During the troubleshooting of Kerberos authentication issues in Tableau Server, what is a common area to investigate?
Correct Answer:
B
The configuration of Service Principal Names (SPNs) for the Tableau Server A common area to investigate when troubleshooting Kerberos authentication issues is the configuration of Service Principal Names (SPNs) for the Tableau Server. Incorrect or incomplete SPN configuration can prevent proper authentication, as Kerberos relies on SPNs to associate service instances with service logon accounts. Option A is incorrect because while web browser compatibility is important, it is not typically the cause of Kerberos-specific issues. Option C is incorrect as network speed, while impacting overall performance, is less likely to be a direct factor in Kerberos authentication problems. Option D is incorrect because the frequency of synchronization between Tableau Server and the domain controller is not typically a factor in Kerberos authentication issues.
If a performance recording indicates that query response times from external databases are the primary bottleneck in Tableau Server, what should be the first course of action?
Correct Answer:
B
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.
