Debugging

During installation, you need to ensure there is plenty of hard disk space allocated to the partition that will hold the entire Linux operating system. Which of the following is the BEST mount point for this partition?

/

You are installing Linux on an old computer with an old BIOS and planning the partitions for the hard disk drive. Which of the following directories SHOULD exist in the first 1,024 cylinders of the hard disk drive?

/boot

Which of the following directories MUST remain on the same partition? (Select three.)

Which of the following directories MUST be part of the partition that holds the root (/) directory? (Select three.)

/etc /bin /proc

What is the full path to the directory that contains user data for all standard users on the system?

/home

You are in the process of manually creating the partitions during a Linux installation. Knowing that users will often require a lot of space to store their files, which of the following directories (or mount points) SHOULD be configured on its own partition?

/home

If not cleared out, log files can eventually consume a large amount of data, sometimes filling a drive to its capacity. If the log files are on the same partition as the operating system, this could potentially bring down a Linux computer. Which of the following directories (or mount points) SHOULD be configured on its own partition to prevent this from happening?

/var

For which of the following directories should you create separate partitions? (Select two.)

/var /home

Most Linux distributions propose that you create the root (/) and swap partitions by default. To prevent user files and system log files from filling up the / partition, which additional partitions are you MOST strongly advised to create? (Select two.)

/var /home

What is the correct order for the boot phases of a Linux computer?

1st) BIOS 2nd) Bootloader 3rd) OS Kernel 4th) systemd or init

You have a Linux system with 8 GB of RAM installed. You plan to use this system as a server. How much space should you plan to partition for the swap file?

8 GB

Which of the following are considerations you should review when selecting the file system you want to install with your Linux installation? (Select two.)

Encryption support Recovery support and speed

Which of the following are basic steps commonly performed during a Linux installation? (Select two.)

Format the partitions. Specify a hostname

Which of the following boot methods provides higher performance (larger files and greater distances than TFTP) and is often used to replace the PXE boot method of network deployment?

HTTP

Which of the following is a file image containing an exact copy of a Linux installation disc?

ISO

The LC_ALL and LC_TIME configuration variables on your Linux system have no values (null) associated with them. However, your system is set to use a 24-hour clock. From the drop-down list below, select the environment variable that is configured to use a 24-hour clock on your system.

LANG

You are trying to pipe data from the cat command to another program, but the data output does not make sense. You believe that the system's locale is corrupting the output. To test your hypothesis, you decide to change a locale environment variable. Which of the following changed variables would MOST likely produce correct data?

LANG=C

Which environment variable overrides all other locale settings and sets all locales to the same setting?

LC_ALL

Which of the following is the last step the OS kernel performs during a UEFI boot on a Linux machine?

Loads and executes either the init (Initial) process (for older distributions) or the systemd process (for newer distributions).

What component is responsible for loading and executing the initial process?

OS kernel

You have a Linux server where the bootloader is malfunctioning and can no longer boot. You want to re-install a new copy of Linux over the network using the firmware on the server's network card, and should be as simple to use as possible. Which of the following boot methods will BEST meet your re-installation needs?

PXE

You want to perform a Linux installation using the network installation method. You have already prepared the network and are ready to prepare the clients for the installation. Instead of using a CD, DVD, or USB media with an ISO image, you want the client computers to download the software required to gain access to the server containing the Linux distribution installation software. Which of the following technologies can you use to perform this type of installation?

PXE

Which of the following is the first step in planning and designing an effective Linux installation?

Perform a needs assessment

Which of the following is network information you should gather before installing a Linux distribution? (Select two.)

Server information for DNS servers Subnet mask

Match the locale environmental variable name on the left with the correct description on the right.

Specifies personal name format. LC_NAME Specifically used an override for LC_MESSAGES. LANGUAGE A special variable for overriding every other environment setting. It sets all locales to the same setting. LC_ALL Defines every locale setting at once while allowing further individual customization via the LC_* settings. LANG

Which of the following are requirements for a PXE boot to work on your Linux client computer?

The client BIOS/UEFI must be configured to use PXE. The NIC in the client computer must support PXE boot.

Which of the following has a process ID (PID) of 1?

The initial process

You have a system with more than one Linux operating system installed. During the system's bootup process, which component loads a splash screen, allowing you to choose which operating system you want to run?

The secondary bootloader

Which of the following character sets is a variable length encoding standard of Unicode that uses one to four 8-bit bytes to support many languages and is most commonly used on Linux?

UTF-8

During the bootloader phase of the UEFI boot process, an optional initial RAM disk image called initramfs is loaded into memory. Which of the following BEST describes the initramfs image? (Select two.)

Used to mount the file system and load the kernel into RAM. A custom version of the init program containing all the drivers and tools needed at boot.

Which of the following is true about the ASCII character set? (Select two.)

Uses a seven-bit encoding technique. Does not include international symbols.
