Essential centos 8 updates for professionals

According to students, this course provides a highly relevant and concise overview of CentOS 8's new features, making it excellent for busy professionals seeking a timely update. Learners frequently praise the clear explanations and practical examples, particularly for topics like nftables, Stratis, and VDO, which many found immediately applicable. While generally well-received, some suggest it could benefit from more practical exercises and note that it may require external documentation for deeper dives on certain topics. It assumes some prior CentOS experience, making it ideal for current administrators.

Best suited for those with existing CentOS or Linux administration experience.

"I already had some CentOS experience, which helped. Maybe a bit fast-paced for absolute beginners."

"The course serves its purpose as an introduction to CentOS 8's new features. However, it assumes a certain level of prior knowledge."

"This course is ideal if you're looking to update your existing admin skills, not if you're completely new to Linux administration."

Offers hands-on demos and practical examples for real-world application.

"I appreciated the hands-on demos which made the concepts easy to grasp."

"The instructor's explanations were clear, and the examples for Stratis and VDO were practical."

"The labs were helpful to cement concepts and allowed me to immediately apply what I learned."

A concise and highly relevant update on key CentOS 8 features.

"This course was a fantastic deep dive into CentOS 8's new features. The sections on nftables and VDO were particularly clear and incredibly helpful for my work."

"Very concise and to the point. Covered exactly what I needed to know about the transition to CentOS 8... The clarity of the content was excellent."

"Brilliant course! Very well structured and easy to follow. The topics covered are exactly what I needed to update my skills for CentOS 8."

Some learners desire more practical exercises and lab time for all topics.

"I wish there were more practical exercises to solidify understanding, especially for NFSv4.2. Overall, a solid course, but could use more lab time."

"I would have liked more hands-on labs for all topics, not just some, to reinforce the theoretical concepts."

"While the course provides good theoretical explanations, I felt a stronger need for more direct application through additional lab assignments."

Offers a good introduction but may require further study for advanced understanding.

"While the content on nftables was useful, I found myself needing to consult external documentation for deeper understanding."

"I found this course somewhat superficial. It touches on new features but doesn't go deep enough into configuration specifics."

"It's a good starting point, but not comprehensive enough for advanced users who need in-depth knowledge."
