Exam AZ-204 topic 2 question 43 discussion

Actual exam question from Microsoft's AZ-204
Question #: 43
Topic #: 2
[All AZ-204 Questions]

HOTSPOT -
You are developing an Azure Durable Function based application that processes a list of input values. The application is monitored using a console application that retrieves JSON data from an Azure Function diagnostic endpoint.
During processing a single instance of invalid input does not cause the function to fail. Invalid input must be available to the monitoring application.
You need to implement the Azure Durable Function and the monitoring console application.
How should you complete the code segments? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

I'd say: SetOutput() == Completed result.output The function needs to return the one invalid input, so you could use either SetOutput or SetCustomStatus, but custom status is not available after the function completes. The one invalid input does not cause the function to fail, therefore Completed.

async functions needs an await part. SetOutput() won't qualify for that as function.

you've got await in "var json = await response.Content.ReadAsStringAsync();"

I choose setCustomStatus/Completed/customStatus, setCustomStatus make invaluid input available to monitoring, response.EnsureSuccessStatusCode() would throw Exception if the result.runtimeStatus != "Complete" so I choose result.runtimeStatus == "Completed" amd return result.customStatus.

The output of the function has to match the method return type. It cannot be SetOutput. You can use CustomStatus, since the other 2 do not make sense. And the output is available on completion since the function does not throw an exception. But because the function return type is List<string>, and it may be used for another purpose, we use the custom status to get the invalid input. Also, the custom status is available after the function completes. https://learn.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-http-api#get-instance-status

I check it and setcustomstatus makes sense, cause they want to show the input that is causing errors (see link below). Apart of that, the ensuresuccessstatuscode will throw an exception if it fails, so I would go with "completed" and output https://learn.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-custom-orchestration-status?tabs=csharp https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpresponsemessage.ensuresuccessstatuscode?view=net-8.0

1. SetCustomStatus. There is no point in calling context.CallEntityAsync with "error" as parameter before knowing if error occured or not 2. Failed (only negative status) 3. runTimeStatus ( This is the only property we are sure that dynamic object posess. We don't know the custom response from the url)

For those who are wondering if it's a SignalEntity, it's not: SignalEntity(EntityId, DateTime, String, Object) Signals an operation to be performed by an entity at a specified time. Any result or exception is ignored (fire and forget). We're clearly waiting for completion here, so have to use CallEntity,
