The correct service is Azure Load Balancer , specifically an internal load balancer . Microsoft defines the load balancer frontend IP as either public or private, and states that selecting a private IP address creates an internal load balancer. Microsoft also states that an internal load balancer distributes traffic to resources inside a virtual network and that the frontend IPs are not directly exposed to an internet endpoint. This directly satisfies the requirement to distribute inbound traffic from VNet2 to VM1 and VM2 while preventing internet exposure.
Azure Front Door and Azure Traffic Manager are global edge or DNS-based traffic distribution services and are not the correct choice for private, VNet-to-VNet load balancing. Azure Application Gateway can be private, but it is a Layer 7 HTTP/HTTPS application delivery controller; the question asks generically for even distribution of inbound traffic to two VMs through the internal network. The AZ-104 study guide maps this scenario to Implement and manage virtual networking , especially Configure name resolution and load balancing and Configure an internal or public load balancer .

Active Directory Federation Services is a feature and web service in the Windows Server Operating System that allows sharing of identity information outside a company's network.
Scenario: Technical Requirements include:
Prevent user passwords or hashes of passwords from being stored in Azure.

User1 can view blob data and upload blob data because the exhibit shows User1 has the Storage Blob Data Contributor role assigned directly at the storage account scope. Microsoft defines this built-in role as allowing a principal to read, write, and delete Azure Storage containers and blobs. Therefore, User1 has data- plane permissions for Blob Storage, including reading existing blob content and uploading new blobs.
The inherited Reader role at the resource group scope provides management-plane read access to Azure resources, but it does not grant permission to assign roles, modify storage account firewall rules, or access Azure Files data. Assigning roles requires elevated RBAC permissions such as Owner or User Access Administrator, not Reader. Modifying the storage firewall requires management-plane write permissions over the storage account, which Reader does not provide. Listing files in Azure file shares is also not included in the Storage Blob Data Contributor role because that role applies to blob containers and blobs, not Azure Files.
