What might you have to do to ensure that the system will boot from the correct installation media?
You may have to configure the BIOS to boot from the correct installation media.
Under what conditions should you select the UTC for the system time?
You should select UTC for the system time when you have networks dispersed over multiple time zones to simplify administration tasks.
How can you create more than four partitions on a Linux system?
You can create more than four partitions on a Linux system by making one of the four primary partitions an extended partition, which can be sub-divided into additional partitions.
What are the characteristics of a secure password?
A secure password includes at least 8 characters, uses numbers and symbols in addition to letters, and is not based on a username or a dictionary word (or common variations).
What is the purpose of the bootloader?
The bootloader determines which operating system boots by default if more than one operating system exists on a computer.
What are the general steps necessasry to install a Linux operating system?
- Start the install
- Select a language
- Set the system time
- Format partitions
- Select applications and services
- Set the root password
- Specify a host name
- Configure network connections
- Configure services
- Add new users and groups
- Configure the hardware settings
What is involved in the installation step, starting the install?
- Configuring the BIOS to boot from the installation media (if necessary)
- Booting the computer from the installation media
In many cases, this step involves booting the computer from installation media. The BIOS may need configuration to boot from the media. Linux installers often offer different installation options, such as:
What are some common installation options offered by Linux installers?
- New install
- Reinstall
- Upgrade
- Installation recovery
- Reduced feature installation
What are the implications of the language you select at installation?
The selected language becomes the default language for all users; however, it can be changed later, if necessary.
What are the two options when setting the system time at installation?
The system time can be set to local time or Coordinated Universal Time (UTC) time.
What is the best choice when setting the system time for networks that are dispersed over multiple time zones?
For networks dispersed over multiple time zones, choosing UTC simplifies administration tasks. (Some distributions have options to synchronize the time over the network.)
What is a disk partition?
A partition is a logical division of a storage device associated with a hard disk drive. This may require initializing a hard drive. Partitioning options can include:
What determines your directory structure, partition structure, and file system types during installation?
Determine the directory structure, partition structure, and file system type for each partition according to the specifications in your installation plan.
What are the typical partitioning options provided during installation?
- Use all space - makes a single partition from the entire disk drive.
- Replace existing Linux system(s) - re-partitions all the previously installed Linux Operating systems.
- Shrink partitions - reduces the size of an existing partition making room for additional partitions.
- Use free space - creates a partition from unpartitioned space on the disk drive.
- Create custom layout - manually creates partitions according to the specific needs of the system or administrator.
What does initializing a hard drive do?
Initializing a hard drive removes all existing data.
What is a swap partition and what size should it be?
A swap partition is required for virtual memory. Swap partitions should be between one to two times as large and the amount of RAM on the computer.
How many partitions can you create on each disk?
Linux computers can only have four partitions, but a single extended partition can be sub-divided into additional partitions.
Which directories should have separate partitions, and what are the advantages of doing this?
The following directories should have separate partitions:
- /home (user directories)
- /opt (installed software)
- /var (log files)
Advantages: - Keeps logs, user files, and application installations from consuming all disk space and crashing the system.
- Makes recovery easier if the operating system crashes: the operating system can be reinstalled on the root partition, then other partitions can be re-mounted with no data loss.
What comprises applications and services?
- The boot loader determines which operating system boots by default if more than one operating system exists on a computer.
- Package patterns include packages necessary for specific computer roles, such as Graphical Desktops or Web Servers.
- Package repositories are locations on the Internet where software packages are maintained. Specific Linux utilities search and install software automatically from these package repositories.
What are the minimum length and complexity guidelines for secure passwords?
- Include 8 characters or longer (longer passwords are harder to crack).
- Include the use of numbers and symbols in addition to letters.
- Do not include a username or a dictionary word (or common variations).
What purpose does the host name and domain name serve?
The name of the computer identifies the computer on a network.
What does enabling and configuring network logons do?
Network login options enable the system to access a server for login information rather than maintaining local authentication information.
What additional resources might be required when configuring hardware settings?
Hardware configuration settings might require appropriate drivers or language settings.
