Q

What is involved in the installation step, starting the install?

A
  • 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:

Q

What is the best choice when setting the system time for networks that are dispersed over multiple time zones?

A

For networks dispersed over multiple time zones, choosing UTC simplifies administration tasks. (Some distributions have options to synchronize the time over the network.)

Q

What is a disk partition?

A

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:

Q

What are the typical partitioning options provided during installation?

A
  • 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.

Q

What is a swap partition and what size should it be?

A

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.

18
Q

How many partitions can you create on each disk?

A

Linux computers can only have four partitions, but a single extended partition can be sub-divided into additional partitions.

19
Q

Which directories should have separate partitions, and what are the advantages of doing this?

A

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.
20
Q

What comprises applications and services?

A
  • 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.
21
Q

What are the minimum length and complexity guidelines for secure passwords?

A
  • 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).
22
Q

What purpose does the host name and domain name serve?

A

The name of the computer identifies the computer on a network.

23
Q

What does enabling and configuring network logons do?

A

Network login options enable the system to access a server for login information rather than maintaining local authentication information.

24
Q

What additional resources might be required when configuring hardware settings?

A

Hardware configuration settings might require appropriate drivers or language settings.
