M-keyed M.2 slots provide up to four PCIe lanes for maximum SSD performance. B, A, and E keys support fewer PCIe lanes or different I/O interfaces.
A tenth-generation Intel desktop CPU uses which socket type?
LGA1200
LGA1151
AM4
TR4
Intel's tenth-generation desktop processors use the LGA1200 socket. LGA1151 was used by earlier generations, and AM4/TR4 are AMD sockets.
In a RAID 5 array with three drives, what happens if one drive fails?
The array operates in degraded mode with data still accessible.
The array becomes read-only and data is lost.
The array rebuilds automatically without redundancy loss.
All data is immediately lost.
RAID 5 uses block-level striping with distributed parity, so if one drive fails, the array operates in degraded mode and data remains accessible. Only when additional drives fail before a rebuild does data loss occur.
When diagnosing electromagnetic interference affecting system stability, which tool can visualize signal waveforms over time?
Oscilloscope
Multimeter
Thermal camera
POST diagnostic card
An oscilloscope visualizes electrical signal waveforms over time, making it ideal for diagnosing EMI and signal integrity issues. A multimeter measures steady-state voltage/current but cannot display high-frequency variations.
