You will learn nmcli and nmtui, dig, host, and nslookup, systemctl and journalctl, timedatectl and chronyd, and cron and systemd timers through detailed walk throughs. You will also see tools for checking connectivity and diagnosing service failures.

This course builds skills for roles like Linux Administrator, Network Administrator, DevOps Engineer, and Site Reliability Engineer:the kind of roles where keeping systems connected, running, and automated is part of the job. 

If you've completed Linux Foundations and Linux Administration Essentials, this course adds networking, service management, and automation skills to your RHCSA preparation, but it's one part of the path, not the whole thing. It's designed to be taken as part of the RHCSA Certification Preparation Specialization, where you'll progressively build the full set of skills required for the EX200 exam.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
