HOTSPOT - For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Hot Area:
Option C says it sends the "readingS" once a day, which makes me think it has multiple readings and wait to send them all once a day. So with given information I'm more inclined to Yes, Yes, No.
Yes | Yes | No
C is No because the electric meter does not send EVERY change it registers immediately, it just gives you daily data, which might contain just one reading, or hourly readings, or readings for each minute.
Y, Y, N.
Streaming is synonymous with low latency (usually fractions of a second). 24 hour interval/latency does not constitute streaming in this scenario.
the device sends the readings --> so it is IOT Hub streaming. I believe if they mentioned, job reads the readings from devices over night, it would mean a batch process is triggered to read ALL devices. but here our streaming job is running and waiting any devices to send the data.
Read the sentences carefully. They give different solutions architecture scenarios. Where capturing data from devices and batch the information once per day is one thing, another is to stream data in real time to be processed. The electric meter is a typical example of batch. The sensors as being critical in real time is streaming (if something fails you need to provision a solution in real time). The payments one is a typical example of processing in batch by querying a big amount of information. I agree with the responses.
There is no buffering in electricity metrics. The data is sent once a day with no processing at all. It is a real time information at the time the device sends it.
I think the answer should be Yes, Yes, Yes. The option C is talking about a device that sends data once a day but it is the frequency in which that device works, it is not accumulating data and then sending it. When the data is received it should be processed in real time.
Streaming assume that you can do aggregates and simple operations, commonly in time windows, 1 update per day doesn't allow you to keep enough data in memory to do some statistics. Probably a likewise scenario is more to store daily recaps than reacting near real-time to events.
Yes,Yes,Yes. An electric meter is an IOT device, with an interval of 1 day. It is real time data from the device and can flow from an IOT Hub to Azure in real time as a stream
