  2. In mapping parameters, values change and the Informatica server saves the values in the repository and uses next time when you run the session.

A Correct answer
Explanation

Mapping parameters retain constant values throughout a session once initialized - they don't change during execution. Mapping variables (not parameters) can change values and the server saves them for reuse. Parameters CAN be used in expressions within transformations. The value of a mapping parameter is set at session start and cannot be changed using functions during execution - that's what variables are for.
