Topic 1, Knowledge-Based Section A Question #:1 - (Exam Topic 1) A Tableau Cloud client has requested a custom dashboard to help track which data sources are used most frequently in dashboards across their site.

Which two actions should the client use to access the necessary metadata? Choose two.

A. Connect directly to the Site Content data source within the Admin Insights project.

B. Query metadata through the GraphiQL engine.

C. Access metadata through the Metadata API. D. Download metadata through Tableau Catalog.

Answer: B C

Explanation To track which data sources are used most frequently across a site in Tableau Cloud, the client should use the GraphiQL engine and the Metadata API.The GraphiQL engine allows for interactive exploration of the metadata, making it easier to construct and test queries1.The Metadata API provides access to metadata and lineage of external assets used by the content published to Tableau Cloud, which is essential for tracking data source usage2.

References:The actions are based on the capabilities of the GraphiQL engine and the Metadata API as described in Tableau’s official documentation and learning resources321.

Question #:2 - (Exam Topic 1) A new Tableau user created a simple dashboard on Tableau Server using supply chain data. Now, the user wants to know if they created the dashboard in accordance with specific performance best practices.

Which approach should the consultant recommend for the client to make this determination?

A. Use inbuilt dashboards in Tableau Server to troubleshoot the performance.

B. Use Performance Recording on Tableau Server.

C. Use Performance Recording in Tableau Desktop.

D. Run Workbook Optimizer.

Explanation The Workbook Optimizer is a tool specifically designed to evaluate a workbook against performance best practices. It provides feedback on key design characteristics and offers concrete guidance on how to improve workbook performance.This tool is beneficial for both new and experienced Tableau users to ensure their dashboards are optimized for performance1.

References:The Workbook Optimizer’s functionality is detailed in Tableau’s official documentation, which explains how it assesses workbooks against a set of rules derived from best practices1.Additionally, the Performance Recording feature in Tableau Desktop and Server can be used to identify performance issues, but the Workbook Optimizer gives a more comprehensive analysis of the workbook’s adherence to best practices23.

Question #:3 - (Exam Topic 1) A client wants to see the average number of orders per customer per month, broken down by region. The client has created the following calculated field: Orders per Customer: {FIXED [Customer ID]: COUNTD([Order ID])} The client then creates a line chart that plots AVG(Orders per Customer) over MONTH(Order Date) by Region. The numbers shown by this chart are far higher than the customer expects.

The client asks a consultant to rewrite the calculation so the result meets their expectation.

Which calculation should the consultant use?

A. {INCLUDE [Customer ID]: COUNTD([Order ID])} B. {FIXED [Customer ID], [Region]: COUNTD([Order ID])} C. {EXCLUDE [Customer ID]: COUNTD([Order ID])} D. {FIXED [Customer ID], [Region], [Order Date]: COUNTD([Order ID])} Answer: B

Explanation The calculation{FIXED [Customer ID], [Region]: COUNTD([Order ID])}is the correct one to use for this scenario. This Level of Detail (LOD) expression will calculate the distinct count of orders for each customer within each region, which is then averaged per month. This approach ensures that the average number of orders per customer is accurately calculated for each region and then broken down by month, aligning with the client’s expectations.

References:The LOD expressions in Tableau allow for precise control over the level of detail at which calculations are performed, which is essential for accurate data analysis.The use of{FIXED}expressions to specify the granularity of the calculation is a common practice and is well-documented in Tableau’s official Verified Solution - 100% Result

resources12.

The initial calculation provided by the client likely overestimates the average number of orders per customer per month by region due to improper granularity control. The revised calculation must take into account both the customer and the region to correctly aggregate the data: FIXED Level of Detail Expression: This calculation uses a FIXED expression to count distinct order IDs for each customer within each region. This ensures that the count of orders is correctly grouped by both customer ID and region, addressing potential duplication or misaggregation issues.

Accurate Aggregation: By specifying both [Customer ID] and [Region] in the FIXED expression, the calculation prevents the overcounting of orders that may appear if only customer ID was considered, especially when a customer could be ordering from multiple regions.

References: Level of Detail Expressions in Tableau: These expressions allow you to specify the level of granularity you need for your calculations, independent of the visualization's level of detail, thus offering precise control over data aggregation.

Question #:4 - (Exam Topic 1) A client is using the Tableau Content Migration Tool to move content from an old Tableau Server to a new Tableau Server.

Which content will need to be moved using a different tool or process?

A. Published data sources that use live connections B. Tableau Prep flows C. Published data sources that use extracts D. Workbooks Answer: B

Explanation When migrating content between Tableau servers, certain types of content may require special consideration or different tools for migration: Tableau Prep Flows: These are specific to Tableau Prep and are not included in the standard content migration capabilities of the Tableau Content Migration Tool. Tableau Prep flows often require separate processes for migration due to their distinct setup and integration with data sources and workflows.

Published Data Sources and Workbooks: These can typically be migrated directly using the Tableau Content Migration Tool, which supports moving published data sources (both live connections and extracts) and workbooks without requiring additional tools.

method. Here’s how you can apply it: In Tableau Prep, drag your dataset into the flow.

Click on theOrderldfield in the workspace to select it.

Look for the option in the toolbar that says "Split" and select it.

Choose "Automatic Split" if the delimiters (such as hyphens) are consistent; Tableau Prep should automatically detect the hyphen as the delimiter and split theOrderldinto multiple new fields.

The dataset should now show new columns: one for the country code (CA, FR, US), one for the year (2017), and one for the order number (152156, 152157, etc.).

The Split option works effectively here because it automatically identifies and uses the hyphen as the delimiter to divide the originalOrderldinto the desired components without manual specification of conditions or writing any formulas.

ReferencesThis procedure is based on the standard functionalities provided in Tableau Prep for splitting a field into multiple columns based on a delimiter, as described in the Tableau Prep user guide.
