CLA Logistics Technology & Information Systems 1 — Questions and Answers
Question 1: A Warehouse Management System (WMS) primarily helps an organization to:
- Direct and track all warehouse activities including receiving, putaway, picking, and shipping (Correct answer)
- Manage supplier contracts and purchase orders
- Generate transportation routes for delivery drivers
- Process customer invoices and payments
Correct answer: Direct and track all warehouse activities including receiving, putaway, picking, and shipping
A WMS controls and optimizes warehouse operations in real time, directing labor and equipment and maintaining accurate inventory location data.
Question 2: A Transportation Management System (TMS) helps logistics professionals primarily by:
- Planning, executing, and optimizing the physical movement of goods (Correct answer)
- Managing employee payroll and scheduling
- Tracking warehouse picking productivity
- Generating customer invoices for product sales
Correct answer: Planning, executing, and optimizing the physical movement of goods
A TMS provides tools for carrier selection, route optimization, load planning, freight auditing, and shipment visibility across modes.
Question 3: Electronic Data Interchange (EDI) in logistics enables trading partners to:
- Exchange standardized business documents electronically without manual re-entry (Correct answer)
- Track shipments using GPS in real time
- Automate warehouse picking using robotics
- Analyze carrier performance using machine learning
Correct answer: Exchange standardized business documents electronically without manual re-entry
EDI transmits structured documents such as purchase orders, advance ship notices, and invoices between systems in a standardized format, eliminating paper and manual keying.
Question 4: RFID technology in logistics differs from barcodes primarily because RFID:
- Can read multiple tags simultaneously without requiring line-of-sight scanning (Correct answer)
- Is less expensive to implement per unit
- Requires manual scanning of each item individually
- Stores less data than a standard barcode
Correct answer: Can read multiple tags simultaneously without requiring line-of-sight scanning
RFID readers can interrogate many tags at once through packaging and without direct line-of-sight, enabling bulk reads that are impossible with barcode scanners.
Question 5: An Enterprise Resource Planning (ERP) system benefits logistics operations by:
- Integrating financial, procurement, inventory, and logistics data into a single unified platform (Correct answer)
- Replacing all specialized logistics systems such as WMS and TMS
- Providing real-time GPS tracking of all freight shipments
- Automating carrier rate negotiations
Correct answer: Integrating financial, procurement, inventory, and logistics data into a single unified platform
ERP systems unify cross-functional data, enabling logistics teams to see order status, inventory levels, and financial impacts in one place.
Question 6: Which technology uses satellite signals to provide real-time location tracking of vehicles and assets in logistics?
- GPS (Global Positioning System) (Correct answer)
- EDI (Electronic Data Interchange)
- ERP (Enterprise Resource Planning)
- MRP (Material Requirements Planning)
Correct answer: GPS (Global Positioning System)
GPS receivers calculate precise geographic coordinates from satellite signals, enabling fleet tracking, route compliance, and estimated arrival time updates.
