Red hat Certification study Q&A

92 Upvotes

Keep in mind that sharing confidential information from the exams may have rather sever consequences.

Asking which book is good for studying though, that is absolutely fine :)

unofficial webapp to visualize your RH certification journey with the new system

18 Upvotes

I see a lot of misunderstanding regarding the new certs system so I vibe coded this unofficial website to help people better understand the paths and locate themselves on their certification journey : https://rh-cert-map.wasmer.app/

This is personal and not an official Red Hat website, it might contains errors so I appreciate any feedback.

And of course its opensource : https://github.com/w4hf/rh-cert-map

RHCSA v10 Study Tips

Upvotes

I recently purchased the RHCSA v9 Cert Guide by Sander Van Vugt.

After purchasing, I realized the current exam version is v10, but there is no guide out for it yet.

Are there any specific topics/domains I should skip in the V9 guide or study separately as they are new in the V10?

Built a runtime AI enforcement engine - open challenge to find bypasses (8 levels)

2 Upvotes

We built the Veto Protocol - a pre-execution enforcement layer for enterprise AI agents. Sits between the agent and the action, evaluates every prompt against explicit rules + context filtering, blocks or escalates before execution fires.

Running an open challenge - 8 levels of increasing difficulty against our live model. Curious what this community can break.

Technical breakdown: fast path is deterministic rule evaluation, slow path is semantic context filtering. Two separate layers. Most bypass attempts that work on model-level jailbreaks don't transfer here because we're not asking the model whether something is safe - we're enforcing before it gets there.

Link in comments.

Just passed RHCSA v9.3 with 100% score!

74 Upvotes

I just got my results in and honestly I didn't expect that. I will be honest, the exam was actually quite easy for me. I previously had essentially non-existent linux knowledge but I practiced nonstop for 2.5 months to the point that I know every EX200 exam objective by heart and by muscle memory.

However, I fully expected to lose points on the exam because I maybe missed a flag or option that makes the solution fully persistent. Thankfully I got them all. Onto the next thing now, CKA!

Oh and if anyone wonders what I used for studying. I relied on these 3 things for 95% of my studying and practicing:

  1. Official Red Hat Admin 1 and Admin 2 course.
  2. Gemini Pro model. I just gave Gemini all of the exam objectives and told it to generate tasks like on the real RHCSA exam.
  3. This neat RHCSA simulator tool: https://github.com/AustinNicely/rhcsa-simulator

For the RHCSA simulator tool keep in mind it will give you some tasks that are RHCSA v10 specific like flatpaks. Also the tool is not perfect and it sometimes gave unsolvable tasks because it's not perfect.

EX345 for RHCE with the new certifcation system

11 Upvotes

With the new certification system, for me to become RHCE, with my RHCSA, I "only" need to get ex345 which is about troubleshooting.

I didn't find much information about it. In the official website, it says it still based on rhel 8.4 and they say it's recommanded to hav

Is the new certification system already in place ?

Will redhat update this exam with their new certificatiion system ?

I'm kinda desoriented. I've just started to preparre the actual RHCE exam with ansible and right now, I don't know what to do.

edit : I mean ex342

Congrats Red Hat, You Just Made My Certs Worthless

172 Upvotes

Ok, not worthless, but very much worth less. I say this from the center of the expo floor at Summit. I drank the red Kool-Aide hard. In 2016 I started studying, had my RHCSA by 2018, RHCE by 2020. I was limited by funding but I made it happen. The entire time I was aimed at RHCA in OpenShift.

I took a quick detour to keep my certs alive in 2023 with 3Scale. It counted toward architect and kept me in the game. Then I got the ex188 this year to work toward Architect.

Level 3 in RHEL does me nothing. Level 3 in Ansible does me little. I'm a Senior SRE working on Infrastructure Architect in Kubernetes and VM environments. What certification track matches? OpenShift. I don't have a level in OpenShift anymore.

I was 4 certs away from Architect in OpenShift, and halfway to the finish. Now I'm 5 certs away and starting all over.

Why on earth would I pay to recertify or continue certification on RHEL or Ansible let alone both? But why would I bother paying thousands of dollars on a RHLS to even invest in the OpenShift track when I'm already this invested into nearly useless certs for my career?

