What is the difference between Flexible and Scheduling custom
intervals? - ANSWER-Flexible custom interval you define an
interval and a period (lowest value takes precedence), Scheduling
is where you define a specific time(s) that you want the check to
happen (on the minute, on the hour etc).
How are transformations in pre-processing handled i.e. in what
order? - ANSWER-In the order they are defined.
What happens if a preprocessing step fails? - ANSWER-All
preprocessing stops for that item.
What are the three options for 'custom on fail' scenarios in
preprocessing? - ANSWER-Discard value (& no more steps are
processed), Set value to (value will be changed to defined value),
Set error to (item will become not supported with custom error).

value
What are the three main ways in which Items can become
unsupported? - ANSWER-On data collection time, In
preprocessing steps, Or when writing into database
What are the three ways in which Items may become
unsupported on data collection time? And how can you fix them? -
ANSWER-Wrong item key or parameters,
Timeout/communication error, Wrong credentials/incorrect
