Understanding IoT Communication Models

What is the primary characteristic of the Request Response model?

• Asynchronous communication between client and server.

• Unidirectional data flow from server to client.

• No communication between client and server.

• Synchronous communication between client and server.

In the Publish Subscribe model, what role does the publisher play?

• The publisher only listens for messages from other publishers.

• The publisher receives messages from subscribers.

• The publisher produces and sends messages to subscribers.

• The publisher manages the storage of messages.

How does the Push Pull model differ from the Request Response model?

• The Request Response model allows for unsolicited data transmission.

• The Push Pull model is based on server-initiated requests.

• The Request Response model transmits data continuously without waiting for requests.

• The Push Pull model allows for unsolicited data transmission, whereas the Request Response model is based on client-initiated requests.

What is an exclusive pair model in IoT communication?

• An exclusive pair model in IoT communication is a framework for direct, secure communication between two devices.

• A model for communication between multiple devices simultaneously.

• A framework that only allows communication through a central server.

• A method for broadcasting messages to all devices in a network.

Which model is best suited for real-time data streaming?

• Apache Spark

• RabbitMQ

• Amazon SQS

• Apache Kafka

What are the advantages of using the Publish Subscribe model?

• Increased complexity of components

• Reduced system performance

• Decoupling of components, scalability, flexibility in message routing, and improved system resilience.

• Limited message routing options

In which scenario would you prefer the Push Pull model?

• When managing fluctuating demand and varying lead times in supply chains.

• When demand is stable and predictable.

• When lead times are consistently short.

• When inventory levels are always high.

How does the Request Response model handle multiple clients?

• The Request Response model manages multiple clients by processing each request independently and concurrently.

• It processes all requests in a single thread sequentially.

• It ignores additional clients until the current request is completed.

• It queues all requests and handles them one at a time.

What is a common use case for the exclusive pair model?

• Decision-making processes or binary classification tasks.

• Data storage solutions

• Network security protocols

• Image processing algorithms

Which IoT communication model is most efficient for low-latency applications?

• Client-Server model

• Peer-to-Peer model

• Publish-Subscribe model

• Request-Response model
