What information can the lspci command display about the system hardware? (Choose three.)
The lspci command is used to list all PCI devices in a system and can provide several types of information about those devices. It can display device IRQ settings, which helps in determining how devices are communicating with the system’s processor. It can also show the PCI bus speed, providing insights into the data transfer capabilities and performance of the PCI bus. Additionally, it can provide device vendor identification, which includes details about the manufacturer and device model. The other options, such as system battery type and Ethernet MAC address, are not typically displayed by the lspci command.
The lspci command alone does not provide any other information but hardware vendor. To inspect further, need to run lspci twice, the 2nd run add -s flag followed by corresponding hexadecimal numbers at the beginning of line examined in 1st lspci run, and finally -v flag. Eg. lspci -s 00:03.0 -v With this run, we can get IRQ and bus information
thanks anhcq for you demonstration
This answer should be corrected to "E". It's also easy to reconstruct (check in terminal), as anhcq already explained. Even after 2 years still the wrong answer here.
