In Depth Look At Red Hat Certification 163
The following was written by Slashdot Reader Matthew Miller
I'm fortunate enough to work at a place that realizes the importance of keeping employees educated and up-to-date. Since my largest current project is Linux-related, and based on Red Hat's distribution in specific, we thought it'd be worthwhile to send me to Red Hat for their RH300 course. I'm pretty familiar with Linux, but I'm a long way from knowing everything, and it's always interesting to learn what the vendor thinks are the most important parts of their product. We chose RH300 because it's the highest-level systems administration class currently offered. It's also the one linked to the RHCE exam, which was an added bonus, but learning was my main goal, not getting the certification. This is my report on the experience -- hopefully, it will help you decide if this is a good choice for you, either as a sysadmin or as an employer.
The Training Center
This course is not only available directly from Red Hat, but also from various partner organizations, including Global Knowledge, which has a training center here in Boston. However, we decided that if we were going to go to the expense of sending me, I might as well go directly to Red Hat, to increase the chances of getting a good instructor, and to insure adequate access to resources. We've had experiences in the past with third-party instructors who didn't know much beyond what was written in the materials. Of course, I don't know that this would be the case with Global Knowledge's version of RH300 -- perhaps someone else can comment on any experience they've had there.
So, it was off to the Red Hat headquarters in Durham, NC. Incidentally, I stayed in the Residence Inn there -- it was on Red Hat's site as being nearby. They didn't mention that it was on the other side of a major highway, with no provision for pedestrians to get across. Moral: stay at one of the closer hotels, or else get a car. Anyway, the RH building is very nice -- much bigger than I expected. (I suppose the IPO cash is going to good use.) Of course, as students, we weren't shown much of it -- no tour, and we weren't introduced to any of the celebrity employees. (Fair enough -- with several classes coming through every week, they'd never get anything done.) The people I did meet seemed pretty cool, and in general I got the impression that it's a fun place to work.
The classroom was about as I expected -- projection screen up front, rows of decent-enough small-brand Celeron-based systems (one per student). The machines were on a private network -- reasonable for the course, but unfortunately there was no provision for Internet access, which at the least would have been nice to have when I finished labs early.
We did have access to a breakroom with free soft drinks / juice and various snack items. This is also where the lunches were served -- to my surprise, these were quite good, and there were even decent non-meat choices.
The Teacher
The instructor was very knowledgeable -- not necessarily a complete guru, but he knew his stuff, including the "why" behind the course material. He was able to present the material in a good way, and was good at answering questions. I think the decision to go to Red Hat directly was wise; unlike a third-party consultant, he had some idea of what was going on inside of Red Hat and of their potential future plans. For example, during the section on the printing subsystem, he mentioned that they're considering a replacement for LPR in future releases -- perhaps LPRng or even CUPS. It's unlikely that someone from a different company would have had access to that kind of information.
Other Students
The other students in the course had a wide range of skills and backgrounds. I think that everyone probably met the listed better than pico. However, I could tell that some people were struggling. The instructor mentioned that the pass rate for the exam is about 65%, and I wouldn't be surprised if our class came out at that level or worse. It's not that anyone was stupid -- just that some people were out of their depth. On the other end of the spectrum, there were some people who were over-qualified: a few highly experienced sysadmins, and some folks from IBM taking the class because they are soon going to teach it.
The Course
The course was generally similar to the outline found on Red Hat's site, although I think the online information is a bit out of date. (Notice that the Web page makes reference to ipfwadm instead of ipchains or netfilter.) The eight units had slightly different names, and covered slightly different information. In the most drastic example, Unit 8, listed on the Web site as "Systems Administration and Security II", has turned into "Routers, Firewalls, Clusters and Troubleshooting". Some of the information listed in the online Unit 8 was moved into Unit 7, and some of it (cops, for instance) wasn't talked about at all. Hopefully, the online info will be updated soon.
Overall, the class went into less depth than I was hoping. Some of this was due to limitations of the lab setup -- it's a bit difficult to experiment with RAID in any meaningful way when you've only got one IDE hard drive, and obviously impossible to set up a cluster on one machine (short of running VMware). Other things where just plain introductory -- the section on the kernel, for example, focused on the steps required to build and install a new kernel, rather than being an in-depth discussion of tunable parameters. The part about Apache was similar; I was hoping to hear "You've all configured Apache before; here's things you should be aware of when you need it to do such-and-such", but the most advanced we got was setting up a virtual host. Building RPMs from source was mentioned briefly, but there was no information given on important and largely undocumented topics like --buildpolicy.
That's not to say I didn't learn anything -- the section on LVS / Piranha was enlightening even without hands-on experience, and I appreciated the part about quotas, which isn't something I've worked with much. And, I learned a large number of tiny things which add up to making the experience worthwhile to me. RPM can now do globbing over ftp! Portmap uses tcp_wrappers, but doesn't do reverse name lookups, so be sure to use IP addresses instead of names. RH Linux provides a little script called "service" that lets one avoid the tedium of typing /etc/rc.d/init.d/servicename all the time. And so on....
The "300" designation is a bit misleading. This isn't really what I'd consider an upper-level course -- it's more along the lines of SysAdmin 101. Overall, I think this class is probably worthwhile to someone with a good RH Linux background who hasn't done any systems administration. In fact, I'd even recommend it to people in that situation. On the other hand, if you've been a Linux sysadmin for a while, you'll probably be bored most of the time. It might be valuable to experienced Unix sysadmins who haven't dealt with Linux much (or even Linux admins who haven't used Red Hat Linux), but the course wasn't particularly taught from that angle and there are probably better options.
The Exam
