Case Study
This is a case study. Case studies are not timed separately. You can use as much exam time as you would like to complete each case. However, there may be additional case studies and sections on this exam. You must manage your time to ensure that you are able to complete all questions included on this exam in the time provided.
To answer the questions included in a case study, you will need to reference information that is provided in the case study. Case studies might contain exhibits and other resources that provide more information about the scenario that is described in the case study. Each question is independent of the other question on this case study.
At the end of this case study, a review screen will appear. This screen allows you to review your answers and to make changes before you move to the next sections of the exam. After you begin a new section, you cannot return to this section.
To start the case study
To display the first question on this case study, click the Next button. Use the buttons in the left pane to explore the content of the case study before you answer the questions. Clicking these buttons displays information such as business requirements, existing environment, and problem statements. If the case study has an All Information tab, note that the information displayed is identical to the information displayed on the subsequent tabs. When you are ready to answer a question, click the Question button to return to the question.
Background
Wide World Importers is moving all their datacenters to Azure. The company has developed several applications and services to support supply chain operations and would like to leverage serverless computing where possible.
Current environment
Windows Server 2016 virtual machine
This virtual machine (VM) runs Biz Talk Server 2016.
The VM runs the following workflows:
– Ocean Transport C This workflow gathers and validates container information including container contents and arrival notices at various shipping ports.
– Inland Transport C This workflow gathers and validates trucking information including fuel usage, number of stops, and routes.
The VM supports the following REST API calls:
– Container API C This API provides container information including weight, contents, and other attributes.
– Location API C This API provides location information regarding shipping ports of call and truck stops.
– Shipping REST API C This API provides shipping information for use and display on the shipping website.
Shipping Data
The application uses MongoDB JSON document storage database for all container and transport information.
Shipping Web Site
The site displays shipping container tracking information and container contents. The site is located at http://shipping.wideworldimporters.com
Proposed solution
The on-premises shipping application must be moved to Azure. The VM has been migrated to a new Standard_D16s_v3 Azure VM by using Azure Site Recovery and must remain running in Azure to complete the BizTalk component migrations. You create a Standard_D16s_v3 Azure VM to host BizTalk Server.
The Azure architecture diagram for the proposed solution is shown below:
Shipping Logic App
The Shipping Logic app must meet the following requirements:
– Support the ocean transport and inland transport workflows by using a Logic App.
– Support industry-standard protocol X12 message format for various messages including vessel content details and arrival notices.
– Secure resources to the corporate VNet and use dedicated storage resources with a fixed costing model.
– Maintain on-premises connectivity to support legacy applications and final BizTalk migrations.
Shipping Function app
Implement secure function endpoints by using app-level security and include Azure Active Directory (Azure AD).
REST APIs
The REST API’s that support the solution must meet the following requirements:
– Secure resources to the corporate VNet.
– Allow deployment to a testing location within Azure while not incurring additional costs.
– Automatically scale to double capacity during peak shipping times while not causing application downtime.
– Minimize costs when selecting an Azure payment model.
Shipping data
Data migration from on-premises to Azure must minimize costs and downtime.
Shipping website
Use Azure Content Delivery Network (CDN) and ensure maximum performance for dynamic content while minimizing latency and costs.
Issues
Windows Server 2016 VM
The VM shows high network latency, jitter, and high CPU utilization. The VM is critical and has not been backed up in the past. The VM must enable a quick restore from a 7-day snapshot to include in-place restore of disks in case of failure.
Shipping website and REST APIs
The following error message displays while you are testing the website:
You need to support the requirements for the Shipping Logic App.
What should you use?
A . Azure Active Directory Application Proxy
B . Point-to-Site (P2S) VPN connection
C . Site-to-Site (S2S) VPN connection
D . On-premises Data Gateway
Answer: D
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:
– Support the ocean transport and inland transport workflows by using a Logic App.
– Support industry standard protocol X12 message format for various messages including vessel content details and arrival notices.
– Secure resources to the corporate VNet and use dedicated storage resources with a fixed costing model.
– Maintain on-premises connectivity to support legacy applications and final BizTalk migrations.
