  Box 1: az ts create \

  Deploy template spec

  Instead of deploying a local or remote template, you can create a template spec. The template spec is a resource in your Azure subscription that contains an ARM template. It makes it easy to securely share the template with users in your organization. You use Azure role-based access control (Azure RBAC) to grant access to the template spec. This feature is currently in preview.

  The following examples show how to create and deploy a template spec.

  First create the template spec by providing the ARM template.

  Azure CLI

  az ts create \

  --name storageSpec \

  --version "1.0" \

  --resource-group templateSpecRG \

  --location "westus2" \

  --template-file "./mainTemplate.json"

  Box 2: mainTemplate.json

  Incorrect:

  * az blueprint artifact template create \

  --blueprint-name 'MyBlueprint' \

  --artifact-name 'templateStorage' \

  --template artifacts\templateStorage.json \

  --parameters artifacts\templateStorageParams.json \

  --resource-group-art 'storageRG'

• Question 157:

  Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

  After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

  You develop and deploy an Azure App Service API app to a Windows-hosted deployment slot named Development. You create additional deployment slots named Testing and Production. You enable auto swap on the Production deployment slot.

  You need to ensure that scripts run and resources are available before a swap operation occurs.

  Solution: Enable auto swap for the Testing slot. Deploy the app to the Testing slot.

  Does the solution meet the goal?

  A. No
  B. Yes
  B. Yes

  ---

  Explanation

  Instead update the web.config file to include the applicationInitialization configuration element. Specify custom initialization actions to run the scripts.

  Note: Some apps might require custom warm-up actions before the swap. The applicationInitialization configuration element in web.config lets you specify custom initialization actions. The swap operation waits for this custom warm-up to finish before swapping with the target slot. Here's a sample web.config fragment.

  <system.webServer>

  <applicationInitialization>

  <add initializationPage="/" hostName="[app hostname]" /> <add initializationPage="/Home/About" hostName="[app hostname]" /> </applicationInitialization> </system.webServer>

• Question 158:

  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
  E. In a .NET method, call the method: BatchClient.PoolOperations.CreatePool
  F. In Python, implement the class: TaskAddParameter
  G. In the Azure CLI, run the command: az batch account 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, F: 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.

  E: BatchClient.PoolOperations does not have a CreateJob method.

• Question 160:

  You need to support the requirements for the Shipping Logic App.

  What should you use?

  A. Azure Active Directory Application Proxy
  B. Site-to-Site (S2S) VPN connection
  C. On-premises Data Gateway
  D. Point-to-Site (P2S) VPN connection
  C. On-premises Data Gateway

  ---

  Explanation

  Before you can connect to on-premises data sources from Azure Logic Apps, download and install the on-premises data gateway on a local computer. The gateway works as a bridge that provides quick data transfer and encryption between data sources on premises (not in the cloud) and your logic apps.

  The gateway supports BizTalk Server 2016.

  Note: Microsoft have now fully incorporated the Azure BizTalk Services capabilities into Logic Apps and Azure App Service Hybrid Connections.

  Logic Apps Enterprise Integration pack bring some of the enterprise B2B capabilities like AS2 and X12, EDI standards support

  Scenario: The Shipping Logic app must meet the following requirements:

  1. Support the ocean transport and inland transport workflows by using a Logic App.

  2. Support industry-standard protocol X12 message format for various messages including vessel content details and arrival notices.

  3. Secure resources to the corporate VNet and use dedicated storage resources with a fixed costing model.

  4. Maintain on-premises connectivity to support legacy applications and final BizTalk migrations.
