IOT Architecture MCQ Questions
This section focuses on "IoT Architecture" in Internet of Things (IOT). These Multiple Choice Questions (MCQ) should be practiced to improve the Internet of Things (IOT) skills required for various interviews (campus interviews, walk-in interviews, company interviews), placements, entrance exams and other competitive examinations.
1. How many main components IoT mainly consists of?
A. 2
B. 3
C. 4
D. 5
View Answer
Ans : C
Explanation: IoT architecture technology mainly consists of four major components: Sensors/Devices, Gateways and Networks, Cloud/Management Service Layer and Application Layer.
2. _______ are the devices that are able to emit, accept and process data over the network.
A. Sensors
B. Gateways
C. Edge IT
D. Data Acquisition
View Answer
Ans : A
Explanation: Sensors or Actuators are the devices that are able to emit, accept and process data over the network.
3. ________ in the IoT Architecture is the hardware and software gateways that analyze and pre-process the data before transferring it to the cloud.
A. Data center
B. Edge IT
C. Gateways
D. Data Acquisition
View Answer
Ans : C
Explanation: Edge IT: Edge in the IoT Architecture is the hardware and software gateways that analyze and pre-process the data before transferring it to the cloud.
4. Which of the following is false?
A. APIs are glue
B. SOA components not loosely coupled
C. Kapua also provides a core integration framework.
D. None of the above
View Answer
Ans : B
Explanation: They are loosely coupled. That means every service is self-contained and exists alone logically.
5. Global Sensor Network is built for _________.
A. Increasing cost and increasing time for development
B. Reducing cost and increasing time for development
C. Reducing cost and time for development
D. Increasing cost and decreasing time for development
View Answer
Ans : C
Explanation: GSN is developed on the observation that most of the requirements for the application development sensor network are same. Having each sensor network development using its own custom software not only increases the cost but also takes time for development and deployment.
6. One of the main characteristics of Linked Stream Data is Live Streaming.
A. TRUE
B. FALSE
C. Can be true or false
D. None of the above
View Answer
Ans : A
Explanation: Most of the data on the web is from sensing devices. To facilitate the integration of data from sensed devices and other sources, both sensor stream source and data are being enriched with schematic descriptions, creating Linked Stream Data. It shows the live data depending on our application.
7. The SOA architecture is divided into how many layers?
A. 5 layers
B. 6 layers
C. 7 layers
D. 2 layers
View Answer
Ans : D
Explanation: The first which has direct relevance to the business as it carries out business functions. The second layer is the technical layer which talks about managing computer resources like a database, web server etc.
8. What happens when service providers change their operating system and communication protocols?
A. Inoperability and complexity arises
B. Only complexity arises
C. Only Inoperability arises
D. Nothing arises
View Answer
Ans : A
Explanation: Complexity arises when service providers change their operating system and communication protocols, which results in inoperability. Service providers use standard protocols and conventional interfaces to facilitate information among diverse services.
9. Ubiquitous service provision depends on _________
A. QoS
B. Management
C. Interoperability
D. Routing
View Answer
Ans : C
Explanation: Ubiquitous service provision depends on interoperability, not only for provisioning of a standard QoS controlled IP bearer, but also for cross domain naming, security, mobility, multicast, including fair compensation for utility provisioning.
10. API architecture not only includes critical elements but also caters for _________
A. System
B. Devices
C. Network
D. Multi homing
View Answer
Ans : D
Explanation: API architecture not only includes critical elements but also caters for multi homing, mobile networks with dynamic membership, and third party persistent storage based on indirection
