I plan to do RHCE certification, I have familiarity with Linux servers worked for one year. Is it advisable to install Linux (RHE 4) at home PC and learn on own and do a certification.
RHEL 4 is old - get a copy of CentOS 5.4 which is binary compatible with RHEL 5.4.
Strongly advise above method v/s attending special classes with the objective of clearing the certification exam (see Vivek Cherian's post).
There are benefits of doing a structured study course. You have to decide whether you want to learn Open Source way of working and learning or just get a certification (or any degree).
In the long run your own hands on experience will pay off much more than your 90% @ the certification exam [1].
Definitely, but sometimes a structured initiation helps.
With virtualization, you can simulate a small network on your machine and observe the behaviour of applications ...
How to virtualise, is also a big question for starters? Even how to install - and that is quite a legitimate hurdle.
At the end of the day, 90% means diddle squat when you cannot execute basic server administration; believe me your competency will be apparent within a day or two if not sooner.
are there any CBT nuggets available?
Join the CentOS/openSUSE/Debian mailing lists/forums and also go through the respective archives. Although the S/N ratio can be low sometimes, you will come across real life issues faced by admins across the world and you will definitely pick up nuggets.
The desire to learn has to stem from you. If you are the kinds who can take the risk of charting unknown territory without the risk of getting demotivated this is the best method. If you will attend the course so that the money paid for the course is not wasted and it forces you to be regular in the class - it works for me this way for my yoga class - then better join.
Besides looking @ RHCE also go through the LPI (www.lpi.org) curriculum - it is distribution agnostic and tests admin skills at the CLI level.
Do a certification only if you wish to use it as a tool to get to the interview table. do a search in Naukri and other job sites. Select the most popular one !! Else look at learning as the objective.
kindly advice
IMO, those who are really into open source solutions seldom give much credence to the certification stamps that job candidates present. I do not. I have crafted my own 45 questions quiz based on RH033 module plus basic networking fundas. Out of the ~60 candidates (some with > 80% in their cert. exam) whom I have interviewed, the best is 16 correct answers (only 2 persons). The average is a pathetic 10/45.
Arun is correct and that is my own experience as well. But by own learning as well, you miss out on certain aspects as your learning gets skewed more towards areas that you are interested in rather than an all round understanding of basic concepts. Therefore I use RHCE as a basic qualification for calling for interviews and then use my own assessment questionnaire; and the results are not too different from the above, but my experience of non-RHCE candidates is not too feasible as well because the really good ones (the self learners) are only available at prohibitive costs.
[1] I had one engineer working for me (passed a very popular Linux cert with 90%) who did not know the basics of server administration. I had asked him to complete the setup of an openLDAP server that a previous engineer had left half complete. For an entire day he kept trying to connect to the server w/o success until I asked him "have you checked if the openldap server is running?"
I am sure we all have had Engineers from good institutes in such situations as well. That does not mean the the Engineering course was ill designed - just that there was something wanting in people who imparted the course or the people who attended it.
There are no short cuts if you truly desire to be the one of the best in your chosen profession.

Therefore if you know what you want - learning or certification, the course will help if you know of the right place that imparts learning and not just training for certification.
If you just want certification - then I am not too sure whether you should look at honing your skills in the Open source Arena
