220-1102 Practice Question: After a Windows 10 update, a user reports that a…
This 220-1102 practice question tests your understanding of after a windows 10 update, a user reports that a…. 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.
After a Windows 10 update, a user reports that a legacy business application displays the error 'This app can't run on your PC' when launched. The technician has already run System File Checker (sfc) and DISM without issues. Which of the following should the technician try FIRST to resolve the compatibility 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
Reinstall the application
Reinstalling the same version of the application will not resolve incompatibility caused by the Windows update, so this step is not productive.
B
Best answer
Run the application in compatibility mode for an older Windows version
Compatibility mode allows an older application to run as if it were on a previous Windows version, often resolving errors like 'This app can't run on your PC'.
C
Distractor review
Perform a Windows Update rollback
Rolling back the update might resolve the issue but is more extreme and should be considered after exhausting other options, as the update may contain important security fixes.
D
Distractor review
Disable User Account Control (UAC)
Disabling UAC does not address compatibility issues and weakens system security; it is not a recommended troubleshooting step for this error.

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: Run the application in compatibility mode for an older Windows version — Running the application in compatibility mode for an older Windows version (e.g., Windows 7 or 8) is a common first step to resolve compatibility issues after an update. This setting can be configured by right-clicking the executable, selecting Properties > Compatibility tab, and choosing a previous OS version. Reinstalling the application is unlikely to help if the issue is OS-level incompatibility. Rolling back the update may be effective but is more disruptive and should not be the first step. Disabling UAC is a security risk and not a recommended solution.
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.
