Exam AZ-304 topic 5 question 6 discussion

Here you go. I think the key word in the requirement is 'temporary' therefore it fits the bill. https://docs.microsoft.com/en-us/azure/app-service/overview-local-cache#how-the-local-cache-changes-the-behavior-of-app-service The local cache is read-write. However, any modification is discarded when the app moves virtual machines or gets restarted. Do not use the local cache for apps that store mission-critical data in the content store. D:\home\LogFiles and D:\home\Data contain log files and app data. The two subfolders are stored locally on the VM instance, and are copied to the shared content store periodically. Apps can persist log files and data by writing them to these folders. However, the copy to the shared content store is best-effort, so it is possible for log files and data to be lost due to a sudden crash of a VM instance.

Yup, but you still can view it: https://docs.microsoft.com/en-us/learn/modules/azure-diagnose-application-startup-errors-with-kudu-console/5-exercise-diagnose-application-event-log-using-kudu-console

You can create and append data into the files located or created in the home directory. I tested it on my own subscription. I created an application that in response to a click on a button creates a file (C:\home\site\wwwroot\newfile.txt)
