I am confused about the use of a wired keyboard, mouse, etc.

Does a laptop with a screen, keyboard, and touchpad(instead of a mouse) fine?

What is covering via a lid mean?

Hi @adharsh2208 

Please read this document carefully, it will answer your questions, and more:

https://learn.redhat.com/t5/Certification-Resources/Getting-Ready-for-your-Red-Hat-Remote-Exam/ba-p/... 

PS: there is no "covering via a lid", it says about closing the lid (the laptop screen), when there is another screen being used.

As for your laptop, it depends if it's the laptop screen or external screen (it's not very clear, since all laptops have a screen, I don't see the need to specify that again). If it's a laptop, you can use it with the laptop keyboard and laptop touchpad. If it's an external screen then you must close the lid, therefore the laptop screen + keyboard + touchpad won't be available and you need the external keyboard and mouse.

Cheers,

Thank you for the response. @JS_Learning 

I assume - I can also use my Laptop Cam? Instead of an external webcam.

Hi @adharsh2208 ,

As I said, please read the document carefully, there is no need for making assumptions (and getting it wrong). It clearly says external webcam.

In your best interest, I want to reiterate that it's the candidate responsability to "Get Ready" when choosing Remote Exams. If not willing to do that properly, it's probably best to look for alternative, like going to a testing center with a Kiosk computer ready for you.  It looks to me, the lack of attention displayed, could result in a proctor not allowing you to attend the exam, because not complying with some the requirements. That would probably means a lost exam entitlement and frustration for everyone!

Also the exams are rather hard, for me at least, and they do require a lot of attention to the questions and what it is asked to do, just a friendly reminder or warning!

Good luck with your preparations!

I just completed creating a bootable usb device per the remote exam instructions and upon rebooting for the first time in order to run a compatibility check the process hung showing "a start job is running for activation of dm raidsets"  with error of "dm raid [966] segfault at o ip 00007f13bdb2a563 sp 00007fff3fdb20a8 error 4 in libc-2.31,so" .

all subsequent reboots hung with the same error.  

How to resolve?    Need help please.   If this is the wrong forum to resolve errors please direct me to correct forum.

Hi,

We could try to help you here, but we would need a lot more of information... Without going into details, maybe some more obvious steps to avoid the problem(s) and help you getting ready:

  • Is there another computer you can try on?
  • What Network connection you are using, home? Work? Maybe a firewall is interfering?
  • Is there any security enabled like Secure Boot?
  • what is the "sha256 " checksum of the iso you used (to verify its integrity): sha256sum rhrexboot.iso

Note: I just used  an iso downloaded a few days ago, and my checksum is:

eda73a25d7d9b5eb51273c1773ee08297d17fb4430200125f3432d2f31ab594f

(I assume that the version I just downloaded is not corrupted and was not updated since then). If our checksum matches, it is unlikely to be about a corrupted iso.

 

The dm raid errors seems to indicate something is not going on with your raid drivers/controllers. If true, we would have collect more technical information and send it to the relevant team.

my answers:
Network connection used is at home via modem/router supplied by my internet provider. Not using WiFi. it's a simple router without firewall that supplies dhcp IP to any device that requests it. Again no firewall enabled or running - no ports blocked. There is no security enabled - no Secure Boot.
I ran a sha256 checksum against the downloaded iso file using windows certUtil and confirmed it matches your checksum exactly -
eda73a25d7d9b5eb51273c1773ee08297d17fb4430200125f3432d2f31ab594f. I even downloaded the iso several times, confirmed the hash and have the same result.
I am using simple SATA hard drives on my computer - no physical RAID controller - no RAID configured in bios. which brings up another question - why would the process be trying to TOUCH my hard drives? It's booting off of a 16 gig usb device - it shouldn't be configuring RAID for nothing but the usb device.

Hi @douradoden,

  • The checksum should be indicating that your iso is not corrupted. 

 

  • About the question about touching your hard drive(s)- Who said the Remote Exam environment is actually touching your hard drive(s)? I said the error message seems to indicate something- as a hint on initiating a technical investigation. I spoke about some hardware components based on the error message. Having said that, when a Live USB environment boot from a computer, it does access some part of the hardware, like CPU, memory, Keyboard, etc... Since it boots from a specific partition on the live usb, it does not access the hard drive data (which is a rather different thing than a hardware raid controller anyway).

Anyway, you could try on any other computer, to have more information about your live usb (if you have that option). You could also provide detailled technical information so we can check with the team creating the Live Exam Environment). We would need screen capture of the problem, all technical info on the computer (brand, version, components, etc...), same for your 16GB USB key. Description on how you are booting... Anything that can help.

Cheers,

"About the question about touching your hard drive(s)- Who said the
Remote Exam environment is actually touching your hard drive(s)?"

YOU SAID IT said it thats who. You said:"The dm raid errors seems to
indicate something is not going on with your raid drivers/controllers"
in a previous response.
Heres the link:
https://learn.redhat.com/t5/General/Questions-about-getting-ready-for-your-Red-Hat-remote-exam/m-p/1...
So you see YOU SAID IT!
I posted a simple question about RedHat's remote exam usb boot process
not working requesting a solution and now you want to argue with me?
The question is what is the dm raid set job trying to do - why is it
throwing a seg fault?
If you have no clue then bump it up to another engineer.
