You have 10 Azure App Service instances hosting the same web app, each deployed in a different Azure region. You need to configure Azure Traffic Manager so that clients are routed to the app instance with the lowest network latency. Which Traffic Manager routing method should you choose?

The performance routing method in Azure Traffic Manager routes client requests to the endpoint that has the lowest network latency from the client's perspective. This is ideal for scenarios where you want to provide the fastest possible response time to users by directing them to the closest available service instance. Geographic routing directs users to specific endpoints based on their geographic location, which is not about latency. Weighted routing distributes traffic across endpoints based on assigned weights, useful for even distribution or A/B testing, not lowest latency. Priority routing directs all traffic to a primary endpoint and only fails over to secondary endpoints if the primary is unavailable, which is for disaster recovery, not performance optimization.
