1Z0-1127-25 Using OCI Generative AI Service Practice Question
A healthcare company must use OCI Generative AI for medical report generation. They need to ensure PHI is not sent to third-party models. Which approach best ensures data stays within OCI?

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
✓
Use OCI Gen AI service with fine-tuned model on a dedicated AI cluster
Using OCI Gen AI service with a fine-tuned model on a dedicated AI cluster ensures that all data (including PHI) remains within OCI's infrastructure, as the dedicated cluster is isolated and no data is sent to third-party models. Fine-tuning also provides the accuracy needed for medical report generation. Option B uses a multi-tenant environment, which may have data isolation concerns but still within OCI; however, it does not involve fine-tuning, so it is less optimal for the medical domain. Option C uses a dedicated cluster but with a base model, which means no fine-tuning on medical data, so it may not provide the required accuracy, though data stays within OCI. Option D sends data to a third-party LLM, violating PHI requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use OCI Gen AI service with fine-tuned model on a dedicated AI cluster
Why this is correct
Correct. A fine-tuned model on a dedicated AI cluster keeps all data within OCI and provides domain-specific accuracy.
- ✗
Use OCI Gen AI service with base model in a multi-tenant environment
Why it's wrong here
Incorrect. While data stays within OCI, the multi-tenant environment may have data isolation concerns, and lack of fine-tuning reduces accuracy for medical reports.
- ✗
Use OCI Gen AI service with base model in a dedicated AI cluster
Why it's wrong here
Incorrect. A dedicated cluster ensures data stays within OCI, but using a base model without fine-tuning does not provide the required medical domain accuracy.
- ✗
Use a third-party LLM via API Gateway
Why it's wrong here
Incorrect. Using a third-party LLM via API Gateway sends PHI outside OCI, violating data residency requirements.
