OCI Enterprise AI Professional 2026: 360 Practice Questions

This course contains the use of artificial intelligence.

Moving from a working chat prototype to an OCI agent requires several distinct decisions: which model and serving mode fit the workload, who executes tools, how knowledge and memory remain current, and how a containerized runtime is governed. These 360 original practice questions help you distinguish those boundaries for the OCI Enterprise AI Professional 2026 exam, 1Z0-1158-26.

The course follows the six scored areas in the current exam outline: LLM concepts, agentic AI, Enterprise AI models, agent development, hosted agents, and governance and optimization. It includes conceptual questions, request and trace interpretation, configuration checks, recovery decisions and calculations with explicitly supplied hypothetical rates.

Your six tests

• Diagnostic and LLM/agent foundations: 60 questions.
• Model selection, customization and dedicated serving: 75 questions.
• Responses, tools, grounding and memory: 70 questions.
• Hosted agents, governance and operations: 55 questions.
• Timed Mock 1: 50 questions in 90 minutes.
• Timed Mock 2: 50 questions in 90 minutes.

Every question includes the correct answer, feedback for each option, an explanation and a study topic. Practice scenarios distinguish function execution from model requests, uploads from searchable vector-store content, memory identity from access policy, inbound networking from egress, and detection from enforcement.

How to use the tests

1. Start with the diagnostic, then work through the focused tests.
2. For each missed question, identify the failed condition and review the suggested topic in Oracle's learning materials.
3. Attempt the mocks without reference materials, then explain why each alternative fails under the stated conditions.

The two mocks match the published 50-question, 90-minute format. Their integer domain allocations average to the published 10/20/20/25/15/10% weights; each individual mock approximates fractional domain counts. The 80% course threshold is an author learning target, not an Oracle score conversion or pass prediction. Oracle publishes a 68% passing score for the exam.

This is an independent practice resource. It is not affiliated with or endorsed by Oracle and contains no claimed live exam questions. It provides practice assessments, not video lessons, a cloud lab or an exam voucher. Use it alongside official study materials and practical experience. AI assisted the question and cover creation; the course includes no claim of guaranteed exam success.
