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 app with a method named statuscheck to run the scripts.
Update the app settings for the app.
Set the WEBSITE_SWAP_WARMUP_PING_PATH and WEBSITE_SWAP_WARMUP_PING_STATUSES with a path to the new method and appropriate response codes.
Does the solution meet the goal?

A. B.A.
These are valid warm-up behavior options, but are not helpful in fixing swap problems.
Instead update the web.config file to include the applicationInitialization configuration element.
Specify custom initialization actions to run the scripts.
Note: 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> Reference: https://docs.microsoft.com/en-us/azure/app-service/deploy-staging-slots#troubleshoot-swaps.
The solution mentioned in the scenario should meet the stated goal of ensuring that scripts run and resources are available before a swap operation occurs.
The proposed solution suggests updating the app with a method named statuscheck
to run the scripts and updating the app settings for the app to set the WEBSITE_SWAP_WARMUP_PING_PATH
and WEBSITE_SWAP_WARMUP_PING_STATUSES
with a path to the new method and appropriate response codes.
By doing so, Azure App Service will ping the statuscheck
method after a swap operation to ensure that the new code has warmed up and is ready to handle incoming traffic. If the statuscheck
method returns the appropriate response codes, the swap operation will be completed, and traffic will be routed to the new deployment slot.
Therefore, the proposed solution should meet the goal of ensuring that scripts run and resources are available before a swap operation occurs, making option B - "Yes" - the correct answer.
