<br />
Box 1: Azure AD Identity Protection Azure AD Identity Protection helps you manage the roll-out of Azure AD Multi-Factor Authentication (MFA) registration by configuring a Conditional Access policy to require MFA registration no matter what modern authentication app you are signing in to. Scenario: Users that manage the production environment by using the Azure portal must connect<br />
from a hybrid Azure AD-joined device and authenticate by using Azure Multi-Factor Authentication<br />
Box 2: Sign-in risk policy... Scenario: The Litware.com tenant has a conditional access policy named capolicy1. Capolicy1 (MFA). requires that when users manage the Azure subscription for a production environment by using the Azure portal, they must connect from a hybrid Azure AD-joined device. Identity Protection policies we have two risk policies that we can enable in our directory. Sign-in risk policy User risk policy<br />

Private Endpoint securely connect to storage accounts from on-premises networks that connect to<br />
the VNet using VPN or ExpressRoutes with private-peering.<br />
Private Endpoint also secure your storage account by configuring the storage firewall to block all<br />
connections on the public endpoint for the storage service. https://docs.microsoft.com/en-us/azure/expressroute/expressroute-faqs#microsoft-peering

Scenario: To access the resources in Azure, App1 must use the managed identity of the virtual machines that will host the app. Managed identities provide an identity for applications to use when connecting to resources that support Azure Active Directory (Azure AD) authentication. Applications may use the managed identity to obtain Azure AD tokens.<br />

<br />
Scenario: All Azure SQL databases in the production environment must have Transparent Data Encryption (TDE) enabled.<br />
<br />
Step 1: Create an Azure policy definition that uses the deployIfNotExists identity.<br />
The first step is to define the roles that deployIfNotExists and modify needs in the policy definition to successfully deploy the content of your included template.<br />
<br />
Step 2: Create an Azure policy assignment<br />
When creating an assignment using the portal, Azure Policy both generates the managed identity and grants it the roles defined in roleDefinitionIds.<br />
<br />
Step 3: Invoke a remediation task<br />
Resources that are non-compliant to a deployIfNotExists or modify policy can be put into a compliant state through Remediation. Remediation is accomplished by instructing Azure Policy to run the deployIfNotExists effect or the modify operations of the assigned policy on your existing resources and subscriptions, whether that assignment is to a management group, a subscription, a resource group, or an individual resource. During evaluation, the policy assignment with deployIfNotExists or modify effects determines if there are non-compliant resources or subscriptions. When non-compliant resources or subscriptions are found, the details are provided on the Remediation page. https://docs.microsoft.com/en-us/azure/governance/policy/how-to/remediate-resources<br />

Box 1: 3<br />
<br />
Scenario: App1 must meet the following requirements: Be hosted in an Azure region that supports availability zones. Maintain availability if two availability zones in the local Azure region fail. A host group is a resource that represents a collection of dedicated hosts. You create a host group in a region and an availability zone, and add hosts to it. Use Availability Zones for fault isolation Availability zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. A host group is created in a single availability zone. Once created, all hosts will be placed within that zone. To achieve high availability across zones, you need to create multiple host groups (one per zone) and spread your hosts accordingly.<br />
<br />
Scenario: App1 must meet the following requirements: Box 2: 1 Be hosted on Azure virtual machines that support automatic scaling. An Azure virtual machine scale set can automatically increase or decrease the number of VM instances that run your application. This automated and elastic behavior reduces the management overhead to monitor and optimize the performance of your application.<br />
