To meet the goal of preventing connections to App1 when Computer1 is connected to the home network, you would need to create a rule that blocks the application on the home network. Allowing the application to communicate through the firewall on a Private network will not achieve this goal, as the home network is typically categorized as a Private network. Thus, the solution proposed does not meet the stated goal.

To assign User1 the right to restore files and folders on Server1 and Server2, creating a Group Policy Object (GPO), linking it to the Servers OU, and modifying the User Rights Assignment in the GPO is an effective solution. By linking the GPO to the Servers OU, it ensures that the policy settings apply to Server1 and Server2. Modifying the 'Restore files and directories' setting in the User Rights Assignment and granting this right to User1 will fulfill the requirement. Therefore, the correct answer is Yes.

Adding User1 to the Backup Operators group in contoso.com would give User1 rights to backup and restore files on domain controllers but not necessarily on the member servers like Server1 and Server2, unless those servers are domain controllers themselves. To grant User1 the right to restore files and folders specifically on Server1 and Server2, User1 should be added to the Backup Operators group on those specific servers. Therefore, this solution does not meet the goal.

To assign User1 the right to restore files and folders on Server1 and Server2, the correct approach is to create a Group Policy object (GPO) and link it to the organizational unit (OU) that contains the computer accounts of Server1 and Server2. In this case, both server computer accounts are in the 'Servers' OU. Linking the GPO to the 'Operations Users' OU, which contains user accounts, will not apply the needed permissions to the servers. Therefore, the solution of creating a GPO and linking it to the 'Operations Users' OU does not meet the goal.
Deploying a separate Windows container for each application does not fully meet the goal of isolating the resources of the applications from the physical host. Windows containers share the same kernel with the host operating system, which means there is no complete isolation from the physical host. Additionally, while containers provide some level of isolation between applications, they do not provide the hardware-level isolation required to prevent one application from accessing the resources of another application effectively. To achieve the required isolation, Hyper-V containers should be used instead, as they provide both the security of running each container in a lightweight virtual machine and ensuring that the resources of the applications are fully isolated from the physical host and from each other.
