Red Hat Certification Program

Red Hat has several certifications:

• Red Hat Certified Technician (RHCT) is a two-parts test on live systems. RHCT is a three-hour hands-on exam. The exam can be taken at the end of one of the 4.5-day Red Hat classes (RH133) , or separately (RH202 RHCT Exam ).

  RHCT is an intermediate level certification

  To quote the Red Hat site:

  • "RHCT certification indicates that the person has passed a realistic performance-based lab exam that tests his/her ability to: install and configure Red Hat Linux; understand limitations of hardware; configure basic networking and file systems for a single system attached to a network; configure the X Window System; perform essential Red Hat Linux system administration; configure basic host security, set up client-side networking services required to attach to a production network, and carry out basic diagnostics and troubleshooting."

  RHCT is a subset of RHCE. it ignores such RHCE topics as network services and network security. It focuses instead on such routine systems administration topics as installation and configuration. Because this exam is a subset of RHCE, it is possible for someone taking the RHCE exam to fail part of the test, pass the part relevant to RHCT, and still be granted RHCT status. If your goal is to become an RHCE, it makes sense to first become an RHCT before undertaking the larger battery of exams.

  The RHCT exam is given on a live machine. You need to take the exam through one of the approved Red Hat testing center/course locations.
   

• Red Hat Certified Engineer (RHCE) Red Hat Certified Engineer (RHCE) is also a test on live systems. the number of topics is wider and comlexity of problems is higher too.

Level of Linux Expertise

To determine your level of experience, take our pre-assessment questionnaires or read the descriptions below for the Standard and Rapid Tracks.

Exam Preparation

The Standard Track consists of three courses -- RH033, RH133, RH253 -- and is aimed at persons who need more review of key concepts or who are new to both UNIX and Linux.

• RH033 Red Hat Linux Essentials targets IT professionals with no prior UNIX or Linux experience, and covers skills to prepare for RH133, including shell and command line essentials.
• RH131 and RH133 Red Hat System Administration are designed for those wanting to prepare for professional responsibilities as a Linux systems administrator at the Technician level. You'll learn all the skills required to manage a Linux workstation and attach it to a corporate network, including configuration of client-side network services. Prerequisites include networking fundamentals and internetworking with TCP/IP, widely available from reputable training vendors or through self-study. RH133 now includes the RHCT Exam on the last half of the last day.
• RH253 Red Hat Linux Networking and Security Administration is designed for those who desire to build skills at configuring and administering a Red Hat Linux server running key enterprise network services and security. Prerequisites include RH133 or equivalent skills.

** Rapid Track

The Rapid Track consists of one course -- RH300 Red Hat Rapid Track Course (and RHCE Exam) -- and is aimed at persons who are experienced UNIX and Linux users, networking specialists, and system administrators and need specific Red Hat Enterprise Linux training to pass the RHCE Exam (which is included).

Success Pack

Increase your chances for certification. The RHCE Success Pack acts as insurance in a way, providing a re-take of the exam for a discounted price, if you fail the first exam. Find out more.

A Look at the Red Hat RHCE Exam

by Emmett Dulaney

In the past, I've looked at Linux certification offerings from LPI, Sair, and CompTIA. This month, I'll turn to another Linux certification option: the Red Hat Certified Engineer (RHCE). Note that this certification differs from all other Linux certifications in some key ways:

1. It is not vendor-neutral as all the others mentioned are. It focuses on Red Hat's implementation of the operating system, and is kept current with the latest version (presently 7.1). Previous exams were tailored for versions 5.2, 6.0, 6.1, 6.2, and 7.0, respectively.  All who passed under those versions are still RHCEs, and there is currently no requirement to retake under the latest version.
    
2. While all other exams focus on your passing one or more computer-administered tests to become certified, that is but a small component of the RHCE certification. The multiple-choice test is one hour in length (40-50 questions), while two hands-on labs constitute five hours of exam time.
    
3. The other exams are given daily through VUE and/or Prometric testing centers (numbering in the thousands) around the world. Because of the lab component, RHCE exams are given on a scheduled basis in a few locations (currently about 20 worldwide).
    
