Explanation:
Virtual Network: You can connect con-env1 to VNet2 and VNet3 only. This is because VNet1 is in a different region than the container app, which is East US. According to the web search results, you can only connect a container app environment to a virtual network that is in the same region as the container app1.
Therefore, VNet1 is not a valid option. VNet2 and VNet3 are both in the same region as the container app, and they have enough available IP addresses to support a container app environment.
Subnet mask: You should use /28 as the subnet mask for con-env1. This is because /28 is the smallest possible subnet mask that can accommodate a container app environment. According to the web search results, a container app environment requires a minimum of 16 IP addresses in a subnet2. A /28 subnet mask provides
16 IP addresses, while a /26 subnet mask provides 64 IP addresses, a /24 subnet mask provides 256 IP addresses, a /23 subnet mask provides 512 IP addresses, and a /16 subnet mask provides 65,536 IP addresses.
Therefore, /28 is the most efficient choice for minimizing the subnet size.

IdFix is used to perform discovery and remediation of identity objects and their attributes in an on-premises Active Directory environment in preparation for migration to Azure Active Directory. IdFix is intended for the Active Directory administrators responsible for directory synchronization with Azure Active Directory.

Topic 1, Humongous InsuranceOverview
Existing Environment
Huongous Insurance is an insurance company that has three offices in Miami, Tokoyo, and Bankok. Each has
5000 users.
Active Directory Environment
Humongous Insurance has a single-domain Active Directory forest named humongousinsurance.com. The functional level of the forest is Windows Server 2012.
You recently provisioned an Azure Active Directory (Azure AD) tenant.
Network Infrastructure
Each office has a local data center that contains all the servers for that office. Each office has a dedicated connection to the Internet.
Each office has several link load balancers that provide access to the servers.
Active Directory Issue
Several users in humongousinsurance.com have UPNs that contain special characters.
You suspect that some of the characters are unsupported in Azure AD.
Licensing Issue
You attempt to assign a license in Azure to several users and receive the following error message: "Licenses not assigned. License agreement failed for one user." You verify that the Azure subscription has the available licenses.
Requirements
Planned Changes
Humongous Insurance plans to open a new office in Paris. The Paris office will contain 1,000 users who will be hired during the next 12 months. All the resources used by the Paris office users will be hosted in Azure.
Planned Azure AD Infrastructure
The on-premises Active Directory domain will be synchronized to Azure AD.
All client computers in the Paris office will be joined to an Azure AD domain.
Planned Azure Networking Infrastructure
You plan to create the following networking resources in a resource group named All_Resources:
Default Azure system routes that will be the only routes used to route traffic A virtual network named Paris-VNet that will contain two subnets named Subnet1 and Subnet2 A virtual network named ClientResources-VNet that will contain one subnet named ClientSubnet A virtual network named AllOffices-VNet that will contain two subnets named Subnet3 and Subnet4 You plan to enable peering between Paris-VNet and AllOffices-VNet. You will enable the Use remote gateways setting for the Paris-VNet peerings.
You plan to create a private DNS zone named humongousinsurance.local and set the registration network to the ClientResources-VNet virtual network.
Planned Azure Computer Infrastructure
Each subnet will contain several virtual machines that will run either Windows Server 2012 R2, Windows Server 2016, or Red Hat Linux.
Department Requirements
Humongous Insurance identifies the following requirements for the company's departments:
Web administrators will deploy Azure web apps for the marketing department. Each web app will be added to a separate resource group. The initial configuration of the web apps will be identical. The web administrators have permission to deploy web apps to resource groups.
During the testing phase, auditors in the finance department must be able to review all Azure costs from the past week.
Authentication Requirements
Users in the Miami office must use Azure Active Directory Seamless Single Sign-on (Azure AD Seamless SSO) when accessing resources in Azure.

The Logic App Operator role only grants the ability to read, enable, disable, and run logic apps. It does not grant the ability to create logic apps. To create logic apps, you need to assign the Logic App Contributor role or a higher-level role such as Owner or Contributor. Then, References: [Built-in roles for Azure resources]

Explanation:

Box 1: storageaccount1 and storageaccount2 only
Box 2: All the storage accounts
Note: The three different storage account options are: General-purpose v2 (GPv2) accounts, General-purpose v1 (GPv1) accounts, and Blob storage accounts.
General-purpose v2 (GPv2) accounts are storage accounts that support all of the latest features for blobs, files, queues, and tables.
Blob storage accounts support all the same block blob features as GPv2, but are limited to supporting only block blobs.
General-purpose v1 (GPv1) accounts provide access to all Azure Storage services, but may not have the latest features or the lowest per gigabyte pricing.

Explanation:
Box 1 : Containers will get the IP address from the virtual network subnet CIDr which is 10.244.0.0/16 Box 2 : Services in the AKS cluster will be assigned an IP address in the service CIDR which is 10.0.0.0/16 Reference:
