The answer is to install the app normally, as 32-bit apps are fully supported on 64-bit Windows 10. This works because Windows 10 64-bit includes WOW64 (Windows 32-bit on Windows 64-bit), a compatibility layer that allows legacy 32-bit applications to run seamlessly on a 64-bit processor without any additional configuration or emulation software. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of Windows architecture and application support on mobile devices like tablets; a common trap is assuming you need to enable compatibility mode or install a virtual machine, but the correct answer is simply to run the installer as usual. Remember, when you need to run a 32-bit app on a 64-bit Windows 10 tablet, WOW64 has your back—think “WOW, it just works.”
220-1101 Mobile Device Application Support Practice Question
This 220-1201 practice question tests your understanding of mobile device application support. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 setting up a Windows 10 tablet for a field worker who needs to use a legacy line-of-business (LOB) app that only runs in 32-bit mode. The tablet has a 64-bit processor and Windows 10 Pro. How should the technician ensure the app runs correctly?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Install the app normally; 32-bit apps are supported on 64-bit Windows.
This question tests knowledge of Windows compatibility and application support on mobile devices. Windows 10 64-bit includes WOW64 (Windows 32-bit on Windows 64-bit) by default, allowing 32-bit apps to run without additional configuration. No special steps are needed.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Install the app in a virtual machine running 32-bit Windows.
Why it's wrong here
This is overly complex and unnecessary; 32-bit apps run natively on 64-bit Windows via WOW64.
✗
Enable Windows 8 compatibility mode for the app.
Why it's wrong here
Compatibility mode is for older OS versions, not for architecture differences; the app will run without it.
✓
Install the app normally; 32-bit apps are supported on 64-bit Windows.
Why this is correct
Windows 64-bit includes WOW64, which emulates a 32-bit environment, allowing the app to install and run without issues.
Related concept
Static NAT maps one inside address to one outside address.
✗
Download and install the 64-bit version of the app from the vendor.
Why it's wrong here
The scenario states the app is only available in 32-bit; a 64-bit version does not exist.
Common exam traps
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.
Trap categories for this question
Scenario analysis trap
The scenario states the app is only available in 32-bit; a 64-bit version does not exist.
Detailed technical explanation
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.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
