Rhcsa - rhel6
 
Hi all,

I am planning for RHCSA Certification and have few question..

1. Can anybody tell me where I can find study material for the RHCSA certification online or can suggest me which book to be referred?

2. Can I refer "RHCE Red Hat Certified Engineer Linux Study Guide (Exam N0-201), 6th Edition (Certification Press)" by Michael Jang guide for the preparing for RHCSA exam?

Thankyou.

I would find a book with most of these objectives in it.

El6 is new, and I dont know of any books out their yet on it.

I don't know the answers to your questions, but I can give this advice.

Make sure you understand SELinux. It's set to enforcing. It's ok if you set it to permissive while you are doing one of the certification test exercises, but you must set it back to enforcing and your solution must work in that mode to get credit.

The test is timed and you have just two hours to complete it. Time can be a factor, especially if you are slow and deliberate and like to triple check your work... The test isn't terribly difficult, but getting it done in the time allotted may be a challenge for some. So, fast AND accurate is the key.

There is no Internet access during the test, so no Google. Just the documentation that is already on the system, or what you can install from their local YUM repository.

And finally when you go for the test, some good advice that I got from a Red Hat instructor. Look over all the exercises on the test and bang out the easy ones first, then concentrate on the more time consuming ones. They give you a number of exercises that are virtually "freebees" that only take a few minutes to do.

Good luck.

I am preparing for RHCE by self-learning and reading books on RHCE? Can I practice labs which are required for RHCE exam on my personal PC?
Can I use Ubuntu on my PC to practice the lab, Do i need to use Fedora?

I am preparing for RHCE by self-learning and reading books on RHCE? Can I practice labs which are required for RHCE exam on my personal PC?
Can I use Ubuntu on my PC to practice the lab, Do i need to use Fedora?

tommylovell 03-20-2011 11:08 AM

Ubuntu wouldn't be a good system to use as a learning/study tool for the RHCSA or RHCE (no LVM by default, no SELinux, Ubuntu is GRUB2 vs RHEL6 GRUB Legacy, no "system-config-*" scripts, no RPM, no YUM, and lots of other small differences). Much of what is on the test is command line oriented as many (most?) servers run at runlevel 3, not 5. And again, SELinux can be a stumbling block during the test. (I'll refrain from my anti-SELinux rant...)

CentOS 6 would be ideal but it is not out yet. That would leave Fedora 14 (RHEL6 is Fedora12 + Fedora13 + some extra stuff).

There are, to my knowledge, no practice labs available. You'd need to create your own scenarios based on the topics listed out by zer0signal and need to know that subject matter well so that you can work quickly.

Many of the topics you can do on a laptop, but for a number of them you'll need a few systems networked together. You could do that with virtualization but I'm not sure a laptop would have the horsepower. Plus you need to have a cpu that supports virtualization. Do a 'cat'/proc/cpuinfo' and look for the 'lm', 'svm' (AMD) or 'vmx' (Intel) flags. (And if you can figure out how to get virtualization working under Fedora14, let me know. I've been struggling with it for two days now...)

You are probably aware that to get an RHCE you first have to get an RHCSA. And although you can take both tests on the same day, I'd advise taking them on two separate days. 1.) you can become familiar with the test setup while taking the easier RHCSA. 2.) you'll be less fatigued taking just the RHCA by itself.

Thank you so much!! Well i will go on with my preparation with Fedora :) :)
And of course will let you know if i figure out how to get virtuailzation working under Fedora14..

can anyone help me out with rhcsa exam questions or patten .
For starters, probably no one except Tuxhub, zer0signal and I will see your post as you tacked it onto the end of Tuxhub's post. This is generally considered bad form. Start a new thread! Tuxhub, zer0signal and I get an email that this thread has been updated, but your post does not show up in "Zero reply threads" where most people look for questions that they can answer. "View latest posts" gets far less attention.

But to answer your question, there are no questions. It is a test with 16 hands on exercises. To start with, you don't have root passwords so you must break into some of the systems (that's not one of the exercises) and you need to know how to set up YUM for a local repository. After that you can choose what exercises you want to solve. The 16 exercises are worth 300 points, presumably equally valued but no one from Red Hat will confirm that; you need 210 points to pass, so 70%, or 12 correct exercises. They are computer graded. Either something works or it doesn't.

You need to know RPM, YUM, how to create an RPM package, network configuration, iptables, LVM, iSCSI, LDAP and Kerberos, KVM, GRUB, NTP setup, system logging, Apache setup, SMTP setup, DNS setup, NFS setup, CIFS setup, FTP setup, CUPS setup, SSH, VNC setup, ACLs and SELinux.

The test is timed. There is no Internet access; no cell phones; no reference material. The only documentation you have available are READMEs, info and man pages that are on the system. SELinux is in enforcing mode and everything you configure must work with it in that mode.

Good luck with your test.

I just took and passed the RHCSA this past Friday.

To prepare, I took RHA 030: Red Hat Linux Computing Essentials and RHA 130: Red Hat Linux Core System Administration at a local community college and though those classes were for the RHCT, the coursework was extremely helpful. I was able to cover the new exam objectives using material on the web. This site was particularly useful:
http://sysadkodigo.blogspot.com/p/rhcsa.html

I just started learning how to use Linux last summer, so passing this test was a big deal for me. I found time management to be the most challenging thing. You have to work at a steady pace. Man files are great to refresh your memory about syntax for a command, but if you flat out don't know how to accomplish a task you are sunk.

I wholeheartedly recommend using Red Hat's training to prepare for this exam. Check to see if there is a Red Hat Academy partner in your area:
http://www.redhat.com/solutions/education/academy/

I used Scientific Linux 6 to practice. It is a great distribution--they seem to be more on the ball than CentOS when it comes to matching Red Hat's release cycle:
http://www.scientificlinux.org/

Good luck!

Hello,

i never asked you the question , i asked u the pattern of questions which comes ( means topic ).

Hi

My statement stands!
You presented the request to the forum.
Quote:

Excerpt from LQ Rules; Do not post any messages that are obscene, vulgar, sexually-orientated, hateful, threatening, or otherwise violative of any laws.
So technically you are requesting someone to violate a LQ Rule and Laws in general. Note the above underlined text.

RH expects you to adhere to NDA. Discussion generally should not be a problem but when asking for specifics then there's the problem. Red Hat does provide objective guidelines to help prepare. Plus you can get loads of material from Red Hat or outside vendors to prepare for exams.

Look at it in another way, continuity to the Red Hat cert to keep things valid without circumventing things. There is enough material to prepare one for any cert without asking or even suggesting someone to violate a signed agreement.

Please, do not do this again!
Enough said!

BooDaddy 04-23-2011 09:59 AM

I just earned my RHCSA on March 25, and the NDA is very serious. I would not want to break it.

But, I would like to give you some suggestions that wouldnt interfere with it.

First, download yourself a copy of Scientific Linux 6 and install it....a VM (My favorite is VirtualBox) is preferable since you dont have to worry about breaking it and can just restore a snapshot if it does break.

Second, go out and purchase this book:
http://amzn.to/hws02r

Read that book. Its a GREAT resource. I took the week long training course that Redhat offers through their partners, and our instructor recommended this exact book as a great study guide and desk reference. The link I posted is the latest version that includes the new RHEL6 materials. It has great lab exercises in that really prepare you for the test....DO THEM! :)

The test itself is all lab based. And, the materials they test you may change from month to month. So you really need to be prepared for anything. The best way to prepare would be to ask yourself "what all would I need to configure and setup on a newly installed system?"