Since I signed a confidentiality agreement, I can't talk about specific details of the test, but I will address the exam in general terms. It's a day-long three part process, with each part being worth 1/3 of the total. To pass, your overall score must be at least 80%, and you can't do worse than 50% on any one part.
One of the sections is a typical multiple-choice test, but the other two are lab based. I was quite impressed with the hands-on tests -- they are certainly what makes the RHCE meaningful. I'm not aware of any other sysadmin certifications that work this way.
For one of the lab tests, students are given a several-page specification, and must install and configure Red Hat Linux and several network services. This wasn't particularly difficult, and shouldn't be for anyone with much experience. For me, the hardest part was resisting the temptation to go beyond the spec -- since I finished the given requirements with plenty of spare time, I considered installing and setting up additional services in a way that would fit in with the listed goals. But, I decided that it'd be better to leave well-enough alone -- there's no concept of extra credit.
The other hands-on test is the cool and exciting one. Students are given preconfigured setups which are broken in some way, and given a task that must be completed. The system's problem doesn't necessarily relate directly to the task, but does interfere with it. The test-taker must find out what's wrong and correct the error. (Reinstalling packages is not allowed.) Being able to list the steps taken and to repeat the fix is important, but ultimately the test is scored on a works / doesn't work basis. One the examiner verifies that the problem is fixed, he or she wipes the system and provides another broken config.
This problem-solving section directly tests skills important to being a sysadmin in the real world; if someone has trouble with these, they're probably not ready for a systems administration job. Of course, just passing this test doesn't guarantee good problem solving skills (let alone all the other needed abilities), but it does seem a genuinely valuable indicator.
I've only two complaints with this part of the test. First, I'd make it a much larger section -- at least 50% -- and I'd increase the number of problems given so that there'd be a better sample size. The various challenges are assigned at random, and some are easier than others, and each tests knowledge of different parts of the system. The way it's done isn't bad, but it wouldn't hurt to have a lot more of it. Second, I'd give each student two computers, and make more of the problems network-related. This has logistical and cost issues (especially in places other than Red Hat's own training centers), but since many of the problems faced in the real world have to do with the way systems interact, I feel it'd be worth it.
The Exam Separated From The Course
You may have noticed that I seem a lot more excited by the exam than by the course itself. I think both are valuable, but they seemed aimed at slightly different levels. The course definitely can serve as a good review for the exam, but if you need the course, you won't do well on the test. If you're tight on cash and the certification seems valuable to you or to your employer, going straight to the exam would be reasonable. (Make sure you take a look at Red Hat's test prep page.) On the other hand, if you need to be quickly brought up to speed on the basic knowledge required of a RH Linux sysadmin, it might make sense to take this course without worrying about the test. Since RH300 is equivalent to RH033 + RH133 + RH253, this could be a much more intensive and time-efficient option.
Red Hat-Specificness
It's probably obvious, but bears mentioning anyway: this is a Red Hat Linux course and certification, not a general Linux one. I found this to be true both explicitly and implicitly. The instructor was good about saying "This is the Red Hat way of doing things -- it's possibly different on other distributions." (I found the increase-the-whole-pie attitude to be common to all of the RH employees I talked to.) There were also quite a few things that were just assumed. If you take the exam without knowing a lot about Red Hat Linux in particular, you're likely to have trouble.
This doesn't make the certification meaningless for organizations running other distributions -- many of the skills and knowledge required for the test (especially the problem solving part) are generally applicable anywhere. In fact, due to the lab-based testing process, I have more respect for this exam than I might for a multiple-choice test covering more distributions. I think this issue is a one-way sort of thing: the RHCE exam requires knowledge of Red Hat Linux, but anyone who can pass it shouldn't have much trouble picking up other flavors.
Stuff
Ok, the Web page promises that they'll give Red Hat promotional items to course participants. Yeah, well, they can do better on this front. Not even a t-shirt! C'mon, everyone gives t-shirts. Vendor shirts are a staple of my wardrobe! All we got was a mousepad, some stickers, and a baseball cap. (No chance of getting a red fedora.) Oh, and of course an official copy of the CD (with the 180 days of support). Many people in the class were surprised to learn that Red Hat doesn't sell anything from their offices -- you can't buy copies of the distro or additional merchandise. They've got a lot of students coming through there, so it seems like this could be a decent (even if relatively small) revenue stream.
A Bit About Study Guides
Before I went, I flipped through RHCE Exam Cram , the sole study guide I found at the local bookstore. Someone in the class actually purchased it and brought it with them, and I got a chance to read more of it then. I wasn't really impressed. The book was especially concerned with what it called "trick questions", and indeed its sample questions were sometimes a bit confusing -- and often poorly worded. After taking the test, I can say that this seems mostly to be a problem with the book, not something encountered on the actual exam, which was mostly straightforward and fair.
There are RHCE study guides, but I wouldn't recommend spending any money on any of them. As the course instructor told us: if you're going to pass, you'll do so even if you don't have a guide. And if you're going to fail, the guide won't be much help.
Conclusion
I think the RH300 course and RHCE certification can be valuable to both employers and individuals. The course provides a nice quick overview of the basics needed to move, for example, from being a systems operator to being an admin. I wouldn't think of it as either a requirement for the test or as something that can make someone not ready suddenly have the skills required for the exam. Since the exam is hands-on and lab based, those abilities can only come from real world experience. Looking at that from the other direction: this is exactly what makes the RHCE worth anything. While it's not a total statement on someone's talent, being able to pass is a strong indicator that they have the basic skills for a systems administration job. If I were making hiring decisions, I wouldn't make the RHCE a requirement, but I would have more confidence in applicants who have it.

