GLP GLP Technology & Digital Logistics 1 — Questions and Answers
Question 1: What is the primary function of a Transportation Management System (TMS) in logistics operations?
- Managing employee payroll
- Planning, executing, and optimizing the movement of freight, including carrier selection and freight audit (Correct answer)
- Tracking customer purchase history
- Managing supplier quality audits
Correct answer: Planning, executing, and optimizing the movement of freight, including carrier selection and freight audit
A TMS automates freight planning, carrier selection, load optimization, shipment tracking, and freight bill auditing to reduce costs and improve service.
Question 2: Which technology uses radio waves to automatically identify and track tags attached to objects, enabling real-time inventory visibility without line-of-sight scanning?
- Barcode scanning
- RFID (Radio Frequency Identification) (Correct answer)
- GPS tracking
- EDI
Correct answer: RFID (Radio Frequency Identification)
RFID uses electromagnetic fields to read tags from a distance without requiring direct line of sight, enabling faster and more accurate inventory counts than barcodes.
Question 3: In logistics technology, what does EDI stand for and what is its core purpose?
- Electronic Data Interchange — the standardized computer-to-computer exchange of business documents between trading partners (Correct answer)
- Enterprise Data Integration — a database architecture system
- Electronic Delivery Instruction — a shipping label format
- Enhanced Distribution Index — a carrier performance metric
Correct answer: Electronic Data Interchange — the standardized computer-to-computer exchange of business documents between trading partners
EDI enables automated, standardized exchange of documents such as purchase orders, advance ship notices, and invoices between supply chain partners without manual intervention.
Question 4: Which type of automation uses software robots to mimic human actions in repetitive digital tasks such as data entry, order processing, and report generation in logistics back-offices?
- Autonomous mobile robots (AMRs)
- Robotic Process Automation (RPA) (Correct answer)
- Automated Storage and Retrieval Systems (AS/RS)
- Conveyor automation
Correct answer: Robotic Process Automation (RPA)
RPA deploys software bots that replicate human computer interactions to automate high-volume, rule-based administrative logistics tasks without changing underlying systems.
Question 5: What is the Internet of Things (IoT) primarily used for in cold chain logistics?
- Automating customer invoicing
- Real-time temperature and humidity monitoring of shipments to ensure product integrity throughout transit (Correct answer)
- Optimizing warehouse staffing schedules
- Processing customs declarations electronically
Correct answer: Real-time temperature and humidity monitoring of shipments to ensure product integrity throughout transit
IoT sensors embedded in cold chain shipments continuously transmit temperature, humidity, and location data, alerting managers to deviations before product spoilage occurs.
Question 6: A Warehouse Management System (WMS) improves pick accuracy by directing warehouse staff via which technology that provides step-by-step verbal picking instructions?
- RFID wristbands
- Voice-directed picking (voice picking) (Correct answer)
- Automated conveyor routing
- Augmented reality headsets
Correct answer: Voice-directed picking (voice picking)
Voice-directed picking uses voice recognition and audio instructions to guide workers through pick tasks hands-free, improving accuracy and throughput.
