1Z0-1072-26 Practice Test 34 — 15 Questions

Question 1

A company is running an enterprise application on OCI that requires high IOPS and low latency for its database files. The administrator needs to attach a block volume that can dynamically scale performance beyond its default capacity limits without having to detach the volume. Which Block Volume performance level should be selected?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Higher Performance. Higher Performance provides the highest IOPS and throughput per GB, and volumes can be dynamically scaled up to higher performance tiers or resized without downtime.

Answer

Lower Cost

Answer

Ultra High Performance

Answer

Balanced

Question 2

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 3

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.

Question 4

An administrator has created a File Storage Service (FSS) file system in a private subnet. Developers need to mount this file system on compute instances across three different availability domains within the same region. What is the correct way to configure network access for FSS?

Accepted Answer

Deploy a mount target in one subnet and configure security lists to allow NFS traffic from instances in all required subnets.. FSS is regional and can be mounted across availability domains in the same region, provided that mount targets are accessible via appropriate security lists and subnet routes.

Answer

Attach the Block Volume to multiple instances simultaneously across availability domains.

Answer

Create a separate FSS file system in each availability domain and peer them.

Answer

Use an OCI FastConnect circuit to route NFS traffic between availability domains.

Question 5

A Block Volume backup failed. Which is the most likely reason?

Accepted Answer

Insufficient IAM permissions. Volume backups can fail if the volume is in a state that prevents snapshotting, or due to IAM permissions.

Answer

Bucket size limit

Answer

FastConnect is down

Answer

File system is mounted

Question 6

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 7

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 8

Which THREE configurations are required for a functioning File Storage Service mount?

Accepted Answer

Export options. A mount target, a subnet, and export options are essential.

Answer

Public internet gateway

Answer

Block volume attachment

Question 9

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 10

You need to configure an Object Storage lifecycle policy to automatically transition objects from the Standard tier to the Infrequent Access tier after 30 days, and then delete them after 365 days from creation. How should the rule be defined?

Accepted Answer

Create a single rule with transition after 30 days to Infrequent Access and deletion after 365 days.. Lifecycle rules use offset values based on object creation time. Transition and deletion rules can be chained by specifying days relative to the object's age.

Answer

Configure an event rule in OCI Events Service to trigger a function that modifies the storage tier after 30 days.

Answer

Set the bucket storage policy to automatically purge objects after 365 days and use Object Versioning to handle the 30-day tier shift.

Answer

Create two separate rules: one for transition at 30 days and another rule evaluated independently for deletion at 335 days.

Question 11

You are experiencing high latency on your FSS mount. What should you check first?

Accepted Answer

Network Security List rules. Network security lists and mount options are common culprits for FSS latency.

Answer

Block volume size

Answer

Object storage versioning

Answer

Bucket policies

Question 12

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 13

Which tier of Block Volume performance allows you to dynamically adjust the IOPS/GB?

Accepted Answer

Balanced. Balanced and Higher Performance tiers allow dynamic adjustment of performance settings.

Answer

Lower Cost
