AI-102 Implement generative AI solutions Practice Question
Your Azure OpenAI application experiences high latency during peak hours. You have already scaled up the deployment to the maximum PTUs. What is the most effective next step to reduce latency?
⚠ Common exam trap
A common mix-up: candidates assume 'global deployment' (Option B) provides automatic load distribution, but in reality it still uses a single PTU pool and does not distribute load across regions; the correct approach is to explicitly create multiple regional deployments and route traffic with a traffic manager.

Correct answer & explanation
✓
Create multiple deployments across different regions and use Azure Traffic Manager to distribute requests
When PTU deployment is already maxed out, the bottleneck is the capacity of a single regional deployment. Distributing requests across multiple regional deployments via Azure Traffic Manager (using performance or geographic routing) spreads the load, reducing per-deployment contention and lowering latency. This approach leverages regional redundancy and global load balancing without requiring a model change or sacrificing quality.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create multiple deployments across different regions and use Azure Traffic Manager to distribute requests
Why this is correct
Geographic load balancing spreads load and reduces latency.
- ✗
Use Azure OpenAI's global deployment with the same PTU
Why it's wrong here
Global deployment doesn't increase capacity beyond PTU limit.
- ✗
Switch from GPT-4 to GPT-3.5-turbo
Why it's wrong here
This may reduce quality and still not address peak load.
- ✗
Increase the token limit per request
Why it's wrong here
Increasing token limit can increase latency per request.
