The Oracle 1Z0-1072-25 exam is part of the Oracle Cloud, Oracle Cloud Infrastructure certification track and leads to the Oracle Cloud Infrastructure 2025 Architect Associate credential. It is designed for candidates who want to validate their ability to design and support OCI solutions using core cloud services. This exam matters because it confirms practical knowledge in key infrastructure areas that are central to modern Oracle Cloud deployments.
Exam Topics and Approximate Weightage
| # | Exam Topics | Sub-Topics | Approximate Weightage (%) |
|---|---|---|---|
| 1 | Compute | Instances and shapes, autoscaling, instance configuration, bare metal and virtual machines | 30% |
| 2 | Networking | VCN design, subnets and routing, security lists and network security groups, load balancing and connectivity | 30% |
| 3 | Storage | Block volumes, object storage, file storage, backup and recovery options | 20% |
| 4 | Identity and Access Management | Compartments, users and groups, policies, dynamic groups and authentication controls | 20% |
This exam tests more than basic memorization. Candidates must understand OCI concepts, service relationships, and how to apply them in real deployment scenarios. It measures your ability to choose the right compute, networking, storage, and IAM options while working with practical cloud architecture decisions.

Which OCI feature should be used to ensure that communication between database servers and OCI Object Storage is secure?
To ensure secure communication between database servers and OCI Object Storage, you should use a Service Gateway. A Service Gateway enables instances in your VCN to privately access OCI services like Object Storage without traversing the public internet.
Security: The traffic between your database servers and Object Storage remains within the Oracle network, providing a secure and high-performance connection.

Which TWO statements are NOT correct regarding the Oracle Cloud Infrastructure (OCI) burstable instances?
The following statements about OCI burstable instances are NOT correct:
A . Burstable instances cost less than regular instances: This is incorrect because burstable instances are not necessarily cheaper; the cost depends on the baseline utilization. While they allow for cost efficiency when running at a lower CPU baseline, they can become more expensive if frequently bursting above the baseline.
B . Burstable instances are charged according to the baseline OCPU: This is incorrect because burstable instances are billed based on actual OCPU usage, which includes both baseline and burst usage. If an instance frequently operates above its baseline, the cost will reflect this higher usage.
Correct Concepts:
C . Burstable instances can temporarily use more CPU than their baseline if the average CPU utilization is below the baseline.
D . Baseline utilization is a fraction of each CPU core, which determines the level of consistent performance available without bursting.

Which OCI Object Storage tier is suitable for storing the backup to minimize cost while meeting the requirements of immediate accessibility and retention of 31 days?
The Infrequent Access tier in OCI Object Storage is suitable for storing backups that need to be immediately accessible and retained for a specific period, such as 31 days, while also minimizing costs. This tier offers a balance between cost and accessibility, charging lower storage costs compared to the Standard tier but still allowing quick access to the data.
Use Case: The Infrequent Access tier is designed for data that is not frequently accessed but must remain readily available when needed, making it ideal for backup storage.

Why was SSH still possible after port 22 was removed from the Security Lists?
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.

What happens to the performance level of a volume when it is detached from an instance?
In Oracle Cloud Infrastructure (OCI), when a block volume is detached from an instance, its performance level is automatically adjusted to the 'Lower Cost' tier, which provides 0 VPUs (Volume Performance Units) per GB. This adjustment helps reduce costs when the block volume is not actively being used by a compute instance.
Key Points:
Volume Performance Levels: OCI offers various performance tiers for block volumes, including 'Higher Performance,' 'Balanced,' and 'Lower Cost.' These tiers determine the level of IOPS (Input/Output Operations Per Second) and throughput available to the volume.
Automatic Adjustment: When a block volume is detached from an instance, OCI automatically optimizes the cost by switching the volume to the 'Lower Cost' performance tier. This tier offers minimal performance, suitable for data that is not actively accessed.
Cost Management: This automatic adjustment is beneficial for managing costs, as it prevents users from incurring unnecessary charges for higher performance levels when the volume is not in use.
