Resilience
Hardware Failure
Student exam data is continuously sent to the main server from the agent server located at the exam centre. In case of hardware failures at the exam centre, a new agent server is set up with latest data available from the main server.
Internet Connectivity Failure
Exam data is sent to the agent server at the exam centre. Entire exam is conducted locally at the exam centre. Therefore, any internet connectivity issues during the exam does not impact the exam in any way.
Power Failure
In an unfortunate event of a power failure on the client machines, the student's exam will resume from the same state when power failure occured.
