CHAPTER 1. Flashcards
Why should you install the server with a GUI installation pattern?
a. To prepare for RHCSA, you need some tools that run in a GUI only.
b. The minimal installation is incomplete.
c. If you do not install a GUI immediately, it is hard to add it later.
d. The Server with GUI is the default installation that is recommended by Red Hat.
A.
In particular, when working with virtual machines, you’ll be happy to
have a GUI at your disposal.
You want to install a test environment to practice for the RHCSA exam.
Which of the following distributions should you avoid?
a. The most recent Fedora version
b. CentOS 8
c. Scientific Linux 8
d. RHEL 8
A.
Fedora is an experimental/enthusiast version containing many components
that may or may not make it into the RHEL distribution tree and
onto the RHCSA exam.
Which of the following features is available in both RHEL and CentOS?
a. Hardware certification
b. Software certification
c. The right to make support calls

D.
All RHEL software updates are made available in CentOS as well.
Which is the default file system that is used in RHEL 8?
a. Ext3
b. Ext4
c. XFS
d. Btrfs
C.
XFS is used as the default file system. When Red Hat decided
which file system to use as the default file system, Btrfs was not stable
enough yet.
Which feature is supported in Ext4 but not in XFS?
a. The ability to shrink the file system
b. Snapshots
c. File system quota
d. A maximum size that goes beyond 2 TB
A.
The size of an XFS file system cannot be reduced.
Which of the following is not a reason why Fedora should be avoided?
a. Fedora contains features that may or may not be available in future RHEL releases.
b. Fedora distributions show a much later state of development than RHEL.
c. Fedora software is not stable.
d. Software in Fedora may differ from the same software in RHEL.
C.
The Fedora project tries to make a stable distribution as well.
There are many Fedora users around the globe who use it as a production distribution.
Which of the following options is not available from the Installation Summary screen?
a. Time & Date
b. Keyboard
c. Language Support
d. Troubleshoot an Existing Installation
D.
The Troubleshoot an Existing Installation option is available when booting from disk, not on the Installation Summary screen.
After setting the root password that you want to use, you cannot proceed in the installation. What is the most likely reason?
a. The password is unsecure, and unsecure passwords are not accepted.
b. The password does not meet requirements in the password policy.
c. You also need to create a user.
d. If an unsecure password is used, you need to click Done twice.
D.
You are allowed to use an unsecure password; you just have to confirm
it twice.
Which statement about the system language is not true?
a. You can change the system language from the Installation Summary screen.
b. You can change the system language directly after booting from the installation media.
c. When setting the installation language, you can also select a keyboard layout.
d. After installation, you cannot change the language settings.
D.
Language settings can be changed after installation.
This is done easily through the Settings option in the graphical interface.

Even if it makes sense having /var on a dedicated partition, this is not part of a default installation.
What is distribution?
RHEL 8, CentOS (etc) is a Linux distribution.
What is KDUMP?
Allows you to use a KDUMP kernel. This is a kernel that creates a core dump if anything goes wrong.
What is Fedora?
Fedora, a completely open source Linux distribution that is available for free. Red Hat has a lot of staff dedicated to contributing to the Fedora project, because Red Hat uses Fedora as the development platform for RHEL. The result is that Fedora offers access to the latest and greatest software, which in most cases is much more recent than the thoroughly tested software components of RHEL (which is why you should
not use Fedora to prepare for the RHCSA exam). Fedora is also used by Red Hat as a testing ground for new features that might or might not be included in future RHEL releases. If you were to choose Fedora, you would be working with items that are not available in RHEL, which means that you would have to do things differently on the exam. So, don’t use it!
You do not want to buy an RHEL license, but you want to create an environment to practice for the exam. Which distribution should you use?
CeontOS
You want to install a minimal system. How much RAM do you need?
1 Gig of RAM
