The Oracle Cloud Infrastructure 2025 DevOps Professional exam (1Z0-1109-25) is designed for cloud engineers and DevOps practitioners who implement and manage infrastructure automation, containerization, and CI/CD pipelines on Oracle Cloud Infrastructure. This certification validates your ability to design and deploy modern DevOps solutions using Oracle Cloud services. This page provides a structured study roadmap, practical exam guidance, and resources to help you prepare efficiently and confidently.
Use this topic map to guide your study for Oracle 1Z0-1109-25 (Oracle Cloud Infrastructure 2025 DevOps Professional) within the Oracle Cloud and Oracle Cloud Infrastructure path.
The 1Z0-1109-25 exam uses multiple question types to assess both conceptual knowledge and practical decision-making in real-world DevOps scenarios.
Questions increase in complexity and emphasize practical application, ensuring you can make informed decisions in production DevOps workflows.
An effective study plan maps each topic to weekly goals, incorporates hands-on practice, and builds confidence through progressive testing. Allocate study time proportionally to topic weight and your current knowledge gaps.

CI/CD configuration and Container Orchestration typically account for the largest portion of exam questions, followed by Infrastructure as Code and Monitoring. However, all six domains are tested, so balanced preparation across all topics is essential. Review the official exam guide and adjust study time based on your current experience level.
Infrastructure as Code (Terraform, Resource Manager) defines your cloud resources, while CI/CD pipelines automate the deployment of both infrastructure changes and application code. On the exam, expect questions that show how IaC templates are versioned in source control, triggered by CI/CD stages, and deployed to multiple environments. Understanding this integration is critical for scenario-based questions.
Hands-on experience significantly improves retention and confidence. Prioritize labs that involve creating a CI/CD pipeline end-to-end, deploying a containerized application to OKE, setting up monitoring and alarms, and using Terraform to provision infrastructure. If you have limited lab access, focus on understanding the concepts deeply through practice questions and scenario walkthroughs.
Frequent errors include confusing Kubernetes resource types, misunderstanding DevSecOps integration points (e.g., where to scan for vulnerabilities in the pipeline), overlooking monitoring best practices for distributed systems, and underestimating the importance of proper RBAC and security group configuration. Review explanations carefully during practice tests to avoid repeating these mistakes on exam day.
In the final week, focus on high-value activities: review all scenario-based questions and your weak-point topics, do one full-length timed practice test, and study explanations for any questions you missed. Avoid cramming new material; instead, reinforce understanding of core concepts and build confidence through targeted review. Get adequate sleep the night before the exam.
An operations team is exploring the use of OCI Container Instances to run their container workloads without managing servers.
Which of the following statements is false regarding the use of Container Instances?
OCI Container Instances are a serverless compute service that allows you to run containerized workloads without managing the underlying infrastructure. Oracle Cloud Infrastructure (OCI) manages provisioning, patching, and all the ongoing server management tasks, providing a fully managed environment.
Which two are prerequisites for creating a secret in Oracle Cloud Infrastructure Vault service? (Choose two.)
You need the required permissions (such as policies allowing secret management) to create and manage secrets in Oracle Cloud Infrastructure (OCI) Vault service. These permissions are essential for performing operations such as creating, reading, and managing secrets.
Vault managed key is required to encrypt the secret before it is stored in the OCI Vault. The managed key acts as the encryption key for securing the secret, ensuring its confidentiality.
What is the correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) Cluster to a newer version of Kubernetes?
The correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) cluster involves first upgrading the Kubernetes control plane, followed by upgrading the node pools. The control plane must be upgraded first to ensure compatibility with newer versions of Kubernetes, as node pools rely on the control plane for orchestration and management.
After upgrading the control plane, each node pool is upgraded to match the new Kubernetes version. This phased approach ensures the cluster remains in a stable state during the upgrade.
As a DevOps Engineer, you are tasked with explaining the key concepts of Terraform to a new team member. You want to ensure they understand the fundamental concepts of Terraform.
Which of the following best describes the purpose of Terraform variables?
Terraform variables are used to define input values for Terraform configurations. They allow users to customize infrastructure deployments by providing different values without modifying the configuration files themselves. Variables help in creating reusable infrastructure code, making it easy to maintain and adjust the infrastructure setup according to different environments or needs.
As an engineer building and deploying applications using an OCI DevOps project, which two capabilities can help ensure the security and reliability of the code in the build and deployment pipelines? (Choose two.)
Application Dependency Management (ADM) is a tool used to identify security weaknesses in software applications by analyzing their dependencies. Dependencies can often introduce vulnerabilities, and managing them properly is a critical part of ensuring application security.
Third-party tools like Sonatype and SonarQube can be used to analyze code for security defects or bugs in code quality. These tools help in identifying vulnerabilities, code smells, and other issues, which can improve the overall security and reliability of the code during the build process.
