The TOGAF standard defines interoperability as "the ability to share information and services". Which of the following categories utilizes a common look-and-feel approach through a common portal-like solution to interact with the users?

The correct answer is presentation interoperability. This category specifically focuses on how information is presented to users, ensuring that different systems and applications maintain a consistent look-and-feel across platforms. By using a common portal-like solution, presentation interoperability enhances user experience and engagement, allowing users to interact seamlessly with various services and information sources.

In this context, a common look-and-feel approach streamlines the interface and makes it easier for users to navigate different applications, regardless of the underlying technology. This enables better usability and understanding of the information shared between systems, fulfilling the overarching definition of interoperability in TOGAF.

Application interoperability involves the ability of diverse applications to work together, while information interoperability pertains to the exchange and understanding of data and content. Technical interoperability focuses on the underlying infrastructure and connectivity, ensuring that systems can communicate with each other technically. While all these aspects are essential for a holistic approach to interoperability, presentation interoperability is distinct in emphasizing the user interface and experience.
