The correct answer is that OCI Audit only records control-plane operations, not data-plane operations like inference. This is because the OCI Audit service is designed to capture management activities—such as creating, updating, or deleting Generative AI resources—but it does not log data-plane API calls that actually run models or generate text. When a security team enables Audit logs and sees no GenAI API calls, the most likely reason is that inference requests are data-plane operations hitting the service endpoint, not the control-plane API. On the Oracle Cloud Infrastructure Generative AI Professional 1Z0-1127 exam, this question tests your understanding of the OCI shared responsibility model and the distinction between control-plane and data-plane logging. A common trap is assuming Audit covers all API calls, when in fact it only covers resource management. To remember: think of Audit as the “manager’s log” (control-plane) and inference as the “worker’s log” (data-plane)—you need separate tools like API Gateway or custom logging for the latter.
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 security team requires that all OCI GenAI API calls be logged and audited. Despite enabling Audit logs in OCI, they do not see GenAI API calls. What is the most likely reason?

Correct answer & explanation
✓
OCI Audit currently only records control-plane operations; data-plane operations like inference are not logged.
C is correct because OCI Audit service is designed to log control-plane operations (e.g., creating, updating, or deleting resources) but does not log data-plane operations such as inference API calls to the Generative AI service. The GenAI inference calls (e.g., generating text) are data-plane operations that occur on the service endpoint, not on the OCI control-plane API, so they are not captured by Audit logs. To log data-plane operations, you would need to use a different mechanism, such as OCI Vault for key usage or custom logging via API Gateway.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The audit log retention policy is too short and logs were overwritten.
Why it's wrong here
Retention policy affects duration, not whether calls are logged at all.
✗
The user is not a tenancy administrator.
Why it's wrong here
Admin rights affect viewing logs, not logging of calls.
✓
OCI Audit currently only records control-plane operations; data-plane operations like inference are not logged.
Why this is correct
Data-plane calls (e.g., model inference) are not captured by Audit; use Service Connector Hub for logging.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The API calls are made by an OCI function, which is not logged.
Why it's wrong here
All API calls are logged regardless of caller if they are management-plane.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume enabling Audit logs captures all API activity, but OCI Audit explicitly excludes data-plane operations, which is a common misconception tested in the 1Z0-1127 exam.
Detailed technical explanation
How to think about this question
OCI Audit uses the OCI Audit API to capture REST API calls to the control-plane endpoints (e.g., /20160918/*), while data-plane endpoints (e.g., /20231130/actions/generateText) are not instrumented for Audit. This separation is common in cloud services to reduce log volume and cost, as data-plane calls can be extremely frequent. In practice, if you need to audit GenAI inference usage, you must implement application-level logging (e.g., in your client code) or use a proxy like OCI API Gateway with logging enabled.

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.
