- A
An embedding model
Why wrong: Embedding is used internally but not a component you configure separately for Agents.
- B
A knowledge base
Required to store indexed documents.
- C
A dedicated AI cluster
Why wrong: Not required for Agents; Agents use shared infrastructure.
- D
A data source (e.g., OCI Object Storage)
Required to provide documents for the knowledge base.
- E
A fine-tuned model
Why wrong: Not required; Agents use foundation models.

1Z0-1127 OCI Generative AI Service Practice Question
This 1Z0-1127 practice question tests your understanding of oci generative ai service. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to build a RAG application using OCI Generative AI Agents. Which TWO components are required to set up the agent?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A knowledge base
Option B is correct because a knowledge base is the core repository that stores the indexed content used by OCI Generative AI Agents to retrieve relevant information for answering queries. Without a knowledge base, the agent has no source of domain-specific data to ground its responses, making it a mandatory component.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that you need to separately provision an embedding model or a dedicated AI cluster, when in fact OCI Generative AI Agents abstract these components away as part of the managed service, requiring only a data source and a knowledge base.
Detailed technical explanation
How to think about this question
Under the hood, OCI Generative AI Agents use a retrieval-augmented generation (RAG) pipeline where the knowledge base is built by chunking documents from a data source (e.g., OCI Object Storage), generating embeddings via an internal model, and storing them in a vector index. When a query is received, the agent retrieves the most relevant chunks using cosine similarity search and passes them as context to the generative model, ensuring responses are grounded in the provided data. A real-world scenario is a customer support agent that ingests PDF manuals from Object Storage; without the knowledge base and data source, the agent would have no content to retrieve and would generate generic or hallucinated answers.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-1127 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
