CWLP Technology Systems 4 — Questions and Answers
Question 1: Which type of automated storage and retrieval system (AS/RS) uses cranes that travel along a fixed aisle to store and retrieve unit loads?
- Horizontal carousel
- Unit-load AS/RS (Correct answer)
- Vertical lift module (VLM)
- Goods-to-person robotic system
Correct answer: Unit-load AS/RS
Unit-load AS/RS systems use aisle-bound storage/retrieval machines (SRMs) or cranes to handle full pallets or large totes in high-bay racking.
Question 2: In a WMS, 'cycle counting' using ABC classification means:
- Counting all inventory once per cycle of 12 months
- Counting high-velocity (A) items more frequently than slow-moving (C) items (Correct answer)
- Assigning counting tasks alphabetically by product name
- Counting items only when a discrepancy is reported
Correct answer: Counting high-velocity (A) items more frequently than slow-moving (C) items
ABC cycle counting prioritizes frequent counts for high-value or high-velocity A items, reducing counts for B and C items to focus effort where accuracy matters most.
Question 3: What does 'lot traceability' in a WMS enable a warehouse to do?
- Track the physical location of a forklift
- Link products to their specific production batch for recall or quality purposes (Correct answer)
- Monitor the real-time position of delivery trucks
- Record which associate picked each individual item
Correct answer: Link products to their specific production batch for recall or quality purposes
Lot traceability allows the warehouse to record and query which lot or batch a product came from, critical for recalls, expiration management, and quality control.
Question 4: A 'goods-to-person' (GTP) fulfillment system improves productivity primarily by:
- Eliminating the need for a WMS
- Bringing products to a stationary picker rather than sending pickers to products (Correct answer)
- Using robots to pack and seal cartons autonomously
- Replacing all human workers with autonomous mobile robots
Correct answer: Bringing products to a stationary picker rather than sending pickers to products
GTP systems (carousels, VLMs, robotic shuttles) deliver inventory to an ergonomic workstation, eliminating travel time which can represent 50-70% of picking labor.
Question 5: Which data element in a GS1-128 barcode uniquely identifies a specific shipment unit globally?
- UPC (Universal Product Code)
- SSCC (Serial Shipping Container Code) (Correct answer)
- GLN (Global Location Number)
- GTIN-14
Correct answer: SSCC (Serial Shipping Container Code)
The SSCC is an 18-digit GS1 identifier that uniquely identifies a logistic unit (pallet or case) worldwide and is encoded in the GS1-128 barcode.
Question 6: In warehouse technology, 'put walls' are used primarily to:
- Separate hazardous materials from general inventory
- Sort and consolidate items from batch picks into individual customer orders (Correct answer)
- Store fragile items in padded compartments
- Display real-time KPI dashboards for managers
Correct answer: Sort and consolidate items from batch picks into individual customer orders
Put walls are physical sorting structures with cubbies where batch-picked items are sorted by destination order, enabling efficient order consolidation.
Question 7: What is the primary advantage of using a cloud-based WMS over an on-premise WMS?
- Higher data security due to on-site servers
- Lower upfront capital costs and faster deployment with automatic updates (Correct answer)
- Full customization without vendor limitations
- No requirement for internet connectivity
Correct answer: Lower upfront capital costs and faster deployment with automatic updates
Cloud WMS is delivered as SaaS, eliminating large hardware investments and IT maintenance while enabling faster implementations and continuous feature updates.
