Duration: 5 Days
With a heavy emphasis on practical, hands-on labs, content in this course is tightly aligned with experienced Linux administrators' job tasks and the skills required for advancement. Focus is placed on enhancing your automation skills to securely configure, deploy and manage network services, including DNS, Apache, SMTP, and network file sharing. In addition, you will cover security, including monitoring, packet filtering, access controls, and SELinux. At the completion of this course, students familiar with the RHCT/RHCSA administration skills will have exposure to all competencies tested by the RHCSA and RHCE exams. This class includes the RHCSA exam and the RHCE exam.
Note: Proven Impact and Red Hat do not guarantee that anyone who takes one or all of the courses in the Red Hat certification program will pass a Red Hat exam. On-the-job experience, in combination with high-quality training, is the best way to build skills and prepare for a Red Hat exam. The exam itself is a hands-on learning experience, and many of those who do not pass on the first try come away with knowledge of what they need to work on to pass the exam on a re-take.
