Question 1

You are working on an app that will save the device metrics produced every minute by various IoT devices. You decide to collect the data for two entities; the devices and the device metrics produced by each device. You were about to create two containers for these identified entities but suddenly your data engineer suggests you place both entities in a single container, not two different containers. You would like to be able to track the general data of the device and the number of metrics collections per device. How could we keep track of these entities inside the container?

Options :

A : Add a new property to your device documents called metricscollectioncount and update it with the current number of metrics collection documents. Subtract 1 from the metricscollectioncount property when your app or Azure function adds a new metrics collection

B : Add a new property to your device documents called metricscollectioncount and update it with the current number of metrics collection documents. Add 1 to the metricscollectioncount property inside a transactional batch when your app or Azure function adds a new metrics collectionright

C : Use a GROUP BY parameter in your query and use the aggregate count to return the number of device metrics collections per device

D : Use a GROUP BY parameter in your query and use the aggregate sum to return the number of device metrics collections per device

Answer: B
