LX0-103 · Question #90
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 the PCI bus and reports detailed hardware information about connected PCI devices, but is limited to PCI-related data.

Why each option
The lspci command queries the PCI bus and reports detailed hardware information about connected PCI devices, but is limited to PCI-related data.
lspci can display IRQ settings and other resource assignments for PCI devices when using verbose flags such as -v or -vv, showing the interrupt lines allocated to each device.
lspci reports PCI bus topology and speed information, including bus numbers and link speeds for PCIe devices when verbose output is requested.
lspci only reports on PCI-connected hardware; battery type is an ACPI/platform attribute reported by tools like upower or acpi, not lspci.
lspci always displays the vendor ID and device ID for each PCI device, resolved to human-readable names using the PCI ID database at /usr/share/hwdata/pci.ids.
Ethernet MAC addresses are Layer 2 identifiers stored in the NIC firmware and reported by ip link or ifconfig, not by lspci which operates at the bus/device level.
