Question

You have an Azure loT hub that receives series data from machinery. You need to build an app that will perform the following actions: - Perform anomaly detection across multiple correlated sensors - Identify the root cause of process stops. - Send incident alerts The solution must minimize development time. Which Azure service should you use?

Options

• AAzure Metrics Advisor
• BAzure AI Document Intelligence
• CAzure Machine teaming
• DAnomaly Detector

Explanation

To perform anomaly detection, root cause analysis, and send alerts on time-series IoT data with minimal development time, Azure Metrics Advisor is the optimal service.

Common mistakes.

• B. Azure AI Document Intelligence is used for extracting information from documents, not for time-series anomaly detection.
• C. Azure Machine Learning is a platform for building and deploying custom ML models, which would require significant development time compared to a ready-to-use service.
• D. Anomaly Detector is an API for detecting anomalies, but Azure Metrics Advisor provides a more comprehensive end-to-end monitoring solution including root cause analysis and alerting capabilities.

Concept tested. Azure AI service for time-series anomaly detection and root cause analysis
