  2. To enable communication between devices

  3. To collect and transmit data

  4. To control devices remotely


Correct Option: A
Explanation:

Mobile IoT aims to connect various devices to the internet, allowing them to communicate with each other and exchange data.

Which technology is commonly used for short-range communication in Mobile IoT?

  1. Bluetooth

  2. Wi-Fi

  3. Cellular

  4. NFC


Correct Option: A
Explanation:

Bluetooth is widely used for short-range communication in Mobile IoT due to its low power consumption and ability to establish connections between nearby devices.

What is the primary function of a smart device in Mobile IoT?

  1. To collect data from sensors

  2. To process and analyze data

  3. To communicate with other devices

  4. To control actuators


Correct Option: A
Explanation:

Smart devices in Mobile IoT are equipped with sensors that collect data from the environment and transmit it to other devices or cloud platforms for further processing and analysis.

Which protocol is commonly used for communication between smart devices and cloud platforms in Mobile IoT?

  1. MQTT

  2. HTTP

  3. TCP/IP

  4. UDP


Correct Option: A
Explanation:

MQTT (Message Queuing Telemetry Transport) is a lightweight protocol designed for communication between IoT devices and cloud platforms. It is widely used in Mobile IoT due to its low bandwidth requirements and ability to handle large volumes of data.

What is the main challenge in securing Mobile IoT devices and networks?

  1. Lack of physical security

  2. Limited computational resources

  3. Vulnerability to cyberattacks

  4. High power consumption


Correct Option: C
Explanation:

Mobile IoT devices and networks are vulnerable to various cyberattacks, such as malware infections, phishing scams, and denial-of-service attacks, due to their limited security features and connectivity to the internet.

Which security measure is commonly implemented to protect Mobile IoT devices from unauthorized access?

  1. Encryption

  2. Authentication

  3. Firewalls

  4. Intrusion detection systems


Correct Option: B
Explanation:

Authentication mechanisms, such as passwords, biometrics, or digital certificates, are used to verify the identity of users or devices attempting to access Mobile IoT devices or networks.

What is the role of edge computing in Mobile IoT?

  1. To process data locally

  2. To reduce latency

  3. To improve security

  4. To conserve bandwidth


Correct Option: A
Explanation:

Edge computing involves processing data at the edge of the network, closer to the data source. In Mobile IoT, edge computing is used to process data locally on smart devices or edge gateways, reducing the need for data transmission to the cloud and improving response times.

Which technology is commonly used for long-range communication in Mobile IoT?

  1. Cellular

  2. Wi-Fi

  3. Bluetooth

  4. NFC

What is the primary benefit of using Mobile IoT in healthcare applications?

  1. Remote patient monitoring

  2. Improved patient care

  3. Reduced healthcare costs

  4. Increased patient satisfaction


Correct Option: A
Explanation:

Mobile IoT enables remote patient monitoring by collecting data from wearable devices or sensors and transmitting it to healthcare providers. This allows for continuous monitoring of vital signs, early detection of health issues, and timely intervention.

Which technology is commonly used for wireless charging of Mobile IoT devices?

  1. Qi

  2. NFC

  3. Bluetooth

  4. Wi-Fi


Correct Option: A
Explanation:

Qi is a widely adopted wireless charging standard for Mobile IoT devices. It uses inductive charging technology to transfer power wirelessly between a charging pad and a compatible device.

What is the primary challenge in deploying Mobile IoT solutions in remote areas?

  1. Lack of infrastructure

  2. Limited power supply

  3. Harsh environmental conditions

  4. High cost of deployment


Correct Option: A
Explanation:

Deploying Mobile IoT solutions in remote areas can be challenging due to the lack of existing infrastructure, such as cellular networks or reliable power sources. This can make it difficult to establish connectivity and ensure continuous operation of IoT devices.

Which technology is commonly used for indoor positioning in Mobile IoT applications?

  1. Wi-Fi

  2. Bluetooth

  3. GPS

  4. NFC


Correct Option: A
Explanation:

Wi-Fi-based indoor positioning systems use the received signal strength (RSS) from multiple Wi-Fi access points to estimate the location of a device. This technology is commonly used in Mobile IoT applications to provide accurate indoor positioning for asset tracking, navigation, and other location-based services.

What is the primary benefit of using Mobile IoT in smart city applications?

  1. Improved traffic management

  2. Enhanced public safety

  3. Efficient energy management

  4. Optimized waste collection


Correct Option: A
Explanation:

Mobile IoT can be used to collect data from traffic sensors, cameras, and other devices to monitor traffic conditions in real-time. This data can be used to optimize traffic flow, reduce congestion, and improve overall traffic management.

Which technology is commonly used for device-to-device communication in Mobile IoT?

  1. Bluetooth

  2. Wi-Fi Direct

  3. NFC

  4. Zigbee


Correct Option: A
Explanation:

Bluetooth is widely used for device-to-device communication in Mobile IoT. It allows devices to establish connections and exchange data directly without the need for a central access point or network infrastructure.
