IT and Technology IoT & Emerging Technologies 2

Question 1

What is the primary advantage of using blockchain for IoT data integrity?

Accepted Answer

Tamper-evident, decentralized record of device transactions

Answer

Blockchain creates an immutable, distributed ledger of IoT transactions, making it extremely difficult to alter historical sensor records without detection.

Question 2

Which machine learning deployment technique runs AI models directly on IoT devices?

Accepted Answer

TinyML / on-device inference

Answer

TinyML optimizes machine learning models to run on microcontrollers and low-power chips, enabling real-time AI inference without cloud connectivity.

Question 3

What does '5G network slicing' enable for IoT deployments?

Accepted Answer

Creating virtual dedicated networks with guaranteed QoS for specific IoT use cases

Answer

5G network slicing allows operators to create isolated virtual network segments with specific latency, bandwidth, and reliability guarantees tailored to different IoT applications.

Question 4

Which protocol does Matter (formerly Project CHIP) use as its underlying IP transport for smart home devices?

Accepted Answer

Thread (IPv6 mesh)

Answer

Matter uses Thread as its primary IP-based mesh networking protocol, running over IPv6 to provide reliable, low-power smart home device communication.

Question 5

What is the role of a TPM (Trusted Platform Module) chip in IoT security?

Accepted Answer

Securely storing cryptographic keys and device identity credentials in hardware

Answer

A TPM provides hardware-based storage for cryptographic keys, certificates, and measurements, enabling secure boot and device attestation.
