1Z0-1127-25 Practice Question: Building LLM Applications with RAG and Vector Search
A healthcare organization plans to deploy a RAG application on OCI that handles sensitive patient data. They require that all LLM inference and embedding processing happen within a controlled environment to avoid data leakage to public endpoints. Which OCI feature should they use?
⚠ Common exam trap
The common trap in Oracle exams is that candidates may confuse data protection features like OCI Vault (encryption) or OCI Data Masking with the need for a private compute environment, failing to recognize that OCI Dedicated AI Cluster is the only option that physically isolates the AI processing pipeline from public networks.
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 Dedicated AI Cluster
OCI Dedicated AI Cluster provides a fully isolated, single-tenant infrastructure for running AI workloads, including LLM inference and embedding processing. This ensures all data processing occurs within a controlled environment without traversing public endpoints, meeting the healthcare organization's requirement to prevent data leakage of sensitive patient data.
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 Data Labeling
Why it's wrong here
Used for creating labeled datasets.
- ✗
OCI Vault
Why it's wrong here
Manages encryption keys, not inference environment.
- ✗
OCI Data Masking
Why it's wrong here
Protects sensitive data in databases, not for inference isolation.
- ✓
OCI Dedicated AI Cluster
Why this is correct
Dedicated AI Cluster provides isolated compute for AI workloads.
