COMPATIBILITY TEST

1. Click on Start Compatibility Check.
2. LiveUSB compatibility check checks for the presence of a valid remote
exam LiveUSB image.

Note: Run the compatibility test 2–3 business days before the exam date at
about the same time of day your exam is scheduled. Running the test well
in advance helps you work out any technical issues or reschedule the exam
if the system requirements are not met.
If a part of the test fails, you can rerun the failed test or the entire set of
tests in that page.

3. Select your time zone and click Accept

4. Network compatibility checks test your internet performance. Results while connecting to our remote systems will vary depending on a number of factors such as the load on your router at time of running the test and distance to our servers.

5. Hardware compatibility checks test your external webcam and
microphone functionality. Ensure that you are able to see a feed from
your external webcam as it is mandatory to conduct the exam. It is okay even if your video feed appears flipped in the hardware compatibility checks.
If the microphone volume test fails, try speaking while rerunning the test.
Play the sample audio file to hear yourself during playback and check the box to confirm.
If the microphone test continues to fail, reboot to the remote exam LiveUSB
environment, access settings and set the Input — Volume slider high for the input device you wish to use. Typically, you will find the system’s integrated microphone (if any) and the microphone of your external webcam listed as
input devices.

6. Streaming compatibility checks, test your system’s ability to connect to the media servers and the quality of the video feed. Connecting from heavily firewalled networks may affect media streaming. Try a personal internet connection instead.
The ability to read small ext off your photo ID card is important for the remote exam proctor to validate your identity. Hold your photo ID card close to the webcam feed and confirm if the text is clearly visible.
It is okay even if your video feed appears flipped. The exam proctor will be able to see your un-inverted feed.

7. Compatibility Check Summary provides a summary of all the tests. You can rerun failed tests or restart the whole test if needed. Accept and return to the main section once all tests are successful.

8. Return to the main section and press the power button of your computer briefly to get the prompt to shut the machine down.
9. Your exams section will display your scheduled exams about one hour before the start time. You can access the exam 10 minutes before the start time. Click on this section next to the compatibility check to proceed if you are going to start your exam.

FREQUENTLY ASKED QUESTIONS

Why does it take a very long time to download the Remote Exam Live USB image?

The Remote Exam Live USB image is approximately 2 GB in size. Download speeds can vary depending on a variety of factors such as the available bandwidth and download speed of your internet connection at the time of downloading, number of users connected to the same router, distance from your wifi router, hardware specifications etc.

Fedora Media Writer throws errors while creating a Live USB on Windows 10

There are a few errors seen occasionally when Fedora Media Writer is used to create a Live USB from an iso file in Windows 10. Some of the screenshots given below.

1. The Remote Exam image size is at the borderline of 4GB and hence using an old 4GB thumb drive will cause the above error as the actual size of the image exceeds 4000 Megabytes. Use a drive that is 8 GB or larger in size.
2. Fedora Media Writer saves the ISO to your USB and then reads it back to verify that it gets the same data back as it wrote. If the read does not match the write, FMW will show an error saying ‘Your Disk is Probably Damaged’. This is a very stark message which actually means “Warning — there are inconsistencies between what was written and what was read back”. There are many possible reasons why the read might not match the write and it doesn’t always necessarily mean that the write failed or that the USB will not work. You can ignore this message on an otherwise known good USB and continue using the same.

Click on ‘Cancel’ to exit Fedora Media Writer, reboot your system and try to boot from the USB drive. If it boots successfully to the Remote Exam image, the USB drive and the image on it is fine and can be used for your exam.

1. Clicking on the Retry button and re-attempting the write process may fix the error
2. The above error may also appear if there is an existing Live USB in the disk already. The presence of a Live USB will be detected by FMW and a ‘Restore’ option will be available to format the drive. Click on Restore, finish the format process and reattempt the process of creating a Live USB.

After the exam, how do I reformat my USB drive?

Using Fedora Media Writer: Connect the USB drive to your computer and start Fedora Media Writer. ​You will see a prompt to restore the USB drive to “Factory Settings”: Follow the instructions to restore your USB drive to the Factory Settings

**Note to Windows Users: “Factory Settings” would most likely imply that your USB drive is formatted in the FAT32 file system. FAT32 does not allow transfer of files larger than 4GB and hence most Windows users prefer NTFS.
exFAT handles larger files and is Windows and Mac OS compatible. Hence, you will need to use an additional level of formatting using the Windows format utility.

Can I use a wireless internet connection?

Wifi is not advised. Wherever possible, use a wired internet connection for stability and compatibility. Wifi speeds can vary based on a variety of factors which may have an impact on your exam. The Remote Exam Live USB may not detect all wireless network adapters. If the wifi adapter of your computer is not detected by the Remote Exam Live USB image, then wired internet will be the only option.

How many free USB ports should be available for use during the exam?

You should ideally have a minimum of two USB ports available in a laptop for a bootable USB drive and an external web camera. In the case of a desktop computer, the requirement would be four ports for the following devices: One external webcam, USB drive, keyboard and mouse.

I am unable to download the Remote Exam Live USB image.

Your computer and the network you are connecting from must have the necessary privileges and permissions to download files from a third party source. The operating system used must have administrative (Windows) or root/sudo privilege (Linux/Mac). Firewalls and Security restrictions on your network setup might block such downloads. Try a personal computer and/or home network to perform these tasks.

Can I boot to the exam environment using a virtual machine rather than a USB drive?

No. The Remote Exam image must be loaded on a USB drive. Booting off a Virtual Machine is not allowed.

Can I create a bootable live USB by keeping my existing data in the same USB drive?

No. The process of live USB creation will wipe out any existing data and reformat your USB drive as needed.

Is a desktop computer allowed?

Yes

Is an iMac allowed?

Compatibility cannot be guaranteed. If your pre-exam test by booting in to the Remote Exam Live USB works fine, then you can proceed. A few things to note:

iMacs come with wireless keyboard and mouse. Wireless devices may not work.

Detection and stable performance of wifi internet is NOT guaranteed.

Using a wired keyboard and mouse and a wired internet on an iMac should work fine subject to successful pre-exam testing.

One external webcam with at least 1m cable and 90 degree field of view or more is required. The webcam must be focusable from 10 cm to 2 m.
