Frequently Asked Questions: CTAD
The Certified TARS Application Developer (CTAD) certification is ideal for users interested in demonstrating early proficiency and aptitude in microservices.
The CTAD demonstrates candidates' knowledge about developing and maintaining microservices in the TARS Framework. The specific areas include: installing and operating TARS in Docker, Kubernetes, or from source code; creating a microservices application using the TARS Framework in a chosen programming language; and awareness of the functions/plugins available to maintain or scale up microservices applications in TARS.
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.
The main function of the proctors during the exam is to facilitate the check-in process and to monitor the session. They do not, nor are they expected to, have the technical expertise to weigh in or provide insight on the exam servers or exam content. Proctoring for Linux Foundation Exams is explained here.
The online proctored exam is taken on PSI proctoring platform "Bridge", using the PSI Secure Browser (a web browser created to guarantee a secure exam delivery over a virtual connection).
The secure browser download/installation will being when you Select “Launch exam” from the PSI Dashboard.
Candidates must provide their own computer with:
- All browsers are supported, however PSI highly recommends using Chrome as the registration browser 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)
- Reliable internet access
