The OCI 2025 Developer Professional certification, which is known as the 1Z0-1084-25 exam, represents a critical point of reference among cloud developers who want to prove their skills in building and deploying cloud-native applications to Oracle Cloud Infrastructure (OCI). By maintaining the latest updates of OCI’s offerings, the revamped Developer Professional Exam ensures certified developers are well situate in the fast evolving cloud environment. Here, I’ll speak about the latest changes made to the 1Z0-1084-25 exam, analyze its format, and provide you with useful information on your preparation.
What’s New in the 1Z0-1084-25 Exam?
Oracle updates its certification exams regularly to align with new features and industry trends. The OCI 2025 Developer Professional exam introduces several changes compared to its 2024 predecessor (1Z0-1084-24). Here’s what’s fresh:
Expanded Focus on Cloud-Native Technologies
The 1Z0-1084-25 exam dives deeper into cloud-native development principles, emphasizing microservices, containerization, and serverless architectures. Expect more questions on how to design scalable applications using OCI’s Container Engine for Kubernetes (OKE) and Oracle Functions. The exam tests your ability to integrate these technologies into real-world scenarios, reflecting the growing adoption of cloud-native practices.
Enhanced Security and Monitoring Coverage
Security remains a priority in the Developer Professional Exam. The 2025 version includes updated content on OCI Vault for managing encryption keys and sensitive data. You’ll also face questions on securing APIs with OCI API Gateway and implementing rate-limiting to prevent DDoS attacks. Additionally, monitoring and troubleshooting have a stronger presence, with a focus on OCI Monitoring and Logging services to track application performance.
New Topics on DevOps and CI/CD
The exam now places greater emphasis on DevOps practices, including continuous integration and continuous deployment (CI/CD) workflows. You’ll need to understand how to automate deployments using OCI DevOps services and integrate them with OCI Registry for container image management. These additions ensure you’re equipped to streamline development pipelines in OCI environments.
Updated OCI Services and Features
Oracle has introduced new tools and enhancements in 2025, and the 1Z0-1084-25 reflects these updates. For example, you’ll encounter questions on the latest capabilities of OCI Registry for managing Docker images and improved integrations with other OCI services. Staying current with these updates is crucial for success.
Exam Structure and Key Details
The OCI 2025 Developer Professional exam tests your knowledge across several domains. According to Oracle’s official syllabus, the main topics include:
Cloud-Native Fundamentals: Understand core principles and pillars of cloud-native development.
Containerization: Work with Docker, OCI Registry, and OKE for containerized applications.
Serverless Development: Build and deploy applications using Oracle Functions.
Security: Implement secure practices with OCI Vault and API Gateway.
Monitoring and Troubleshooting: Use OCI Monitoring and Logging to manage applications.
DevOps and CI/CD: Automate workflows with OCI DevOps and Registry.
The exam consists of multiple-choice and scenario-based questions, typically around 55–60 in total, with a duration of 90 minutes. The passing score is around 65%, though this may vary. Oracle recommends hands-on experience with OCI services to tackle the practical, real-world scenarios in the 1Z0-1084-25.
