After downloading the rhrexboot.iso, the md5sum does not match the documented 0dd72ac558fc1afbf0c0e1fa4b366f10. I tried the download several times.

Using dd to write it to an 32 GB USB stick, does not give a bootable device with Secure Boot enabled.
Should I disable Secure Boot?

The checksum in the PDF is not valid. The correct one is:
478157b7675223468d83253a241a1fd5
Yes, Secure boot has to be disabled in order to boot this ISO

I am getting a 'Selected boot image did not authenticate' error when I try to boot from the USB image. Any idea how to get around this?

Nevermind, I was able to get past it by disabling secure boot in the BIOS. So if anyone else runs into this, it is one possible solution

Hi,

The Latest version ISO is Encrypted and hence you are unable to boot while Secureboot option is enabled. You can also boot using  the older version image (UnEncrypted) in case you do not have permission to change the BIOS settings.

I have a HP Pavilion laptop and the test environment is not able to play sounds. Microphone works, but no audio out.

Hi,

Dummy speakers may be detected. No worries as speakers are not mandaotry for the Remote Exam. Your Conversation with Proctor will be through chatbot. Kindly make sure your Mic volume is adequate and the External camera feeds are clear.

I downloaded the Live USB from the link on page 5 of https://www.redhat.com/rhdc/managed-files/tr-remote-exams-preparation-ebook-f27382-202103-en_2.pdf

The md5sum does not match the one written on page 33.

$ md5sum rhrexboot.iso
478157b7675223468d83253a241a1fd5 *rhrexboot.iso

[AnithaRaaji]

Yes, the PDF has to be updated with current version MD5 

 478157b7675223468d83253a241a1fd5

The boot screen of the current version will show RHRE.v20220719.F.46ea0c7

Hi Patryk
Some internal devices got disconnected after you connected a docking station? Asking if others experienced the same?
Not having enough information, I try to share my opinion.
I assume you reffer to using an external docking statin. The dock usually combines many input/output ports so requires big transfer speeds. Since several years, laptops do not have dock specialised port usualy located at the bottom. They use USB 3 or more often Thunderbolt protocol running in USB-C - like socket.
The reason some devices do not work over or whwn connection the external thunderbolt dock is that Fedora is not properly compatible with the thunderbolt protocol and supplies the dock with only USB speed. Therefore, come connected devices cannot work.
I would not use the external dock, I would use individual USB adapters and connect Network using this. Also, Display port to connect the external monitor is better than HDMI. But it depends on the wiring. Simply, connect those all devices you have directly to the USB of the laptop, use USB hub and avoid any Thunderbolt conversion your external dock is probably using.
