You are developing a sales application that will contain several Azure cloud services and handle different components of a transaction. Different cloud services will process customer orders, billing, payment, inventory, and shipping.
You need to recommend a solution to enable the cloud services to asynchronously communicate transaction information by using XML messages.
What should you include in the recommendation?

Case Study 3 - Contoso
Existing Environment: Technical Environment
The on-premises network contains a single Active Directory domain named contoso.com.
Contoso has a single Azure subscription.
Existing Environment: Business Partnerships
Contoso has a business partnership with Fabrikam, Inc. Fabrikam users access some Contoso applications over the internet by using Azure Active Directory (Azure AD) guest accounts.
Requirements: Planned Changes
Contoso plans to deploy two applications named App1 and App2 to Azure.
Requirements: App1
App1 will be a Python web app hosted in Azure App Service that requires a Linux runtime. Users from Contoso and Fabrikam will access App1.
App1 will access several services that require third-party credentials and access strings. The credentials and access strings are stored in Azure Key Vault.
App1 will have six instances: three in the East US Azure region and three in the West Europe Azure region.
App1 has the following data requirements:
* Each instance will write data to a data store in the same availability zone as the instance.
* Data written by any App1 instance must be visible to all App1 instances.
App1 will only be accessible from the internet. App1 has the following connection requirements:
* Connections to App1 must pass through a web application firewall (WAF).
* Connections to App1 must be active-active load balanced between instances.
* All connections to App1 from North America must be directed to the East US region. All other connections must be directed to the West Europe region.
Every hour, you will run a maintenance task by invoking a PowerShell script that copies files from all the App1 instances. The PowerShell script will run from a central location.
Requirements: App2
App2 will be a NET app hosted in App Service that requires a Windows runtime. App2 has the following file storage requirements:
* Save files to an Azure Storage account.
* Replicate files to an on-premises location.
* Ensure that on-premises clients can read the files over the LAN by using the SMB protocol.
You need to monitor App2 to analyze how long it takes to perform different transactions within the application. The solution must not require changes to the application code.
Application Development Requirements
Application developers will constantly develop new versions of App1 and App2. The development process must meet the following requirements:
* A staging instance of a new application version must be deployed to the application host before the new version is used in production.
* After testing the new version, the staging version of the application will replace the production version.
* The switch to the new application version from staging to production must occur without any downtime of the application.
Identity Requirements
Contoso identifies the following requirements for managing Fabrikam access to resources:
* Every month, an account manager at Fabrikam must review which Fabrikam users have access permissions to App1. Accounts that no longer need permissions must be removed as guests.
* The solution must minimize development effort.
Security Requirement
All secrets used by Azure services must be stored in Azure Key Vault.
Services that require credentials must have the credentials tied to the service instance. The credentials must NOT be shared between services.
Hotspot Question
You are evaluating whether to use Azure Traffic Manager and Azure Application Gateway to meet the connection requirements for App1.
What is the minimum numbers of instances required for each service? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

You plan to deploy an Azure BareMetal Infrastructure instance that will host the data tier of a business-critical workload. The application tier of the workload will be hosted on Azure virtual machines.
You need to configure the virtual machines to minimize network latency between the application tier and the data tier.
What should you use?

Hotspot Question
You need to deploy an instance of SQL Server on Azure Virtual Machines. The solution must meet the following requirements:
- Support 15,000 disk IOPS.
- Support SR-IOV.
- Minimize costs.
What should you include in the solution? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Hotspot Question
Your company, named Contoso, Ltd., has an Azure subscription that contains the following resources:
- An Azure Synapse Analytics workspace named contosoworkspace1
- An Azure Data Lake Storage account named contosolake1
- An Azure SQL database named contososql1
The product data of Contoso is copied from contososql1 to contosolake1.
Contoso has a partner company named Fabrikam Inc. Fabrikam has an Azure subscription that contains the following resources:
- A virtual machine named FabrikamVM1 that runs Microsoft SQL Server
2019
- An Azure Storage account named fabrikamsa1
Contoso plans to upload the research data on FabrikamVM1 to contosolake1. During the upload, the research data must be transformed to the data formats used by Contoso.
The data in contosolake1 will be analyzed by using contosoworkspace1.
You need to recommend a solution that meets the following requirements:
- Upload and transform the FabrikamVM1 research data.
- Provide Fabrikam with restricted access to snapshots of the data in
contosoworkspace1.
What should you recommend for each requirement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
