Which of the following services is an example of a SOAP service?

A SOAP (Simple Object Access Protocol) service is a protocol used for exchanging structured information in web services. It is based on XML and is commonly used for enabling communication between applications over the internet.

The weather service is a classic example of a SOAP service because it typically requires requesting and retrieving data in a structured format. Such services often provide well-defined operations and use XML in their communication, making them suitable for SOAP standards. An example is a weather API that allows applications to request current conditions or forecasts in a standardized way, leveraging the verbosity and structure of XML that SOAP requires.

In contrast, the other options generally utilize different protocols or data formats. Google Search and Facebook services tend to rely more on RESTful APIs, which use lightweight data formats like JSON, allowing for easier and more flexible interactions. Online Games also typically do not expose their communication via SOAP services, focusing instead on performance optimizations and real-time data exchange methods.
