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 course materials, assignments, and earn a Certificate, you'll need to purchase the Certificate experience when you enroll in a course. Eligible learners may also have the option to start with a Free Trial. Some courses may also offer a Full Course, No Certificate option. This lets you access course materials, submit required assessments, and receive a final grade, but you won't be able to earn or purchase a Certificate.

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.
