1Z0-1127-25 Deploying and Managing Generative AI on OCI Practice Question
A financial institution needs to deploy a fine-tuned model on OCI with strict data residency requirements. They must ensure that data used for inference never leaves a specific OCI region. The model is stored in Object Storage in the same region. What additional configuration is needed?
⚠ Common exam trap
Many candidates confuse data residency with data security, incorrectly assuming that a VPN (Option C) or cross-region replication (Option D) can enforce regional confinement, when in fact they either route data outside the region or actively replicate it across regions.

Correct answer & explanation
✓
Configure the dedicated AI cluster to use a private endpoint and restrict access to the region
Configuring the dedicated AI cluster to use a private endpoint ensures that inference traffic stays within the OCI region and never traverses the public internet. This satisfies the strict data residency requirement by keeping all data and model inference within the designated region, while the model stored in Object Storage in the same region is accessed via the private endpoint without leaving the region.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure the dedicated AI cluster to use a private endpoint and restrict access to the region
Why this is correct
Private endpoints keep all traffic within the OCI network and the same region.
- ✗
Use OCI Data Transfer service to move data
Why it's wrong here
Data Transfer is for offline bulk data import/export, not for inference-time residency.
- ✗
Set up a VPN connection to on-premises
Why it's wrong here
VPN connects to on-premises, not relevant for regional data residency.
- ✗
Enable cross-region replication on the bucket
Why it's wrong here
Cross-region replication would copy data to another region, violating data residency.
