Which of the following are categories of integration types in ServiceNow?

The selected answer encompasses three fundamental categories that are essential for effectively integrating various functionalities within ServiceNow. Authentication is crucial as it establishes secure access to systems, ensuring that only authorized users can interact with sensitive data and applications. Next, data integrations facilitate the transfer and synchronization of data between ServiceNow and other external systems, which is vital for maintaining data consistency and integrity across different platforms. Lastly, web services represent a method for services to communicate over the web, allowing for seamless interactions between different applications, either within or outside the ServiceNow ecosystem.

This selection highlights the importance of security, data management, and communication processes in building an effective integrative framework within ServiceNow. The other options incorporate terms that, while relevant to integration discussions, do not collectively represent the essential categories as thoroughly as this answer does. For instance, terms like 'user management' or 'APIs' are too narrow or specific to encompass the broader integration categories that cover authentication, data exchange, and web-based services.
