Question

You are building an app named App1 that will monitor thousands of sensors across multiple sites. The app will include the resources shown in the following table. You need to recommend a real-time analytics solution for App1. The solution must meet the following requirements: - Perform analytics on the sensor data in real time. - Ensure that the solution scales dynamically. - Minimize development effort. - Minimize costs. What is the minimum number of Azure Stream Analytics jobs you should deploy?

Why each option

A single Azure Stream Analytics job is sufficient to meet the requirements for real-time sensor data analytics, leveraging its ability to handle multiple inputs/outputs, dynamic scaling, and minimize costs and development effort.

A1
B2

Deploying two Azure Stream Analytics jobs would introduce additional management complexity and incur higher costs without providing a clear functional advantage if the analytics logic can be consolidated into a single job.

C3

Three Azure Stream Analytics jobs would result in increased operational overhead and higher billing compared to a single job solution, which is typically sufficient for unified real-time analytics requirements.

D4

Four Azure Stream Analytics jobs would significantly raise the total cost of ownership and management complexity, contrary to the requirement to minimize costs and development effort.
