Exam MB-330 topic 2 question 12 discussion

It's D. Technically it can be either A or D, but the Microsoft guide follows option D. https://docs.microsoft.com/en-us/dynamics365/supply-chain/inventory/tasks/maintain-barcode-types

D is correct as per : https://docs.microsoft.com/en-us/dynamics365/supply-chain/inventory/tasks/maintain-barcode-types

Why Option A? Barcode Mask: The mask is the key feature for minimizing manual entry errors. It ensures the barcode follows a specific pattern (e.g., “#####-###” for a 5-digit prefix and 3-digit suffix), rejecting invalid inputs in real-time (e.g., letters where numbers are expected). Why Not the Others? B: No mask means weaker validation—max length alone doesn’t catch format errors. C: Security doesn’t influence entry accuracy—it’s about permissions, not data quality. D: “Size and max length” is vague and less effective than a mask, which combines format and length enforcement.

B is correct

The question is to setup and avoid error not set a bar code for a specific item. The process described in D is correct

I just checked it in the system and the give answer (b.) is correct.

Based on all the provided options, I think B is the correct option.

D is correct. The question is setting up barcodes in general to be used on items, not setting up a barcode for a specific item.

I think it's A. The question says "minimize the risk of errors on barcode entry" and with the mask, in theory, that risk would be minimized.

Technically they're all wrong. The type, min/max length and size are all defined on the barcode setup. To create a new barcode for an item, you navigate to the released product, define the barcode setup , qty and UoM. I think B is just the least wrong option here

I think D is not correct as the question demands bar code to be entered manually but D does not specify which item the newly created barcode is referred to.

I also think it's A. The reason why it can't be B is because: a. You cannot setup max length of the bar code through the item. b. When it says 'minimize' the risk, the risk would be minimize by configuring bar code once and using that setup. See reference below that explains what can be done on the item: https://docs.microsoft.com/en-us/dynamics365/supply-chain/pim/tasks/create-bar-code-product

I think that "warehouse scanning" implies that the barcode must be connected to an item. That is why it is B.

is there any references?

I also think A is correct answer

In my opinion the answer is A...
