- Which of the following is NOT a function of an IoT LAN?
Options:
a) Long range communication, global
b) World wide connections
c) Both (a) and (b)
d) Neither (a) Nor (b)
Answer:✅ c
Explanation:
IoT LANs are designed for local communication, not long-range or global networks. Global connectivity is the function of WANs or cloud networks.
- Statement: The integration of existing devices, smart devices, and constrained nodes in a singular framework is one of the reasons for the address crunch in IoT.
Options:
a) True
b) False
Answer:✅a
Explanation:
Yes, the increasing number of connected IoT devices leads to a shortage of IP addresses, hence the address crunch.
- Statement: “In Multi-homing, a node/network is connected to a single network for improved reliability.”
Options:
a) True
b) False
Answer:✅ b
Explanation:
False. Multi-homing refers to connecting a node/network to multiple networks, enhancing fault tolerance and reliability.
- Which of the following is/are the approach/approaches for multi-homing?
Options:
a) Proxy-based approach
b) Gateway-based approach
c) Both (a) and (b)
d) None of these
Answer:✅ c
Explanation:
Both proxy-based and gateway-based approaches are used to implement multi-homing in IoT networks.
- IPv6 uses _____________ notation for its representation.
Options:
a) Hexadecimal
b) Binary
c) Decimal
d) None of these
Answer:✅a
Explanation:
IPv6 addresses are represented using hexadecimal notation, making them more compact than binary.
- The parameters sensed by a sensor may be sent to the cloud for further processing.
Options:
a) False
b) True
Answer:✅ b
Explanation:
Yes, sensors in IoT send data to the cloud for processing, analytics, and storage.
- The IPv6 notation uses _______ number of bits to represent an address.
Options:
a) 64
b) 128
c) Both (a) and (b)
d) Neither (a) nor (b)
Answer:✅ b
Explanation:
IPv6 uses 128-bit addressing, which allows for a vast number of unique IP addresses.
- A sensor is –
Options:
a) Only sensitive to the measured property
b) Insensitive to any other property that what the sensor is made to sense
c) Both (a) and (b)
d) None of these
Answer:✅ c
Explanation:
A good sensor is only sensitive to what it’s designed to measure and insensitive to other variables.
- We classify sensors based on –
Options:
a) Output
b) Data type
c) Both (a) and (b)
d) None of these
Answer:✅ c
Explanation:
Sensors are classified by output type (analog/digital) and data type (temperature, pressure, etc.).
- Which of the following is correct statement?
Options:
a) Controlling AC loads using low DC signals
b) Relays are electromechanical
c) Relays are actuators
d) All of these
Answer:✅ d
Explanation:
All statements are correct. Relays are electromechanical actuators that can control high-power AC devices using low-voltage DC control signals.
- Based on the output, sensors are classified as ________.
Options:
a) Analog
b) Digital
c) Both (a) and (b)
d) Neither (a) nor (b)
Answer:✅ c
Explanation:
Sensors are either analog (continuous output) or digital (discrete output).
- Soft actuators are –
Options:
a) Polymer-based
b) Mechanical
c) Electromechanical
d) None of these
Answer:✅a
Explanation:
Soft actuators are made from polymers, allowing flexibility and adaptability in tasks like soft robotics.
