Much difference between 2.2 and 2.5

[samatar_farah]

I have observed barely any difference between the current AAP 2.2 and the new 2.5. Are there many differences or not that many? I was unsure on perhaps waiting for the new DO374 and DO467 to update first or take those exams soon as they are now.

@samatar_farah -

So it really depends on what you mean by the question. Are there differences in the courses or in how AAP works at a fundamental level. In terms of technical automation, things are relatively the same. We have newer and updated modules and execution environments, but the bits work the same.

However, if we are talking about the web applications, there are some major differences in how things are setup as the "containerized" installation will be the preferred choice now and we now have the AAP Gateway which combines all the webUI interfaces into a single unified application across the multiple containers. The additional thing here (in addition to Controller and Private Automation Hub is the inclusion of EDA Controller for Event Driven Ansible. All of these are now accessible from the same web interface and containerized installation.

Another thing is that for RHEL10, at least for now, there will be no RPM installation for the Ansible Development Tools and instead will be the container integrated with VSCode now for Linux just as it is already used for MacOS and Windows.

Fundamentally, playbooks will work the same, but there will just be new approaches and tools to learn to develop and test the playbooks and there will be some new things introduced based on the changed webUI which integrates all the individual webUI components into a single AAP gateway. The main thing that has happened here is several more collections and modules are now used and needed to manage automation of the AAP platform and some of the older playbooks will need to be updated to use new collections and modules.

Ahh I see. Thank you very much for this detailed response, Travis! Helped a ton. For someone interested in furthering their Ansible training beyond the RHCE, would you advise them to take the 374 & 467 as is now?

Currently both AU374 & DO374 are available. I have covered 80% of the topic of DO374 & was planning to take the exam EX374V22, which is based on AAP 2.2. Then came across some articles on how poorly organized this exam is. What is your suggestion, go for the exam based on AAP 2.2 or 2.5? 

If I take the exam EX374V22, will it be counted for RHCA?

@Amalrasheed - 

So the DO374 is on AAPv2.2, if that is the course you took and covered the materials, that is the exam version I would take as long as EX374v2.2 is available. While most of the content and commands are the exact topics and overall process, some of the commands and tooling available in AAP 2.5 are newer and have changed and would not be supported in v2.2.

If you take either version of the exam (and pass) it will be counted as one of the required exams for attaining an RHCA. One thing I also want to point out, since there are two (2) live versions of the same exam, passing either version of the exam counts towards RHCA as one of the required exams, taking and passing BOTH versions of the exam would only cound as one (1) of the required exams to achieve an RHCA. In other words, pick the version of the exam you are prepared for, take it, and pass it. Passing the second version of the exam would do nothing for you in terms of counting as an additional credit towards the RHCA.
