Three full-length practice tests for the Oracle Cloud Infrastructure Developer Professional (1Z0-1084-26) certification exam - 50 questions per test, 90 minutes, 68% to pass, unlimited retakes.
Every question is grounded in Oracle's official exam objectives and product documentation - written fresh for this course, not recycled from public dumps.
What you'll be tested on
- OCI SDKs, CLI, and REST API authentication and usage
- Container orchestration with OKE and OCI Container Registry
- Serverless development with OCI Functions and API Gateway
- CI/CD pipelines with DevOps service, Resource Manager, and Terraform
- Event-driven architectures using Streaming, Notifications, and Events service
Where candidates lose points
Most candidates who fail this exam aren't tripped up by any single service, but by the seams between them - for example wiring Functions authentication through resource principals instead of static API keys, or getting a Vault secret injected correctly into an OKE deployment. Scenario questions tend to chain two or three services into one flow, such as API Gateway routing to a function that reads a Vault secret and writes to Streaming, so shallow single-service knowledge isn't enough. Container image lifecycle and registry permissions in OCIR are also a common weak spot for developers coming from a non-OCI CI/CD background.
Sample question
A development team needs a serverless function deployed on OCI to authenticate against another OCI service without embedding long-lived credentials in the function's code. Which authentication approach should they use?
- A. Store an API signing key pair as function configuration variables
- B. Use resource principal authentication so the function obtains a short-lived token automatically
- C. Hard-code the tenancy OCID and user OCID in the function's environment variables
- D. Configure a database connection string with embedded credentials
Full explanations and 149 more questions like this are in the practice tests.
How long to prepare
If you've already deployed applications on OCI using the CLI or SDKs and have touched OKE and Functions hands-on, 3-4 weeks of focused review covering API Gateway, DevOps pipelines, and event-driven services should be enough to sit the exam comfortably. Coming in without that hands-on OCI experience, plan for closer to 6-8 weeks.