When I returned to work, I informed my boss to never send ANYONE to Global Knowledge again if possible. For the money, conditions should have been better. My instructor answered questions wrong sometimes. I jumped in and corrected him. He didn't have anyone to refer to if he had a stumper, unlike an instructor at RedHat.

This lack of certification opportunity for the general public (you can get Apple certified at Apple Service Centers, but not on your own hook) is (partially) responsible for holding the Mac back: IT and corporate managers, who are considering switching to the Mac platform, look around for techs that will support them through and after the change, and can't find anything definitive.

I'm not sure what you mean when you say "The other thing I didn't agree with is the RedHat Specificness."
Here's some things that are Red Hat specific that we talked about without particularly pointing out non-RH ways of doing things: the install program (including kickstart), chkconfig (and sysv init scripts in general), PAM, sndconfig, kudzu, piranha. The instructor didn't make a point of saying that these things may be different elsewhere, but he did clearly say "This is the way it is on RH Linux." That's what I mean by it being implicitly Red Hat-specific. There wasn't a particular effort to demonstrate other ways of doing things, but there was definitely the understanding that those might exist.
There was no attempt to make it seem like Red Hat is the only way.
There were also things that were overtly mentioned as being the Red Hat way of doing things -- for example, the user-group scheme they use. For a different class, I wouldn't be at all surprised if the times where the RH-ness is mentioned were different -- it was mostly assumed as understood.

