220-1101 Question 350
Single answer4.1 Explain virtualization concepts.A small business wants to run a legacy accounting application that only works on Windows 7, but the company standard is now Windows 11 Pro laptops. The application must be isolated from the user's main operating system to reduce risk, and the technician wants to avoid dual-booting so employees can use both environments at the same time. Which solution BEST meets these requirements?
- A
Create a Windows 7 virtual machine in a hypervisor on the Windows 11 laptop
- B
Install Windows 7 and Windows 11 in a dual-boot configuration
- C
Use BitLocker on the Windows 11 laptop and install the application directly on the host OS
- D
Replace the Windows 11 laptops with thin clients and run the application from local storage
Show answer and explanation
Correct answer: A
Explanation
The best answer is to create a Windows 7 virtual machine on the Windows 11 Pro laptop. In A+ Core 1 virtualization concepts, a virtual machine is a software-defined computer that runs as a guest OS on top of a host system by using a hypervisor. This approach is commonly used for legacy application support, isolation, testing, and running multiple operating systems concurrently on one physical device. Dual-booting is a real option for multiple operating systems, but it does not allow simultaneous use and is less flexible for this scenario. Security tools such as BitLocker protect data at rest but do not provide virtualization or legacy OS compatibility. Best practices from major platform vendors such as Microsoft, VMware, and Oracle commonly describe VMs as appropriate for application compatibility testing, sandboxing, and legacy workload support, provided the hardware supports virtualization and the organization properly licenses the guest OS.
- A. Correct.
Correct. Running Windows 7 as a guest in a virtual machine allows the legacy application to operate in its required OS while remaining separated from the Windows 11 host. This also lets the user run both environments simultaneously, which directly addresses the requirement to avoid dual-booting. Virtual machines are a common way to provide compatibility and isolation for older applications.
- B. Incorrect.
Incorrect. Dual-booting would require the user to restart the laptop and choose one operating system at startup, so the user could not access Windows 11 and Windows 7 at the same time. It also does not provide the same convenient application isolation that a virtual machine does for this use case.
- C. Incorrect.
Incorrect. BitLocker provides drive encryption, not operating system or application compatibility. Installing the legacy application directly on Windows 11 does not solve the requirement that the application only works on Windows 7, and it does not create the desired isolated environment.
- D. Incorrect.
Incorrect. Thin clients are designed to rely primarily on centralized resources rather than local application execution and storage. Replacing laptops with thin clients does not directly solve the need to run a Windows 7 environment locally on existing Windows 11 systems, and 'run the application from local storage' conflicts with the typical thin-client model.
