Full question →hardmultiple choiceObjective-mapped
A technician is troubleshooting a Windows 10 workstation that crashes with a blue screen error 0x0000009F (DRIVER_POWER_STATE_FAILURE) every time the computer is put to sleep. The technician has updated all power-related drivers, disabled sleep in power options, and run SFC and DISM without finding issues. The crash still occurs when the user manually selects 'Sleep' from the Start menu. 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
A hardware device has a firmware bug that fails during power state transitions
Correct. A faulty firmware in a device (e.g., USB hub, network card) can cause a power state failure even when drivers appear updated. Replacing the device or installing a firmware update can resolve the issue.
B
Distractor review
The Windows installation is corrupted beyond repair by standard tools
SFC and DISM are designed to repair corruption. Since they passed, a full corruption is unlikely. The issue is likely hardware or firmware related.
C
Distractor review
A third-party service configured to run during sleep is causing the crash
Services are paused during sleep; a crash at the moment of transition is more typical of a driver or firmware failure than a service.
D
Distractor review
The computer is infected with a rootkit that interferes with power management
Rootkits can cause stability issues, but the specific, consistent trigger of sleep mode and the failure of malware scans make this less likely than a hardware firmware issue.
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: A hardware device has a firmware bug that fails during power state transitions — The DRIVER_POWER_STATE_FAILURE bug check indicates a driver that does not handle power state transitions correctly. Since standard driver updates and software fixes did not resolve the issue, the problem likely originates from a low-level device such as a USB hub or network adapter that has a firmware bug or incompatibility with the system's power management. Replacing such hardware is the next logical step. Reinstalling Windows would be excessive, and checking for malware is less likely given the specific trigger.