While I believe that the marketing effect of having "vendor certificates" for a product is positive (both for the holder of the certificate and for the product), there is more to the story than just that. I would like to point out two issues in the following:
Without disqualifying any certificates in particular, then there is imho a fundamental problem with such "vendor certificates" - and that is just that: they're "vendor". Most of the certification programs I've had contact with emphasize "the way of the vendor" a lot, and ignores (or assumes known) the general workings og things.
Let me give an example, which unfortunately is not just "thought up": most OS vendor certificates teach "setting up networking" and such. Some even "debugging network problems". Yet none (of those I have seen or heard of) set asside sufficient time to teach the fundamental understanding of the protocols behavior and how to utilize and interpret the output of various tools (traceroute and tcpdump comes to mind). I support this observation by experiences from working in a large organization with various OS-vendor certified personel (Novell and MS-certifications) - to whom the notion of "port numbers" under IP was completely unfamiliar (yes, the MS person in question did have the MS networking part, or so his resume said). I do believe that he could set up MS-something-server much faster than most (as could the Novel guy probably with a Novell-product), but that was not the issue (which was figuring out why some traffic didn't get through a particular router).
This leads me to the other issue, namely that with all those "vendor certificates", HR-people tend to hire more on those (the flash-value of a bunch of golden-framed certificates is known to be high in HR), than on the actual skills. The result (as was my experience) was, that the IT-department ends up with lots of people, who can (rightfully) claim to be "certified" - but who cannot really claim the understanding of what is going on...and who definitely will work less-than-good in a heterogenous setting (as most places really are: different servers, mainframes, terminals and workstations in a mess of a network with a mess of different traffic).
Anyways, the emphasis on "vendor certificates" has - in my experience - caused people to focus on "getting the certificate" (because that catches the eye of the HR-people) rather than on the actual learning the skills. And that is the real problem: very few do as the author of this very fine review of RedHat's certification process and say "hey, I know most of this stuff in general, but now I really need to know how RedHat do things". Most rather think "Uhmm...Redhat == money, I need that certificate".
Finally, a problem about vendor certificates is, that there is no real control with what they yield. Traditionally, teaching organizations (one way or another) are subject to some level of control, which should guarantee some level of quality. As the author of the review rightfully points out, then there might be big differences between what the course looks like in different sites. (not that the courses in universities and colleages do not differ either, but they are supposibly subject to some sort of quality control...)
That said, I find it encouraging that RedHat does provide what (to me) seems like rather real settings for part of their tests: "This machine is broken, fix it!" and "This machine should do XXX, make it so". I hope and wish that the training behind does provide a good background for doing this propperly.
Yet I still believe (and am trying to teach HR) that it is more important to evaluate actual skills and experience than simply to count the number of certificates....

You could stay a generalist but until you become a big-time system consultant or project manager it does not pay to be a generalist in the computer business.
So how do you show that you have enough knowledge despite the fact you job is not solely focused on the skill. You get the certification. I am going for the Solaris certification. It is not the basis of my resume but it highlights the fact that I take what I want to specialize in seriously.

An interesting thing to me about the RHCE program is that for it to be worth much, it must (as Matt says it successfully does) distance itself from the idea that only Red Hat's Linux is Linux.
While someone could also (copyright quibbles aside) start an alternative certification program to the MSCE, it'd be hard to imagine that it could ever be as well accepted or prestigious, simply because only one vendor controls the spec. "If you're going to ask someone, you ask that guy over there, he buil the thing."
On the other hand, while Red Hat may be a big name and has grabbed attention / brand recognition, would anyone frown on a "Mandrake Certified" engineer, or someone who's "SuSE Qualified"? (Or whatever
After all, the same kind of flexibility which makes so many distributions of Linux possible and worthwhile would also be good in the realm of certification -- the more robust the market the more worthwhile such things will be. And (this is backhanded logic maybe but it's my only weapon) perhaps a diversity of all-equally valid certification programs will reduce the percieved need for / dominance of both any particular one and in fact such certifications in general. If they're going to exist (they do, and they will), they should at least be seen as "a feather in your cap" rather than the whole suit and shoes.
Since the common perception seems to be that such certs are basically formalities for those willing to obtain them, wouldn't want interviews with otherwise qualified job candidates, say, to hit a hiccup when the interviewer says "Hmm. I see you're not Red Hat certified. I guess you can leave your resume with the desk and we'll be in touch
ok, a ramble. But the more administratively / philisophically spread out and the less offically important such certs are, the better in my view.

