Passed EX467 today — now planning to take EX280. How difficult is it?

Hey everyone!

I passed EX467 (Managing Automation with Ansible Automation Platform) today, and honestly, I found it pretty easy.

My scores:

Manage Automation Content: 100%

Manage Access to Ansible Automation Platform: 100%

Manage Inventories and Credentials: 100%

Manage Ansible Automation Platform Projects: 100%

Manage Ansible Automation Platform Workflows: 80%

Manage Ansible Automation Platform Jobs: 73%

Interact with Ansible Automation Platform Programmatically: 100%

Maintain Ansible Automation Platform: 100%

Large-Scale Deployment of Ansible Automation Platform: 100%

I've already completed EX188 and EX200 as well.

I'm now planning to take EX280 next.

For those who have taken EX280 recently, how difficult did you find it compared to EX467? Is it relatively straightforward, or should I expect a significant jump in difficulty?

I'd appreciate any advice, preparation tips, or insights from people who have already passed it.

Thanks!

Red Hat 9.8 breaking stuff

In the last week I have run into major problems upgrading some systems from 9.6/7 to 9.8. One test system xrdp broke, and another host Infiniband drivers and IB passthrough devices broke.

Is anyone else seeing 9.8 break some major stuff?

The tokenomics of self-hosted LLMs | Red Hat Developer

Paying a cloud API per million tokens is straightforward until the invoice arrives. But when you move to self-hosted large language models (LLMs), the economics flip upside down: you pay for raw compute regardless of whether your GPUs are processing requests or idling.

For platform engineers and machine learning operations (MLOps) leads, tokenomics, the economics of how tokens are produced and what they effectively cost, requires looking at both what you spend and how much you serve.

redhat idm and entra id

A little confused, how exactly does hooking redhat idm into entra id work ? ( not windows ad ).

I understand that “user can be configured to authenticate using Microsoft Entra ID as external identity provider. With this method, IdM domain must be installed, and IdM user needs to be created before the user can authenticate with Microsoft Entra ID.”

So if I’ve got hundreds of users managed currently, I need to create all those on idm side and set them to use auth with entra ? Similarly , will the users in idm be able to benefit from other nice features of idm ? i.e managin their acces, sudoers and so on?

No cost Learning Paths available for Red Hat Enterprise Linux from Red Hat

As part of my role as a product manager at Red Hat, I’ve been working with one of the teams that write Learning Paths for Red Hat Enterprise Linux (RHEL). To date, we’ve published 13 step-by-step tutorials on the topic for our developer portal - all completely free and designed to help developers get hands-on experience.  I’ve posted about some of these before on Reddit, and seen some interest, but it seemed like it would be useful to have the current list aggregate into a single post to those interested.  You can get them through the portal, but you have to find learning paths on the site, then search specifically for the RHEL tag to do it. Anyhow, this is just a simple list.

One kernel feature, 93% system throughput gone: A Red Hat Enterprise Linux 10.2 kernel regression and how to mitigate it | Red Hat Developer

TL;DR — During performance validation of Red Hat Enterprise Linux 10.2, we identified a kernel scheduler regression that reduced system throughput by up to 93% on multi-NUMA instance types. The regression is bimodal: Workloads either run at full speed or experience severe CPU work starvation. Eliminate this throughput collapse at runtime without rebooting by disabling the NI_RANDOM scheduler feature:

echo NO_NI_RANDOM > /sys/kernel/debug/sched/features

Anybody use RHEL at home as a workstation as daily driving?

Just curious. Its gotten easier over the years to do so with flatpak and distrobox filling the spaces when you need newer software (and of course EPEL). Especially since you can get a license for RHEL workstation for personal use for free.

Machine provisioning - Done right

So many companies have tried to figure out machine provisioning and failed. IMO at least.

Over the last 20 years we have seen Zenworks, Intune, SCCM, WDS, PDQ Deploy, FOG, Clonezilla, and many more champions. All of these solutions had bits and pieces that I liked, however there have always been missing parts. I decided to dedicate some time this weekend to solving that.

I created a personal project: Bootforge! An entirely standalone, vendor agnostic, OS agnostic, agentless deployment utility with a web GUI!

