Failed RHCSA twice: it seems configuration not saved

[NeilYang]

I have been practicing redhat Linux in my virtual machine quite a lot and I am quite confident.

I felt really really bad to fail the exam twice.

It seems my node2 work was never saved in the previous exam and in this exam. 
Actually I have booted the node 2 twice and I definitely saw the storage related configuration was there. But I lost all the scores for this area. Last time, I got the reply that " one of your system did not reboot to a usable state and could not be graded"

I do not know what happened. It must be a very small, but extremely critical point I have missed. This never happen in my local virtual machine environment.

Can anybody help and give your hint?

Many thanks!

thank you @Shertster , I may have done some things wrong, but not to receive such score, also the 0% on user management it's impossible.

Hi @avanish7
They said that the correction was right, that some of my config was bad and
1 node didn't boot due to misconfig. I disagree but there's nothing I could.

Since my first attempt was failed before started due to an error on my
pendrive and I was not able to resolve it on time they allowed me a new
attempt. I hope you have another attempt or RH give another chance.

Best of luck!
