220-1102 Practice Question: A technician is trying to run a legacy 16-bit…
This 220-1102 practice question tests your understanding of a technician is trying to run a legacy 16-bit…. 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 technician is trying to run a legacy 16-bit accounting application on a 64-bit version of Windows 10 Pro. The application fails to start with a 'This app can't run on your PC' error. The application is critical and there is no 64-bit version available. Which of the following is the BEST solution to allow this application to run?
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
Distractor review
Run the application in Windows 7 compatibility mode.
Compatibility mode only adjusts settings for older versions of Windows; it does not enable 16-bit support on 64-bit Windows, which is a fundamental architecture limitation.
B
Distractor review
Enable NTVDM (NT Virtual DOS Machine) in Windows Features.
NTVDM is not available on 64-bit versions of Windows; it was only present in 32-bit versions, so this option is not possible.
C
Best answer
Install the application in a virtual machine running a 32-bit version of Windows.
A 32-bit virtual machine includes the WOW subsystem that can run 16-bit applications, providing full compatibility without affecting the host OS.
D
Distractor review
Use the Program Compatibility Troubleshooter to detect and apply fixes.
The compatibility troubleshooter can resolve some issues like incorrect permissions or settings, but it cannot overcome the architectural limitation of 64-bit Windows not supporting 16-bit code.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
Run the application in Windows 7 compatibility mode.
Compatibility mode only adjusts settings for older versions of Windows; it does not enable 16-bit support on 64-bit Windows, which is a fundamental architecture limitation.
- ✗
Enable NTVDM (NT Virtual DOS Machine) in Windows Features.
NTVDM is not available on 64-bit versions of Windows; it was only present in 32-bit versions, so this option is not possible.
- ✗

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.

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: Install the application in a virtual machine running a 32-bit version of Windows. — 64-bit versions of Windows do not support 16-bit applications due to the removal of the NTVDM subsystem. The most practical solution is to run the application in a virtual machine with a 32-bit version of Windows, which includes WOW (Windows on Windows) to support 16-bit executables.
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.
