Microsoft Azure Administrator Associate AZ-104 Practice Question
You have a web application that runs in Azure App Service. You open the Scale-out (App Service plan) blade and configure automatic scaling for the underlying App Service plan. Which capability can this configuration provide without deploying additional Azure resources? (Select one answer.)
Distribute requests across multiple regions by using Azure Traffic Manager.
Automatically replicate the app to additional Azure regions during high load.
Increase or decrease the number of instances within the same Azure region based on HTTP request load.
Automatically change the App Service plan's pricing tier when CPU usage spikes.
Automatic or autoscale settings on an App Service plan can only add or remove worker instances that run in the same region as the plan. This is horizontal scaling inside the existing plan.
Correct-automatic scaling can increase or decrease the number of instances within the current region when load changes. B & D. Incorrect-a single App Service plan cannot span or replicate to other Azure regions; global distribution requires separate plans in each region plus a global load balancer such as Azure Front Door or Traffic Manager.
Incorrect-changing pricing tiers (vertical scale-up) is a manual action and is not triggered by autoscale rules.
