Hi,

If there are any suspicion that the ISO was/is corrupted, then there is a simple verification check: calculate the sha256sum (or using the older, deprecated md5sum as indicated in the getting ready guide):

Look page 27:

How do I check the integrity of the remote exam live USB image I have
downloaded?
The MD5 checksum for the Live USB Image is: 0dd72ac558fc1afbf0c0e1fa4b366f10.

 

Source:

https://www.redhat.com/rhdc/managed-files/tr-remote-exams-preparation-ebook-f27382-202103-en_1.pdf 

 

I have verified for you, at the time of writing the md5sum of the currently available iso found at "https://static.redhat.com/downloads/training-certification/rhrexboot.iso" (as indicated in the prep guide) is indeed: 0dd72ac558fc1afbf0c0e1fa4b366f10.

 

Cheers,

Hi, just wanted to check - can I use a headset for mic and audio?

The only other mic I have is built into the webcam, and it wasn't loud enough in the test.

Thanks.

You are supposed to test the environment with Exam ISO even before you book
the exam ! and need to ensure the compatibility test is passed.

Anyway, try to contact the Red Hat support team ASAP.

Good luck.

Hi @tomcorcoran ,

Like @Gineesh said, all candidates are supposed to prepare their setup (the preparation guide says "2-3 days prior to your exam:").

Unfortunately in your case, that is a bit late and certainly stressful to do that a few hours before the exam...

I would suggest you try to work with the live support team, helping to prepare the Remote Exam, see the button at the end of page 1 of the preparation guide:

https://www.redhat.com/rhdc/managed-files/tr-remote-exams-preparation-ebook-f27382-202103-en_1.pdf 

Regarding your system, "Mac Big Sur" only indicate the OS and not the hardware.

That OS is from end 2020, so fairly recent. Quite likely you have the hardware with the infamous T2 security chipset. Do read at the end of the preparation guide, there are some FAQ explaining about the issues with that type of hardware...

I hope the live support can help you. Unfortunately, based on the recent OS; you probably have a recent MAC hardware, which is quite likely to have the T2 chip, and therefore hardware limitations preventing you to run Linux on that device... So as an external observer, without knowing all the facts. I think your situation is not very promising.

Good luck!

PS: I'm saying as an exam candidate myself, for further tries, nobody wants/need the last minute stress of preparing the remote exam environment on the exam day. It's best to read the preparation guide attentively and follow the advice written there.

We discussed with @tomcorcoran and it turns out the issue is using a recent MAC with the infamous T2 chip, indeed.

There's a list of hardware impacted on Apple website:

official Apple list of computer with T2 chip 

 

Anyway, bottom line, as indicated in the prep guide, Tom had to use another hardware without that T2 chip. He was also working things out with support to reschedule the exam at a later date!

Hi @Deanna ,

In Jan 2021, I created a remote exam bootable live USB. Is it still valid? I registered to take the exam on August 30, 2021.

I tried to compare the latest ISO from https://static.redhat.com/downloads/training-certification/rhrexboot.iso, with the one I downloaded in 1/2021.

❯ ll rhr*
-rw-r--r--@ 1 zji 1437522721 2.3G Aug 22 17:05 rhrexboot (1).iso
-rw-r--r--@ 1 zji 1437522721 2.3G Jan 8 2021 rhrexboot.iso

they have the same size, seems the same. But would like to check if I can use the I already have, so that I do not have to Create the disk image again.

Please confirm.

thanks

-Eric
