You’re configuring Azure Functions for an order-processing workflow. You need a hosting plan that bills based on the total number of core seconds and memory allocation across all instances, without separate execution charges. Which Azure Functions hosting plan should you choose?

You’re running a serverless app in Azure Functions and noticing some delay in how fast your app scales during high traffic. Which of the following statements is true about how the scale controller works in Azure Functions?

A function app can only scale out to a maximum of 200 instances on the Consumption plan. What is the maximum number of instances a Premium plan can scale out to?

You’re configuring triggers and bindings for a function app. Each time a new message arrives in Azure Queue storage, you want to create a new row in Azure Table storage to store some data from the queue message. Which trigger and binding should you use in this scenario? (Choose two).

You’re configuring a newly created function app by accessing the Configuration blade. Which application setting contains the storage account connection string for the Azure Functions runtime to use in everyday operations?

John is configuring a trigger for his newly created function app. He enters the following code in the run.csx file:

using Microsoft.Extensions.Logging;
public static DemoMessage Run(string myQueueItem, ILogger log)
{
return new DemoMessage() {
PartitionKey = “Messages”,
RowKey = Guid.NewGuid().ToString(),
Message = myQueueItem.ToString() };
}
public class DemoMessage
{
public string PartitionKey { get; set;
}
public string RowKey { get; set; }
public string Message{ get; set; }
}

What happens when the return value of the method is passed to the output binding? (Choose two).

You are working in Azure Functions and need to add a Timer-triggered function to an existing Function App. Which of the following steps correctly describes what you should do to implement the Timer trigger?

You’re configuring an HTTP trigger in a function app. After setting the HTTP trigger, you view the function.json file to verify the trigger.
