Exam MB-500 topic 3 question 47 discussion

Yes correct String Size, Label & Form Help

Unfortunately, "Extension" is ambiguous in this case, as it is possible to create an extension of an EDT string, as well as to create a new EDT string that derives from the EDT, in the classic sense. String size can't be changed in either case. Alignment can be changed when deriving from an EDT. Label and Help text can be changed in both cases. There is no property called "IsExtensible" on string EDTs. As the question asks for threee properties, it can be assumed it is talking about derived EDTs. The correct answer will thus be C - Form help, D - Alignment, E - Label.

There are several properties that can be customized on existing extended data types (EDTs) through extension: Label, Help text, Form help, Country region codes, String size You can only modify the value if the EDT does not extend from another EDT. You can only set the new String size to a value equal to or larger than the base EDT value. https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/modify-edt

Cannot be A because "String size can be defined only on root EDTs." This is an extension of an EDT, not the root.

I think for an EDT that is derived from another EDT, String size cannot be changed. So A might not be a correct option

I think A is not correct option as string size can be changed only when EDT is not getting extended from other EDT

ACD is correct, when you do EDT extension (.Extension) you can modify these properties: Display Length, Help Text, Label, String Size, Form Help, Tags

ACE is correct. A is weird, because you can't explicitly change the string size, but you can change the display length, meaning you can show only 10 chars from a 20 char string.

correct answer is ACE

string size cannot be modified. what's the correct answer?

correct
