AI-102 Plan and manage an Azure AI solution Practice Question
You are planning an Azure AI solution that uses Azure OpenAI. You need to ensure that the solution can be deployed to multiple regions for high availability. The solution must automatically route requests to the nearest available region and fail over if a region becomes unavailable. What should you use?
⚠ Common exam trap
The trap here is selecting a regional load balancer like Azure Load Balancer or Application Gateway for a multi-region scenario, or choosing Traffic Manager with priority routing when latency-based routing is required.
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
✓
Azure Front Door with latency-based routing
Azure Front Door is the appropriate service because it provides global HTTP load balancing with latency-based routing and automatic failover. It can route requests to the nearest available Azure OpenAI endpoint across multiple regions and detect unhealthy endpoints to redirect traffic. The other options are either regional load balancers or do not support latency-based global routing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Front Door with latency-based routing
Why this is correct
Azure Front Door is a global HTTP load balancer that supports latency-based routing, which directs requests to the lowest-latency endpoint. It also provides automatic failover if an endpoint becomes unhealthy. This meets the requirements for multi-region deployment, nearest-region routing, and failover for Azure OpenAI.
- ✗
Azure Load Balancer with availability zones
Why it's wrong here
Azure Load Balancer operates at the regional level and distributes traffic across virtual machines within a single region or across availability zones. It cannot route traffic across multiple Azure regions, nor does it provide global latency-based routing. It is not suitable for a multi-region Azure OpenAI deployment that requires global failover.
- ✗
Azure Application Gateway with multi-site listeners
Why it's wrong here
Azure Application Gateway is a regional layer-7 load balancer that can route traffic to multiple backends within a region. It does not provide global routing across regions or automatic failover between regions. While it supports multi-site listeners for host-based routing, it cannot fulfill the requirement for nearest-region routing across multiple Azure regions.
- ✗
Azure Traffic Manager with priority routing
Why it's wrong here
Azure Traffic Manager with priority routing directs all traffic to a primary endpoint and only fails over to a secondary when the primary is unavailable. It does not automatically route to the nearest region based on latency; for that, you would need performance routing. While it can provide failover, the requirement for nearest-region routing is not met by priority routing alone.
