Tableau TCA-C01 Exam Questions

Reviewing and optimizing the database queries used in Tableau workbooks for efficiency The first course of action when dealing with slow query response times from external databases, as indicated by a performance recording, should be to review and optimize the database queries used in Tableau workbooks. Optimizing queries can include simplifying them, reducing the amount of data queried, or improving the structure of the queries. This directly addresses the inefficiencies in the queries, potentially improving response times without the need for major infrastructure changes. Option A is incorrect because upgrading external database servers is a more resource-intensive solution and should be considered only if query optimization is not sufficient. Option C is incorrect as implementing caching mechanisms might alleviate some issues but does not address the root cause of slow query performance. Option D is incorrect because restricting the size of data ex-tracts does not necessarily improve the efficiency of the queries themselves.

Implementing SCIM for automated user provisioning and deprovisioning SCIM allows for automated and efficient management of user accounts in a dynamic workforce, handling changes in employment status and roles without manual intervention. Option A is incorrect because manual account management is inefficient and prone to errors in a large, dynamic organization. Option C is incorrect as using a shared account compromises security and does not provide individual user accountability. Option D is incorrect because it disperses the responsibility and can lead to in-consistent account management practices.

A high-performance server cluster with load balancing and a high-speed net-work to manage the large number of concurrent users For an enterprise with widespread operations and high concurrency, a robust server cluster and a high-speed network are crucial to handle the load and ensure smooth operation without performance bottlenecks. Option A is incorrect because a minimal setup would likely lead to performance issues given the large number of users. Option C is incorrect as standard hardware might not suffice for the demands of a large global enterprise. Option D is incorrect because focusing solely on storage without considering network speed and load balancing can lead to significant performance issues.

The Tableau Server performance logs that include information on server processes and resource usage When diagnosing performance issues with Tableau Server on Linux, the Tableau Server performance logs are most useful. These logs provide information on server processes, resource usage, and potential bottlenecks in server performance. Analyzing these logs can help identify specific areas that are impacting the overall performance of Tableau Server. Option A is in-correct because authentication logs are primarily used for security auditing and are less likely to pro-vide insights into performance issues. Option C is incorrect as boot logs are useful for startup issues but not typically for ongoing performance problems. Option D is incorrect because while database logs can provide insights into database performance, they are not the first resource to check for general performance issues with Tableau Server.

Use a dedicated service account with restricted permissions for repository access Utilizing a dedicated service account with restricted permissions is crucial for maintaining security while accessing an external repository. This ensures that Tableau Server interacts with the repository in a controlled manner, reducing the risk of unauthorized access or data breaches. Option A is incorrect because allowing anonymous access compromises security and is not recommended for external repositories. Option B is incorrect as a direct VPN connection, while secure, is not a necessary step for configuring an external repository in Tableau Server. Option C is incorrect because repository partitioning based on user roles and permissions is not a standard feature or requirement for Tableau Server's external repository configuration.
