About the OCI Enterprise AI Professional Exam
Build, deploy, secure, and operate enterprise AI solutions on OCI - from model selection and customization to Responses API agents, hosted applications, guardrails, and cost control.
This practice bank contains 250 original questions for the Oracle Cloud Infrastructure Enterprise AI Professional certification, exam 1Z0-1158-26. The exam tests the full enterprise-AI lifecycle on OCI: applying LLM and agentic concepts, configuring offered or imported models, building agents with OCI’s OpenAI-compatible Responses API and managed tools, deploying custom agent code as hosted applications, and governing the result with IAM, private networking, guardrails, observability, and cost controls.
Who Should Take This Exam?
The certification is aimed at AI engineers, agent developers, machine-learning engineers, platform engineers, cloud architects, security engineers, and technical leads who build production AI applications on OCI.
You should be comfortable choosing between prompting, retrieval, imported models, and fine-tuning; working with agent tools and memory; and reasoning about production deployment, security, reliability, and cost.
Prerequisites: None required. Hands-on OCI Generative AI and agent-development experience is strongly recommended.
Typical study time: 5-8 weeks of focused study, depending on your OCI and agentic-AI experience.

Exam Domains & Weights
Oracle lists a 0% orientation objective, Describing OCI Enterprise AI Capabilities, followed by six scored domains. The practice-bank counts below follow the official scored weights.
| Domain | Weight | Practice Qs |
|---|---|---|
| Applying Large Language Model Concepts | 10% | 25 |
| Applying Agentic AI Concepts | 20% | 50 |
| Configuring OCI Enterprise AI Models | 20% | 50 |
| Building OCI Enterprise AI Agents | 25% | 63 |
| Building and Deploying Hosted Agents | 15% | 37 |
| Governing and Optimizing OCI Enterprise AI | 10% | 25 |
| Total | 100% | 250 |
Study tip: Start with the two implementation-heavy areas: Building OCI Enterprise AI Agents and Configuring OCI Enterprise AI Models. Keep the OCI layers straight - model serving and fine-tuning, Responses API agents and tools, hosted container applications, and database-native agentic AI are related but not interchangeable.
Practice Exam - 250 Questions
Prepare with a 250-question practice exam covering all six scored domains. Every question uses a realistic enterprise-AI scenario and includes a detailed explanation, per-option rationale, hint, exam tip, and real-world context.
What you get:
- Exam simulation mode with timer
- Spaced repetition for weak areas
- Detailed explanations for every question
- Progress tracking across domains
- 20 free questions - no account needed
What to Study First
- Separate the model choices - on-demand versus dedicated, offered versus imported, prompting versus retrieval versus fine-tuning, and fine-tuning versus hosting clusters.
- Learn the agent API layers - Responses generates work, Conversations carries state, Projects isolate resources and memory, and Files/Vector Stores ground retrieval.
- Map each tool to its job - File Search, Code Interpreter, Function Calling, and MCP Calling solve different agent requirements.
- Understand hosted applications - application settings, container-image deployments, active versions, replicas, autoscaling, managed storage, networking, authentication, and endpoints.
- Treat governance as an architecture decision - least privilege, private access, retention, guardrails, observability, and cost controls belong in the design from the start.
- Keep the database exam separate - VECTOR, DBMS_VECTOR_CHAIN, Select AI, and the Autonomous Database MCP Server belong to 1Z0-1159-26, not this exam.
Oracle AI Certification Path
A practical sequence is OCI AI Foundations Associate for the broad concepts, then OCI Enterprise AI Professional for the cloud platform and agent lifecycle. Add Agentic AI for Oracle AI Database Professional if your work moves agent reasoning, retrieval, and tool access into Oracle AI Database.

Frequently Asked Questions
1. What does OCI Enterprise AI Professional 1Z0-1158-26 cover?
The exam covers six scored domains: large language model concepts; agentic AI concepts; configuring OCI Enterprise AI Models; building OCI Enterprise AI Agents with the Responses API, tools, Projects, memory, Files, and Vector Stores; building and deploying hosted agents; and governing and optimizing enterprise AI with IAM, private networking, guardrails, observability, and cost controls.
2. Is 1Z0-1158-26 a lab exam?
No. Oracle's live MyLearn metadata lists a 50-question, 90-minute Multiple Choice exam with a 68% passing score. The official learning path presents it as an online certification exam and does not list a hands-on performance lab.
3. Do I need another Oracle certification first?
No formal prerequisite is listed. Oracle recommends practical experience with OCI Generative AI, large language models, agentic AI, model customization, the OCI Responses API, and hosted agent deployments.
4. How is this different from the Agentic AI for Oracle AI Database Professional exam?
1Z0-1158-26 is the OCI platform-level exam: Enterprise AI Models, Responses API agents and tools, Projects and memory, hosted applications, deployments, governance, and cost. The 1Z0-1159-26 database exam focuses on Oracle AI Database features such as VECTOR, DBMS_VECTOR_CHAIN, Select AI, the Autonomous Database MCP Server, and Private Agent Factory.
