220-1102 Practice Question: A technician is troubleshooting a user's Windows…
This 220-1102 practice question tests your understanding of a technician is troubleshooting a user's windows…. 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 troubleshooting a user's Windows 10 workstation where a legacy business application fails to launch. The application was working yesterday, but after a recent Windows Update was installed automatically overnight, the application now displays an error indicating it is not compatible. The technician has already rolled back the update, but the application still will not launch. Which of the following should the technician try NEXT to resolve the issue?
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 System File Checker (SFC) to repair any corrupted system files.
SFC is used to repair system file corruption, but the error suggests compatibility, not corruption. It is not the most direct next step.
B
Best answer
Use the Program Compatibility Troubleshooter to set the application to run in compatibility mode.
The Compatibility Troubleshooter is designed to diagnose and resolve issues where programs that worked on older Windows versions fail after updates. It can apply the correct compatibility settings.
C
Distractor review
Uninstall and reinstall the legacy application to restore its original configuration.
Reinstalling is more time-consuming and may not fix the compatibility issue if the update changed the system environment. It should be a later step.
D
Distractor review
Check for updated drivers for the application from the manufacturer's website.
The application is a software program, not a driver. Driver updates are not relevant here.

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.

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: Use the Program Compatibility Troubleshooter to set the application to run in compatibility mode. — After rolling back an update, if the application still does not work, the next step is to use the Program Compatibility Troubleshooter. This tool can automatically detect and apply compatibility settings (e.g., running the app as an administrator or in compatibility mode for an older Windows version). Reinstalling the application might work but is more drastic and may not address the compatibility issue. Checking for newer drivers is unrelated because the issue is with the application, not drivers. Running SFC is for system file corruption, but the problem is more likely compatibility-related.
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.
