220-1102 Software Troubleshooting Practice Question
A technician is supporting a warehouse desktop. The immediate goal is to repair Windows component store corruption before file integrity repair. Which tool, control, or procedure is the best fit?
⚠ Common exam trap
The trap here is that candidates often run SFC first out of habit, not realizing that DISM must precede SFC when the component store itself is corrupted, because SFC depends on a healthy store to complete its repairs.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DISM followed by SFC
DISM (Deployment Imaging Service and Management) is the correct first step because it repairs the component store (CBS) that SFC relies on to perform file integrity repairs. Running DISM with the /RestoreHealth switch fixes corruption in the Windows image itself, ensuring that SFC can then replace corrupted system files with valid copies from the store. This sequential order is essential because SFC will fail or report unfixable errors if the component store is damaged.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
DISM followed by SFC
Why this is correct
DISM followed by SFC is the correct repair sequence because it first uses the Deployment Image Servicing and Management tool with the /RestoreHealth switch to rebuild the Windows component store, which may have become corrupted. Once DISM has repaired the component store, running System File Checker (SFC /scannow) can then replace corrupted or missing system files using that healthy source. Without this two-step order, SFC might fail or repeatedly find errors because it depends on clean files from the component store.
- ✗
Event Viewer
Why it's wrong here
Event Viewer is a diagnostic tool that records application and system logs, such as errors, warnings, and informational events, but it does not perform any repair actions itself. While it can help you identify why a system is crashing or failing, the immediate goal is to repair the warehouse desktop, not just analyze logs. Relying on Event Viewer would only give you clues; it does not restore or replace damaged operating system files.
- ✗
System Restore
Why it's wrong here
System Restore rolls back the system to a previous restore point, reverting registry settings, system files, and sometimes installed programs. However, it is not the best fit for repairing a corrupted system because it depends on the availability and integrity of restore points, and the corruption might have occurred before the most recent restore point or the restore point may also be compromised. It is a broad rollback action rather than a targeted repair of the current system file corruption.
- ✗
Local Users and Groups
Why it's wrong here
Local Users and Groups is a management console used to create and manage user accounts, assign passwords, and configure group memberships and permissions. It has no function in repairing system files, the boot configuration, or the Windows component store. Using it would leave the underlying system corruption untouched, so it does not align with the immediate goal of repairing the desktop's operating system.
