1Z0-1127-25 Using OCI Generative AI Service Practice Question
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?
⚠ Common exam trap
Many exam-takers 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.
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.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OCI Vault for encryption and OCI Audit for logging.
Why it's wrong here
Vault handles encryption keys, and Audit logs API calls but not model inference details.
- ✓
OCI Identity and Access Management (IAM) policies and OCI Logging.
Why this is correct
IAM controls access, Logging records inference requests for audit.
- ✗
OCI Data Safe and OCI Monitoring.
Why it's wrong here
Data Safe is for database security, Monitoring is for metrics, not detailed logs.
- ✗
OCI API Gateway with authentication and OCI Audit.
Why it's wrong here
API Gateway can authenticate but Audit does not log inference content.
