Hi!How to prepare for RHCA please tell me anyone
 

Hi!
Plz let me know how to prepare for red hat architect exam,how many subject include ,what they list ?How long to take for study ?I am already done rhce

please read the background at http://redhat.com/certification but these aren't the right kind of questions to be asking for such a high level exam. You need to KNOW what you're doing. It's not about just studying new material for the sake of it. You don't even seem aware that there IS no RHCA exam in itself, so some actual research seems the obvious thing here.

thanks for your advise Mr.Chris
 

I am already done in rhce ,although this one is very difficult I want to take exam just for voip

Again, there IS no exam. And of the areas covered in the numerous exams that can be used to equate to an RHCA, there is no VOIP as RedHat are not a VOIP vendor. Why would you want to do a certification with no background understanding of what it is?

I want to make for Data Center ,in Data Center they are more demand it.Example,storage device installation,server installation and also for security reason.

OK, good for you. Are we done here or is there something you wish to know what redhat's stie doesn't cover?

RHCA's do not work in data centers. They work in the offices making designs and writing policies. If you have an RHCA and you're installing RedHat from a DVD as your day job, you've going very wrong.
