I've been trying to find the following information on the RHCSA website but I cannot find it listed -- only on blogs posted about these exams so I wanted to confirm the information that I am getting is correct:

1. Are they any prerequisites to sitting this exam?
2. Can you sit this exam at a testing centre or do you need to take the offical training? 

As I have access to other training materials I was looking at saving costs, rather than buying the offical training materials.

Kind regards,

I literally have a Xeon Server with 32 gig of ram. I was thinking of the following.

Centos 7 on host machine
KVM running two instances of centos

One of the machines would have additional space to practice partitions etc.

How do I get the machines to communicate with each other? Do I have to assign a I.P for each machine? Or can I bridge or use NAT.

How did you set up lab? I need some inspiration.]]>

I didn't know where to post it, so I post it here. Perhaps it might be useful to someone that is about to purchase a Red Hat training or exam.

I have a 15% discount code (UK only) valid for up to three trainings/exams which I am selling on Ebay.

The code is valid till Sat, 29 September 2018. That doesn't mean you will have to take the exam/training by then. ***You only need to complete the purchase by that date*** - the training/exam can take place at any date in the future.

Reasonable offers welcome - if I don't sell it - I will use it myself.

I have a few exams left to reach my RHCA - Cloud and I was looking for something that I can do with taking the Red Hat class and doing just a little bit of studying.

I'm thinking of taking the EX280 or EX236 currently, but there are others as well I may end up doing.

I'm curious how people that have taken multiple exams would rate them in difficulty (no NDA related info needed). Just curious if some on my list are closer to torture, or a stroll through the park :D]]>
RHCSA and RHCE what video course and book? https://community.infosecinstitute.com/discussion/133395/rhcsa-and-rhce-what-video-course-and-book Tue, 21 Aug 2018 14:58:32 +0000 LPI, Red Hat & Linux Foundation andrew_69 133395@/discussions
New here. I have decided I want to study for both these exams with a plan to try and sit the RHCSA some time in December 2018.

My first question is what video series to buy?

I am torn between Sander Van Vugt's videos:

RHCSA

RHCE

and the Linux Academy's Videos:

RHCSA

RHCE

The thing that strikes me as a big difference between the courses is the amount of hours each one is. Sander's course is 28hrs total whilst the Linux Academy is 70hrs in total.

I noticed on another thread dude indicated he actually did both Sander's and the Linux Academy videos.

Does seem like over kill tho and would also take a long time to go through all that.

From people that have passed the exams is it necessary to do both video series or is it sufficient to just do one?

As for the book I was thinking of buying Sanders premium edition book as study material:

Red Hat RHCSA/RHCE 7 Cert Guide Premium Edition and Practice Tests | Pearson IT Certification

What do people think?

Video series and book and lots of practice sufficient? I am in a full time Linux role currently but only 1.5years experience.]]>
Studying LPIC1 and LPIC2 before RHCSA? Is it waste of time? https://community.infosecinstitute.com/discussion/130982/studying-lpic1-and-lpic2-before-rhcsa-is-it-waste-of-time Mon, 29 Jan 2018 18:56:03 +0000 LPI, Red Hat & Linux Foundation zodiark 130982@/discussions
I just finished studying Linux Essentials and I'm in the process of polishing my basic Linux skills.

On my path to RHCSA certification, what I actually set on my study time line are: Linux Essentials > LPIC1 > RHCSA then probably get my certification by next year.

While browsing some forums, I found out that some suggestion says skip the LPIC series and go directly to RHCSA. Some other says Linux Essentials then LPIC1 and LPIC2 then RHCSA.

Is it worth it to add LPIC2 from my original study time line?

What are your thoughts about it?

Thanks!]]>
Failed RHCSA Monday https://community.infosecinstitute.com/discussion/131288/failed-rhcsa-monday Thu, 22 Feb 2018 20:15:15 +0000 LPI, Red Hat & Linux Foundation josephandre 131288@/discussions


There's been some challenges going between the three in that Linux Academy for how great it is, the servers leave something to be desired outside of some basic administration. Then Sander and Cert Depot, go back and forth between RHEL 6 and 7 managing to confuse the ever living **** out of me on certain objectives.


I still felt confident, have been labbing my brains out, felt like i knew most everything inside and out, and the remaining things competently enough to make it through.

So I took the exam, I felt pretty confident all the way through, but I botched something that ultimately earned me a zero.

had to remove some of the details, as despite trying to be vague, I don't want to violate my nda.

