1Z0-1072-26 Storage Practice Test 3 — 15 Questions

Question 1

Which TWO of the following statements about Storage Gateway are accurate?

Accepted Answer

It converts files to objects. Option A is correct because AWS Storage Gateway's File Gateway presents SMB/NFS file shares to on-premises clients while storing the data as objects in Amazon S3, effectively converting file-level access into object storage. Option C is correct because Storage Gateway appliances (File, Volume, and Tape Gateways) maintain a local cache on the gateway host to provide low-latency access to frequently used data while asynchronously uploading to AWS. Option B is not a documented automatic feature of Storage Gateway, as compression is not performed transparently by the service. Option D is incorrect because POSIX support is not a defining characteristic of Storage Gateway; its file shares use SMB/NFS protocols rather than exposing a POSIX-compliant filesystem. Option E is incorrect because Storage Gateway is not a block-level device in the sense of a raw block storage service like EBS; even Volume Gateway exposes iSCSI block volumes but the service as a whole is a hybrid storage appliance, and the statement as written mischaracterizes it.

Answer

It performs automatic compression

Answer

It provides POSIX support

Answer

It is a block-level device

Question 2

A financial services company runs a latency-sensitive trading application on a VM.Standard.E4.Flex instance in the Oracle Cloud Infrastructure (OCI) Ashburn region. The application demands the highest possible IOPS with consistent sub-millisecond latency and must remain available even if a single Availability Domain (AD) experiences a power failure. The storage architect is evaluating Block Volume performance options. Which TWO actions will meet these requirements? (Choose two.)

Accepted Answer

Attach a Block Volume configured with the Ultra High Performance level to the instance.. Ultra High Performance Block Volumes deliver the required IOPS and sub-millisecond latency, and they must be attached to an instance in the same Availability Domain. Together, these two choices satisfy the performance and locality requirements. The other options either violate attachment constraints or provide the wrong type of redundancy for an AD failure.

Answer

Enable the Block Volume's built-in replication to a second Availability Domain within the same region.

Answer

Create the Block Volume in an AD different from the compute instance's AD to provide cross-AD redundancy.

Answer

Configure a cross-region replication schedule for the Block Volume to a second region.

Question 3

A healthcare provider runs a critical Oracle Database on an OCI Compute instance. The database uses a Block Volume that must be backed up every night without impacting performance. The backup must be retained for 30 days and then automatically deleted. The database administrator wants to ensure that the backup captures a consistent state of the volume. What should the administrator do?

Accepted Answer

Create a volume backup policy that runs daily, retains backups for 30 days, and enable application-consistent backup by quiescing the database before the backup.. A volume backup policy automates daily backups with a 30-day retention, and quiescing the database ensures application consistency. This combination meets the requirements for performance, retention, and consistency. The other options either lack automation, do not provide point-in-time backups, or do not address consistency.

Answer

Use the OCI Block Volume clone feature to create a clone daily and delete clones older than 30 days.

Answer

Enable cross-region replication for the volume and configure a 30-day retention on the replicated volume.

Answer

Schedule a script that creates a manual volume backup daily and uses a cron job to delete backups older than 30 days.

Question 4

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?

Accepted Answer

OCI File Storage Service. 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.

Answer

OCI Object Storage

Answer

OCI Archive Storage

Answer

OCI Block Volume

Question 5

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?

Accepted Answer

Block Volume Clone. 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.

Answer

Block Volume Backup

Answer

Cross-Region Replication

Answer

Volume Group Backup

Question 6

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?

Accepted Answer

Configure the bucket during creation to use a Customer-Managed Key from OCI KMS.. When creating a bucket, you can select 'Use Customer-Managed Keys' and choose your vault and master encryption key from OCI KMS.

Answer

Apply an IAM policy stating that all PutObject API calls must pass customer secret keys in the header.

Answer

Enable SSE-C (Server-Side Encryption with Customer-Provided Keys) on every individual file upload via CLI.

Answer

Write a custom OCI Functions script triggered by Object Storage events to re-encrypt objects using KMS.

Question 7

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?

Accepted Answer

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

Answer

Object Storage Lifecycle Policies

Answer

FSS Object Versioning

Answer

Block Volume Volume Groups

Question 8

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?

Accepted Answer

Archive Storage Tier. OCI Archive Storage is designed for data that is infrequently accessed and requires long retention periods, offering the lowest storage cost with a time-to-first-byte retrieval time of up to 4 hours.

Answer

Object Storage Standard Tier

Answer

Object Storage Infrequent Access Tier

Answer

File Storage Service

Question 9

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 10

You are configuring an Object Storage bucket and want to ensure that if an object is accidentally overwritten or deleted, previous versions can still be retrieved. Which feature should you enable?

Question 12

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?

Accepted Answer

Mount the file system on a compute instance and use standard Linux tools such as 'du' or quota management.. 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.

Answer

View the Storage Consumption metric in OCI Monitoring service aggregated by directory path.

Answer

Check the Object Storage Metrics explorer for FSS bucket utilization.

Answer

Enable FSS Analytics in the OCI Console under Storage Administration.
