220-1102 Practice Question: A technician notices that a Windows 10 machine is…
This 220-1102 practice question tests your understanding of a technician notices that a windows 10 machine is…. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 notices that a Windows 10 machine is displaying an error message about a missing .DLL file when launching a specific application. The technician has already confirmed that the file is not in the system folder. Which built-in command should the technician use to attempt to repair the application installation?
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.
Distractor review
sfc /scannow
Incorrect. System File Checker only checks and restores protected system files, not application DLLs.
Distractor review
dism /online /cleanup-image /restorehealth
Incorrect. DISM repairs the Windows system image, not third-party application files.
Best answer
msiexec /fa
Correct. The msiexec /fa command reinstalls all components of a Windows Installer application, which can restore missing or corrupted files.
Distractor review
chkdsk /f
Incorrect. Chkdsk checks the file system for errors but does not repair application installations.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
sfc /scannow
Incorrect. System File Checker only checks and restores protected system files, not application DLLs.
- ✗
dism /online /cleanup-image /restorehealth
Incorrect. DISM repairs the Windows system image, not third-party application files.
- ✗
chkdsk /f
Incorrect. Chkdsk checks the file system for errors but does not repair application installations.
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: msiexec /fa — The Windows Installer command 'msiexec /x {product-code}' uninstalls the application, and then reinstalling it may restore the missing DLL. However, if the application is not an MSI, the technician should use the Programs and Features option to repair. The best built-in command to repair an installed application (if it supports repair) is to run msiexec with the /f option or use the Control Panel repair feature. Given the scenario, the most direct built-in command that can fix missing files for Windows Installer-based apps is 'msiexec /f {product-code}' or from command line using msiexec /fa to reinstall all components. But among options, 'sfc /scannow' checks system files, 'dism /online /cleanup-image /restorehealth' fixes system image, 'chkdsk' checks disk, and 'msiexec /x' uninstalls. The question asks 'attempt to repair the application installation' so the most appropriate is to use 'msiexec /f' or similar. Since the application is third-party, using the 'Programs and Features' repair option or running the installer again is common. However, a built-in command-line tool that can trigger a repair is 'msiexec /fa' (reinstall all). But we need to choose from typical A+ options. Often the answer is to use 'msiexec' with appropriate switches. For A+ Core 2, common knowledge: use 'msiexec /x {product-code}' to uninstall, but the question asks to repair. The best is to use the 'Programs and Features' to select Repair. But the question specifies 'built-in command'. So we'll create plausible options: correct answer: 'msiexec /f {product-code}' (or similar). Let's phrase options carefully. Rather than overcomplicate, we'll go with a more standard A+ approach: 'Use the Programs and Features applet to select the application and choose Repair'. But the question asks 'built-in command' so we need command-line. In Windows, you can run 'msiexec /fa {path-to-msi}' to reinstall all. We'll create a question: 'Which built-in command should the technician use?' Answer: 'msiexec /fa'.
