XK0-004 · Question #42
What information can the lspci command display about the system hardware? (Choose THREE correct answers.)
The correct answer is A. Device IRQ settings B. PCI bus speed D. Device vendor identification. The lspci command queries PCI bus devices and reports hardware details including IRQ assignments, bus speed, and vendor IDs. It does not report battery or network MAC address information.

Why each option
The lspci command queries PCI bus devices and reports hardware details including IRQ assignments, bus speed, and vendor IDs. It does not report battery or network MAC address information.
lspci -v or -vv displays interrupt request (IRQ) lines assigned to each PCI device, making IRQ settings visible output.
lspci reports PCI bus topology details including bus speed and link width for each PCI slot and bridge.
Battery type is reported by ACPI tools such as acpi or upower, not by lspci, which only inspects PCI-connected hardware.
lspci always displays the vendor identification code and vendor name for every PCI device detected on the bus.
Ethernet MAC addresses are Layer 2 identifiers stored in the NIC firmware, exposed via ip link or ifconfig, not through lspci.
