About the OCI-DEVELOPER-PROFESSIONAL Exam
Master the Oracle Cloud Infrastructure (OCI) 2026 Developer Professional exam (1Z0-1084-26) — cloud-native fundamentals and microservices, containerization with Docker, OCI Container Registry (OCIR) and Oracle Kubernetes Engine (OKE), serverless development with Oracle Functions, API Gateway, Streaming, Events and Queue, testing and securing apps with OCI Vault, and monitoring, logging and tracing for cloud-native applications.
The complete practice exam for the Oracle Cloud Infrastructure 2026 Developer Professional certification (exam 1Z0-1084-26, current 2026 version). Covers Cloud Native Fundamentals (cloud-native pillars, 12-factor apps, microservices architecture and design methodology), Cloud Native Applications and Containerization (Docker images and Dockerfiles, OCI Container Registry pull/push, image tags signing and scanning, container orchestration, building and deploying on Oracle Kubernetes Engine with Pods, Deployments, Services, Ingress, ConfigMaps and Secrets, Helm, autoscaling, VCN-native pod networking, persistent volumes, RBAC and workload identity), Serverless Technologies (Oracle Functions and the Fn FDK, API Gateway routes and request/response policies and authorizers, OCI Streaming with Apache Kafka compatibility, OCI Events service rules, OCI Queue asynchronous messaging), Testing and Securing Cloud Native Applications (cloud-native testing strategies, OCI Vault keys and secrets, envelope encryption, least-privilege IAM, dynamic groups and resource principals, image scanning and signing), and Monitoring and Troubleshooting (OCI Monitoring metrics and alarms, Logging and Logging Search, Application Performance Monitoring and distributed tracing) — every question a real-world cloud-native development scenario with full explanations.
Who Should Take This Exam?
The OCI 2026 Developer Professional (1Z0-1084-26) is designed for cloud developers, application developers, and DevOps engineers who build, deploy, and operate cloud-native applications on Oracle Cloud Infrastructure — using containers and Oracle Kubernetes Engine (OKE), serverless Oracle Functions, API Gateway, Streaming, Events and Queue, and OCI Vault. It validates hands-on developer skills, so practical experience with microservices, Docker, Kubernetes, and a programming language is strongly recommended. It builds naturally on the OCI Foundations and Architect Associate certifications.
Prerequisites: None (OCI fundamentals plus hands-on experience with microservices, Docker, Kubernetes/OKE, Oracle Functions, and basic programming recommended)
Typical study time: 8-12 weeks of intensive study