PS, passed today.]]>

RHCSA minor panic! Machine fails to boot. https://community.infosecinstitute.com/discussion/133128/rhcsa-minor-panic-machine-fails-to-boot Fri, 27 Jul 2018 10:24:58 +0000 LPI, Red Hat & Linux Foundation max_lan 133128@/discussions Screen went blank and stayed blank. Waited a bit longer, still blank. Not even a grub prompt or bios messages or ....
Minor panic : 15 minutes is probably not enough time to reset to nothing and get it all working again enough to pass.
Power off the VM, wait a moment and power on : it works. Phew. Start breathing.
A couple more reboots and it always reboots fine.

So, I'm chalking it up to "one of those things" but then I got scared because I've heard that unbootable instances score zero. What if it fails to boot when they try to mark it??

Anybody had a similar experience? Will they "try again" if the boot fails?

NB I was chuffed when I realised I did my RHCSA on Sysadmin day. Lets just hope I scored well!]]>

What I'd like to find out from you guys is how you started off in Linux, with the RHCSA but overall in general. At the moment I've set up a RedHat environment at home and just playing around with it really. I've got a command **** sheet from a few years back and going to look at tasks to do online.

How long did it take you to train for and pass the RHCSA? What resources did you use? I plan on doing my RHCE after so I plan on really investing on some hard study material and will probably keep practicing each day for a good 6 months before I even consider taking the exam.

Also, would you suggest it's worth spending time learning some scripting languages in the meantime like Python or Powershell? Should I also look at doing some SQL work on purely just focus on Linux for now? Any help is much appreciated.]]>
Questions regarding LPIC-2 https://community.infosecinstitute.com/discussion/125192/questions-regarding-lpic-2 Mon, 13 Feb 2017 05:30:12 +0000 LPI, Red Hat & Linux Foundation linuxc128 125192@/discussions
I recently passed the LPIC-1 (CompTIA Linux+ Powered by LPI). Although I took classes for preparing the exam, in fact I studied all the required knowledge by myself - I should add that I'm 31-years-old now and working with/learning about Linux since I was 14, so probably I'm already in the posession of a considerable amount of knowledge about Linux (administration).

Now I plan to take the LPIC-2 exam without taking any preparation classes (I've always been good at studying things autodidactically) soon. My (first) basic questions in this regard are:

1) I have the impression that the main focus of LPI exams is on Debian (including init- and SysV-based versions), at least in case of the LPIC-1 exam (despite their claim to consider various distributions equally). Would others agree to this? And may this be (significantly) different for the LPIC-2 exam?
I think that this question is quite important, since one would need a lot of more time if trying to memorize all kind of e. g. RedHat/CentOS special characteristics.

2) Many of the exam's objectives/questions - including the information one can find in many LPIC preparation books - refer to out-dated information (e. g. GRUB/GRUB2 configuration to mention just one of many examples - some things related to X11 would be an even better example). But I guess nonetheless one should study this information, even if it's not relevant anymore or wouldn't work on a modern Linux system, right?


Kind regards and thanks in advance]]>
Back on the cert train... RHCSA > RHCE Plan https://community.infosecinstitute.com/discussion/129788/back-on-the-cert-train-rhcsa-rhce-plan Sat, 28 Oct 2017 17:12:06 +0000 LPI, Red Hat & Linux Foundation Daniel333 129788@/discussions
Starting a thread for accountability for my RedHat Certs. I am dreaming that I want to get to Redhat Architect level. So the first step is bothering to get my RHCE then start in on the specializations. I had attempted RHCE under redhat 6 a few years ago, but was disappointed when I failed and never returned to the cert.


Experience
8+ Years of Linux with various levels of shell scripting
5+ Years Puppet
5+ Years jboss
5+ Years on OS hardening
10+ Years in charge of provisioning and patching
1+ Year in Containerized environments


Existing Related Certifications
Linux+
LPIC-1
RHCSA 6.x


Existing Formal Training
Classes on managing Linux for PCI
Various SANS Courses in Hardening/Attacking Linux
RHCSA+RHCE Redhat 5x Bootcamp
RHCSA Redhat 6.x Bootcamp
RHCSA+RHCE Redhat 7 bootcamp



My battle plan is a to complete the training for LFCE on pluralsight.com, and LPIC-2 passively as a review cover any gaps or commands or options that I've forgotten over the years. Then use "Red Hat Certified Engineer (RHCE) Complete Video Course with Virtual Machines" series on Safaribooks.com for formal test prep. As always labs lab labs along the way.]]>

2> I really liked the RHA course materials and labs I used when I took RHA classes back in RHEL5 timeframe.]]>

