CompTIA Linux+ (XK0-004) — Question 282

Which of the following commands will let a Linux user know the PCI devices that are installed in the system?

Answer options

• A. cat /proc/devices/pci
• B. lspci
• C. lsdev
• D. cat /proc/sys/dev

Correct answer: B

Explanation

The correct command is 'lspci', which specifically lists all PCI devices connected to the system. The other options do not provide the relevant information about PCI devices; 'cat /proc/devices/pci' and 'cat /proc/sys/dev' are incorrect paths, and 'lsdev' is used for listing device information but not specifically for PCI devices.
