Exact Extracts from Salesforce CPQ (Advanced Configurator and CML Guide):
* "CML allows you to define typed relationships and constraints within bundles or configurable products."
* "The relation syntax defines cardinality using [min..max] where 0..5 means minimum zero and maximum five related components."
* "The require() statement conditionally enforces the inclusion of components based on logical conditions. The syntax require(condition, target{attribute=value}) is used to mandate configuration rules." Step-by-Step Reasoning:
* Requirement Analysis:
* The "House" can have up to five rooms (0..5).
* If more than three rooms exist, include MediaRoom with color = "Blue."
* CML Construction:
* Define relation rooms : Room[0..5] to allow zero to five rooms.
* Apply require() to enforce conditional inclusion based on count logic.
* Why B is Correct:It follows correct CML syntax and semantics:
* Proper cardinality expression [0..5].
* Correct conditional requirement referencing rooms[MediaRoom]{color="Blue"}.
* Why Others Are Incorrect:
* A: Cardinality [4,5] enforces a minimum of 4 rooms always-violates the "up to five" requirement.
* C: Misuses the House reference inside require(), which should target the related entity (rooms).
