Exam SC-400 topic 1 question 85 discussion

The correct answer is: 1. PRIMARY ELEMENT: match product serial numbers that contain a 10-character alphanumeric string. 2. CHARACTER PROXIMITY: ensure that the abbreviation of SN appears within 6 characters of each product serial number. "Supporting Elements" cannot replace "Character proximity" for this specific requirement. While "Supporting Elements" are used to validate the presence of secondary indicators (like keywords or patterns) near the primary element, they do not enforce a specific distance or proximity between elements. To ensure that the abbreviation "SN" appears within six characters of the product serial number, you must use the Character proximity setting. This setting explicitly defines the distance between the primary element (serial number) and the supporting keyword ("SN"). 3. ADDITIONAL CHECKS: exclude a test serial number of 1111111111 from a match. This allows you to define exclusions or exceptions, such as ignoring the test serial number.

This is a tricky one because you could combine all these checks into a single regex within the primary element or you could split it into primary and supporting elements.

To me 'Ensure that the abbreviation of SN appears within six characters of each product serial number.' should be character proximirty
