You have an Internet of Things (loT) device that monitors engine temperature. The device generates an alert if the engine temperature deviates from…

The scenario describes a system that identifies data points (engine temperatures) that fall outside of a normal, expected range. This process of identifying rare events or observations that differ significantly from the majority of the data is the core function of an anomaly detection workload. This capability is frequently used in predictive maintenance for equipment, such as monitoring engine temperatures from an IoT device to detect potential failures before they occur.

A. natural language processing (NLP): This workload is concerned with understanding and processing human language, such as text or speech, not numerical sensor data like temperature.

B. computer vision: This workload involves analyzing and interpreting visual information from images or videos, which is not relevant to monitoring temperature readings.

D. knowledge mining: This involves extracting information from large volumes of unstructured data to create a searchable knowledge base, not real-time monitoring of a data stream for outliers.

AI-900: Describe anomaly detection. "Anomaly detection is the process of identifying unusual patterns or outliers in data. It's a key technique in machine learning and data analysis

used in a wide range of applications

such as fraud detection

network security

and monitoring of industrial equipment."

AI-900: Introduction to anomaly detection. "For example

an IoT device on a piece of machinery might send telemetry that includes the rotation speed of a motor. If the motor's normal operating speed is between 100 and 200 revolutions per minute (RPM)

a value of 0 or 500 might indicate a potential fault. An anomaly detection model can be trained to distinguish between expected and anomalous values."
