• Question 573:

  You are building a web application that uses the Microsoft identity platform for user authentication.

  You are implementing user identification for the web application.

  You need to retrieve a claim to uniquely identify a user.

  Which claim type should you use?

  A. oid
  B. aud
  C. idp
  D. nonce
  A. oid

  ---

  Explanation

  oid -The object identifier for the user in Azure AD. This value is the immutable and non-reusable identifier of the user. Use this value, not email, as a unique identifier for users; email addresses can change. If you use the Azure AD Graph API in your app, object ID is that value used to query profile information.

  Incorrect:

  Not A: aud - Who the token was issued for. This will be the application's client ID.

• Question 575:

  You are writing code to create and run an Azure Batch job.

  You have created a pool of compute nodes.

  You need to choose the right class and its method to submit a batch job to the Batch service.

  Which method should you use?

  A. JobOperations.EnableJobAsync(String, IEnumerable<BatchClientBehavior>,CancellationToken)
  B. JobOperations.CreateJob()
  C. CloudJob.Enable(IEnumerable<BatchClientBehavior>)
  D. JobOperations.EnableJob(String,IEnumerable<BatchClientBehavior>)
  E. CloudJob.CommitAsync(IEnumerable<BatchClientBehavior>, CancellationToken)
  E. CloudJob.CommitAsync(IEnumerable<BatchClientBehavior>, CancellationToken)

  ---

  Explanation

  A Batch job is a logical grouping of one or more tasks. A job includes settings common to the tasks, such as priority and the pool to run tasks on. The app uses the BatchClient.JobOperations.CreateJob method to create a job on your pool.

  The Commit method submits the job to the Batch service. Initially the job has no tasks.

  {

  CloudJob job = batchClient.JobOperations.CreateJob();

  job.Id = JobId;

  job.PoolInformation = new PoolInformation { PoolId = PoolId };

  job.Commit();

  }

• Question 578:

  DRAG DROP

  Your company has several websites that use a company logo image. You use Azure Content Delivery Network (CDN) to store the static image.

  You need to determine the correct process of how the CDN and the Point of Presence (POP) server will distribute the image and list the items in the correct order.

  In which order do the actions occur? To answer, move all actions from the list of actions to the answer area and arrange them in the correct order.

  Select and Place:

  Step 1: A user requests the image..

  A user requests a file (also called an asset) by using a URL with a special domain name, such as <endpoint name>.azureedge.net. This name can be an endpoint hostname or a custom domain. The DNS routes the request to the best performing POP location, which is usually the POP that is geographically closest to the user.

  Step 2: If no edge servers in the POP have the..

  If no edge servers in the POP have the file in their cache, the POP requests the file from the origin server. The origin server can be an Azure Web App, Azure Cloud Service, Azure Storage account, or any publicly accessible web server.

  Step 3: The origin server returns the..

  The origin server returns the file to an edge server in the POP.

  An edge server in the POP caches the file and returns the file to the original requestor (Alice). The file remains cached on the edge server in the POP until the time-to-live (TTL) specified by its HTTP headers expires. If the origin server didn't specify a TTL, the default TTL is seven days.

  Step 4: Subsequent requests for..

  Additional users can then request the same file by using the same URL that the original user used, and can also be directed to the same POP.

  If the TTL for the file hasn't expired, the POP edge server returns the file directly from the cache. This process results in a faster, more responsive user experience.

• Question 579:

  You are developing a software solution for an autonomous transportation system. The solution uses large data sets and Azure Batch processing to simulate navigation sets for entire fleets of vehicles.

  You need to create compute nodes for the solution on Azure Batch.

  What should you do?

  A. In the Azure portal, add a Job to a Batch account.
  B. In a .NET method, call the method: BatchClient.PoolOperations.CreateJob
  C. In Python, implement the class: JobAddParameter
  D. In Azure CLI, run the command: az batch pool create
  B. In a .NET method, call the method: BatchClient.PoolOperations.CreateJob

  ---

  Explanation

  A Batch job is a logical grouping of one or more tasks. A job includes settings common to the tasks, such as priority and the pool to run tasks on. The app uses the BatchClient.JobOperations.CreateJob method to create a job on your pool.

  Note:

  Step 1: Create a pool of compute nodes. When you create a pool, you specify the number of compute nodes for the pool, their size, and the operating system. When each task in your job runs, it's assigned to execute on one of the nodes in your pool.

  Step 2 : Create a job. A job manages a collection of tasks. You associate each job to a specific pool where that job's tasks will run. Step 3: Add tasks to the job. Each task runs the application or script that you uploaded to process the data files it downloads from your Storage account. As each task completes, it can upload its output to Azure Storage.

  Incorrect Answers:

  C: To create a Batch pool in Python, the app uses the PoolAddParameter class to set the number of nodes, VM size, and a pool configuration.

  Box 1: SAS tokens

  Custom topics use either Shared Access Signature (SAS) or key authentication. Microsoft recommends SAS, but key authentication provides simple programming, and is compatible with many existing webhook publishers.

  In this case we need the expiration time provided by SAS tokens.

  Box 2: ValidationCode handshake

  Event Grid supports two ways of validating the subscription: ValidationCode handshake (programmatic) and ValidationURL handshake (manual).

  If you control the source code for your endpoint, this method is recommended.

  Incorrect Answers:

  ValidationURL handshake (manual): In certain cases, you can't access the source code of the endpoint to implement the ValidationCode handshake. For example, if you use a third-party service (like Zapier or IFTTT), you can't programmatically respond with the validation code.
