Candidate Requirements

The Linux Foundation has a zero tolerance rule in regards to Exam Misconduct. Our exams are monitored very carefully through a variety of methods - both during the live exam and after the exam is completed.

Any suspicious activity will be addressed and could result in consequences including, but not limited to, revoking your passing score and restricting your ability to take the exam again.

Linux Foundation Certification Exams are delivered online and are closely monitored by a proctor during the exam session via streaming audio, video and screensharing feeds. The screensharing feed allows proctors to view candidates' desktops (including monitor). 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.

If you’re interested in taking an online proctored exam through PSI and want a better understanding of what to expect, watch the PSI Online Proctoring Experience video.

System Requirements

Candidates should run the PSI Online Proctoring System Check to verify that their machine meets the technical requirements for taking a proctored exam.

The online proctored exam is taken on PSI's Proctoring Platform "Bridge", using the PSI Secure Browser (a web browser created to guarantee a secure exam delivery over a virtual connection).

The PSI Secure Browser download/installation will begin when you Select “Launch exam” from the PSI Dashboard.

PSI Secure Browser Download is made available to candidates at Exam Launch Time.

Candidates should review the Bridge FAQ Information, published by PSI, to prepare for the Secure Browser installation and be aware of how to resolve issues with the Installation/download or launch of their exam:

PSI Secure Browser FAQ (General) PSI Secure Browser - Linux OS Troubleshooting

Candidates must provide their own computer with:

  • Supported OS: Please review the System Requirements, published by PSI, in particular the supported Operating System Information.

  • All browsers are supported, however PSI highly recommends using the latest version of Google Chrome for the best exam scheduling experience, and because the secure browser is Chrome-based and will give a more accurate experience.

  • One active monitor (either built in or external) (NOTE: Dual Monitors are NOT supported) The Linux Foundation recommends a screen size of 15” or higher to support the ExamUI. The Linux Foundation recommends a screen resolution of 1080p.

  • 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)

    • HTTPS connectivity to AWS S3 endpoints like https://** is required, make sure your network environment is not blocking those requests (e.g. Firewall rules, HTTP Proxy, etc)

  • Microphone

    • Mac users may need to allow the PSI Secure Browser within their 'System Preferences: Security & Privacy: Privacy' settings for Microphone, Camera, Automation and Input Monitoring.

    • Please check to make sure it is working before you start your exam session.

  • Webcam

    • Ensure the webcam is capable of being moved as you will have to pan your surroundings to check for potential violations of exam policy.

    • Mac users may need to allow the PSI Secure Browser within their 'System Preferences: Security & Privacy: Privacy' settings for Microphone, Camera, Automation and Input Monitoring.

    • If you will be testing from an employer-provide ISP please ensure that streaming will be allowed using WebRTC.

Candidates are not allowed to have other applications or browser windows running except the one on which the Exam is being shown.

Important Information to Consider:

  • We strongly advise test takers to avoid using work-provided devices for their exams, as this practice can result in technical challenges. Although it is sometimes possible to initiate and access the exam on such devices, work devices often come with security features and work-related applications that can disrupt the exam software, causing technical complications.

  • To ensure a smooth exam experience, we recommend using personal devices without stringent security features, and on which you have the privileges needed to install applications and to end system process' and services.

  • Please disable firewalls or use a computer without a corporate firewall. Firewalls may interfere with installing the secure browser needed to take the test. .

  • You cannot take an exam using a virtual machine even though the compatibility check may not display any issues

  • If possible, stop any antivirus software from running, and antivirus scanning during the exam time.

  • If you are using a laptop, make sure that it's plugged into a power socket, so that the battery does not run out during the exam.
