Develop event-based solutions - Practice Tests

Question

You want to send a message to an Event Hubs hub named services in a namespace named measureup. You have the following code:

using Azure.Messaging.EventHubs;
using Azure.Messaging.EventHubs.Producer;
using System.Text;

EventHubProducerClient producerClient = 
    new EventHubProducerClient("<CONNECTION_STRING>", "<HUB_NAME>");

You need to set the CONNECTION_STRING and HUB_NAME parameter.

Which value should you use?

Option 1

CONNECTION_STRING = Endpoint=sb://measureup.servicebus.windows.net/;EntityPath=services;
HUB_NAME = services

Option 2

CONNECTION_STRING = https://measureup.azurewebsites.net/services
HUB_NAME = measureup

Option 3
CONNECTION_STRING = Endpoint=https://measureup.azurewebsites.net?EntityPath=services;
HUB_NAME = services
Option 4
CONNECTION_STRING = sb://measureup.servicebus.windows.net/services
HUB_NAME = measureup

Question

You have the following code (line numbers are included for reference only):

01  class Program
02  {
03      static async Task Main()
04      {
05          EventHubProducerClient producerClient = new EventHubProducerClient("<CONNECTION_STRING>", "<HUB_NAME>");
06          try
07          {
08              var message = "This is a single event";
09              EventData singleEvent = new EventData(Encoding.UTF8.GetBytes(message));
10              ________________________________
11              Console.WriteLine("A single event has been published.");
12          }
13      }
14  }

You need to submit the message to the Event Hub.

Which code segment should you add at line 10?

Options

await producerClient.SendAsync(Encoding.UTF8.GetBytes(message));
await producerClient.SendAsync(new[] { singleEvent });

await producerClient.SendAsync(singleEvent);

await producerClient.SendAsync(new EventData(message));
