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?
I completely sympathize. I wouldn't think a student would be expected (or allowed) to authenticate to external repos. Neither would I expect an exam taker to be given a login to an external registry, or allowed to use a RHN or other account to do it. I can say for certain that if repos are housed inside the exam environment, the method I outlined above should do it with 'yum repolist all.' Ricardo says in the RH124 v8 course to make sure the file extension is .repo. I've made the same error during exercises occasionally, forgetting the .repo extension altogether. Though that is quickly remedied.
I know this is frustrating. When I recertified for RHEL 7 I had to retake the exam several times even though I had passed for RHEL 4 & 6 on the first attempts with them. The exams are really tough but there is a reason for that. Once one has passed these very tough tests, the reputation of toughness enhances our value in the job market.
On your concern about registration, RHEL does not need to be registered via subscription manager to use local repos. You will probably get a warning that the system should be registered but this does not stop the system from using local repos.
While I can't state exactly how, that would be prohibited, I can tell you that I was able to login and complete the exam successfully. It is not easy, it is possible.
Yesterday I had my exam and I am also not able to access node2.
This is the official guide: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/configuring_basic_syst...
I tried rw init=/sysroot/bin/sh and I also tried rd.break but not able to login into node2 it was asking root passwod for maintenance.
If I cannot login how I will perform node2 tasks.
@cmatternIs there any other way to reset node2 root passwd ?
init=/sysroot/bin/sh wouldn't work anyway as that path doesn't exist at that point in the boot sequence.
init=/bin/bash does work (I just did it to verify).
One would expect that a candiate for RHCSA (RHEL v9) would know that /sysroot/bin/sh isn't a valid path.
That is true, we do not teach those paths.
To make matters worse, init=/bin/bash is not in the RH134 course as a way to meet this published objective, "Interrupt the boot process in order to gain access to a system." The content still shows rd.break
My response was a bit snippy (rude, even). My only defense is this: People taking the RHCSA exam should have practiced this.
If they had, they would have known that rd.break and init=/sysroot/bin/sh don't work on RHEL 9.0
