A system administrator is trying to find out what filesystems are mounted on a Linux system. Which of the following commands can be used to do this?0.5 Marksmountlsblkdffdisk -l

The command that a system administrator can use to find out what filesystems are mounted on a Linux system is the "mount" command. Here are the steps to do this:

1. Open a terminal window. This is usually done by searching for "terminal" in your system's main menu.

2. Type the command "mount" and press Enter. This command displays all the filesystems that are currently mounted on your system.

3. To make the output easier to read, you can pipe the output to the "less" command by typing "mount | less". This allows you to scroll through the output if it's too long to fit on one screen.

The other commands listed have different uses. "lsblk" lists all block devices (like your hard drives and any partitions they have), "df" reports the amount of disk space used on all mounted filesystems, and "fdisk -l" lists all partitions on all hard drives.
