The certification exam is proctored remotely via streaming audio, video, and screen sharing feeds. The screensharing feed allows proctors to view candidates' desktops (including all monitors). The audio, video, and screen sharing feeds will be stored for a limited period of time in the event that there is a subsequent need for review.
Exams are delivered online and Candidates must provide their own computer with:
Current version of Chrome or Chromium
you don’t need to install a virtual machine, use a client machine, or anything beyond a Chrome or Chromium browser
Make sure you have third party cookies turned on for the duration of the exam.
Reliable internet access
Ensure others on the same internet connection are not performing activities that use excessive bandwidth (i.e. holding conference calls, streaming content, gaming, etc.)
A wired connection is often more stable and robust than a wireless connection
Turn off bandwidth-intensive services (e.g. file sync, dropbox, BitTorrent)
Microphone
Please check to make sure it is working before you start your exam session.

Ensure the webcam is capable of being moved as the proctor may ask you to pan your surroundings to check for potential violations of exam policy.
Try holding up your ID while viewing your webcam feed to ensure your placement and resolution are sufficient for the person viewing your feed to read your ID.
