Oracle 1Z0-1072-25 Exam Syllabus Topics:

Topic
Details

Topic 1

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 2

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.

Topic 3

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 4

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

Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q37-Q42):

NEW QUESTION # 37
What happens to the performance level of a volume when it is detached from an instance?

A. The performance level is adjusted to Balanced.
B. The performance level is adjusted to Lower Cost (0 VPUs/GB).
C. The performance level is adjusted to Higher Performance.
D. The performance level remains unchanged.

Answer: B

Explanation:
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.

NEW QUESTION # 38
Which statement accurately describes the key features and benefits of OCI Confidential Computing?

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

Answer: B

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 # 39
Which authentication option should you use to ensure third-party APIs communicate with OCI resources?

A. API Signing Key
B. Auth Tokens
C. SSH Key Pair with 2048-bit algorithm
D. OCI Username and Password

Answer: A

Explanation:
When ensuring that third-party APIs communicate securely with OCI resources, the appropriate authentication option is API Signing Key.
API Signing Key: This method uses an RSA key pair to authenticate and sign API requests. The API signing key provides a secure and reliable way to ensure that the API requests to OCI are coming from an authorized source. It is commonly used for programmatic access to OCI services.
Other Options:
SSH Key Pair: Primarily used for secure shell access to compute instances, not for API authentication.
Auth Tokens: Typically used for authentication in environments where APIs don't support the API Signing Key, such as OCI CLI or SDKs.
OCI Username and Password: Generally used for the Console login, not for securing API communications.
Relevant OCI Documentation:
API Signing Key Authentication
This documentation provides details on using API Signing Keys for secure API communication in OCI.

NEW QUESTION # 40
Which is NOT a valid action within the Oracle Cloud Infrastructure (OCI) Block Volume service?

A. Expanding an existing volume in place with offline resizing.
B. Restoring from a volume backup to a larger volume.
C. Cloning an existing volume to a new, larger volume.
D. Attaching a block volume to an instance in a different availability domain.

Answer: D

Explanation:
In Oracle Cloud Infrastructure (OCI), block volumes are designed to be highly flexible and can be used in various ways:
A . Restoring from a volume backup to a larger volume: This is supported and allows for resizing during the restoration process.
B . Cloning an existing volume to a new, larger volume: You can clone a block volume and specify a larger size for the new volume.
C . Expanding an existing volume in place with offline resizing: OCI allows you to increase the size of an existing block volume without needing to take it offline.
Option D is NOT valid because block volumes can only be attached to compute instances within the same availability domain. Cross-availability domain attachment of block volumes is not supported directly.

NEW QUESTION # 41
Which policy would you write to provide admin access to all three of your existing admin groups for a shared Test compartment?

A. Allow all-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
B. Allow group any-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
C. Allow any-user to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
D. Allow dynamic-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'

Answer: A

Explanation:
In Oracle Cloud Infrastructure (OCI), policies are written to define permissions for user groups. The correct policy to provide admin access to all three existing admin groups in a shared compartment (in this case, the "Test" compartment) would be:
"Allow all-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'".
"Allow all-group": Grants access to all groups.
"to manage all-resources": Specifies full access permissions (manage includes all CRUD operations).
"in compartment Test": Limits the scope of the policy to the "Test" compartment.
"where request.principal.group.tag.EmployeeGroup.Role='Admin'": Adds a condition to restrict this admin-level access to only groups tagged with the role 'Admin'.
This policy ensures that only users in the groups tagged as Admin will be allowed to manage resources in the Test compartment, making it the most suitable choice for providing admin access.
