Re: Questions about getting ready for your Red Hat remote exam?

Hi @MohamedS ,

This behavior can occur when you try to mount the bootable image on your existing OS. Do you see this error while live booting into the USB?

For real-time assistance, I would recommend contacting the support team via the means described in your exam confirmation email.


Regards,

Re: Questions about getting ready for your Red Hat remote exam?

Hello.

I am unable to boot in to the RH Exam environment using the provided .iso file.  I've downloaded the .iso from:  https://static.redhat.com/downloads/training-certification/rhrexboot.iso

When I boot via USB to this .iso, I am loaded in to a simple grub menu, instead of the exam environment shown in the instructions.

Is there a different or updated .iso I should be using?

Thank you!

Re: Questions about getting ready for your Red Hat remote exam?

I downloaded this one a couple of days ago:
https://static.redhat.com/downloads/training-certification/rhrexboot.iso
used rufus to write it to a usb drive, and i can confirm it works fine when booted to a 10 year old laptop and passes all the device tests. I have not tried to boot it to my latest gen gaming pc, i suspect i may encounter problems. ready for my test on tuesday.

Re: Questions about getting ready for your Red Hat remote exam?

I tried taking my Red Hat exam online last year but could not.

After passing all the compatibility tests I connected to the proctor, the Red Hat provided OS found both cameras, but only allowed for the built-in camera to be used, not the external camera I had purchased.

I tried restarting the system with the built-in camera disabled, however the Red Hat OS still only enabled the built-in camera.

The proctor told me I could not take the test and that RH support would call me. The support solution was to unplug the external camera and plug it in once more. I had already done that many times, they had no further help to give. Red Hat told me they had never seen this issue before.

I have now ordered an EIVOTOR 720 webcam based on recommendations here. Is my issue a known one and has it been resolved?

Re: Questions about getting ready for your Red Hat remote exam?

Hi @johnnyx ,

It sounds like the first external camera used did not support the remote exam image. The remote exam image is based on Fedora32 and although most modern webcams are supported by default, some (older) models do not work on Fedora OS (Linux) and the remote exam image by extension.

The current version of the compatibility check cannot identify between external and internal web cameras and your pre-exam checks can pass because of the internal camera.
Please check if you were able to see the video feeds from the external web camera during the compatibility tests to ensure compatibility of the camera.

Regards,

Re: Questions about getting ready for your Red Hat remote exam?

The camera used for that exam attempt was brand new (late last year - 2020).

I tried the compatibility check yesterday with another brand new camera and still only the built-in camera is recognised. This is despite turning the camera off in every setting of the laptop.

I emailed this point to Red Hat - no response as yet.
