as far as i am concerned you have to know very very little about the config files to pass. essentially the rhce exam is proving you can get the job done. however you want to do it, if you can make your system pass the automated tests then that's all you need. a good example of this is how often tcpwrappers comes into things. lots of the exam is about restricting access to servers from certain sources, now most server daemons can do this, but most of redhats builds are linked against tcpwrappers, so you can often accomplish the tasks without touching the service itself, just from hosts.allow and hosts.deny modifications.

Hints are available in the course outlines. For example, you're concerned about HTTP. The prep course for the RHCE is RH300. The course outline as listed at https://www.redhat.com/training/rhce...e_content.html specifies the following under HTTP

# The Apache Web Server
# Virtual Hosts
# Apache Access Configuration

In other words, know how to create virtual hosts. While not specified in the course, the public exam prep guide (https://www.redhat.com/training/rhce/examprep.html) specifies HTTP and HTTPS. So it's fair to assume that you need to know how to create HTTP and HTTPS virtual hosts during the RHCE exam.

Access configuration, you'll have to figure out for yourself but if you can figure out virtual hosts, HTTP access configuration is not hard.

Why not take both the RH253 and RH300 classes? If you are sure of yourself when it comes to the RHCT classes, then these last two should prepare you well for the exam. I would NOT recommend walking in off the street to take the RHCE exam. I took both the RH253 and RH300 and needed both. Of course I am no Linux guru either. I do know I could NOT have passed without taking the RH253. The RH300 was a VERY welcome refresher and confidence booster prior to the exam. Besides, no matter how much you know there is always something new.

Good Luck

Thanks for your replies.
I know the couorse outline of RH253. The thing is that there are so many things to cover in server part. I know how to configure DNS or apache in no time but the thing is I find more details on configuring servers rather than in RH253 book. Thats why I m asking should I use that book as a reference?
notiones, I agree with you in no matter how much you know there is always something new. But let me first pass the exam then I will go for something extra.

You keep mentioning the RH253 book. To which book do you refer?

You probably already know we cannot discuss the exam, but I can tell you that my advice was based upon what I cannot say.

I can say that no publicly published book that I found can adequately prepare you for the RHCE exam unless you consider The RHCE Study Guide by Michael Jang, which came came pretty close. If you can do everything in that book you should be fine.

Best of luck.

once again i'll raise my hand and say that Jang's book is more than adequate for rhce.

Yes, for RHCE the book provided by redhat is nice but with out professional guidence you might loose a lot of money as becz the exam fees is not less. Almost about $749 in USA.
