IOT IoT Edge Computing 2

Question 1

What is the key advantage of 'local breakout' in IoT edge architectures?

Accepted Answer

Processing and responding to IoT events locally without sending traffic to the cloud, reducing latency and costs

Answer

Local breakout processes IoT data and makes decisions locally at the edge without routing traffic through the cloud, dramatically reducing latency and backhaul bandwidth costs.

Question 2

Which lightweight operating system or runtime is designed specifically for IoT edge and embedded devices?

Accepted Answer

FreeRTOS

Answer

FreeRTOS is a real-time operating system (RTOS) designed for microcontrollers and small embedded IoT devices with constrained memory and processing resources.

Question 3

What is 'edge caching' used for in IoT systems?

Accepted Answer

Storing frequently accessed or recent IoT data locally to reduce cloud queries and support offline operation

Answer

Edge caching stores recent IoT data or frequently accessed configurations locally, allowing applications to function during connectivity outages and reducing cloud API calls.

Question 4

What is the purpose of 'time-sensitive networking' (TSN) in industrial IoT edge computing?

Accepted Answer

IEEE standards that add deterministic, low-latency guarantees to Ethernet for real-time industrial control

Answer

Time-Sensitive Networking (TSN) extends standard Ethernet with IEEE standards to provide bounded latency and deterministic delivery required for real-time industrial IoT control.

Question 5

Which edge computing concept involves training a shared machine learning model across multiple IoT edge devices without centralizing raw data?

Accepted Answer

Federated learning

Answer

Federated learning trains ML models collaboratively across IoT edge devices by sharing only model updates (not raw data), preserving data privacy.
