Course Description - Linux+ Specialist:
This course helps you prepare for the CompTIA Linux+
Certification exam. The course teaches Linux user commands, shell
script programming,
and essential Linux
system administration tasks. Note that completion of this course alone is
not adequate preparation to pass the exam. The actual Linux+
Certification is designed
to measure the competencies of Linux professionals who have six to twelve
months of practical experience with the Linux operating system.
Thus, after this course
you need more study, practice, and experience prior to taking the exam.
Course Benefits:
By completing the Linux + program students will have more in-depth
skills using the operating system that many security tools are
created with and
run under.
Students will leave with the latest version of Fedora Core 3 Linux, and the
knowledge to install, maintain, and use security tools associated with it.
Certified Professional Exams:
- CompTIA Linux+ Certification exam
Prerequisite:
We assume that you have used a computer before and have a basic
understanding of how to interact with one. Any previous UNIX or
Linux experience you may
have will be very helpful, whether as a user, administrator, or programmer.
