INTRODUCTION *
The Tennessee IoT Infrastructure Technician Certification examination evaluates the
knowledge, skills, and practical competencies required for deploying, maintaining, securing,
and troubleshooting Internet of Things (IoT) infrastructure. Candidates are assessed on
,networking principles, device integration, security practices, cloud connectivity, regulatory
compliance, and operational procedures. The examination includes multiple-choice and
scenario-based questions designed to measure both theoretical understanding and practical
decision-making abilities. Emphasis is placed on real-world applications, problem-solving,
risk management, and professional judgment to ensure technicians can effectively support
modern IoT environments across industrial, commercial, municipal, and enterprise
deployments.
SECTION ONE (QUESTIONS 1–50)
1. What is the primary purpose of an IoT gateway?
A. To generate electrical power for sensors
B. To connect IoT devices with broader networks and processing systems
C. To replace all cloud services
D. To encrypt physical infrastructure
🟢 Correct Answer: B. To connect IoT devices with broader networks and processing
systems
🔴 Explanation: IoT gateways aggregate device data, perform protocol translation, and
connect edge devices to cloud or enterprise systems.
2. Which protocol is commonly used for lightweight IoT messaging?
,A. MQTT
B. FTP
C. SMTP
D. SNMP
🟢 Correct Answer: A. MQTT
🔴 Explanation: MQTT is designed for low-bandwidth, resource-constrained environments
common in IoT deployments.
3. Which component typically measures environmental conditions?
A. Router
B. Firewall
C. Sensor
D. Hypervisor
🟢 Correct Answer: C. Sensor
🔴 Explanation: Sensors collect data such as temperature, humidity, pressure, and motion.
4. An actuator's primary function is to:
A. Store data permanently
B. Analyze cloud workloads
C. Generate encryption keys
D. Perform physical actions based on commands
, 🟢 Correct Answer: D. Perform physical actions based on commands
🔴 Explanation: Actuators convert control signals into physical movement or actions.
5. What is edge computing?
A. Processing data near the source rather than in a centralized cloud
B. A type of network cable
C. A wireless antenna standard
D. A backup power technology
🟢 Correct Answer: A. Processing data near the source rather than in a centralized cloud
🔴 Explanation: Edge computing reduces latency and bandwidth consumption by
processing data locally.
6. Which wireless technology is commonly used for short-range, low-power IoT
communication?
A. Bluetooth Low Energy (BLE)
B. Fiber Channel
C. DSL
D. Satellite TV
🟢 Correct Answer: A. Bluetooth Low Energy (BLE)
