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.

Suggested Answer: 
    

Box 1: await context.CallEntityAsync(input[errindex],"error")
Orchestration signals and calls an entity
Orchestrator functions can access entities by using APIs on the orchestration trigger binding.
Example:
[FunctionName("CounterOrchestration")]
public static async Task Run(
[OrchestrationTrigger] IDurableOrchestrationContext context)
{
var entityId = new EntityId(nameof(Counter), "myCounter");
// Two-way call to the entity which returns a value - awaits the response int currentValue = await context.CallEntityAsync(entityId, "Get");
Box 2: Failed -
During processing a single instance of invalid input does not cause the function to fail.
Note: RuntimeStatus: One of the following values:
Failed: The instance failed with an error.
Completed: The instance has completed normally.
Terminated: The instance was stopped abruptly.
Pending: The instance has been scheduled but has not yet started running.
Running: The instance has started running.
ContinuedAsNew: The instance has restarted itself with a new history. This state is a transient state.
Box 3: Input -
Invalid input must be available to the monitoring application.
