Tableau TCA-C01 Exam Questions

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.

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.

Ensuring that WDCs are securely accessing data sources and handling data transfer securely and efficiently When configuring web data connectors on Tableau Server, it is essential to ensure that these connectors access data sources securely and handle data transfer efficiently. This involves verifying the security of the data source connections and ensuring that data handling by the WDCs adheres to best practices for data security and integrity. Option A is incorrect because it is not necessary for all WDCs to be hosted on the same server as Tableau Server. Option B is incorrect as updating WDCs without proper testing and compatibility checks can lead to issues with data accuracy or security. Option D is incorrect because while internal connectors may offer certain security assurances, prohibiting all third-party connectors can unnecessarily limit functionality and innovation.

Isolating critical services like Data Server and Repository on separate nodes, while collocating less critical services Isolating critical services enhances security and performance, especially for a financial institution, while collocating less critical services can optimize resource us-age and management. Option A is incorrect because isolating all services may lead to underutilization of resources and increased complexity. Option B is incorrect as collocating all services on a single node can create a single point of failure and performance bottlenecks. Option D is incorrect be-cause a strategic approach is necessary for efficient and secure service-to-node relationships.
