True or False: Module variable assignments are inherited from the parent module and do not need to be explicitly set.

True or False: Module variable assignments are inherited from the parent module and do not need to be explicitly set.

• A. True
• B. False
• C. Only for certain variables
• D. It depends on the module type

Answer: (B)

When working with Terraform modules, each module has its own set of input variables, which are explicitly defined in the module's configuration files. These variables do not inherit values directly from parent modules; instead, they must be specified when you call the module. If a variable is not explicitly assigned a value in the parent module, Terraform will prompt for that value or fall back to a default (if one is set in the module). This requirement for explicit assignment ensures better modularity and clarity, as each module's dependencies are clearly defined and controlled by the parent module, rather than relying on potentially confusing inheritance from outside. Thus, it is essential to remember that variable assignments must be explicitly made to maintain the predictability of the module's behavior.
