Full question →hardmultiple choiceObjective-mapped
A technician is troubleshooting a Windows 10 application that fails to install with error code 0x80070005. The user has local administrator rights. The technician runs Process Monitor and sees 'ACCESS DENIED' for registry key 'HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData'. What is the most likely cause?
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
Best answer
The Windows Installer service is corrupt and needs to be re-registered.
The access denied error on the Windows Installer UserData registry key indicates corruption in the MSI registration. Re-registering the Windows Installer service (msiexec /unregister followed by msiexec /regserver) often resolves this.
B
Distractor review
The user's local admin rights are being blocked by Group Policy.
Despite local admin rights, Group Policy may restrict access to certain registry keys. However, the specific key is related to Windows Installer, and the error indicates corruption, not policy.
C
Distractor review
Antivirus software is preventing the application from writing to the registry.
Antivirus can cause access denied errors, but the exact registry path points to Windows Installer internal data, which is more likely corrupted than blocked by AV.
D
Distractor review
The application installation media is damaged or incomplete.
A corrupted installation file would likely cause a different error, such as CRC failure or file not found, not an access denied error on a specific registry key.
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.

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: The Windows Installer service is corrupt and needs to be re-registered. — Error 0x80070005 is access denied. The registry key in question is part of the Windows Installer UserData, which stores installation information. This key can become corrupted or have incorrect permissions. Running the Windows Installer service with a system account reset can fix this. The issue is not about antivirus interfering, though that can cause access denied errors, but the specific registry path points to Windows Installer corruption. Re-registering the MSI service or resetting permissions on the key is a known fix.
