Perception Layer
Middleware Layer
Which of the following statements is true regarding IoT architectural models?
There is a single universally accepted standard reference architecture for IoT.
No standard reference architecture has been adopted for IoT.
Only the Internet of Things–Architecture (IoT-A) model is used for IoT.
The Industrial Internet Reference Architecture (IIRA) is the only model for IoT.
What is the name of the simple architecture used to categorize IoT enabling technologies in the chapter?
IoT five-layer model
TCP/IP model
RAMI4.0 model
OSI seven-layer model
Explain why the IoT five-layer model has been used extensively in recent publications, based on the information provided.
Because it is the only model available for IoT.
Because it captures many essences of other models, simplifies, and systematizes them.
Because it is mandated by international standards.
Because it is more complex than other models.
What protocol is used for data exchange in the Middleware layer of the IoT five-layer architectural model?
CoAP
ZigBee
RFID
Apache Spark
What types of devices are included in the perception layer of the IoT model?
Devices responsible for collecting data, such as object identifiers, temperature sensors, location sensors, and other sensors
Devices responsible for data storage and analysis
Devices responsible for user interface and display
Devices responsible for network routing only
Why do active devices in the perception layer often have the longest range?
Because they have larger batteries or are attached to power supplies
Because they rely on readers in close proximity
Because they use infrared signals
Because they do not transmit data
If a device relies on readers in close proximity for its energy supply, which classification does it belong to in the perception layer?
Passive
Semipassive
Active
Embedded
Which layer is considered the infrastructure layer in IoT because it transforms conventional sensors into smart, identified, and connected devices?
Network Layer
Application Layer
Presentation Layer
Physical Layer
Which of the following is assigned to a node when it connects to a network to enable communication with other nodes?
Identifier
Password
Encryption key
Firewall
Given a massive network, how do addressing techniques contribute to network management?
By encrypting all data transmissions
By enabling the assignment of unique network addresses to nodes
By increasing the network speed
By reducing the number of devices connected
Which communication technology is particularly useful for ad hoc configurations in IoT?
Wi-Fi
Z-Wave
Power-Line Communication (PLC)
Long-Range Wide-Area Network (LoRa WAN)
Which characteristic is important for service registration and discovery in scalable and heterogeneous environments?
Autonomous, dynamic, and efficient
Manual, static, and slow
Expensive, complex, and unreliable
Centralized, rigid, and limited
Strategically, why is it important for nodes in an IoT environment to be able to analyze and control other nodes?
It enables autonomous decision-making and efficient network management
It increases the cost of the network
It reduces the need for data exchange
It limits the scalability of the network
