Salesforce Updated Analytics-Arch-201 Exam Questions and Answers by aadam

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.

Simulating a variety of user activities, such as viewing dashboards, publishing workbooks, and refreshing extracts A comprehensive load testing strategy for Tableau Server should include simulating a variety of user activities. This includes tasks like viewing dashboards, publishing workbooks, and refreshing extracts. This approach ensures a thorough evaluation of the server’s performance across different types of demands and user interactions, providing a more realistic assessment of its capabilities and limitations. Option A is incorrect because testing with only a single dashboard does not account for the varied activities users perform on the server. Option C is incorrect as focusing solely on data source connection speeds neglects other crucial aspects of server performance. Option D is incorrect because running tests only with administrative users does not replicate the typical activities of regular users, which are essential for understanding the server’s performance under normal operating conditions.

The node should have more processing power and memory compared to other nodes in the deployment For optimal performance, the node dedicated to the backgrounder process should have more processing power and memory. This is because backgrounder tasks such as data extraction, subscription tasks, and complex calculations are resource-intensive and can benefit from additional computational resources. Option A is incorrect as while a fast network connection is beneficial, it is not the primary consideration for a backgrounder node, which relies more on processing power and memory. Option C is incorrect because the geographical location of the backgrounder node is less relevant than its hardware capabilities. Option D is incorrect as running a different operating system does not inherently improve the performance of the backgrounder node and may introduce compatibility issues.

Implement Tableau Bridge to establish a live connection to on-premises data-bases Tableau Bridge is specifically designed to allow real-time access to on-premises data from Tableau Cloud, making it the ideal solution for this scenario. Option A is incorrect because Tableau Prep Builder is used for data preparation, not for establishing live connections to on-premises data sources. Option C is incorrect as migrating all data to the cloud may not be feasible or desirable for all companies. Option D is incorrect because Tableau Cloud’s native capabilities do not include direct live data connections to on-premises databases without Tableau Bridge.
