Alan, I appreciate your perspective on this discussion. Like you, I'm also contributing to the question pool and working on the Anghoff studies. I believe there are pros and cons for both styles of exams. For me, personally, I prefer the hands on process, as that is where I am most challenged. Reading scenarios and choosing an answer is not something I find difficult. People are hard wired differently, that is what helps the world go around and to continue to grow as a race. Thank you for sharing your perspective and granting me the same opportunity.

Yes, I have one. I was an RHCE trainer (but not current, I have no plans to recertify for RHEL 6), and I spent 2 years full time delivering LPI-aligned training. I'm also LPI certified. I can't progress through the levels anymore, I signed that right away in return for the privilege of making large contributions to the exam question pool. I still consider it a fair trade. And I'm a senior Unix admin at a large ISP (large by local standards), and prior. So those are my credentials. I feel qualified to opine on this matter. There's nothing hard about the RHCE exam. It consists solely and exclusively of routine ordinary things that any Linux admin should be able to do blindfold. There's one section where you can include vicious gotchas and that's wrt the bootloader. I'm not giving anything anyway in that, it's covered in the course materials practicals too with stonkers like "mv /bin/bash /bin/bash.gotcha" and the old classic of setting initdefault to 6. That one is as ancient as sending mechanic apprentices to stores for a skyhook. Point being, anyone who cannot get all or most of the RHCE questions right or mostly right does not have a clue what they are doing on a Red Hat box and certainly will not be allowed anywhere near my live systems. > I am a strong proponent for tests the prove skills through active > engagement, rather than memorization and 'brain dumps'.

You appear misinformed as to what the RHCE actually tests. It can best be summed up as follows: "Demonstrated ability to perform a regular stated task in the manner prescribed to achieve a defined known result on a known defined platform." Now that's very narrow as the candidate knows for sure the test box he will be tested on is a bog-standard RHEL machine with no funnies straight off the install disk. It will have none of the stuff we have to do in real life, like build some weird package from source, bespoke stuff developed in-house, or God forbid! a proprietary DBMS. Please note that nowhere in the RHCE is the candidate's fundamental understanding of the concepts ever consulted. In fact, it is not even possible to do so, nor is it possible to normalize the results - they are too variable and not measurable. > As another person recently pointed out to me: "If you have a brain > tumor, which person do you want?

That's a false comparison and a degradation of what the LPI exam actually is. You ought to be ashamed of yourself for trying to set up that straw man, so I shall oblige by tearing it down. Like I said, I delivered LPI-aligned training for 2 years full time. How many students were able to pass any LPI exam solely using "exam cram/brain dump/study guides"? None. The ones that passed did so because they actually understood the subject matter, could think with it, and could use logical reasoning to determine sensible paths to follow. And guess what? In real life, actually on the job, what my techies deal with daily resembles an LPI exam question much more than an RHCE one. I've measured it, by actual numbers of support tickets. For every request to add a user with access right X and Y there are two tickets for some system giving errors that no-one has ever seen before. A brain surgeon has an extremely well-defined protocol he must follow in the process of dealing with a tumour. He is legally an by medical ethics required to do it that way, and doesn't get a license to practise till he has shown this. Same with aircraft pilots, deep-sea divers and bus drivers. But do note that these jobs do not test fault finding skills. And that is what *we* do all day long. So your comparison is faulty. > When it comes to on the job skills, I really don't care much about a > person's certifications, so long as the can do the job.

Certs are not a means to an end in themselves, they are merely one factor in wide array of factors, and one measurable amongst many. It is equally false to disregard exams as it is to trust them solely. All this assumes that the exam is of a reasonable quality of course. I could point you in the direction of Win2k MCSE exams for a counter-point. So in summary, the RHCE has it's place and is useful. LPI exams are useful and have their place too. The two things are diametrically opposed and not much comparable beyond both being examinations. Please don't conflate them and let's put this tired old argument to rest. -- alan dot mckinnon at gmail dot com _______________________________________________ lpi-discuss mailing list [email protected] http://list.lpi.org/cgi-bin/mailman/listinfo/lpi-discuss _______________________________________________ lpi-discuss mailing list [email protected] http://list.lpi.org/cgi-bin/mailman/listinfo/lpi-discuss
