Question 51

You need to recommend a solution to keep device properties synced to IoT Hub. The solution must minimize data loss caused by the connectivity issues.
What should you include in the recommendation?

A.Azure Event Grid
B.a cloud-to-device message
C.loT Hub device twins
D.the loT Hub direct method

Correct Answer: C

Scenario: You discover connectivity issues between the IoT gateway devices and iothub1, which cause IoT devices to lose connectivity and messages.
To synchronize state information between a device and an IoT hub, you use device twins. A device twin is a JSON document, associated with a specific device, and stored by IoT Hub in the cloud where you can query them. A device twin contains desired properties, reported properties, and tags.

Question 55

You are planning a proof of concept (POC) that will use an Azure IoT hub.
You have two self-signed client authentication certificates named Cert1 and Cert2. Cert1 has a basic constraint that contains Subject Type=CA. Cert2 has a basic constraint that contains Subject Type=End Entity.
You need to identify which certificates to use.
What should you identify? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
