220-1102 Practice Question: That a legacy line-of-business application…
This 220-1102 practice question tests your understanding of that a legacy line-of-business application…. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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.
A
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.
B
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.
C
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.
D
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.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.

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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

The technician completes the update on a file server and verifies the server is functioning normally. According to change management best practices, what documentation should the technician complete?
Question 2
A company's change management policy requires all server changes to be approved by the Change Advisory Board (CAB). A technician discovers that a critical database server's operating system needs a security patch to comply with a new regulatory requirement that takes effect in one week.

FAQ
Questions learners often ask
What does this 220-1102 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.
What should I do if I get this 220-1102 question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 220-1102 NAT questions on configuration and troubleshooting.
