QUESTION: 11 Exam Topic: 1, Knowledge-Based Section A

A client builds a dashboard that presents current and long-term stock measures. Currently, the data is at a daily level. The data presents as a bar chart that presents monthly results over current and previous years. Some measures must present as monthly averages.

What should the consultant recommend to limit the data source for optimal performance?

Limit data to current and previous years and leave data at daily level to calculate the averages in the report.
Limit data to current and previous years, move calculating averages to data layer, and aggregate dates to monthly level.
Move calculating averages to data layer and aggregate dates to monthly level.
Limit data to current and previous years as well as to the last day of each month to eliminate the need to use the averages.

Answer(s): B

Explanation:

For optimal performance, it is recommended to limit the data to what is necessary for analysis, which in this case would be the current and previous years. Moving the calculation of averages to the data layer and aggregating the dates to a monthly level will reduce the granularity of the data, thereby improving the performance of the dashboard. This approach aligns with best practices for optimizing workbook performance in Tableau, which suggest simplifying the data model and reducing the number of records processed.

Reference:

The recommendation is based on the guidelines provided in Tableau's official documentation on optimizing workbook performance, which includes tips on data management and aggregation for better performance.

QUESTION: 12 Exam Topic: 1, Knowledge-Based Section A

A consultant builds a report where profit margin is calculated as SUM([Profit]) / SUM([Sales]). Three groups of users are organized on Tableau Server with the following levels of data access that they can be granted.

. Group 1: Viewers who cannot see any information on profitability . Group 2: Viewers who can see profit and profit margin . Group 3: Viewers who can see profit margin but not the value of profit

Which approach should the consultant use to provide the required level of access?

Use user filters to access data on profitability to all groups. Then, create a calculated field that allows visibility of profit value to Group 2 and use the calculation in the view in the report.
Specify in the row-level security (RLS) entitlement table individuals who can see profit, profit margin, or none of these. Then, use the table data to create user filters in the report.
Use user filters to allow only Groups 2 and 3 access to data on profitability. Then, create a calculated field that limits visibility of profit value to Group 2 and use the calculation in the view in the report.
Specify with user filters in each view individuals who can see profit, profit margin, or none of these.

Answer(s): C

Explanation:

The approach of using user filters to control access to data on profitability for Groups 2 and 3, combined with a calculated field that restricts the visibility of profit value to only Group 2, aligns with Tableau's best practices for managing content permissions. This method ensures that each group sees only the data they are permitted to view, with Group 1 not seeing any profitability information, Group 2 seeing both profit and profit margin, and Group 3 seeing only the profit margin without the actual profit values. This setup can be achieved through Tableau Server's permission capabilities, which allow for detailed control over what each user or group can see and interact with.

Reference:

The solution is based on the capabilities and permission rules that are part of Tableau Server's security model, as detailed in the official Tableau documentation. These resources provide guidance on how to set up user filters and calculated fields to manage data access levels effectively.

QUESTION: 13 Exam Topic: 1, Knowledge-Based Section A

A company has a data source for sales transactions. The data source has the following characteristics:

. Millions of transactions occur weekly.
. The transactions are added nightly.
. Incorrect transactions are revised every week on Saturday.
· The end users need to see up-to-date data daily.

A consultant needs to publish a data source in Tableau Server to ensure that all the transactions in the data source are available.

What should the consultant do to create and publish the data?

Publish an incremental extract refresh every day and perform a full extract refresh every Saturday.
Publish a live connection to Tableau Server.
Publish an incremental refresh every Saturday.
Publish an incremental extract refresh every day and publish a secondary data set containing data revisions.

Answer(s): A

Explanation:

Given the need for up-to-date data on a daily basis and weekly revisions, the best approach is to use an incremental extract refresh daily to update the data source with new transactions. On Saturdays, when incorrect transactions are revised, a full extract refresh should be performed to incorporate all revisions and ensure the data's accuracy. This strategy allows end users to have access to the most current data throughout the week while also accounting for any necessary corrections.

Reference:

The solution is based on best practices for managing data sources in Tableau Server, which recommend using incremental refreshes for frequent updates and full refreshes when significant changes or corrections are made to the data.

QUESTION: 14 Exam Topic: 1, Knowledge-Based Section A

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.

Connect directly to the Site Content data source within the Admin Insights project.
Query metadata through the GraphiQL engine.
Access metadata through the Metadata API.
Download metadata through Tableau Catalog.

Answer(s): 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 queries. 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 usage.

Reference:

The actions are based on the capabilities of the GraphiQL engine and the Metadata API as described in Tableau's official documentation and learning resources.

QUESTION: 15 Exam Topic: 1, Knowledge-Based Section A

A client wants to report Saturday and Sunday regardless of the workbook's data source's locale settings.

Which calculation should the consultant recommend?

DATEPART('weekday', [Order Date])>=6
DATEPART('iso-weekday', [Order Date])>=6
DATENAME('iso-weekday', [Order Date])>=6
DATEPART('iso-weekday', [Order Date])=1 or DATEPART('iso-weekday', [Order Date])=7

Answer(s): D

Explanation:

The calculation DATEPART('iso-weekday', [Order Date])=1 or DATEPART('iso-weekday', [Order Date])=7 is recommended because the ISO standard considers Monday as the first day of the week (1) and Sunday as the last day (7). This calculation will correctly identify Saturdays and Sundays regardless of the locale settings of the workbook's data source, ensuring that the report includes these days as specified by the client.

Reference:

The use of the `iso-weekday' part in the DATEPART function is consistent with the ISO 8601 standard, which is independent of locale settings. This approach is supported by Tableau's documentation on date functions and their behavior with different locale settings.

To accurately identify weekends across different locale settings, using the 'iso-weekday' component is reliable as it is consistent across various locales:
ISO Weekday Function: The ISO standard treats Monday as the first day of the week (1), which makes Sunday the seventh day (7). This standardization helps avoid discrepancies in weekday calculations that might arise due to locale-specific settings.
Identifying Weekends: The calculation checks if the 'iso-weekday' part of the date is either 1 (Sunday) or 7 (Saturday), thereby correctly identifying weekends regardless of the locale settings.

Handling Locale-Specific Settings: Using ISO standards in date functions allows for uniform results across systems with differing locale settings, essential for consistent reporting in global applications.
