Box 1: 1
App1 will only be accessible from the internet. App1 has the following connection requirements:

• 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.
App1 will have six instances: three in the East US Azure region and three in the West Europe Azure region.

Note: Azure Traffic Manager is a DNS-based traffic load balancer. This service allows you to distribute traffic to your public facing applications across the global Azure regions.

Box 2: 2
For production workloads, run at least two gateway instances.
A single Application Gateway deployment can run multiple instances of the gateway.
Use one Application Gateway in East US Region, and one in the West Europe region.

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.

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.
-

Explanation:

Box 1: SQL Managed Instance
Scenario: 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.
The auto-failover groups feature allows you to manage the replication and failover of a group of databases on a server or all databases in a managed instance to another region. It is a declarative abstraction on top of the existing active geo-replication feature, designed to simplify deployment and management of geo-replicated databases at scale. You can initiate a geo-failover manually or you can delegate it to the Azure service based on a user-defined policy. The latter option allows you to automatically recover multiple related databases in a secondary region after a catastrophic failure or other unplanned event that results in full or partial loss of the SQL Database or SQL Managed Instance availability in the primary region.
Box 2: Business critical
SQL Managed Instance is available in two service tiers:
General purpose: Designed for applications with typical performance and I/O latency requirements. Business critical: Designed for applications with low I/O latency requirements and minimal impact of underlying maintenance operations on the workload.

Overview
Fabrikam, Inc. is an engineering company that has offices throughout Europe. The company has a main office in London and three branch offices in Amsterdam, Berlin, and Rome.

Existing Environment:
-Active Directory Environment
-The network contains two Active Directory forests named corp.fabrikam.com and rd.fabrikam.com. There are no trust relationships between the forests.
-Corp.fabrikam.com is a production forest that contains identities used for internal user and computer authentication.
-Rd.fabrikam.com is used by the research and development (R&D) department only. The R&D department is restricted to using on-premises resources only.

Existing Environment:
-Network Infrastructure
-Each office contains at least one domain controller from the corp.fabrikam.com domain. The main office contains all the domain controllers for the rd.fabrikam.com forest.
-All the offices have a high-speed connection to the internet.
-An existing application named WebApp1 is hosted in the data center of the London office. WebApp1 is used by customers to place and track orders. WebApp1 has a web tier that uses Microsoft Internet information Services (IIS) and a database tier that runs Microsoft SQL Server 2016. The web tier and the database tier are deployed to virtual machines that run on Hyper-V.
-The IT department currently uses a separate Hyper-V environment to test updates to WebApp1.
-Fabrikam purchases all Microsoft licenses through a Microsoft Enterprise Agreement that includes Software Assurance.

Existing Environment:
Problem Statements
The use of WebApp1 is unpredictable. At peak times, users often report delays. At other times, many resources for WebApp1 are underutilized.

Requirements:
-Planned Changes
-Fabrikam plans to move most of its production workloads to Azure during the next few years, including virtual machines that rely on Active Directory for authentication.
-As one of its first projects, the company plans to establish a hybrid identity model, facilitating an upcoming Microsoft 365 deployment.

-Whenever possible, solutions must be deployed to Azure by using the Standard pricing tier of Azure App Service.
-An email distribution group named IT Support must be notified of any issues relating to the directory synchronization services.
-In the event that a link fails between Azure and the on-premises network, ensure that the virtual machines hosted in Azure can authenticate to Active Directory.
-Directory synchronization between Azure Active Directory (Azure AD) and corp.fabrikam.com must not be affected by a link failure between Azure and the on-premises network.
