for independent resource management, ensuring that data integrity remains preserved across separate storage objects regardless of any subsequent actions performed on the parent volume.

Why this answer

Clones are independent volumes and can be resized.

An administrator wants to create a point-in-time, space-efficient replica of an existing Block Volume within the same availability domain. Which feature should be used to achieve this instantly?

A.Block Volume Clone
B.Block Volume Backup
C.Cross-Region Replication
D.Volume Group Backup
AnswerA

A Block Volume Clone creates an instant, point-in-time copy that is space-efficient because it initially shares blocks with the source volume, diverging only as data changes. This satisfies the same-availability-domain and instant replica constraints without a full data copy.

Why this answer

A Block Volume Clone creates an instant, point-in-time copy of an existing block volume within the same availability domain. It is space-efficient because it uses copy-on-write technology, so only changed blocks consume additional storage after the clone is created. This matches the requirement for an instant, space-efficient replica in the same AD.

Exam trap

1Z0-1072-26 often tests the distinction between instant space-efficient clones and backups/replication, so candidates confuse 'point-in-time replica' with backup or cross-region copy.

How to eliminate wrong answers

Option B is wrong because a Block Volume Backup is a full point-in-time copy stored in Object Storage, not an instant space-efficient replica within the same AD, and restoring it requires creating a new volume. Option C is wrong because Cross-Region Replication asynchronously copies volumes to another region for DR, not an instant same-AD replica. Option D is wrong because a Volume Group Backup backs up a consistent set of volumes to Object Storage and is not an instant clone.

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

A.Block Volume Backup
B.RAID 0 striping
C.Object Storage replication
D.Manual file copy via SSH
AnswerA

Oracle Cloud Infrastructure Block Volume backups natively trigger crash-consistent snapshots for individual volumes, but to satisfy the production requirement for application-consistent data without risking file corruption, you must quiesce the file system and flush memory buffers to disk prior to initiating the snapshot. This direct coordination between the operating system I/O subsystem and the cloud storage API guarantees that in-flight transactions are safely persisted, thereby resolving the data integrity constraint stipulated in the production scenario.

Why this answer

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

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?

A.Archive Storage
B.Block Volume
C.Standard Object Storage
D.Infrequent Access Object Storage
AnswerA

Archive Storage provides the lowest cost per gigabyte for infrequently accessed data within Oracle Cloud Infrastructure by design, perfectly satisfying the requirement for minimal expense. Although retrieval operations require a restoration period of up to several hours before access is granted, this operational constraint aligns directly with the stipulation that retrieval times must be maintained within a few hours. This makes it the most cost-effective tier for long-term data retention where immediate access is unnecessary.

Why this answer

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

40
MCQmedium

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

A.Encryption
B.IAM policies
C.Lifecycle policies
D.Retention Rules

Which OCI storage service is best suited for hosting shared configuration files and home directories for hundreds of Linux compute instances simultaneously using the NFSv3 protocol?

A.OCI Object Storage
B.OCI File Storage Service
C.OCI Archive Storage
D.OCI Block Volume
AnswerB

OCI File Storage satisfies the requirement for a shared file system accessible by hundreds of Linux compute instances simultaneously because it implements the Network File System version 3 (NFSv3) protocol. This fully managed service provides a distributed file system that can be mounted concurrently across multiple Oracle Cloud Infrastructure compute nodes, making it the ideal architecture for sharing common configuration files and user home directories without file-locking conflicts or protocol mismatches.

Why this answer

OCI File Storage Service provides a shared, POSIX-compliant NFSv3 file system that can be mounted concurrently by hundreds of Linux compute instances, making it ideal for shared configuration files and home directories. It supports NFSv3 and NFSv4.1 and scales to thousands of clients per file system. This is the only OCI storage service designed for concurrent shared file access over NFS.

Exam trap

1Z0-1072-26 often tests the confusion between block, file, and object storage—candidates must recognize that NFSv3 multi-client sharing maps only to File Storage, not Block or Object Storage.

How to eliminate wrong answers

Option A is wrong because OCI Object Storage is an HTTP/REST-based object store, not a POSIX file system, and cannot be mounted natively via NFSv3 for shared home directories. Option C is wrong because Archive Storage is a cold-tier object storage class for long-term retention, not a shared file system. Option D is wrong because OCI Block Volume is a raw block device attached to a single instance (or shared only via specific clustered configurations), not a multi-client NFS file system.

