This section evaluates your understanding of how generative AI models function. Topics include:

• What large language models are and how they generate text

• Transformer architecture and attention mechanisms

• Prompt engineering techniques

• Model fine tuning concepts

• Differences between chat, embedding, and code models

You must understand how inputs are processed and how outputs are generated in enterprise AI applications.

2. OCI Generative AI Services

This is the most heavily weighted domain in the exam. It focuses on hands on usage of Oracle’s generative AI services, including:

• Working with pre trained foundational models

• Using OCI Generative AI endpoints

• Managing inference and embeddings

• Fine tuning models using dedicated AI infrastructure

• Implementing security, access control, and governance

This section ensures that candidates can confidently deploy generative AI workloads in OCI while following best practices.

3. Retrieval Augmented Generation (RAG) on OCI

Retrieval Augmented Generation is a critical enterprise AI pattern, and Oracle places strong highlighting on it. Topics include:

• Understanding how RAG improves response accuracy

• Vector embeddings and similarity search

• Document sectioning strategies

• Integrating generative AI with enterprise data

• Building contextual responses using retrieved information

Candidates must understand how to combine external data sources with generative models to produce reliable, business ready outputs.

4. OCI Generative AI Agents

This domain focuses on building intelligent AI agents that can interact with users and systems. You are expected to understand:

• AI agent architecture and lifecycle

• Creating and managing knowledge bases

• Deploying conversational AI agents

• Using agents for automated workflows

• Monitoring and optimizing agent performance

This section validates your ability to operationalize generative AI beyond simple text generation.
