Simulating a variety of user activities, such as viewing dashboards, publishing workbooks, and refreshing extracts A comprehensive load testing strategy for Tableau Server should include simulating a variety of user activities. This includes tasks like viewing dashboards, publishing workbooks, and refreshing extracts. This approach ensures a thorough evaluation of the server's performance across different types of demands and user interactions, providing a more realistic assessment of its capabilities and limitations. Option A is incorrect because testing with only a single dashboard does not account for the varied activities users perform on the server. Option C is incorrect as focusing solely on data source connection speeds neglects other crucial aspects of server performance. Option D is incorrect because running tests only with administrative users does not replicate the typical activities of regular users, which are essential for understanding the server's performance under normal operating conditions.
