Exam AZ-301 topic 6 question 47 discussion

both the requirements "✑ Must read and write temporary files to the local file system. ✑ Must write to the Windows Application event log." point o an IAAS solution and the only IAAS solution in there is virtual machine scale set. so the given answer is correct

Answer is Azure Web App, because: - Azure Web App can write Application log - https://docs.microsoft.com/es-es/azure/app-service/troubleshoot-diagnostic-logs - Azure web App can read/write files to local file system - https://github.com/projectkudu/kudu/wiki/Understanding-the-Azure-App-Service-file-system - Azure web app is less expansive that a VM scale set (VM scale is thinked for a long number of VM)

A. an Azure virtual machine scale set

A is correct, the key word here to be noticed is "Windows Event Log."

A is correct .

A -https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/policy-reference

I'm willing to go for answer D: Web apps can log to eventlog, you access them through KUDU (https://www.c-sharpcorner.com/article/azure-app-service-troubleshoot-using-event-log/), and it's cheaper than a scaleset, i can host this on one machine.

Any solution needs to have IaaS i.e. VM involved. Azure Function is serverless until it's in isolated plan (which is not specified here). App service also is PaaS and does not expose underlying hardware so both cannot write to Windows Event log. The answer should have put simply Virtual machine as there is no requirement mentioned for scale set. Even it says minimized cost but that is only option having VM involved so answer is correct.

I mean Windows Application event log. for B is not correct

function can not write to the termporay file system

Option B. an Azure function is the Correct

Ain't application logging in webapp not the same as windows application event logging? http://blog.mohlsen.com/viewing-application-event-logs-on-azure/

I think B can accomplish …B is correct.

For me is an App Service Environment "Enable application logging (Windows) To enable application logging for Windows apps in the Azure portal, navigate to your app and select App Service logs." https://docs.microsoft.com/en-us/azure/app-service/troubleshoot-diagnostic-logs

Function don't write to Windows Event log

I would also say B. what do you say about it?

B. an Azure function , is correct.
