• Perception Layer, Middleware Layer, Application Layer

• Middleware Layer, Application Layer, Perception Layer

• Application Layer, Perception Layer, Middleware Layer

• Perception Layer, Application Layer, Middleware Layer

Which layer in the IoT architecture is most likely responsible for handling business logic and decision-making?

• Business Layer

• Network Layer

• 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
