TestOut Linux Pro Exam: Unit 1 (Linux Overview)
(Certification Practicum) Questions With Complete
Solutions
Apache OpenOffice Correct Answers A free office software
suite for word processing, spreadsheets, and presentations.
Application platform Correct Answers The operating system
provides a platform where applications can run.
Authentication server Correct Answers Most enterprise
networks require centralized user authentication and access
controls for all system resources. This is not only convenient for
users, but also allows an administrator to monitor and audit user
types and the type of access they have on each machine. It also
makes provisioning and disabling user accounts easier.
Linux centralized authentication (an authentication server) can
be accomplished in many ways, depending on the Linux
distribution being used. Some options include installing and
using OpenLDAP (Lightweight Directory Access Protocol) or
purchasing programs that aid in the installation and management
of centralized authentication, such as FreeIPA Identity & Access
Manager.
Bash shell Correct Answers provides a command line interface
Certificate Authority Correct Answers A digital certificate is an
electronic document that can be used as proof of identification.
For example, digital certificates are used between an end user
and a bank to establish a trusted connection. As an end user, we
trust digital certificates because we trust the entities that create
, the digital certificates. The entities that create these certificates
are called certificate authorities (CAs). A few of the most public
certificate authorities include GeoTrust, Comodo, Digicert,
Thawte, Verisign and GoDaddy. These CAs require the person
or company applying for a certificate (such as your bank) to
provide documents and information that proves they are who
they claim to be.
At times, you may find that using digital certificates within your
own organization can be beneficial. For example, when using
VPNs, you could use a digital certificate for authentication
instead of a pre-shared key. Digital certificates could also be
useful for such things as your development and staging systems.
Rather than paying a public certificate authority for digital
certificates for your internal needs, you can configure a Linux
system to be a certification authority. One method of doing this
is to use OpenSSL, a free open-source library.
Clustering Correct Answers With clustering, two or more
servers are grouped together in a way to make them work like
one.
Clustering is often used to create a failover system, a load
balance system, or a parallel processing unit. A failover cluster
means that if one system fails, the other servers will take over
the load, giving end-users uninterrupted access to the desired
data. There are many options for building a Linux cluster,
including using free open-source software (such as OpenHPC)
or purchasing a commercial product.
Containers Correct Answers Linux containers give you the
ability to run an application (with all of the necessary libraries,
dependencies, and files) in an isolated environment known as an
