- A
OCI Vault for encryption and OCI Audit for logging.
Why wrong: Vault handles encryption keys, and Audit logs API calls but not model inference details.
- B
OCI Identity and Access Management (IAM) policies and OCI Logging.
IAM controls access, Logging records inference requests for audit.
- C
OCI Data Safe and OCI Monitoring.
Why wrong: Data Safe is for database security, Monitoring is for metrics, not detailed logs.
- D
OCI API Gateway with authentication and OCI Audit.
Why wrong: API Gateway can authenticate but Audit does not log inference content.

1Z0-1127 Using OCI Generative AI Service Practice Question
This 1Z0-1127 practice question tests your understanding of using 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 uses OCI Generative AI to generate legal document summaries. They have a custom model deployed on a dedicated AI cluster. They want to ensure that the model is not used by unauthorized users. They also need to log all inference requests for auditing. Which combination of OCI services should they use?
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
✓
OCI Identity and Access Management (IAM) policies and OCI Logging.
Option B is correct because OCI IAM policies are the primary mechanism for controlling access to OCI resources, including custom models on dedicated AI clusters, by defining which users or groups can invoke the model. OCI Logging captures detailed logs of all inference requests, including metadata such as timestamps, source IPs, and request payloads, which satisfies the auditing requirement. Together, they provide both authorization enforcement and audit trail without additional services.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
OCI Data Safe and OCI Monitoring.
Why it's wrong here

- ✗
OCI API Gateway with authentication and OCI Audit.
Why it's wrong here
API Gateway can authenticate but Audit does not log inference content.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse OCI Audit (which logs only management-plane operations) with OCI Logging (which logs data-plane operations like inference requests), leading them to pick Option A or D, while also overlooking that IAM policies are the native access control mechanism for Generative AI models on dedicated clusters.
Detailed technical explanation
How to think about this question
OCI IAM policies for Generative AI use resource-type `generative-ai-model` and verbs like `infer` to grant or deny inference access at the model level, which can be scoped to compartments or specific model OCIDs. OCI Logging for Generative AI captures structured log entries with fields such as `requestId`, `modelId`, `userId`, `inferenceTime`, and `responseStatus`, which can be exported to Object Storage or streamed to a SIEM for compliance. In a real-world scenario, a company might combine IAM with resource principal authentication for workloads running in OCI Functions to avoid storing user credentials.
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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
