NEW QUESTION 7
You need to resolve the delivery API error. What should you do?

• A. Implement simple retry by using the EnableRetryOnFailure feature of Entity Framework.
• B. Implement exponential backoff by using the EnableRetryOnFailure feature of Entity Framework.
• C. Implement the Circuit Breaker pattern by using the EnableRetryOnFailure feature of Entity Framework.
• D. Invoke accustom execution strategy in Entity Framework.

Answer: A

Explanation: Scenario: The Delivery API intermittently throws the following exception:

A useful method to get rid of this error is to use RETRY LOGIC of Entity Framework 1.1.0 services.AddDbContext<DbContext>(options => options.UseSqlServer('yourconnectionstring',
…sqlServerOptionsAction: sqlOptions =>
…{
……sqlOptions.EnableRetryOnFailure(
………maxRetryCount: 5,
………maxRetryDelay: TimeSpan.FromSeconds(30),
………errorNumbersToAdd: new List<int>() { 19 });
…}));
In Retry logic, error 19 is not included. So you have to pass the error code 19 to set retry logic for error code 19.

NEW QUESTION 9
You develop an IoT solution by using Node.js. The solution is ready to deploy to the production environment.
You must implement the device twin capabilities of Azure IoT Hub. You must register a sensor named Sensor00. The IoT Hub name is Hub01.
You need to register the endpoint with ContosoHub01 so that you can configure them from your solution. Which four commands should you use to develop the solution? To answer, move the appropriate commands from the list of commands to the answer area and arrange them in the correct order.

Answer:

Explanation: Step 1: az extension add --name azure-cli-iot-ext
Run the following command in the command-line environment where you are using the Azure CLI to install the IoT extension:
az extension add --name azure-cli-iot-ext Step 2: az iot hub device-identity create
--hub-name {Hub01}
--device-id Sensor00
Create a new device identity called myDeviceId and retrieve the device connection string with these commands:
az iot hub device-identity create --device-id myDeviceId --hub-name {Your IoT Hub name}
az iot hub device-identity show-connection-string --device-id myDeviceId --hub-name {Your IoT Hub name}
-o table
Step 3: az iot hub device-identity show-connection-string
--hub-name {Hub01}
--device-id Sensor00
--output table Step 4:
Create the service app
In this section, you create a Node.js console app that adds location metadata to the device twin. npm install azure-iothub --save

NEW QUESTION 14
A construction company creates three-dimensional models from photographs and design diagrams of buildings. The company plans to store high-resolution photographs and blueprint files in Azure Blob Storage. The files are currently stored in the construction company’s office.
You are developing a tool to connect to Azure Storage, create container, and then upload the files. The tool must remain responsive to the end user while it is running and performing remote I/O operations. It must also wait for methods to complete before continuing.
You need to complete the configuration.
How should you complete the code? To answer, select the appropriate options in the answer area. NOTE: Each correct solution is worth one point.

Answer:

Explanation: Box 1: ProcessAsync();
Box 2: await cloudBlobContainer.CreatAsync();
If you specify that a method is an async method by using the async modifier, you enable the following two capabilities.
The marked async method can use await to designate suspension points. The await operator tells the compiler that the async method can't continue past that point until the awaited asynchronous process is complete. In the meantime, control returns to the caller of the async method.
The suspension of an async method at an await expression doesn't constitute an exit from the method, and finally blocks don’t run.
The marked async method can itself be awaited by methods that call it. References:
