A user reports that their Windows 11 PC displays a Blue Screen of Death (BSOD) with the error code IRQL_NOT_LESS_OR_EQUAL. Which of the following is the MOST likely cause?
Faulty or incompatible device driver
IRQL_NOT_LESS_OR_EQUAL typically indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high. This is most commonly caused by faulty or incompatible device drivers.
Which of the following connector types is used with Cat 6a Ethernet cabling?
RJ45
RJ45 is the standard connector used with Cat 5e, Cat 6, and Cat 6a twisted-pair Ethernet cables. LC and SC are fiber-optic connectors, and BNC is used with coaxial cable.

In Windows 11, which command-line utility is used to check and repair the integrity of system files?
sfc /scannow
The System File Checker (sfc /scannow) scans and repairs protected Windows system files. chkdsk checks disk integrity, diskpart manages disk partitions, and defrag defragments hard drives.
A company wants to prevent unauthorized USB storage devices from being used on corporate workstations. Which of the following is the BEST approach in a Windows domain environment?
Apply a Group Policy Object (GPO) to restrict removable storage
Group Policy Objects (GPOs) allow administrators to centrally manage and restrict removable storage device access across domain-joined computers without disabling USB ports entirely, which would also block keyboards and mice.
A small business wants to use cloud-based email and productivity tools without managing any infrastructure. Which cloud service model does this describe?
Software as a Service (SaaS)
Software as a Service (SaaS) delivers fully managed applications over the internet, such as Microsoft 365 or Google Workspace. The provider manages all infrastructure, platforms, and application maintenance.
A technician is upgrading a laptop storage. The laptop has an M.2 slot that supports NVMe. Which interface protocol does NVMe use for communication with the motherboard?
PCIe
NVMe (Non-Volatile Memory Express) is a storage protocol designed specifically for flash storage that communicates over the PCIe (Peripheral Component Interconnect Express) bus, offering much higher throughput than SATA III.
A user reports that their laser printer is producing pages with vertical black lines running down the entire page. Which component is MOST likely causing this issue?
Drum unit (imaging drum)
Vertical black lines on every page from a laser printer are typically caused by a scratch or defect on the imaging drum (photoconductor). The drum transfers toner to the page, and any physical damage results in consistent vertical line artifacts.
Which Windows command-line tool allows a technician to view and manage running processes, including their Process IDs (PIDs)?
tasklist
The tasklist command displays a list of all currently running processes along with their PIDs, session names, and memory usage. ipconfig shows network configuration, netstat shows network connections, and nslookup queries DNS.
