Oracle 1Z0-1072-25 Exam Syllabus Topics:

Topic
Details

Topic 1

Identity and Access Management (IAM): This domain validates skills of security architects implementing granular access controls, emphasizing IAM policy creation, compartment organization, and dynamic group configuration. It covers identity domain management, network source restrictions, and tag-based access mechanisms to enforce least-privilege principles across OCI resources

Topic 2

Storage: Designed for storage administrators managing enterprise data solutions, this section tests proficiency in deploying Block
File
Object Storage with lifecycle management, cross-region replication, and tiered storage strategies. It includes configuring volume groups, snapshots, versioning, and security controls while analyzing storage performance metrics and cost optimization techniques.

Topic 3

Networking: Targeting network architects designing secure cloud architectures, this domain focuses on Virtual Cloud Network (VCN) implementation, including subnet design, IP address management, and routing through gateways (NAT, service, internet). It assesses expertise in VPN
FastConnect deployment, DNS configuration, load balancer setup, and advanced tools like Network Path Analyzer for troubleshooting latency or connectivity issues.

Topic 4

Compute: This section measures skills of cloud architects responsible for designing scalable and resilient infrastructure, covering compute instance configuration, autoscaling policies, and OS management. It evaluates understanding of OCI compute image options, infrastructure maintenance processes, and strategies for optimizing instance performance across availability domains.

Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q14-Q19):

NEW QUESTION # 14
What would be the total meteredBytes shown by the File Storage service after the hourly update cycle is complete when you overwrite 0.5 GB of a 1 GB file?

A. 1 GB
B. 2.5 GB
C. 0.5 GB
D. 1.5 GB

Answer: D

Explanation:
In Oracle Cloud Infrastructure (OCI) File Storage, when you overwrite a portion of a file, the service does not immediately reclaim the space occupied by the previous version of the file. The total meteredBytes reflects both the original data and the new data written.
Scenario Explanation: You start with a 1 GB file. When you overwrite 0.5 GB of this file, the file system retains both the 0.5 GB of the original file and the new 0.5 GB you wrote.
Calculation: The original 1 GB file contributes 1 GB to meteredBytes. When 0.5 GB is overwritten, the total usage becomes 1.5 GB (1 GB original + 0.5 GB new).
Thus, after the hourly update cycle, the total meteredBytes shown by the File Storage service will be 1.5 GB.

NEW QUESTION # 15
Which of the following is a valid RFC 1918 CIDR prefix that can be used for creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN)?

A. 192.268.0.0/24
B. 0.0.0.0/0
C. 192.168.0.0/16
D. 10.0.0.0/8

Answer: C,D

Explanation:
RFC 1918 defines IP address ranges that are reserved for private networks, which cannot be routed on the public internet. In Oracle Cloud Infrastructure (OCI), these private IP address ranges can be used to create Virtual Cloud Networks (VCNs). The valid RFC 1918 CIDR prefixes include:
192.168.0.0/16: A private IP range often used in home networks.
10.0.0.0/8: A large private IP range commonly used in enterprise networks.
Invalid Options:
B . 0.0.0.0/0: This CIDR represents all IP addresses and is not a valid private IP range.
C . 192.268.0.0/24: This is not a valid IP address range as the octet "268" is outside the allowable range of 0-255.
Reference:
Oracle Cloud Infrastructure Documentation: VCN Overview
RFC 1918: Address Allocation for Private Internets

NEW QUESTION # 16
Which statement is true about pre-authenticated requests?

A. You cannot edit a pre-authenticated request.
B. Deleting a pre-authenticated request does not revoke access.
C. Pre-authenticated requests can be used to delete buckets.
D. You need to provide your OCI credentials to the partner company.

Answer: A

Explanation:
In Oracle Cloud Infrastructure (OCI), pre-authenticated requests (PARs) allow users to grant access to specific objects in Object Storage without requiring the recipient to have an OCI account or credentials. This feature is useful for sharing objects securely without exposing broader access.
Cannot Edit a PAR: Once a pre-authenticated request is created, you cannot edit it. If you need to change the settings, such as the expiration date or the object being shared, you must delete the existing PAR and create a new one.
Other Statements:
Deleting a PAR does indeed revoke access immediately, contradicting option B.
Providing OCI credentials (C) is not required for using PARs. The purpose of PARs is to avoid sharing credentials.
Deleting Buckets (D): PARs are designed for accessing objects, not for administrative actions like deleting buckets.
Relevant OCI Documentation:
Managing Pre-Authenticated Requests
This reference outlines the features and limitations of pre-authenticated requests, including the inability to edit them once created.

NEW QUESTION # 17
Which statement is NOT true about the Oracle Cloud Infrastructure (OCI) Object Storage service?

A. Object Storage resources can be shared across tenancies.
B. Object Versioning is enabled at the namespace level.
C. Immutable option for data stored in Object Storage can be set via retention rules.
D. Object lifecycle rules can be used to archive or delete objects.

Answer: A

Explanation:
Oracle Cloud Infrastructure (OCI) Object Storage is a scalable, highly durable service that allows you to store any type of data in a secure and cost-effective manner. The correct and incorrect statements regarding OCI Object Storage are as follows:
A . Immutable Option: You can indeed set an immutable option for data in Object Storage using retention rules. This feature ensures that once data is written, it cannot be modified or deleted until the retention period expires, making it ideal for regulatory compliance.
C . Object Lifecycle Rules: Object lifecycle policies allow you to automate the archiving or deletion of objects based on their age or other criteria, helping manage storage costs and data retention efficiently.
D . Object Versioning: Versioning is enabled at the bucket level, not the namespace level. However, once enabled for a bucket, it helps retain, retrieve, and restore every version of every object stored in that bucket.
B . Object Storage Sharing Across Tenancies: This statement is not true. OCI Object Storage buckets and objects are specific to a tenancy and cannot be shared across different tenancies directly. Access to Object Storage resources is controlled within a single tenancy through IAM policies.
Relevant OCI Documentation:
OCI Object Storage Overview
Object Lifecycle Management
These references provide details on how Object Storage functions and the features available.

NEW QUESTION # 18
How will moving a database instance to a different compartment impact user access?

A. IAM policies are not tied to compartments.
B. Access will be revoked for all users.
C. Compartments prevent resource movement.
D. Compartments are not covered by IAM policies.

Answer: B

Explanation:
In Oracle Cloud Infrastructure (OCI), when you move a database instance to a different compartment, the following impact on user access occurs:
Impact of Moving Resources: When you move a resource, like a database instance, to a different compartment, the IAM policies that grant access to that resource in the original compartment no longer apply. This effectively revokes access for users or groups unless equivalent policies are in place in the new compartment.
Restoring Access: To restore access, you would need to create new IAM policies in the destination compartment that grant the necessary permissions to the users or groups who need access.
Relevant OCI Documentation:
Managing Compartments
Moving Resources
These resources provide detailed steps on how compartment changes impact resource access and management.
