Rhel 5 & rhel 6
 

m planing to do the RHEL certification and i am not very much familer with linux platform hence kindly suggest which certification is good for me,

As you all know that RedHat has released new version RHEL6, and with it, it has also changed the syllabus as well as the Examination pattern...

If you're not familiar with Linux then no certification is good for you. Certification is designed to prove what you know, not teach you things that you don't know. You need to learn and understand Linux first, by usage, and possibly with training courses. Being certified should *NOT* be the end goal.
