My Way to Linux Certification – Tips

My Way to Linux Certification [LFCS]

Valuable Tips & Help

 

Prior Register for Linux Exam & Tips

If you are complete beginner, I recommend to read some eBooks and take some online courses to pass the beginner’s level, and after Register for exam and then take more advanced online courses/eBooks especially for the Exam.

Exam done online [From your home/office room] from Chrome browser, embedded Terminal plugin … LF [Linux Foundation] setup a remote Linux server [CentOS 7 or Open SUSE 42 or Ubuntu 16.04 choice is yours/mine]…

I preferred Register for LFCS Administrator Exam of Linux Foundation because:

You do exam from Home without need to go to Exam center, but required have your PC screen monitored and having an external camera for monitoring room, by your exam proctor …etc . Also room must be quite and you/I being alone in the room…

I you want save some money: Register week LAST FRIDAY OF JULY – this day called System Admin day and MANY OFFERS EXIST for buying exam or bundles Exam + LFS201 Essentials of System Administration course… I saved $200 by purchasing an (offer) bundle 24 July 2017… I have one year to sit in my room online the exam…. and I have got a Linux course LFS 201 in the bundle… but I recommend you find and some other eBooks and courses … this never hurts.

You have one year to give the exam. Date/Time you/I define it. If you fail first time you have a second free retry…

Before register of exam or before get training from course LFS201 Essentials of System Administration, make sure you take and finished the Free course:

LinuxFoundationX: LFS101x Introduction to Linux

https://courses.edx.org/courses/course-v1:LinuxFoundationX+LFS101x+1T2017/course/

Exam is practice/performance based. You are given a server and a list of tasks to do on it… After you graded by automated system that checks the server you practiced on… after 3 days you get the result Pass or Not. To pass you need 74% score… During exam are permitted only server itself help resources like man(manual) pages, info pages and –help pages… you can Not surf the web for help nor have notes in the desk you work in your PC… during the exam.

 

From FAQ  [extracts from LF Site]

6. How long does the exam last?

Once you launch the exam, you will have two (2) hours to complete the certification exam.

8. How can I study for Exams?

The Linux Foundation’s Certification Exams are performance-based, which means the only way to ‘study’ for them is to practice, practice, practice. The Overview of Domains and Competencies – listed in the Exam Details section of the webpage for each Certification (LFCS and LFCE) – provides guidance on the topics covered in an Exam.  Candidates are encouraged to gain as much hands-on experience as possible in order to build mastery using the command line (since the Exam terminal does not use a Graphical Interface). Be sure to check out our Free Certification Prep Guide for more help.

Scoring and Notification

A score of at least 74% must be earned to pass the Exam.

Upon completion, exams are scored automatically and a score report will be made available within three (3) business days. If a passing score is achieved and other applicable requirements for Certification have been fulfilled, a notification indicating the Candidate has been successfully Certified will follow the score report.

==================================

Linux required, as 9 from 10 servers have OS Linux… I am Mobile/Web Developer and I will give it inside one year… I will study 3h / day practicing and 2 h/day Reading/Watching Linux eBooks & courses… but without effort you cannot pass… No pain, no gain !!! This is Not my main field of work but Web/Mobile Development so I do plan to do Web and Mobile Apps all the year but I will study for Exam along…

As Freelancer I want do all alone and Not outsource server Admin works in my home office…

Note: There many organizations that offer Linux Certification… But I think LF is the best… also others may require you go in an exam center…. in your area.

 

Other Tips – https://www.linux.com/learn/tips-how-study-your-linux-certification-exam

There are different learning styles, and you’ll be more effective if you study in the way that suits you.

Taking the test immediately after the course it vital, he says. “Retention is a big factor.”

But if you’re going at it on your own, should you take the core competencies one at a time or look through them, then focus on your weakest areas? Again, that depends on your personal style.

Powers advises looking through the course material to determine whether you have the proper background. Then you can decide how to proceed.

He puts the success rate at about one in five for people who study on their own; at two or three in five for those who use online training courses that have to be completed in a set time period; and at 90 to 100 percent for structured training courses.