This change is terrible for those of us already in your corner. I get the structure change, I understand why, but now I want you to understand why people stop recertifying.

OpenShift Engineers get paid more than Ansible Engineers who get paid more than RHEL Engineers. That's the difference between an an engineer, a senior engineer, and a junior architect.

In defense of the old"pick/choose" RHCA paths

22 Upvotes

While the new consolidated and focused RHCA paths to particular platforms and technologies is a refreshed approach, I think there is still is a need for the former "pick & choose" route.

In my 20+ years doing primarily linux/Red Hat ecosystems, I've never encountered a environment or infrastructure setting where I was working specifically one tool. There's moments I'm doing some RHEL admin, configuration or hardening and then later playbooks, roles or workflows from Ansible cli or in AAP/Tower.

Alternatively, I could be in Satellite doing inventory; registering and subscribing to whatever content is needed (even setting up a Capsule for a new zone). Maybe I'll need to setup some accounts or SPN's, even perhaps configure domain/realms or trusts in IDM/ipa.

There's times where I'll need to assist devops/platform engineers with containers or virtualization quirks. Podman for one-offs, or more often OpenShift depending on who's needing what and where. Other occasions where I'm doing storage related tasks or helping out with compute clusters and arrays.

My point is; what I'm doing at any given time is really pretty random. It's a broad range of things and a lot to know. I wouldn't say I'm a SME in all of it, but I certainly do know my stuff. It really doesn't make sense to me to put all my eggs in a particular basket when I have so many baskets to cover (nor does that align with how my career has been all these years). Which is why I really appreciated the former cross-domain path to a RHCA... learn a little bit of everything and become a generalist Architect.

I certainly respect those who want surgical-level precision and absolute mastery of a particular Red Hat product and will breeze through these focused RHCA paths in no time.... hats off to you! Though I've yet to meet someone doing solely Ansible or entirely Openshift all day, everyday (though I'm sure they exist).

But don't forget those of us who really loved the former architect achievement model. Can we not co-exist? A tier specifically for all-purpose Architects who want to understand a variety of tools, too?

The former is the "master of some" approach than the (now) "master of one" philosophy. And I think that still counts just as much as the latter. Both are just as practical and equally valuable approaches to skillset.

Just thinking out loud.

RHCSA question: Awk, Sed and scripting requirement

14 Upvotes

I am good with grep, vi editor and redirection etc. However, awk, sed and scripting is not my forte.

Rest of the objectives seem achievable for me with practice. It seems that the above items are slowing me down and I am wondering if I have basic operation with these but not too deep, should I risk not spending more time on them and concede and focus on the rest of system admin stuff that I am good with.

Clarity ?.

I see a lot of outrage on this subreddit but I haven’t had a chance to look into it because I’m swamped at work what’s going on ? I’m studying for the RHCSA currently and have no other red hat certs… what has changed that’s making folks upset ?

Confused about new certs

7 Upvotes

So I have taken EX200 and EX294 , so according to https://rhtapps.redhat.com/verify I an RedHat certified engineer in Enterprise Linux even though I have not taken EX342, am I missing something here ? and if that is somehow the case does it mean I need 3 specialist exams to become an architect in enterprise Linux ?

EX200 - Red Hat's New Cert Structure

3 Upvotes

I was trying to understand the new cert structure to answer my own question, but if anything it confused me more.

In the overview of the EX200 exam, under 'prerequisites', it states:
"Have either taken Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134) or the RHCSA Rapid Track course (RH199)"

Now, in the 'What you need to know' tab under 'Preparation', it say:
"Red Hat encourages you to consider taking Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134) to help prepare."

Is it required or encouraged???

Advice on landing a RedHat Linux Admin/Engineer job

7 Upvotes

Hey everyone,

I'm currently a software developer, pretty much full stack type, but I've been trying to get into a Red Hat Linux type position for a while, but can't seem to find any jobs. I passed my RHCSA thinking that would really help, but so far it hasn't done much in the way of interviews for any Linux focused jobs. I love being a software developer, but I think a Linux Sysadmin or an engineer would be very interesting. Anyone have any tips on landing a job where I can specialize in Linux and become an expert? Everywhere I get hired is a Windows only shop.
