BitLocker = full-disk encryption on Win Pro/Enterprise. Home edition doesn't have it.

Imaging 50 identical PCs = MDT/WDS/clone workflow — they want deployment tooling, not manual USB one-by-one.

IRQL_NOT_LESS_OR_EQUAL = driver or RAM issue often. Check recent driver updates first.
ipconfig /all for MAC + IP + DHCP info. ipconfig /release /renew when DHCP looks wrong.
sfc /scannow repairs Windows system files. chkdsk is filesystem/volume. Different layers.
Win11 needs GPT on UEFI systems. MBR is legacy BIOS territory for fresh installs.
TPM status: tpm.msc or Device Manager → Security devices. Win11 block message literally tells you to check TPM 2.0.

chkdsk /r schedules offline scan for bad sectors. /f fixes logical file errors.
Question catalog for this preview
Catalog listing of the 5 preview questions for this quiz.
Question 1
A technician needs to install Windows 11 Pro on a new PC. The BIOS shows the drive is initialized as MBR. Windows 11 requires which partition style?
Explanation
Windows 11 requires GPT (GUID Partition Table) for the system drive. It also requires UEFI firmware (not legacy BIOS/CSM) and TPM 2.0. MBR/legacy BIOS is used with Windows 10 and earlier. The drive must be converted to GPT before installing Windows 11.
Question 2
A technician needs to verify the integrity of Windows system files after a malware incident. Which command repairs corrupted or missing Windows system files?
Explanation
`sfc /scannow` (System File Checker) scans all protected Windows system files and replaces corrupted or missing ones with the cached versions from the Windows Component Store. `chkdsk` checks and repairs the file system/disk; `defrag` defragments HDDs.
Question 3
A Linux administrator needs to view the last 50 lines of a log file in real-time as it updates. Which command is MOST appropriate?
Explanation
`tail -f` follows a file in real-time, displaying new lines as they are appended. `-n 50` shows the last 50 lines. This combination is the standard command for monitoring log files in real-time on Linux/Unix systems.
Question 4
A Windows 10 workstation is experiencing performance issues. A technician wants to prevent unnecessary applications from loading at startup. Which tool is MOST appropriate?
Explanation
Task Manager's Startup tab (or `msconfig`'s Startup tab in older Windows) lists all startup applications with their impact rating and allows enabling/disabling them. This is the most accessible and appropriate tool for managing startup programs.
Question 5
A user deleted an important file in Windows. The Recycle Bin has been emptied. The computer has Windows 10 with File History enabled and backups to an external drive. How can the file be recovered?
Explanation
File History (enabled in Windows 10/11) continuously backs up files from the user's libraries, desktop, and contacts to an external drive or network location. Files deleted after being backed up can be restored through the "Restore personal files" option in File History.
Black screen after login but Safe Mode OK = bad startup app/driver or profile corruption — not usually HDD death.
