A developer is configuring the cartridge path for a new B2C Commerce site based on the Storefront Reference Architecture (SFRA). The requirement is to override the standard checkout flow with custom logic defined in a cartridge named
app_custom_checkout, while ensuring core SFRA functionality remains available for other areas.Given the standard SFRA cartridges are
app_storefront_baseandmodules, which cartridge path configuration ensures the custom checkout logic takes precedence?Show answer details

During a code review, a Technical Architect notices the following pattern in a scheduled job script intended to export order data to an ERP system:
var orderIterator = dw.order.OrderMgr.searchOrders('status = {0}', 'creationDate desc', dw.order.Order.ORDER_STATUS_NEW); while (orderIterator.hasNext()) { var order = orderIterator.next(); // ... complex processing ... }The job fails with a
QuotaExceededExceptionon production when order volume is high. What is the root cause and the correct remediation?Show answer details
Correct answer: A
Iterating through large result sets using
searchOrdersandhasNext/nextkeeps objects in memory, eventually hitting the heap quota.OrderMgr.processOrders()is designed for batch processing; it loads objects into memory one by one (or in small batches) and clears them after the callback executes, preventing memory leaks.
