AI-102 Plan and manage an Azure AI solution Practice Question
You are planning to deploy an Azure AI solution that uses an Azure AI Services multi-service resource. The solution must be deployed across multiple Azure regions to provide high availability. You need to ensure that the solution can fail over automatically if one region becomes unavailable. What should you do?
⚠ Common exam trap
The trap here is assuming that data replication or DNS-based load balancing alone provides automatic failover, when health-checked routing such as Traffic Manager priority routing is needed for automatic region failover.
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
✓
Deploy the Azure AI Services resource in two regions and configure a Traffic Manager profile with priority routing.
Deploying the resource in two regions and using Traffic Manager with priority routing ensures that traffic is directed to the primary region and automatically redirected to the secondary if the primary fails. This provides the required high availability and automatic failover. Other options either replicate data without failover or rely on DNS without health checks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy the Azure AI Services resource in one region and configure a custom domain with multiple CNAME records.
Why it's wrong here
Multiple CNAME records can provide round-robin DNS but do not offer automatic failover or health-based routing. DNS changes are slow to propagate and clients may still be directed to the failed region. This option does not meet the automatic failover requirement.
- ✓
Deploy the Azure AI Services resource in two regions and configure a Traffic Manager profile with priority routing.
Why this is correct
Traffic Manager with priority routing directs all traffic to the primary region and automatically fails over to the secondary region if the primary becomes unavailable. This provides high availability and automatic failover for the Azure AI Services resource across regions, meeting the requirement.
- ✗
Deploy the Azure AI Services resource in two regions and use Azure Front Door with session affinity enabled.
Why it's wrong here
Azure Front Door with session affinity can distribute traffic but does not automatically fail over based on region health unless configured with health probes and priority. Session affinity alone does not ensure failover; it keeps a user on the same backend, which could be the failed region. This option is not the most direct solution.
- ✗
Deploy the Azure AI Services resource in one region and enable geo-redundant storage for the resource.
Why it's wrong here
Geo-redundant storage replicates data but does not provide failover for the Azure AI Services endpoint. The service itself remains in a single region, so if that region fails, the service is unavailable. This option does not achieve cross-region high availability.
