Microsoft Azure IoT Developer — Question 5

You plan to deploy an Azure IoT hub.
The IoT hub must support the following:
✑ Three Azure IoT Edge devices
✑ 2,500 IoT devices
Each IoT device will spend a 6 KB message every five seconds.
You need to size the IoT hub to support the devices. The solution must minimize costs.
What should you choose?

Answer options

• A. one unit of the S1 tier
• B. one unit of the B2 tier
• C. one unit of the B1 tier
• D. one unit of the S3 tier

Correct answer: D

Explanation

The S3 tier is designed to handle a large number of devices and high message throughput, making it suitable for this scenario with 2,500 IoT devices. The other options, such as the B1 and B2 tiers, do not provide sufficient capacity for the required message volume, while the S1 tier is also not adequate for the scale needed.
