Which elements are considered functional requirements for an IT system in training?

Functional requirements outline what a system should do and specify particular behaviors or functions that the system must support. In the context of an IT system for training, the elements that involve creating quizzes and accrediting courses are direct functionalities that the system must provide to fulfill its purpose effectively.

Creating quizzes is essential as it allows for assessment of the learners' understanding and knowledge retention, which is a core objective in a training environment. Accrediting courses is equally critical, as it confirms that a learner has completed the required training and can provide formal recognition of their achievement. These actions relate to the system's primary objectives of ensuring effective learning processes and validating competencies.

The other options, while they may involve components of a training system, either represent more passive actions, like watching videos or lectures, or actions that are supportive rather than functional, like monitoring attendance and backing up data. Monitoring attendance is a useful oversight tool, but not a direct function that determines how the learning and assessment processes themselves are conducted.
