I'm doing a practice exam to prepare for my DEV-401 Salesforce Developer certification exam. One of the questions is:
A developer changes a custom field type from Number to Text with a field length of 2. which of the following statements is true?
I picked: All the values in the number field will be converted to text
It's saying my answer is incorrect and it should be: Numbers less than 2 characters in length will be converted to text and numbers greater than 2 characters in length will be converted to text and truncated
I disagree, I tested it in Salesforce, I created a custom field of type Number with length 6. Created a record of the object and then modified the field type to Text with length of 2. I reopened the record and it's still has the 6 digits, the only different is that instead of 123,456 it's now 123456 (no comma).
Could it be that both answers are correct depending on which Salesforce release we are testing against? I tested against Winter 15.
If SF does changes like this, why do do they ask such questions on exam if in a few months what is correct now could become incorrect? Shouldn't they focus on fundamentals instead?
