Question 1: Which EDI transaction set is used to transmit an Advance Ship Notice (ASN) from a supplier to a retailer?
- EDI 850
- EDI 856 (Correct answer)
- EDI 810
- EDI 940

Question 2: In a warehouse management system, a 'license plate' typically refers to:
- A forklift identification tag
- A unique ID assigned to a handling unit or pallet (Correct answer)
- A vehicle entry permit for the dock
- A barcode on a shipping label
Correct answer: A unique ID assigned to a handling unit or pallet
A license plate (LP or SSCC) is a unique identifier assigned to a handling unit such as a pallet, enabling tracking of its entire contents as one entity.
Question 3: What is the primary purpose of a Transportation Management System (TMS)?
- Managing warehouse slot locations
- Planning, executing, and optimizing freight movements (Correct answer)
- Tracking employee productivity in the warehouse
- Generating purchase orders for replenishment
Correct answer: Planning, executing, and optimizing freight movements
A TMS is designed to plan and optimize the physical movement of goods, manage carriers, and track shipments in transit.
Question 4: Which technology enables real-time, two-way communication between warehouse devices and a host WMS without requiring manual data uploads?
- Batch scanning
- Radio Frequency (RF) communication (Correct answer)
- EDI batch processing
- Optical character recognition (OCR)
Correct answer: Radio Frequency (RF) communication
RF communication allows handheld scanners and mobile devices to send and receive data from the WMS in real time over a wireless network.
Question 5: A 'pick-to-light' system directs warehouse associates using:
- Audio prompts through a headset
- Illuminated displays mounted on shelving (Correct answer)
- Paper pick lists printed at the start of a shift
- A tablet showing a map of the warehouse
Correct answer: Illuminated displays mounted on shelving
Pick-to-light systems use LED displays at each storage location to indicate the item and quantity to be picked, reducing errors and increasing speed.

- Unit of measure
- Storage conditions
- Current inventory on-hand quantity (Correct answer)
- Product weight and dimensions
Correct answer: Current inventory on-hand quantity
Current inventory on-hand quantity is transactional data that changes frequently, whereas master data (UOM, dimensions, storage conditions) is relatively static.
Question 7: Which wireless standard is most commonly used for barcode scanners and handheld terminals communicating within a warehouse environment?
- Bluetooth 5.0
- IEEE 802.11 (Wi-Fi) (Correct answer)
- Zigbee
- NFC
Correct answer: IEEE 802.11 (Wi-Fi)
IEEE 802.11 Wi-Fi is the dominant wireless standard in warehouses due to its range, bandwidth, and compatibility with enterprise infrastructure.
