Oracle 1Z0-1072-25 Exam Syllabus Topics:

TopicDetails
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
  • 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
  • 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
  • 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 (Q36-Q41):

NEW QUESTION # 36
What happens to the performance level of a volume when it is detached from an instance?

  • A. The performance level remains unchanged.
  • 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 is adjusted to Balanced.

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 # 37
How many capacity reservations would you create to meet the requirement for high availability and distribution across Availability Domains?

  • A. One
  • B. Four
  • C. Two
  • D. Three

Answer: D

Explanation:
In Oracle Cloud Infrastructure (OCI), to ensure high availability and distribution across Availability Domains (ADs), the recommended approach is as follows:
Capacity Reservations for High Availability: To achieve high availability, especially across all three Availability Domains in a region, you should create three capacity reservations. Each reservation corresponds to one AD, ensuring that your instances or resources are evenly distributed and resilient to AD-level failures.
Why Three: This setup provides redundancy and load distribution across the ADs, meeting the high availability requirements.
Relevant OCI Documentation:
Capacity Reservations
This document outlines how to create and manage capacity reservations to meet high availability and fault tolerance requirements.


NEW QUESTION # 38
Which authentication option should you use to ensure third-party APIs communicate with OCI resources?

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

Answer: D

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 # 39
Which is NOT a necessary step to complete this setup for instance principals?

  • A. Deploy the application and the SDK to all the instances that belong to the dynamic group.
  • B. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
  • C. Create a dynamic group with matching rules to specify which instances can make API calls against services.
  • D. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.

Answer: D

Explanation:
Instance principals in OCI allow compute instances to directly make API calls against OCI services without requiring a user account. To set up instance principals, the following steps are necessary:
A . Deploy the application and SDK: The application running on the instances must use the OCI SDK or CLI to make API calls.
B . Create a dynamic group: Define a dynamic group with matching rules to identify which instances can use the API permissions.
C . Create a policy: Write an IAM policy that grants the dynamic group the necessary permissions to access services.
Option D is NOT necessary because instances in a dynamic group use instance principals to authenticate and do not require Auth Tokens, which are used for user authentication with APIs.

NEW QUESTION # 40
Which OCI feature should be used to ensure that communication between database servers and OCI Object Storage is secure?

  • A. Use a Service Gateway
  • B. Use a NAT Gateway
  • C. Use a VPN Gateway
  • D. Use a Local Peering Gateway

Answer: A

Explanation:
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.
