Simplistic concept of low-cost virtual training environment capable of automatic user input data evaluation/validation

Evaluation and validation user data during practical exams, trainings, interviews or another type of testing is tedious, error prone mission. The more difficult this mission becomes when there is more than one way for job-seeker or student to do the desired task. Setting up the environment consisting of multiple nodes on which the challenge should be accomplished is equally tedious also. This paper presents novel approach which makes this mission easier. We present an easy way how to setup environment based on open-source software which can be use in real world scenarios like training, testing or practicing.
