Hi Andres I did my RHCSA von RH8 and a colleague of me is preparing for the EX on RH9 and I see a lot of small differences for example vdo and container. I would recomend to do the exam in the version you prepared for. If you still have access to the training enviroment you can have a look at the different versions.
At end of January I've noticed that I couldn't attend the RHCSA on the date I've booked at end December (I've booked for V8). When rescheduling I was only offered in RHEL 9. I've complained, even asked here. Was informed that now is only availiable on RHEL 9.
So, re enroled in RH124 and RH134. To take the RHEL9 version. I've noticed that both courses have changes. The labs have changes. And been retraining and proacticing during the previous weeks on RHEL 9. I agree with @firstmatteo that there are many little changes. But this is the only option I have.
You can still have RHCE / RHCSA in RHELv8. After purchasing the exam you can find an option to schedule exam in v8 or v9.
If you want to know the difference between both version courses , take a look at the below summary :
RH124:
All narratives, exercises, and labs are updated to Red Hat Enterprise Linux 9 syntax.
The Red Hat Enterprise Linux introduction includes modern use cases and hybrid cloud computing.
The GNU info command is removed based on feedback that indicates limited use.
NetworkManager configuration file location changed starting in RHEL 8, and the network-scripts location is deprecated. The new configuration files use an INI format.
Remote file copying now uses Secure File Transfer Protocol (SFTP). Secure Copy Protocol (SCP) is removed due to a security flaw, and is no longer recommended for production use.
Package modules are temporarily deemphasized, because the earliest versions of RHEL 9 ship without software package modules while the module infrastructure continues to be built.
Red Hat support information and sites are updated to include newer tools and locations.
RH134:
Installing software now uses Simple Content Access for subscription management, which eliminates subscription attachment tasks and simplifies preparing registered systems.
Kickstart is updated with new syntax and functionality.
Modules are deemphasized in this update, but not removed. Engineering continues to develop the module infrastructure for RHEL 9, which will be delivered in a later RHEL 9 minor release.
Starting in RHEL 9, training courseware uses dnf commands for RPM package management. Yum remains supported, and using dnf aligns RHEL with the upstream community.
Network teaming is deprecated, due to a lack of upstream development, in favor of network bonding. The teamd service and the libteam library are deprecated in RHEL 9 and will be removed in the next major release.
Firewall infrastructure based on iptables, and the ability to migrate iptables configurations to NFT is removed. NFT is now the default firewall configuration and method.
The Access Control List chapter is removed based on feedback that indicates limited use.
SSH root access is now disabled by default. RHEL 9 adds new options to the root password configuration screen to lock the root account and to allow root SSH login with password..
Support for disabling SELinux through /etc/selinux/config is removed. SELinux can only be disabled through use of a kernel boot parameter.
The exFAT filesystem is now supported for external USB storage and data exchange with other operating systems, especially Windows.
VDO management is removed as a major topic, and is minimally introduced in the LVM overview, based on feedback that indicates limited use.
The container content has been redesigned to discuss use cases, and to include the latest podman syntax.
