Tableau TCA-C01 Tableau Certified Architect Exam Practice Test

Answer : C

Tailoring the process count to balance between VizQL, Data Server, and Back-grounder based on expected usage and demand Customizing the process count to reflect the organization's specific usage patterns ensures optimal performance without over-allocating resources, which is crucial for a medium-sized business. Option A is incorrect because over-allocating processes can be resource-intensive and unnecessary for moderate usage. Option B is incorrect as it does not account for the specific needs and usage patterns of the business. Option D is incorrect because it overlooks the importance of balancing different process types for a well-rounded performance.

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

Using cron jobs to schedule and execute backup scripts at regular intervals On a Linux system, cron jobs are the recommended method for deploying automated backup scripts for Tableau Server. Cron allows for the precise scheduling of scripts to run at regular intervals, ensuring consistent and automated backups without the need for manual initiation. Option A is incorrect be-cause the Tableau Server web interface does not provide a mechanism for automating server-level scripts like backups. Option C is incorrect as relying solely on a third-party cloud service for back-ups does not address the need for local script automation and management. Option D is incorrect because manual initiation is not efficient for regular maintenance tasks like backups.

Answer : B

Employing tabcmd to schedule and execute extract refreshes at specified inter-vals Tabcmd is a highly effective tool for automating extract refreshes on Tableau Server. It can be used to schedule and execute extract refreshes at regular, specified intervals, ensuring that the data remains up-to-date without requiring manual intervention each time. Option A is incorrect because webhooks are typically used for event-driven actions and are less suited for regularly scheduled tasks like extract refreshes. Option C is incorrect as the Hyper API is more focused on creating and updating extracts, not on scheduling their refreshes. Option D is incorrect because relying on manual refreshes is time-consuming and not feasible for consistent data updates in a large-scale environment.

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

Running the Installation Wizard as an administrator to ensure sufficient privileges for setup When installing Tableau Server on Windows, it is crucial to run the Installation Wizard as an administrator. This ensures that the installer has the necessary privileges to access system resources and configure settings required for the successful installation of Tableau Server. Option A is incorrect because while antivirus or firewall software can sometimes interfere with installations, it's not recommended to disable all security software as a first step. Option C is incorrect as automatically updating system drivers during the installation is not a standard requirement for installing Tableau Server. Option D is incorrect because setting up a dedicated virtual machine is not a requirement for installing Tableau Server, though it can be an option based on organizational policies.

Answer : B

Moderate-capacity server with reliable network connectivity, adequate for small team collaboration For a small team of 20 analysts, a moderate-capacity server with reliable network connectivity provides a balanced and cost-effective solution, ensuring good performance without over-investing in unnecessary high-end infrastructure. Option A is incorrect because enterprise-grade infrastructure is excessive for a small team and may not be cost-effective. Option C is incorrect as the highest available specifications may be overkill for a small consulting firm and not a financially prudent choice. Option D is incorrect because consumer-grade hardware and a standard residential internet connection may not provide the reliability and performance needed for professional Tableau use.
