Eccouncil Exam 112-51 Topic 7 Question 20 Discussion

Actual exam question for Eccouncil's 112-51 exam

Question #: 20
Topic #: 7

John, from a remote location, was monitoring his bedridden grandfather's health condition at his home. John has placed a smart wearable ECG on his grandfather's wrist so that he can receive alerts to his mobile phone and can keep a track over his grandfather's health condition periodically.

Which of the following types of loT communication model was demonstrated in the above scenario?

ADevice-to-gateway model

BDevice-to-cloud model

CCloud-to-cloud communication model

DDevice-to-device model

Show Suggested Answer

Suggested Answer: B

A device-to-cloud model is a type of IoT communication model that connects the IoT devices directly to the cloud platform, where the data is stored, processed, and analyzed. The device-to-cloud model enables remote access, real-time monitoring, and scalability of IoT applications. The device-to-cloud model requires the IoT devices to have internet connectivity and cloud compatibility. In the above scenario, John used a device-to-cloud model to monitor his grandfather's health condition, as he placed a smart wearable ECG on his grandfather's wrist that sent the data to the cloud platform, where John could access it from his mobile phone and receive alerts periodically.

The device-to-gateway model is the obvious choice here. John's mobile device is acting as the gateway between the wearable and the remote monitoring system. Simple stuff!

Hmm, this is a tricky one. I'm not sure if it's device-to-device or device-to-cloud. Maybe John should ask his grandfather to do a tap dance to get a better signal.

I would say the device-to-cloud model is the correct answer. The wearable device is sending data directly to the cloud, which John can then access remotely.
