1Z0-1127-25 Deploying and Managing Generative AI on OCI Practice Question
A multinational corporation uses OCI Generative AI to power a customer support chatbot. The chatbot uses a fine-tuned model deployed on a dedicated AI cluster in the us-ashburn-1 region. The application is used globally, and users in Europe are experiencing high latency (over 2 seconds) compared to users in North America (under 500 ms). The company has a requirement to keep all data within the US due to compliance, so they cannot deploy in Europe. The latency is not due to network bandwidth but due to the inference time. The monitoring shows that the cluster is at 80% utilization during peak hours. The team wants to reduce the latency for European users without violating data residency. What is the best course of action?
⚠ Common exam trap
A common mix-up: candidates confuse latency caused by inference time with latency caused by network distance or cluster load, leading them to choose scaling or caching solutions that do not address the fundamental computational bottleneck.

Correct answer & explanation
✓
Optimize the model using techniques like quantization or pruning to reduce inference time.
The latency issue is explicitly due to inference time, not network bandwidth or cluster utilization. Model optimization techniques like quantization (reducing precision of weights from FP32 to INT8) and pruning (removing redundant neurons) directly reduce the computational cost per inference, thereby lowering the response time without moving data or changing the deployment region. This approach satisfies the data residency constraint while addressing the root cause of high latency for European users.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Optimize the model using techniques like quantization or pruning to reduce inference time.
Why this is correct
Model optimization directly reduces per-request latency without moving data.
- ✗
Implement an edge caching layer in Europe to serve common queries.
Why it's wrong here
Caching helps only with repeated queries, not unique or new requests.
- ✗
Increase the number of nodes in the cluster to distribute the load.
Why it's wrong here
More nodes reduce queue time but do not reduce the inference time per request.
- ✗
Deploy an additional endpoint in a European region and use a global load balancer.
Why it's wrong here
This violates the data residency requirement.
