Which is better: Red Hat or Microsoft Server certification?

Gilbert Potter
Gilbert Potter

Windows and Linux servers are suited for (somewhat) different sets of tasks, so by choosing one or the other, you're selecting a type of working environment as well. Linux is best for public-facing stuff; Windows is best for internal-facing stuff. Windows favor a very integrated approach: Active Directory, DNS, DHCP, file sharing, and printing, Linux takes more of a "pick the tool that's right for you" approach. This means you'll be able to work with a wider variety of programming languages, web servers, database servers, etc., and that you'll get more performance out of a Linux server of the same physical specs.

Linux Foundation or LPIC? How to become a Red Hat Certified Engineer?

Isaac Griffith
Isaac Griffith

Linux Foundation or LPIC are two different organizations and so have different exams and levels. Each is distinct and hard to draw a direct parallel. LPI exams are question/answer based, but cover a very broad range of topics and require you to have a lot of knowledge memorized. Linux Foundation exams are practical and hands-on so less memorization is required, but you need to know what to do with minimal time spent on references to meet the time contstraints.To achieve the credential of Red Hat Certified Engineer, one needs to get the Red Hat Certified Engineer credential. To become a Red Hat Certified Engineer, the candidate requires to pass two certification exams, which are, Red Hat Certified System Administrator (RHCSA - EX200) and Red Hat Certified Engineer (RHCE - EX300). You will get the Red Hat Certified Engineer certification only when you have passed both the certification exams.

How long does it take to get Linux certified?

Mark Padilla

The amount of time you have to complete a task is often the amount of time the task takes to complete. If you give yourself a month to study for an exam, then that’s how much time you have, whether you’re ready or not. While most of the certifications are attainable in a span of four months, there are few which are covered in a time of 1 year. These include Certifications by Cisco.
