Disk Druid is made by Red Hat and used in its distribution along with some derivatives. Partition Magic and System Commander are tools made by third-party companies. Answer d is not a tool, but a file system type. Specifically, FAT32 is the file system type used in Windows 98.
Question 7
You have a new application on a CD-ROM that you wish to install. What should your first step be?
Read the installation instructions on the CD-ROM.
Use the mount command to mount your CD-ROM as read-write.
Use the umount command to access your CD-ROM.
Use the mount command to mount your CD-ROM as read-only.
Question 8
Which of the following tasks is not necessary when creating a new user by editing the /etc/passwd file?
Use the passwd command to assign a password to the account.
Add the user to the specified group.
Create a link from the user's home directory to the shell the user will use.
Create the user's home directory
Question 8 Explanation:There is no need to link the user's home directory to the shell command. Rather, the specified shell must be present on your system.
Question 9
You want to enter a series of commands from the command-line. What would be the quickest way to do this?
Put them in a script and execute the script
Separate each command with a / and press enter after the last command
Separate each command with a semi-colon (;) and press enter after the last command
Press enter after entering each command and its arguments
Question 9 Explanation:The semi-colon may be used to tell the shell that you are entering multiple commands that should be executed serially. If these were commands that you would frequently want to run, then a script might be more efficient. However, to run these commands only once, enter the commands directly at the command line.
Question 10
Which of the following commands will show a list of the files in your home directory including hidden files and the contents of all sub directories?
ls -l /home/username
ls -aR /home/username
ls -c home
ls -aF /home/username
Question 10 Explanation:The ls command is used to display a listing of files. The -a option will cause hidden files to be displayed as well. The -R option causes ls to recurse down the directory tree. All of this starts at your home directory.
