Eccouncil 112-51 Exam - 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.

It's cool how tech helps with health, but I wonder about privacy.

I thought it was Device-to-gateway, but cloud makes sense too.

Could it be device-to-gateway? I just can't recall if the gateway is necessary for cloud communication in this scenario.

I practiced a similar question, and I feel like this is definitely not device-to-device since there's no direct communication between two devices here.

I'm not entirely sure, but I remember something about device-to-gateway models involving local processing. This seems more like a direct connection to the cloud.

I think this might be the device-to-cloud model since the ECG data is sent to John's phone, which could be using cloud services.

I'm pretty confident this is a device-to-cloud model. The wearable device is sending data directly to John's mobile phone, which is then connected to the cloud. I'll select that option.

Wait, I'm a bit confused. Is the mobile phone considered the "gateway" in this case? Or is the cloud/server where the data is ultimately sent the gateway? I need to think this through more.

Okay, I think I've got this. The scenario describes a smart wearable device (the ECG) sending data to John's mobile phone, so it's likely a device-to-gateway model. I'll go with that.

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.
