An administrator needs to see the type of CPU that a server is running. Which of the following files contains this information?

/proc/cpuinfo is a virtual file maintained by the Linux kernel that contains detailed information about each CPU core, including model name, vendor, clock speed, and supported features. It is the standard location queried by tools like lscpu and cat, and the /proc virtual filesystem is the authoritative source for runtime hardware information on Linux systems.

/etc/devices/info.conf does not exist as a standard Linux file; the /etc directory holds system configuration files, not runtime hardware data.

/dev/proc/cpu is not a valid Linux path; /dev contains device node files and has no proc subdirectory.

/sys/dev/cpuinfo does not exist as a standard path; while the sysfs filesystem at /sys exposes some hardware info, detailed CPU data is found under /proc/cpuinfo, not /sys/dev.
