Correct answer & explanation
✓
Vertex AI
Vertex AI is the correct access method because it is the only option that allows fine-tuning of Gemini models within a customer's VPC (Virtual Private Cloud) with full audit logging via Cloud Audit Logs. This ensures proprietary financial data never leaves the secure network boundary, meeting strict compliance and data residency requirements.
