Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You develop and deploy an Azure App Service API app to a Windows-hosted deployment slot named Development. You create additional deployment slots named Testing and Production. You enable auto swap on the Production deployment slot. You need to ensure that scripts run and resources are available before a swap operation occurs. Solution: Update the web.config file to include the applicationInitialization configuration element.

Explanation

Specify custom warm-up. Some apps might require custom warm-up actions before the swap. The applicationInitialization configuration element in web.config lets you specify custom initialization actions. The swap operation waits for this custom warm-up to finish before swapping with the target slot. Here's a sample web.config fragment. <system.webServer> <applicationInitialization> <add initializationPage="/" hostName="[app hostname]" /> <add initializationPage="/Home/About" hostName="[app hostname]" /> </applicationInitialization> </system.webServer> https://docs.microsoft.com/en-us/azure/app-service/deploy-staging-slots#troubleshoot-swaps
