Welcome to Day 7 of the 30-day RHCSA challenge!

Resetting a lost root password is one of the most commonly tested tasks on the RHCSA — and one every sysadmin needs to know. Today we'll interrupt the boot process, drop into an emergency shell, and reset the root password from scratch.

By the end you'll be able to regain access to a system even when you're locked out of root.

What you'll learn in this video:

Interrupting GRUB at boot to edit the kernel line

Adding rd.break to reach the emergency shell

Remounting the filesystem as read-write

Changing the root password with passwd

Handling the SELinux relabel with .autorelabel

Rebooting into your system with the new password

How this fits into your 30-day RHCSA study plan

Good luck on your exam

I am a complete beginner and only complete the HTB linux fundamentals module and i want to get a Linux job. Claude pointed me to RHCSA course and here I am asking you where to learn it and how to pass the exam.

And I'm thinking to learn cyber security after i get my first linux job and is that a good idea or should I learn Cyber security now instead of all my focus on linux.

I'm currently in the middle of D0180 and still i wanted to study DO280. but for the folks who already passed it is this enough? Or is it a haaaard certificate???

Hey guys, I saw that there are multiple RHCE paths now. Does that mean I don't need to take the Ansible exam anymore to become an RHCE? Can I just do the Linux RHCE? I'm a bit confused..

Passing score:          210
Your score:             270

Result: PASS

Performance on exam objectives:

OBJECTIVE: SCORE
Manage basic networking: 100%
Understand and use essential tools: 89%
Operate running systems: 83%
Configure local storage: 100%
Create and configure file systems: 100%
Deploy, configure and maintain systems: 100%
Manage users and groups: 100%
Manage security: 100%
Manage containers: 50%

I was expecting 300/300 , verified all tasks by rebooting twice. Not really sure what went wrong with container tasks . Nonetheless satisfied with my results since i only spent 2-3 weeks practicing

Got this today after passing ex432: C3IFD2PW

Valid till 30.09.2016.

Good luck everyone ;)

Time to update those pesky shims 🫣

A quick question… i’m looking for Sander Van Vugt RHCSA course. And i see RHCSA RHEL 10 and RHSCA RHEL 9. Which one should i take .

Also, what is the difference between them?

Day 4/30: Configure Your IP Address with nmcli & nmtui (RHCSA Prep Series)

Welcome to Day 4 of the 30-day RHCSA challenge!

Networking is a core RHCSA skill, so today we're setting a static IP address two different ways: with nmcli on the command line and with the nmtui text interface. Both are must-know tools for the exam.

By the end you'll be able to configure network connections confidently, whether you prefer the CLI or a menu-driven interface.

Is it normal to get ghosted by Red Hat after a final interview? I have reached the final interview, and in the end, was told by the Hiring Manager that I will be receiving my offer letter by the end of next week. Fast forward multiple weeks, and it seems like I've gotten ghosted, but for some reason, my status in the portal is still sitting at "In Progress". Does anyone know if ghosting is normal in Red Hat and if the application portal status could be outdated now? I've also reached out to the recruiter and he's ignored my follow up.

Hello all, sorry if this has been answered here but I’m fairly new the Linux game and would like to know which of the RH certs would be more beneficial to shoot for. I’m not trying to punch above my weight class and be doomed from the start.

So I’ve been having the worst time with red hats customer support (I’m United States based specifically Florida ) . I tried to get the RHCSA EX200 but ran into a problem where red hat declined my card but still charged me 1000$ for two vouchers and it’s been over 8 hours and not one voucher.. I reached out to the training team and they were of no help and essentially told me there was no managers or management at red hat which I find strange for a company with such a large presence in the industry. I have been studying for this test for about 4 months and really would like to take it soon but I’m stumped on who to reach out to considering all parties seem to be of no help. I’m kindly asking if anyone here maybe can help direct me or help me out?

I'm investing in RHLS and I want to become an RHCA to potentially improve my chances when applying for a Red Hat Consultant and/or Architect when the opportunity presents itself.

I'm already RHCE Ansible, and I am wondering whether to start from scratch with OpenShift knowing that I already hold a CKA and I created K8s clusters in my personal lab, or continue with the Ansible track as I have worked more with Ansible (But not AAP) as it is potentially perceived as easier.

I wanted to get some answers and opinions on the following:

- Is RHCA OpenShift achievable in a year without production experience and with RHLS labs only? I studied the DO180 about year and half ago.

- Do you think RHCA Ansible is worth it for the goal to improve my shots at targeting Red Hat as an employer?

- Are the AAP exams hard? Compared to ex294, which I managed to score a 295/300.

Hi everyone, I am currently preparing for the LPIC-1 certification. Could you recommend the best practice exams or exam simulators that accurately reflect the actual test and ensure a passing score? Thanks in advance!
