In scenarios with high cardinalities, such as allowing up to 700 devices for a voice offer, it's important to note that modeling children with large cardinalities can lead to processing inefficiencies for MACD operations (B), and that decomposition might fail when processing the maximum number of products (D). While EPC supports hierarchical modeling, large cardinalities require careful consideration to ensure system performance.References:Salesforce EPC documentation and best practices for product modeling.
