Oracle 1Z0-1072-25 Exam Syllabus Topics:

Topic
Details

Topic 1

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 2

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 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 (Q11-Q16):

NEW QUESTION # 11
Which statement is TRUE about restoring a volume from a block volume backup in the Oracle Cloud Infrastructure (OCI) Block Volume service?

A. You can restore a volume from any full volume backup but not from an incremental backup.
B. You can only restore a volume to the same availability domain in which the original block volume resides.
C. You can restore a block volume backup to a larger volume size.
D. You can restore only one volume from a manual block volume backup.

Answer: C

Explanation:
Restoring a block volume from a backup in OCI provides flexibility and options for scaling and recovery:
Restoring to a Larger Volume Size: When restoring a block volume from a backup, you have the option to restore it to a volume that is larger than the original. This is particularly useful if you anticipate needing more storage capacity after the restore.
Full and Incremental Backups: OCI supports both full and incremental backups. You can restore from any backup type, which makes it possible to restore data efficiently depending on the backup strategy used.
Multiple Restores: Multiple volumes can be restored from a single backup, providing flexibility in disaster recovery scenarios.
Availability Domain: The restored volume can be created in any availability domain within the same region, not necessarily the same one where the original volume was located.
Relevant OCI Documentation:
Block Volume Service Overview
Restoring a Block Volume
These references explain the process and options available for restoring block volumes from backups.

NEW QUESTION # 12
Why was SSH still possible after port 22 was removed from the Security Lists?

A. The VNIC of that compute instance is attached to a Cluster Network.
B. The VNIC of that compute instance is attached to a Network Security Group (NSG).
C. The VCN where that compute instance resides still has an Internet Gateway.
D. The VCN where that compute instance resides still has a route rule.

Answer: B

Explanation:
Even after removing port 22 from the Security Lists, SSH was still possible because the Virtual Network Interface Card (VNIC) of the compute instance is attached to a Network Security Group (NSG).
NSGs: NSGs provide a more flexible and granular way to manage security rules compared to Security Lists. They allow you to apply security rules directly to VNICs associated with resources such as compute instances. If an NSG allows traffic on port 22, SSH will still be possible, regardless of the Security List settings.

NEW QUESTION # 13
Which statement accurately describes the key features and benefits of OCI Confidential Computing?

A. It provides automatic scalability and load balancing capabilities.
B. It enables users to securely store and retrieve data by using distributed file systems.
C. It optimizes network performance through advanced routing algorithms.
D. It encrypts and isolates in-use data and the applications processing that data.

Answer: D

Explanation:
OCI Confidential Computing is a security feature designed to protect data in use. This is particularly important for sensitive workloads where data must be secured not only when at rest or in transit but also while being processed.
Encrypts and Isolates In-Use Data: OCI Confidential Computing ensures that data and the applications processing it are isolated from the underlying infrastructure. This means that even if the infrastructure is compromised, the in-use data remains secure. The technology typically leverages secure enclaves or other hardware-based isolation mechanisms to achieve this.
Other Options:
Optimizing Network Performance (A), Automatic Scalability and Load Balancing (B), and Secure Data Storage (D) are important features, but they are not related to the core capabilities of Confidential Computing, which focuses on in-use data protection.
Relevant OCI Documentation:
OCI Confidential Computing Overview
This documentation provides a detailed explanation of how OCI Confidential Computing works and its benefits for securing sensitive data during processing.

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

Answer: B

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.
Reference:
Oracle Cloud Infrastructure Documentation: File Storage Service Overview

NEW QUESTION # 15
Which statement is true about instance configurations and instance pools in OCI?

A. You cannot reuse the same instance configuration for multiple instance pools.
B. You can delete an instance configuration if it is associated with an instance pool.
C. An instance pool can have multiple instance configurations associated with it.
D. You can only delete an instance configuration if it is not associated with any instance pool.

Answer: D

Explanation:
Instance configurations and instance pools are used in OCI to manage groups of instances collectively:
Deleting Instance Configurations: An instance configuration cannot be deleted if it is currently associated with an instance pool. You must first disassociate or delete the instance pool before you can delete the instance configuration.
Reusing Instance Configurations: You can reuse the same instance configuration for multiple instance pools, which allows you to deploy identical groups of instances in different contexts.
Instance Pools: A single instance pool can only be associated with one instance configuration, ensuring uniformity across the instances in the pool.
Relevant OCI Documentation:
Instance Configuration Overview
Instance Pools Overview
These references explain how to manage instance configurations and pools, including the rules for deletion.
