HashiCorp Exam TA-002-P Topic 9 Question 28 Discussion

The Terraform language will automatically convert number and bool values to string values when needed, and vice-versa as long as the string contains a valid representation of a number or boolean value.

Example

* true converts to 'true', and vice-versa

* false converts to 'false', and vice-versa

* 15 converts to '15', and vice-versa

Where possible, Terraform automatically converts values from one type to another in order to produce the expected type. If this isn't possible, Terraform will produce a type mismatch error and you must update the

configuration with a more suitable expression.