4. With the other exams (excluding any now in beta), candidates are able to find out whether they passed as soon as they finish the exam. However, instant results are not possible with the RHCE because the lab work must be checked. All three components (two labs and one multiple-choice exam) are computed on a single pass/no-pass basis, and candidates are notified by email within 5 days. Certifications are mailed within approximately 8 weeks. To pass, an overall score of 80% or better must be achieved without scoring less than 50% in any one of the three individual components.
   
    
5. The cost of the other exams (LPI and Sair) is around $100. The cost of the RHCE exam is $749.  Many take the exam as the last day of a week-long official Red Hat prep class (Rapid Track), which costs $2,498 and includes the cost of the exam. (All prices are subject to change.)

These elements combine to make the certification one of great value, because it essentially weeds out those who are just good at guessing exam answers. Before you consider the RHCE certification, you should make certain that you are an "experienced" administrator with significant experience with all aspects of Linux. If you are not, you'll want to fill in the gaps in your knowledge before ever considering the exam.

• Review: RHCE/RH300 Training (from slashdot) by version conflict (cat /proc/kcore > /dev/audio) on Saturday April 17, @12:49PM EDT

As a person who just returned from RedHat, after completing the RHCE course, I think I have to put forth my opinion to those who are making theirs known here.  

The RHCE training course is well-designed, well-rounded and complete with a mildly-difficult lab exam. The RedHat employees are friendly and helpful, the amenities are gracious and complete. Over all, the experience was great.  

The concerns that I and others in my class had regarding course material (ambiguous questions and the occasional too easy lab) were listened to by the Training Coordinator (Peter Childers, a very intelligent and good person) personally, and all concerns were met with questions that showed intent to change the course material to the better. The course is in a state of continual improvement, and each class will be better than the last. Soon, there may be divergent levels of difficulty to accomodate the wide spectrum of Linux users. This is a good thing.  

To those who believe that the RHCE is a bad thing, take the course and decide unbiasedly. You cannot shout from the rooftops to the Linux community (slashdot) about something that you have no credible knowledge of. Go visit RedHat and talk to the people there. It will surprise you to find how much work puts into the Linux community, that is outside the scope of RedHat. They evidently have their heads screwed on straight, they are out to make a profit (what company is not?) and are doing it the right way.  

In conclusion, I recommend that people of all skill levels go and take the RHCE course. If you are a knowledgeable user, the class will teach you quite a bit. If you are a very well versed Linux developer, you might not learn quite as much, but it will be a good experience, and it will confirm your knowledge, not to mention give you "RHCE" after your name.  

History

RedHat was one of the first Linux distributors that introduced a certification program. It is oriented mainly on corporate clients and resellers. The exam for RedHat Certified Engineers is $749 --  quite expensive (more expensive than all 6 Microsoft certification exams). Tuition is even more expensive ($2500) -- it is oriented on Certified Resellers, not Certified Engineers. But on positive side probably as there will be more and more RedHat Certified Resellers, more people would trust in Linux at the enterprise environment. So even if your cannot afford it and/or your company will not pay for it, it makes sense to prepare yourself for this exam, anyway.

RH considers training as one of the most important avenues of growth (see Dan Barkin A price of going public and http://www.sec.gov). For a company that had almost no money two years ago, Red Hat has made a tremendous progress. It now has more than $10 million in cash (mostly from preferred stock sales). The IPO is expected to raise a hundred million dollars. 

And Red Hat plan to spend a lot of them for building-up of its training program. Red Hat's needs to convince investors that it has a strong business model based on impressive market share, while assuring Linux fans that it's not like "some other companies." 

Until recently the company has grown very quickly: from March 1, 1998, to the end of last month, its work force tripled (from 36 to 127). Now Red Hat is paying $900,000 a year in rent -- nearly as much as its revenue in 1996. In the fiscal year 1998, Red Hat had revenue of about $10.8 million, much of it from sales of its retail boxes. Whither this revenue stream possess big potential for growth remains to be seen, but the company clearly need a diversification and training is a perfect candidate here. 

The course includes 4 days of training and 1 day Certification Lab Exam. The course and certificate are based on Red Hat Linux 6.0.

RH recommends that all prospective RHCE participants review prerequisites in preparation for the course and exam.
