RH442EA - Red Hat Performance Tuning

[littlebigfab]

Hello,

I've just noticed an updated version of RH442 in the Early Access section.

What's new in it compared to the current one ? Is it based on RHEL8 ?

Is an updated EX442 exam to be released as well ?

Thanks!

Thanks!! I'll need some luck indeed, it's supposed to be one of the most difficult Red Hat exams! :/

I intend on giving it a try early next year

New tools, new concepts, enterprise and cloud, SSDs, etc, etc. There is a lot of new material.  Really, I just ask that you go look at the book because there is too much to list!  Oh, and by the way, the course just released TODAY!

I'm almost done with the course on Red Hat 7. Is the exam still available for 7, or do I need to take it on 8 now?

Hi @PeteCassetta,

You can take individual exam EX442V7K. It is the RHEL7-based one.

Good luck!!!

Thanks @littlebigfab, that's very reassuring. I couldn't find anything about that on Red Hat's site... Appreciate the info!

Hello !

I have almost completed this training course and it's really cool ! I'll write something about it afterward. You did an amazing job with it !

For now, I'm preparing for EX442, with only one week left before the exam :s

I come across the following unexpected behaviour at lab 11.5 : Tuning Network Utilization :

My team0 network teaming works fine, but after a reboot, the slave interfaces do not come back up. If I manually bring them up, then everything works fine again.

I wonder if it is normal due to the classroom virtual environment, or if there's something I don't get, or maybe a bug in the lab.

I'm pretty concerned because modifications usually have to persist across reboot in Red Hat exams in general.

Many thanks in advance for your help.

I found the trick with the following parameter to be set on the team:
