A user reports that a legacy line-of-business application designed for Windows 7 is failing to run on a Windows 10 Pro workstation. The user receives the error message 'This app can't run on your PC'. The technician confirms the application is not digitally signed and is 32-bit. Which of the following is the BEST built-in method to allow this application to run without installing additional software?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Best answer
Right-click the application executable, select Properties, go to the Compatibility tab, and enable 'Run this program in compatibility mode for' Windows 7
This method uses the built-in Compatibility Troubleshooter to emulate an older Windows environment, which often resolves the 'This app can't run on your PC' error for legacy 32-bit applications.
Distractor review
Install Windows 7 in a virtual machine and run the application inside the VM
While this would work, it requires additional software (Hyper-V or third-party VM) and system resources, and it is not the simplest built-in method. The question asks for the best built-in method.
Distractor review
Download and run the Microsoft Application Compatibility Toolkit to create a custom fix
The ACT is a separate download from Microsoft and is not built into Windows 10. It is a more advanced tool meant for enterprise deployment, not the quickest built-in solution.
Distractor review
Reinstall Windows 10 from scratch to remove any compatibility blockers
Reinstalling Windows 10 would not fix the application compatibility issue, as the problem is with the application itself, not the OS installation. This is an extreme and incorrect step.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?
Question 2
A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)
Question 3
A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?
Question 4
A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?
Question 5
A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?
Question 6
A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?
FAQ
Questions learners often ask
What does this 220-1101 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Right-click the application executable, select Properties, go to the Compatibility tab, and enable 'Run this program in compatibility mode for' Windows 7 — Windows 10 includes a Compatibility Mode feature that allows older applications to run as if they were on a previous version of Windows. The simplest and most effective built-in method is to right-click the application's executable or shortcut, go to Properties > Compatibility tab, and check 'Run this program in compatibility mode for' and select Windows 7. This often resolves compatibility issues without needing a virtual machine or additional tools. Option A correctly describes this process. Installing Windows 7 in a VM (option B) would work but requires additional resources and is not a built-in method without installing Hyper-V or another hypervisor. The Application Compatibility Toolkit (option C) is a separate download and not built-in. Reinstalling Windows 10 (option D) is unnecessary and would not fix the issue.