Hiddenknight's RHCE Expedition https://community.infosecinstitute.com/discussion/123825/hiddenknights-rhce-expedition Fri, 02 Dec 2016 22:18:05 +0000 LPI, Red Hat & Linux Foundation hiddenknight821 123825@/discussions
On my machine, I'd temporarily change the boot order to LAN to pick up the boot image from the PXE server I set up on my Raspberry Pi a while ago. Before I can even walk away, I'd have to manually select the correct boot option I made as the default one doesn't use kickstart file. Then the kickstart file does the rest of the dirty work for me. I had to add the %pre kickstart script to clear away and create new partitions. Instead of having a local SFTP server to house my scripts, I used a private git repository hosted on bitbucket. The %post script would download all the necessary files in a directory. I'd have the main script run at the next reboot after Anaconda to complete the remaining configurations as I couldn't do everything in Anaconda's chroot.

Nevertheless, it was an interesting experience to take on. My scripts still have a lot of kinks that I need to iron out as I left out few comments and many error-handling. The scripts also need some refactoring as I was in a hurry, didn't bother making loops for duplicate lines with only one argument difference. Although, I did make my scripts more verbose by enabling debugging and redirect STDERR with STDOUT stream into a file. Adding $(date) was a lifesaver too. The script was nothing sophisticated than it should've been as I didn't use the double brackets in the 'if' statements consistently, and I have not use function once. I plan to hack the scripts again once I polish up my bash skill. At least I somewhat satisfied my first RHCE objective: Use shell scripting to automate system maintenance tasks.

Lately, I'm convinced I'm still missing something from my study as I feel the resources aren't enough to prepare me for the real world, let alone the RHCE exam. I've been contemplating, taking on iConrad linux lab challenge to prove my worth. If I do decide to go down this route, then I'd have to figure out how to do both in parallel and use newer software since his instruction was based on RHEL 6 and Spacewalk.]]>

The inputs shared here about the exam have been helpful in preparing me for it and having an idea on what to expect. Still, I've felt like the exam was very time intensive, there were a lot of tasks, almost each with several sub-tasks to complete in 2 hours.

I've tested against the 2016 objectives: https://training.linuxfoundation.orghttp://www.techexams.net/images/pdfs/LFCS_Domains_Competencies_V2.16.pdf but these will be modified starting from 20th March. It seemed to me that a lot of the material in the objectives wasn't represented in the exam as I expected it, while other topics which I didn't focus on so much appeared in the questions.

Like others, I've experienced the terminal lag and also a freeze of a couple of minutes, but thankfully I've been able to successfully complete it nonetheless.

I advise on mastering more subjects than are covered in the objectives, and also paying attention to command line operations with regex, some bash scripting and be able to perform a lot of disk operations. CertDepot is a good resource for practice, it's geared more towards RHCSA but also it has been very helpful for my LFCS studies.]]>

My LFCS experience https://community.infosecinstitute.com/discussion/130877/my-lfcs-experience Sun, 21 Jan 2018 21:09:42 +0000 LPI, Red Hat & Linux Foundation zlykot 130877@/discussions
I figured I would share my experience regarding the LFCS. I did my MCSE a few months back and noticed that I could easily get MCSA Linux on azure by passing this certification and so on BF I purchased the training/exam deal for $199.

I went through the official material provided by LF in about a week. I found the material selection was good but I did not particularly enjoy the format. Each chapter started with a short video, followed by a series of slides. The information in the slides was fairly straight and to the point but only covered the basics. The initial ~10 labs were quite interesting with custom snippets of code that aimed at showcasing items such as the OOM killer and various schedulers. After that things fell off a bit, the material became a lot more RH/Centos focused, labs needed a bit more work to get working on ubuntu etc.

Overall my preference would be to either have a book to read with the supplemental labs or just have it all videos.

On to the test, The process was quite streamlined from scheduling to the actual test, everything was perfect. The test itself was a bit frustrating. Terminal emulation was quite annoying, Vi for example required scrolling and I could not easily find the cursor and other things like that. I eventually gave up and just used nano ;l

The other minor annoyance was that some of the questions seemed to be in the wrong order, question 2 referenced requirements from question 5... not a big deal just not perfect. In addition one question referenced to a container as a virtual machine so finding took a few extra minutes...

Overall very minor things but the exam requires good time management, I ended up running out of time on the last question but still got a 86%. In my opinion the exam would be quite enjoyable if it allowed for the use of standard terminal/client and reworded the questions a bit.

Hope this helps someone.
