1Z0-1127-25 Deploying and Managing Generative AI on OCI Practice Question
An enterprise with strict data residency requirements wants to use OCI Generative AI. They must ensure that no training data or inference data leaves a specific OCI region. Which configuration option should they choose?
⚠ Common exam trap
A common mix-up: candidates confuse network-level controls (like service gateways or private endpoints) with data residency enforcement, but only a dedicated, region-locked compute cluster guarantees that no data leaves the specified region.
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
✓
Use a dedicated AI cluster in the desired region and disable cross-region access.
A dedicated AI cluster in the desired region, with cross-region access disabled, ensures that all compute, training data, and inference data remain physically within that OCI region. This satisfies strict data residency requirements because the cluster is isolated from other regions at the network and infrastructure level, preventing any data egress.
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 a dedicated AI cluster in the desired region and disable cross-region access.
Why this is correct
Dedicated clusters are region-specific and can be restricted to prevent cross-region data flow.
- ✗
Configure a service gateway with a private endpoint.
Why it's wrong here
Service gateways provide private connectivity but do not enforce data residency boundaries.
- ✗
Implement a policy restricting data transfer via OCI Identity and Access Management.
Why it's wrong here
IAM policies control access but cannot prevent data from being moved by authorized users or services.
- ✗
Use OCI Data Transfer Service to keep data within the region.
Why it's wrong here
Data Transfer Service is for offline data transfer, not runtime data residency.
