CPL Logistics Technology & WMS 3 — Questions and Answers
Question 1: Which EDI transaction set is used by a retailer to send an advance ship notice (ASN) acknowledgment back to a supplier?
- EDI 850
- EDI 856
- EDI 997 (Correct answer)
- EDI 810
Correct answer: EDI 997
EDI 997 is the Functional Acknowledgment transaction set, confirming that a trading partner received and processed an EDI document such as an ASN (856).
Question 2: A WMS uses 'task interleaving' to improve productivity. What does this mean?
- Assigning the same task to multiple workers for redundancy
- Combining putaway and replenishment tasks into a single user trip (Correct answer)
- Mixing pick tasks from multiple orders in one pass
- Alternating between manual and automated pick methods
Correct answer: Combining putaway and replenishment tasks into a single user trip
Task interleaving directs workers to perform a complementary task (e.g., putaway) on the return trip after completing a pick, eliminating empty travel.
Question 3: In transportation management systems (TMS), 'load tendering' refers to:
- The process of weighing and measuring freight before shipment
- Officially offering a load to a carrier and receiving acceptance or rejection (Correct answer)
- Calculating fuel surcharges based on distance
- Auditing carrier invoices against contracted rates
Correct answer: Officially offering a load to a carrier and receiving acceptance or rejection
Load tendering is the formal process by which a shipper offers a shipment to a carrier, who then accepts or declines the load.
Question 4: Which WMS receiving process verifies that inbound quantities and item details match the purchase order BEFORE physically putting inventory away?
- Blind receiving
- PO-based receiving (Correct answer)
- Cross-docking
- Directed receiving
Correct answer: PO-based receiving
PO-based receiving requires workers to scan or enter item data that the WMS validates against the open purchase order before accepting the inventory.
Question 5: A company implements a voice-directed picking system. Which benefit is MOST directly associated with this technology?
- Elimination of all barcode scanning in the warehouse
- Hands-free and eyes-free operation that improves pick accuracy and speed (Correct answer)
- Automatic replenishment of pick face locations
- Real-time integration with carrier tracking portals
Correct answer: Hands-free and eyes-free operation that improves pick accuracy and speed
Voice-directed picking frees workers' hands and eyes from handheld scanners, typically increasing pick speed and accuracy simultaneously.
Question 6: What is the function of a 'license plate number' (LPN) in a WMS?
- A DOT-required label for hazardous material shipments
- A unique identifier assigned to a handling unit that tracks it as a single entity through the warehouse (Correct answer)
- The carrier's trailer identification number entered at dock check-in
- A SKU-level barcode printed during receiving
Correct answer: A unique identifier assigned to a handling unit that tracks it as a single entity through the warehouse
An LPN is a serialized label applied to a pallet, tote, or carton that allows the WMS to track and move the entire unit without scanning each individual item.
Question 7: Which metric measures the percentage of orders shipped complete and on time without damage or documentation errors?
- Order fill rate
- On-time in-full (OTIF)
- Perfect order rate (Correct answer)
- Inventory accuracy
Correct answer: Perfect order rate
Perfect order rate captures all four dimensions of order quality—complete, on time, undamaged, and correctly documented—in a single composite metric.