I had a gentleman at redhat named Randy Russel who knew his stuff...at least a good bit more than me. Even better...he knew how to teach. The course was good..although I didn't learn a ton. but without the course as a review of everything I am not sure I would have done as well on the test. And their helpful hints on troubleshooting were excellent...and things I necessarily haven't done in depth.
The other thing I didn't agree with is the RedHat Specificness. Although it was obviously a bit specific...my instructor pointed out the "other" traditional ways to do it...and many times stated a preference to editing files rather than gui tools. the only real redhat specific thing they did was there was no telling you how to build non-rpms....but hey...you have to expect some redhat specificity.
I do agree with this as well. DO NOT BUY THE STUDY GUIDE IF YOU ARE TAKING THE COURSE. There is no need. They are dumb.
The cert ws worth it...it wasn't easy (for the general public) and it will weed out those who do not have linux experience...but for those of us like myself who have been using it exclusively for 2+ yrs...(myself around 6)...it was easy.

What this means is that a certification program depends more on marketing and getting PR and HR together to be successful. Competency is, unfortunately, second. As a side-effect, this means that people like me aren't going to look at it seriously until the people in a position to hire me do. This is why many people are going for their MCSEs - they know HR reads the 4 color glossies MS sends out. Of course, the tech department groaned loudly when HR went off and stuck up another job description without consulting them (HR won't get stuck with the new guy, will they?).
So, in a nutshell, RedHat should pour alittle money into PR to make sure HR knows who they are. And, the 4 color glossies never hurt.

The simple reason is that Linux isn't Windows. Credentials for Linux users in place of things like prior experience is sometimes needed. In my business, we have customers asking for Linux support for our products. Our sales people can say that there is a RHCE on staff, which is somewhat rare for the industrial PC business. Of course, most people who are asking for Linux support know that Red Hat != Linux, but the RHCE exam does ask enough general Linux questions to (IMO) make a RHCE a Linux Expert.
Everyone knows a Certified Windows person who has 0 clue about Windows and how to do proper administraton. Go find Certified Linux person (Red Hat or not) who is that clueless. It's hard. You probably won't.

I am really glad to hear about this facet. It sounds like Redhat learned something from Cisco on this one. The CCIE ( Cisco Certified Internetworking Engineer ) is one of the toughest and most respected certifications on the market.
It begins with a qualifing exam taken at normal testing centers. This exam covers every single networking protocol used in the last ten years, along with every physical connection and permutation. In the TCP section you must correctly identify, by byte range, the different parts of the TCP header.
If you manage to pass that then you must go to Cisco to do the hands on labs which are very similar to what has been described for the Redhat tests. A full day of "Set this up to do X" followed by "Why does this not work?".
No, I don't have the CCIE, but don't think I'm not working on it.

(or so I think) I mean, I'm sure working on open source projects at 13 helps you learn a lot, but there are design fundamentals and lots of underlying knowledge necessary about compilers, and assembly, and hardware, that you need to have to really understand what's going on. Hopefully, our economy will improve enough so that more people can get a quality education [washingtonpost.com]. Or, to be more acurate, hopefully our entire economic paradigm will shift [zmag.org] enough to allow everyone to get a decent education.

However, I must say I agree with those folks who speak out against vendor-specific certification. I would jump in a minute at the chance to take a general Linux certification exam. I hold two of CompTIA's general specifications (A+ and Network+), and feel that the skills reviewed in those exams are good samplings of the kind of knowledge computer professionals need to have. Not knowing where the default install location for a specific package on a specific distro is a momentary problem for anyone with a basic knowledge of UNIX/Linux. With a strong elementary knowledge base and a good skill set, learning a new distro would be a snap for someone with some experience.
I champion vendor neutral certifications for the same time I advocate Liberal Arts universities and colleges: Specific skills become obsolete quickly.
