5. ________ Provide the means to create capability that reflects true awareness of the physical world and people.
a) Sensors
b) Heterogeneity
c) Security
d) Connectivity
View Answer
Explanation: Sensing technologies which includes Sensors provide the means to create capability that reflects true awareness of the physical world and people in it. The sensing information is simply the analogue input from the physical world.
6. ________ in IoT as one of the key characteristics, devices have different hardware platforms and networks.
a) Sensors
b) Heterogeneity
c) Security
d) Connectivity
View Answer
Explanation: Heterogeneity in IoT as one of the key characteristics, devices have different hardware platforms and networks. And can interact with other devices or services platforms through different networks.
7. IoT devices are naturally vulnerable to ________ threats.
a) Sensors
b) Heterogeneity
c) Security
d) Connectivity
View Answer
Explanation: IoT devices are naturally vulnerable to security threats. There is a high level of transparency and privacy issues with IoT.
8. Which challenge comes under IoT devices, reliable bidirectional signaling.
a) Signaling
b) Security
c) Presence detection
d) Power consumption
View Answer
Explanation: With connected IoT devices, reliable bidirectional signaling is essential for collecting and routing data between devices.
9. Which challenge comes under securing the information?
a) Signaling
b) Security
c) Presence detection
d) Power consumption
View Answer
Explanation: Security is a huge umbrella, but it’s paramount in Internet of Things connectivity.
10. ________ gives an exact, up to the second state of all devices on a network.
a) Signaling
b) Security
c) Presence detection
d) Power consumption
View Answer
Explanation: Its important to immediately know when an IoT device drops off the network and goes offline and when comes online back. Presence detection of IoT devices gives an exact, up to the second state of all devices on a network.
11. Which challenge comes when we use many devices on the same network?
a) Signaling
b) Security
c) Presence detection
d) Power consumption
View Answer
Explanation: You need minimal battery drain and low power consumption. You can’t afford to use up 100% of an IoT devices small and expensive embedded CPU power.
12. ________ a cellular network is expensive, especially with many IoT devices.
a) Signaling
b) Security
c) Bandwidth
d) Power consumption
View Answer
Explanation: In addition to power and CPU, bandwidth consumption is another challenge for IoT connectivity. Bandwidth on a cellular network is expensive, especially with many IoT devices.
