Case Study 1 - Litware
Existing Environment
Azure Environment
Litware has 10 Azure subscriptions that are linked to the Litware.com tenant and five Azure subscriptions that are linked to the dev.litware.com tenant. All the subscriptions are in an Enterprise Agreement (EA).
The litware.com tenant contains a custom Azure role-based access control (Azure RBAC) role named Role1 that grants the DataActions read permission to the blobs and files in Azure Storage.
On-Premises Environment
The on-premises network of Litware contains the resources shown in the following table.

Network Environment
Litware has ExpressRoute connectivity to Azure.
Planned Changes and Requirements
Litware plans to implement the following changes:
* Migrate DB1 and DB2 to Azure.
* Migrate App1 to Azure virtual machines.
* Migrate the external storage used by App1 to Azure Storage.
* Deploy the Azure virtual machines that will host App1 to Azure dedicated hosts.
Authentication and Authorization Requirements
Litware identifies the following authentication and authorization requirements:
* Only users that manage the production environment by using the Azure portal must connect from a hybrid Azure AD-joined device and authenticate by using Azure Multi-Factor Authentication (MFA).
* The Network Contributor built-in RBAC role must be used to grant permissions to the network administrators for all the virtual networks in all the Azure subscriptions.
* To access the resources in Azure, App1 must use the managed identity of the virtual machines that will host the app.
* RBAC roles must be applied at the highest level possible.
Resiliency Requirements
Litware identifies the following resiliency requirements:
* Once migrated to Azure, DB1 and DB2 must meet the following requirements:
- Maintain availability if two availability zones in the local Azure region fail.
- Fail over automatically.
- Minimize I/O latency.
* App1 must meet the following requirements:
- Be hosted in an Azure region that supports availability zones.
- Be hosted on Azure virtual machines that support automatic scaling.
- Maintain availability if two availability zones in the local Azure region fail.
Security and Compliance Requirements
Litware identifies the following security and compliance requirements:
* Once App1 is migrated to Azure, you must ensure that new data can be written to the app, and the modification of new and existing data is prevented for a period of three years.
* On-premises users and services must be able to access the Azure Storage account that will host the data in App1.
* Access to the public endpoint of the Azure Storage account that will host the App1 data must be prevented.
* All Azure SQL databases in the production environment must have Transparent Data Encryption (TDE) enabled.
* App1 must NOT share physical hardware with other workloads.
Business Requirements
Litware identifies the following business requirements:
* Minimize administrative effort.
* Minimize costs.
Hotspot Question
You plan to migrate DB1 and DB2 to Azure.
You need to ensure that the Azure database and the service tier meet the resiliency and business requirements.
What should you configure? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

A company is planning on deploying a set of applications onto a set of Azure Kubernetes clusters.
The clusters would be distributed across various Azure regions. You have to recommend a storage solution for the application container images. The update container images need to be automatically replicated across all AKS clusters. Which of the following would you implement for this requirement?

A company named Contoso, Ltd. has an Azure Active Directory (Azure AD) tenant that is integrated with Microsoft 365 and an Azure subscription.
Contoso has an on-premises identity infrastructure. The infrastructure includes servers that run Active Directory Domain Services (AD DS) and Azure AD Connect.
Contoso has a partnership with a company named Fabrikam. Inc. Fabrikam has an Active Directory forest and a Microsoft 365 tenant. Fabrikam has the same on- premises identity infrastructure components as Contoso.
A team of 10 developers from Fabrikam will work on an Azure solution that will be hosted in the Azure subscription of Contoso. The developers must be added to the Contributor role for a resource group in the Contoso subscription.
You need to recommend a solution to ensure that Contoso can assign the role to the 10 Fabrikam developers. The solution must ensure that the Fabrikam developers use their existing credentials to access resources What should you recommend?

Hotspot Question
Your company has the divisions shown in the following table.

You plan to deploy a custom application to each subscription. The application will contain the following:
- A resource group
- An Azure web app
- Custom role assignments
- An Azure Cosmos DB account
You need to use Azure Blueprints to deploy the application to each subscription.
What is the minimum number of objects required to deploy the application? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

You have an Azure subscription that contains the resources shown in the following table.

You create peering between VNet1 and VNet2 and between VNet1 and VNet3.
The virtual machines host an HTTPS-based client/server application and are accessible only via the private IP address of each virtual machine.
You need to implement a load balancing solution for VM2 and VM3. The solution must ensure that if VM2 fails, requests will be routed automatically to VM3, and if VM3 fails, requests will be routed automatically to VM2.
What should you include in the solution?
