Tableau TCA-C01 Tableau Certified Architect Exam Practice Test

Answer : C

To provide seamless user experience during upgrades or maintenance The primary purpose of maintaining two identical environments in a blue-green deployment is to ensure a seamless user experience during upgrades or maintenance. This approach allows for one environment (blue) to be active while the other (green) is updated or maintained. Users are then switched over to the updated environment with minimal disruption. Option A is incorrect because using one environment for development and the other for production is not the primary goal of blue-green deployment, which focuses on seamless transitions during updates. Option B is incorrect as A/B testing is not the main objective of blue-green deployment, which is more about minimizing downtime and ensuring service continuity. Option D is incorrect because dividing the workload between servers is not the fundamental purpose of this strategy; rather, it's about having a ready-to-go, updated environment.

Answer : B

Checking the web proxy settings for any bandwidth limits or filtering rules that might be affecting performance When facing slow performance issues with Tableau Server accessed via a web proxy, the initial step should be to check the web proxy settings. Look for any bandwidth limits, filtering rules, or other configurations that might be impeding the data flow and affecting performance. Adjusting these settings can often resolve performance issues related to proxy use. Option A is incorrect as disabling the web proxy might not be feasible due to organizational policies and does not directly address the root cause. Option C is incorrect because reinstalling Tableau Server is an excessive step before checking proxy settings. Option D is incorrect as changing the port used by Tableau Server might not be feasible or effective in addressing performance issues related to proxy settings.

Answer : B

The 'data_connections' table to gain insights into connections and performance of published data sources The 'data_connections' table in the Tableau repository schema is critical for tracking the performance of published data sources. It provides detailed information on each connection made to the data sources, offering insights into how these data sources are being accessed and utilized, which is crucial for understanding and optimizing their performance. Option A is incorrect because the 'users' table, while identifying users, does not provide specific information on data source performance. Option C is incorrect as the 'background_tasks' table focuses on scheduled tasks and does not offer detailed insights into real-time data source performance. Option D is incorrect because the 'server_usage' table provides a broad overview of server activity but does not offer the granular details required for monitoring specific data source performance.

Answer : B

The average load time of views on the server Including the metric of average load time of views on a Tableau Server administrative dashboard is crucial for effectively tracking server health. This metric provides insights into the server's performance and user experience, high-lighting potential issues or bottlenecks in view rendering that could affect overall server efficiency. Option A is incorrect because the number of published workbooks, while informative, does not directly indicate server health or performance. Option C is incorrect as the total number of registered users does not provide immediate insight into the current performance or health of the server. Option D is incorrect because the frequency of extract refreshes, while important for data freshness, does not directly reflect server performance in terms of view load times.

Answer : B

Obtaining and installing a valid SSL certificate from a trusted certificate authority A critical step in implementing SSL encryption for Tableau Server is to obtain and install a valid SSL certificate from a trusted certificate authority. This ensures that the communication be-tween the server and clients is encrypted and secure. Using a certificate from a trusted authority al-so helps in avoiding trust issues with clients connecting to the server. Option A is incorrect because a self-signed SSL certificate might not be trusted by all clients and can lead to security warnings. Option C is incorrect as enabling HTTP does not contribute to SSL encryption; instead, HTTPS should be used. Option D is incorrect because disabling firewalls can compromise the overall security of the server and is not necessary for SSL implementation.

Answer : B

The Tableau Server log files, especially the ''tabadmin.log'' and ''tabsvc.log'' files When facing startup issues with Tableau Server on a Windows system, the Tableau Server log files, particularly ''tabadmin.log'' and ''tabsvc.log,'' should be reviewed first. These logs can provide detailed insights into the startup process and highlight any errors or issues that are preventing the server from starting correctly. Option A is incorrect because antivirus logs, while useful for checking interference with program files, are not the primary source for diagnosing startup issues with Tableau Server. Option C is incorrect as SQL Server logs are more relevant for database-related issues and may not provide specific details on Tableau Server startup problems. Option D is incorrect be-cause user access logs generally do not contain information relevant to system startup issues.

Answer : A

Setting appropriate thresholds and alerts for system performance metrics in RMT When configuring RMT for Tableau Server, it is vital to set appropriate thresholds and alerts for system performance metrics. This ensures that administrators are notified of potential issues or resource bottlenecks, allowing for timely intervention and maintenance to maintain optimal server performance. Option A is incorrect as monitoring user login and logout activities is not the primary function of RMT; its focus is on server performance and resource usage. Option C is incorrect be-cause while integrating with external network monitoring tools can provide additional insights, it is not essential for the basic functionality of RMT. Option D is incorrect as integrating RMT with the user database for user analytics is beyond the scope of its intended use, which is focused on system performance monitoring.
