The Open Group Architecture Framework (TOGAF) Practice Exam

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

1. Application interoperability

2. Information interoperability

3. Presentation interoperability

4. Technical interoperability

The correct answer is: Presentation interoperability

The definition of interoperability in TOGAF emphasizes the capacity to share information and services across different systems and platforms. Presentation interoperability specifically refers to how different systems present information to the user in a consistent and unified manner. This includes using a common look-and-feel approach, which ensures that users have a seamless experience when interacting with various applications and services through a single interface or portal. By employing a common portal-like solution, presentation interoperability effectively enhances user engagement and minimizes confusion, as users can easily navigate through different systems without adjusting to varying interfaces. This is essential in environments where multiple applications may be accessed simultaneously, as it allows for a coherent user experience, enhancing productivity and satisfaction. Other categories of interoperability focus on different aspects. For instance, application interoperability deals with the interactions between software applications themselves; information interoperability is concerned with the sharing and understanding of data between different systems; and technical interoperability emphasizes the underlying technologies and protocols that enable systems to communicate. While these aspects are crucial, presentation interoperability is specifically about how users perceive and interact with those systems, making it the correct answer to the question.
