Which process is installed along with the first instance of Application Server on a node?

The correct answer is Interactive Container Service. When you install the first instance of the Application Server on a node, it's essential for the system to manage user interactions seamlessly. The Interactive Container Service is specifically designed for handling requests and processes that require real-time interactions, such as user sessions and application-related activities.

This service is crucial for maintaining the responsiveness and efficiency of the Application Server, which plays a vital role in delivering interfaces to users and managing their interactions with the hosted applications. By integrating this service with the first installation, Tableau ensures that the node is fully equipped to support the dynamic nature of user-driven data visualizations and interactions.

In contrast, other processes such as the Non-Interactive Container Service or the Coordination Service serve different functions within the ecosystem of the Tableau environment. The Non-Interactive Container Service is more related to background processing and batch tasks rather than direct user interaction, while the Coordination Service relates to orchestration across nodes and helps manage state and communication, rather than focusing on the immediate needs of user sessions. Lastly, Database Maintenance is an ongoing process for upkeep and optimization of databases, rather than a component that installs directly with the Application Server.
