Microsoft Developing Solutions for Microsoft Azure : AZ-204

Case Study 5 - Wide World Importers
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 - This workflow gathers and validates container information including
container contents and arrival notices at various shipping ports.
* Inland Transport - 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 - This API provides container information including weight, contents, and other
attributes.
* Location API - This API provides location information regarding shipping ports of call and truck
stops.
* Shipping REST API - 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. Site-to-Site (S2S) VPN connection
• B. Point-to-Site (P2S) VPN connection
• C. Azure Active Directory Application Proxy
• D. On-premises Data Gateway

Drag and Drop Question
You are implementing an order processing system. A point of sale application publishes orders to topics in an Azure Service Bus queue. The Label property for the topic includes the following data:

The system has the following requirements for subscriptions:

You need to implement filtering and maximize throughput while evaluating filters.
Which filter types should you implement? To answer, drag the appropriate filter types to the correct subscriptions. Each filter type may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Hotspot Question
You have developed a Web App for your company. The Web App provides services and must run in multiple regions.
You want to be notified whenever the Web App uses more than 85 percent of the available CPU cores over a 5 minute period. Your solution must minimize costs.
Which command should you use? To answer, select the appropriate settings in the answer area.
NOTE: Each correct selection is worth one point.

Hotspot Question
You are developing an ASP.NET Core web application. You plan to deploy the application to Azure Web App for Containers.
The application needs to store runtime diagnostic data that must be persisted across application restarts. You have the following code:

You need to configure the application settings so that diagnostic data is stored as required.
How should you configure the web app's settings? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

A development team is developing an application. The application will be storing its data in Azure Table storage. Below are the fields that are going to be stored in the table
- Region
- Email address
- Phone number
The following snippet of code needs to be completed that would be used to insert a batch of records.

Which of the following will go into Slot3?

• A. ExecuteBatch
• B. Execute
• C. Insert
• D. InsertOrMerge
