$1$

Switch to the graphical terminal $($tty$1)$ by pressing Ctrl$+$Alt$+$F$1$ and log in to the GNOME desktop using your user account and the password of LINUXrocks!.

$2$

In your virtualization software, attach the ISO image for Fedora Linux to the virtual DVD drive for the virtual machine. After you have completed this action, view your Files application. Is there an icon that represents your Fedora Live installation media in the left pane? Place your mouse over this icon to view the mount point directory. Which directory was your ISO image automatically mounted to$?$ Take a few moments to explore the contents of the ISO image within the Files application. When finished, close the Files application.

$3$

Switch to a command$-$line terminal $($tty$5)$ by pressing Ctrl$+$Alt$+$F$5.$ Log in to the terminal using the user name of root and the password of LINUXrocks!.

$4$

At the command prompt, type du $-$hT and press Enter. Is your ISO image still mounted? What filesystem type is used? What device file is used? Next, type ls $-$l $/$dev$/$cdrom and press Enter. Is $/$dev$/$cdrom a symbolic link to this device file?

$5$

At the command prompt, type umount $/$dev$/$cdrom and press Enter to unmount your Fedora DVD$.$ Next, type du $-$hT and press Enter to verify that it is no longer mounted.

$6$

At the command prompt, type cp $/$etc$/$hosts $/$mnt and press Enter. Next, type ls $/$mnt and press Enter to verify that the $/$etc$/$hosts file was successfully copied to the $/$mnt directory.

$7$

At the command prompt, type mount $/$dev$/$cdrom $/$mnt and press Enter. What warning did you receive? Next, type du $-$hT and press Enter to verify that your ISO image is mounted to the $/$mnt directory.