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

A.Public keys
B.IAM policies
C.OCI Vault
D.Encryption Gateway
AnswerC

Oracle Cloud Infrastructure (OCI) Vault is the correct feature because it satisfies the requirement to use customer-managed encryption keys for Object Storage buckets. OCI Vault integrates natively with Object Storage, allowing administrators to centrally manage and control the master encryption keys used to secure data at rest. By leveraging Vault, you maintain full lifecycle control over your keys—including rotation, creation, and scheduled deletion—instead of relying on default Oracle-managed keys, thereby fulfilling stringent security and compliance mandates.

Why this answer

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

A team is using OCI File Storage Service and needs to protect against accidental deletion of files by end users. Which feature should be implemented?

A.FSS Snapshots
B.Object Storage Lifecycle Policies
C.FSS Object Versioning
D.Block Volume Volume Groups
AnswerA

File Storage Service (FSS) snapshots provide a read-only, point-in-time view of a file system that can be scheduled or created manually to satisfy the requirement of protecting against accidental end-user deletion. Because snapshots are immutable and stored independently of the active file system data, users cannot modify or delete the snapshot contents even if they inadvertently remove the original files from the mount target. This mechanism allows administrators to effortlessly restore the exact state of the data as it existed prior to the user error.

Why this answer

File Storage Service supports snapshots, which are read-only, point-in-time versions of a file system that allow users to recover accidental deletions.

You are configuring a Lifecycle Policy for an Object Storage bucket. You want to automatically move objects older than 30 days to Archive Storage. What is the correct rule configuration?

A.Use the 'Delete' action with a 30-day threshold.
B.Use the 'Move' action to a new bucket.
C.Use the 'Archive' action with a 30-day threshold.
D.Use the 'Restore' action.
AnswerC

Object Storage Lifecycle Policies natively support transitioning objects directly to Archive Storage based on an age-based time threshold. Configuring the rule to target objects older than 30 days using the Archive action precisely satisfies the explicit requirement in the stem to automate the migration of data to the long-term cold storage tier without manual intervention.

Why this answer

The lifecycle policy uses JSON-based rules to define action, name filter, and age threshold.

MCQeasy

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

A.Creating an immediate, independent volume
B.Backup automation
C.Reducing storage usage
D.Moving to another region
AnswerA

Cloning a block volume utilises point-in-time metadata pointer architecture to instantly provision a new storage entity without requiring a full data copy operation. This satisfies the constraint of creating an immediate, independent volume because the storage service references existing data blocks instantaneously, allowing read and write operations to commence straight away on a fully decoupled resource, regardless of the source volume size.

Why this answer

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.

Exam trap

The trap here is confusing 'clone' with 'backup' — candidates see 'copy of a volume' and default to backup automation, missing that a clone is an immediately usable, independent volume rather than a recovery artifact.

How to eliminate wrong answers

Option B is wrong because backup automation is the role of OCI Block Volume Backup Policies and the Backup service, not cloning — a clone is a live, usable volume, not a scheduled backup artifact. Option C is wrong because a clone consumes its own block storage capacity equal to the source volume's provisioned size; it does not deduplicate or reduce storage usage. Option D is wrong because block volume clones are created within the same region and availability domain as the source; moving data to another region requires cross-region replication or backup copy, not a clone.

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

Object versioning in Oracle Cloud Infrastructure Object Storage satisfies the requirement to retain multiple variants of an object within the same bucket. When this feature is enabled, uploading a new object with the same name as an existing one automatically creates a new version instead of overwriting the original data, generating a unique version ID for each iteration. This mechanism protects critical datasets against accidental overwrites or malicious deletions, allowing administrators to retrieve previous states directly from the storage bucket without external backups.

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

Oracle Cloud Infrastructure (OCI) Archive Storage is specifically designed for long-term data retention where access is infrequent, satisfying the administrator's requirement for a cost-effective archiving strategy. To enforce this intended use case for cold data, OCI imposes a strict minimum storage duration commitment of 90 days. If data is deleted or overwritten before this 90-day threshold has elapsed, a pro-rated early deletion charge is applied, which directly addresses the cost-optimisation constraint inherent in long-term data archiving planning.