My goal is to have a full cycle independent system deployment for RHEL and Windows. Where you can PXE boot a machine (or VM), and then the you can select your OS, Hardening (CIS or STIG), System options (Server that runs xyz, gui that does xyz, etc, etc), and much more customization.

I plan to integrate this into OpenShift (this will power the actual project gui and such), then also integrate AAP for OS configuration and such to make it fully autonomous. Currently ansible-core and openscap is what does the majority of it, so the project will only grow from here.

Any extra time for non-english speakers

I would like to know if there's any additional time given to test takers and country where the test is being taken whose mother's tongue is not English. I plan to take the exam sometime before the end of the year in one of the Nordic countries.

From past experience I know Cisco gave additional time for those whose mother tongue is not English, wondering if Red-Hat does likewise.

Linux Admins is RHCSA/RHCE still worth it in 2026?

Please for those working as Linux Administrators, what’s your experience been like? I’m thinking about going for the RHCSA and eventually RHCE. Do you think these certs though I hate to use the word cert but prefer the knowledge and experience gained however does it actually help open doors? Also, what skills would you recommend alongside them. I have good solid Linux background and know my way around but not on admin level

User password management. Question about the "chage" command

I am practicing for the RHCSA exam but i ran into a problem that i am unsure of why it occurs. When i try to set an expiration date for a user account using chage like this:

chage -E 2026-10-25 exampleuser    

I always appear to get the wrong date in the "Account expires" field when i verify:

chage -l exampleuser
Last password change                                    : Jul 07, 2026
Password expires                                        : never
Password inactive                                       : never
Account expires                                         : Oct 24, 2026
Minimum number of days between password change          : 0
Maximum number of days between password change          : 99999
Number of days of warning before password expires       : 7

I set it to 25th but when verifying it is set to the 24th and it always ends up off by 1 day like this no matter the date. Does anyone know why this happens?

Some additional information that i doubt matters is that i am in UTC+2 and system's time settings seem completely fine. I am worried that this could lead to a point deduction on the exam.

RHCSA Exam Experience & Connection Issues

I'm from Brazil and have been studying for the RHCSA since January. Last week, I started the RHCSA exam, but after 32 minutes I had to cancel it because the connection was so slow that I couldn't even open the first question.

I had run the system requirements test several times beforehand, and everything was fine.

During the exam, I first used a 500 Mbps Wi-Fi connection. After about 15 minutes, I restarted and tried again using a 5G smartphone hotspot. It was slightly better, but still far too slow to take the exam.

I opened a ticket with Red Hat Support, but they recommended doing the exam using a wired connection. I've now upgraded my internet to 1 Gbps and will take the next attempt using a CAT6 wired connection.

However, I'm honestly worried about the possibility of losing $300 if the same thing happens.

Is there any way to test the actual connection to the RHCSA exam environment beforehand and get some evidence that everything is stable and better? Can I schedule a test or experience session or otherwise verify that the connection is good enough before taking the exam again?

Any advice from people who have experienced something similar would be greatly appreciated.

Passed EX294 (285/300)

This was the RHEL 10 version.

It was a doozy, mainly due to the exam environment. I took this one a couple months after EX200. It’s mainly a test of endurance due to how much the environment rage-baits you. This is probably the most frustrated I have ever been taking an exam.

Main prep:

- The official AU294 course, used about 40 hours of lab time there, and about 2 months to go through the content

- Homelab (ProxMox: 1 control node, 3 RHEL10 managed hosts)

- I currently work as a sysadmin and manage a decent amount of Ubuntu/RHEL machines

I finished with about 30 minutes to spare. I did not use ansible-navigator as it seemed to be broken. I wasted 20 minutes troubleshooting what ultimately seemed to be an issue with the exam environment.

I HIGHLY recommend taking this in person. Unfortunately the closest testing center was 8 hours away. I used a wired connection and the session would freeze every 10 seconds, and if you were typing while it froze it would send your input like 30 times. This happens CONSTANTLY.

For example, if you were backspacing a couple times and it froze, you would end up deleting 4 lines lol. I think I would have finished in 2 hours if it wasn’t for the constant Ctrl-Z’ing.

I recommend getting very comfortable with ansible_facts, conditional logic, and regex.

Good luck to the folks getting ready to take it. The official course is not completely adequate prep, especially regarding Jinja.
