OCI Developer Professional study guide
OCI Developer Professional · Work through your exam, one topic at a time.
The Oracle Cloud Infrastructure Developer Professional credential is Oracle's professional-level certification for developers who build, deploy, and operate applications on Oracle Cloud Infrastructure. It is aimed at engineers who already write code against cloud APIs and want independent validation of their OCI development skills for employers, clients, or internal promotion. The exam is identified by code 1Z0-1084, and Oracle University lists it under that exam code on its certification page. Because the Oracle University page was unavailable when this reference was compiled, this guide does not state the question count, time limit, passing score, exam fee, delivery format, retake rules, or validity period; treat any figure you see elsewhere as unverified until you confirm it on Oracle's own site. In practical terms, preparation should combine hands-on work in an OCI tenancy with the official exam objectives. Expect to practise provisioning and connecting to OCI services from application code, managing credentials and configuration, automating deployments, and troubleshooting failures. Topics on this exam: Oracle Cloud Infrastructure Developer. The OCI Developer Professional study guide has 1 section and about 406 words.
01Oracle Cloud Infrastructure Developer
This domain tests how you build, deploy, secure, and operate applications on OCI, not how well you memorize console screens. Expect serverless functions, API Gateway, containers and OKE, DevOps pipelines, Streaming, and IAM resource principals. OCI Functions packages code as a Docker image stored in OCIR. Invoke it through API Gateway, OCI Events, or an SDK; use application configuration for environment values and resource principals for OCI API calls.

- Practice questionsA developer wants a function in OCI Functions to read secrets at runtime without embedding credentials in the image.
- FlashcardsInstance principal authentication. A keyless OCI authentication method where a compute instance proves its identity to the metadata service and exchanges a signed request for a short-lived token, authorized through a dynamic group and IAM policy.
- Cheat sheetOCI CLI authentication precedence: command-line flags override the profile selected by --profile, which overrides the OCI CLI PROFILE environment variable, which overrides the DEFAULT profile in ~/.oci/config; OCI CLI CONFIG FILE relocates the config file itself.
- Key termsTenancy. The top-level Oracle Cloud Infrastructure account that owns all resources, users, and billing.
- Study planMap the OCI Developer Professional exam domains to your existing skills and list the three weakest areas.
- Common mistakesCandidates who come from single-region cloud backgrounds memorize service names without memorizing the compartment-plus-region resource hierarchy, so they mis-answer questions about where a resource lives and how IAM policies scope to it.