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.

Which TWO of the following can prevent a bucket from being deleted?

Select 2 answers
A.Public access allowed
B.Bucket contains objects
C.Versioning enabled
D.Retention rules
E.Bucket encryption
AnswersB, D

Object Storage buckets cannot be deleted while they still contain data or multipart uploads, as a safety mechanism to prevent accidental data loss. To satisfy the requirement of preventing bucket deletion, you must ensure the bucket is not empty. Therefore, deleting a bucket requires either manually removing all contained objects and object versions first, or configuring lifecycle rules to purge the contents, because the service API explicitly rejects deletion requests for non-empty buckets to safeguard against irreversible operational mistakes.

Why this answer

Retention rules and non-empty status prevent bucket deletion.

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

A.Customizable IOPS and throughput
B.Always fixed price
C.Mandatory for boot volumes
D.Only for production
AnswerA

OCI Block Volume performance tiers let you provision IOPS and throughput independently of capacity, up to 300,000 IOPS and 4,800 MB/s per volume. This satisfies the stem's requirement for a main advantage: workloads needing high performance without large storage avoid paying for unused capacity, unlike fixed-performance alternatives.

Why this answer

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.

Exam trap

1Z0-1072-26 often tests the assumption that Block Volume performance is fixed or tied only to size — candidates miss that tiers allow independent, adjustable IOPS/throughput selection.

How to eliminate wrong answers

Option B is wrong because pricing varies by performance tier and provisioned capacity — it is not always a fixed price; higher tiers cost more. Option C is wrong because performance tier selection is not mandatory for boot volumes; boot volumes have their own defaults and can use different tiers, but it is not a requirement. Option D is wrong because performance tiers are available for any workload, not restricted to production — dev/test volumes can also use them.

A.Cross-Region Replication
B.Object Versioning
C.Object Storage Lifecycle Management
D.Bucket Retention Rules
AnswerB

Object Versioning satisfies the requirement to protect against accidental data loss by maintaining multiple variants of an object within a single bucket. When this feature is enabled, OCI assigns a unique version ID to every object update or deletion, ensuring that previous states remain accessible rather than being permanently overwritten. This mechanism provides a robust recovery path for overwritten data, effectively decoupling the current object state from its historical lifecycle and preventing irreversible data destruction during routine management tasks.

MCQhard

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

A.Data is lost if not backed up
B.Data remains intact
C.Data is encrypted for migration
D.Data is deleted
AnswerB

Detaching a block volume in Oracle Cloud Infrastructure simply unmounts the storage from the compute instance without triggering a deletion process. Because the volume exists as a persistent, independent resource decoupled from the lifecycle of the virtual machine, the underlying data blocks remain stored within the storage pool. This mechanism ensures that the volume satisfies the constraint of data persistence, allowing the storage to be reattached to a different instance or re-mounted later without any loss of information.

Why this answer

The correct answer is B because 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.

1Z0-1072-26 often tests the persistence of block storage; candidates may confuse detach with delete, or assume that detaching requires backup to avoid data loss, which is incorrect.

How to eliminate wrong answers

Option A is wrong because detaching a Block Volume does not cause data loss; data loss would only occur if the volume itself were deleted or if the underlying storage failed, which is mitigated by OCI's durability. Option C is wrong because detaching does not trigger encryption for migration; encryption is a separate configuration (OCI Block Volumes are encrypted by default at rest, but detaching does not change encryption state). Option D is wrong because detaching does not delete data; deletion is a separate, explicit action (e.g., terminating the volume).

Which THREE are characteristics of Object Storage lifecycle rules?

Select 3 answers
A.Automated execution
B.Supports database commands
C.Real-time trigger
D.JSON-based configuration
E.Name-based filtering
AnswersA, D, E

Lifecycle rules operate as an automated background process within Oracle Cloud Infrastructure Object Storage, eliminating the need for manual intervention to manage data retention. By defining policies based on object age or prefix, the service autonomously transitions data to archive tiers or deletes expired objects. This mechanism directly satisfies the requirement for automated execution, ensuring that storage costs are optimised and data governance policies are enforced consistently without requiring administrators to manually trigger scripts or perform recurring management tasks.

Why this answer

JSON-based, filterable by name, and target-specific actions.
