Chartered Property Casualty Underwriter (CPCU) 500 Practice Exam

Which one of the following best describes the function of the service layer of a smart operation?

Transmitting data without human interaction Employing applications that use data processing, cloud computing, and storage and analysis of large amounts of data Using sensors, cameras, and data-collection capabilities to provide information to others Transmitting data using wireless protocols that ensure necessary capabilities

Correct Answer:

Employing applications that use data processing, cloud computing, and storage and analysis of large amounts of data

Explanation:

In a smart operation, the service layer is where applications run that turn raw data into usable insights. It involves data processing, storage, and analysis—leveraging cloud computing and the ability to handle large volumes of data to produce dashboards, reports, and decision-support tools. That is exactly what the described option conveys: applications that use data processing, cloud storage, and analysis of large data sets. The other descriptions map to different layers: using sensors and data-collection capabilities corresponds to the sensing layer, while transmitting data (without human intervention or via wireless protocols) aligns with the network/communication layer.
