Which of the following apt-get commands will install the newest versions of all currently installed packages?
- A. install
- B. full-upgrade
- C. dist-upgrade
- D. auto-update
- E. update
Answer: B
Explanation:
Explanation
The apt-get command is used to interact with the APT package management system on Debian-based Linux distributions. The apt-get command has several subcommands that perform different operations on packages.
One of these subcommands is full-upgrade, which is used to install the newest versions of all currently installed packages, along with their dependencies. The full-upgrade command also removes any packages that are no longer needed or that conflict with the upgraded packages. The full-upgrade command is equivalent to the dist-upgrade command, which is an older name for the same operation. The other options are not valid subcommands of apt-get. The auto-update option does not exist, the install option is used to install specific packages, not to upgrade them, the update option is used to update the list of available packages, not to install them, and the dist-upgrade option is the same as the full-upgrade option.

Which of the following options is used in a GRUB Legacy configuration file to define the amount of time that the GRUB menu will be shown to the user?
- A. hidemenu
- B. timeout
- C. splash
- D. showmenu
Answer: B
Explanation:
Explanation
The timeout option in a GRUB Legacy configuration file is used to define the amount of time (in seconds) that the GRUB menu will be shown to the user before booting the default entry. The timeout option is usually located in the /boot/grub/menu.lst file. For example, timeout 10 will display the GRUB menu for 10 seconds.
To disable the timeout and wait for user input indefinitely, the value of timeout can be set to -1. To boot immediately without displaying the menu, the value of timeout can be set to 0. The other options are not valid for the GRUB Legacy configuration file. References:

NEW QUESTION # 133
Which of the following commands moves and resumes in the background the last stopped shell job?
- A. bg
- B. back
- C. run
- D. fg
Answer: A
Explanation:
Explanation
The bg command is used to move and resume in the background the last stopped shell job. A stopped job is a process that has been suspended by using Ctrl+Z or the kill -STOP command. The bg command will resume the execution of the stopped job and allow it to run in the background, without blocking the current shell. The bg command can also take a job number as an argument, which can be obtained by using the jobs command.
For example, if the last stopped job is 1+ Stopped sleep 500, then the following command will move and resume it in the background:
bg %1
The output will be:
1+ sleep 500 &
The fg command is used to move and resume in the foreground the last stopped or backgrounded job. The run and back commands are not valid commands in Linux. References:
