Which TWO commands can be used to display the current kernel version on a Linux system?
⚠ Common exam trap
CompTIA often tests the distinction between commands that display kernel version (`uname -r`, `/proc/version`) versus commands that show kernel module information (`lsmod`, `modinfo`) or boot logs (`dmesg`), leading candidates to confuse related but incorrect options.

Correct answer & explanation
✓
uname -r
The `uname -r` command displays the kernel release version, which is the standard way to quickly check the current kernel version. The `cat /proc/version` command reads the /proc/version file, which contains a string that includes the kernel version, compiler information, and build date, making it another reliable method to view the kernel version.
