QUESTION: 21 Exam Topic: 1, Knowledge-Based Section A

A client has a published data source in Tableau Server and they want to revert to the previous version of the data source. The solution must minimize the impact on users.

What should the consultant do to accomplish this task?

Request that a server administrator restore a Tableau Server backup.
Delete and recreate the data source manually.
Select a previous version from Tableau Server, download it, and republish that data source.
Select a previous version from Tableau Server, and then click Restore.

Answer(s): D

Explanation:

To minimize the impact on users when reverting to a previous version of a published data source in Tableau Server, the consultant should use the built-in revision history feature. By selecting a previous version from the revision history and clicking `Restore', the data source will revert to that version without the need for a full server backup restoration or manual recreation of the data source. This process is quick and has the least amount of disruption to users.

Reference:

The functionality and process for reverting to a previous version of a data source are outlined in Tableau's official documentation on working with content revisions. This feature is part of Tableau Server's capabilities to manage and maintain data sources effectively.

QUESTION: 22 Exam Topic: 1, Knowledge-Based Section A

A client is using Tableau to visualize data by leveraging security token-based credentials. Suddenly, sales representatives in the field are reporting that they cannot access the necessary workbooks. The client cannot recreate the error from their offices, but they have seen screenshots from the field agents. The client wants to restore functionality for the field agents with minimal disruption.

Which step should the consultant recommend to accomplish the client's goal?

Ensure that "Allow Refresh Access" was checked when the data source was published.
Change the data source permissions for the connection to "Prompt User."
Ask the workbook owners to republish the workbooks to refresh the security token.
Renew the security token via the Data Connection on Tableau Server.

Answer(s): D

Explanation:

When field agents are unable to access workbooks due to issues with security token-based credentials, the most immediate and least disruptive solution is to renew the security token. This can be done through the Data Connection settings on Tableau Server. Renewing the token will restore access for the field agents without requiring them to take any action or affecting other users.

Reference:

The use of personal access tokens (PATs) in Tableau and the procedure for renewing them are documented in Tableau's official resources. It is noted that PATs are long-lived authentication tokens that can be revoked and renewed to manage access securely. Additionally, there have been discussions in the Tableau Community regarding issues with concurrent PAT access, which further supports the need to manage tokens effectively.

QUESTION: 23 Exam Topic: 1, Knowledge-Based Section A

For a new report, a consultant needs to build a data model with three different tables, including two that contain hierarchies of locations and products. The third table contains detailed warehousing data from all locations across six countries. The consultant uses Tableau Cloud and the size of the third table excludes using an extract.

What is the most performant approach to model the data for a live connection?

Relating the tables in Tableau Desktop
Blending the first two tables with the third
Joining the tables in Tableau Prep
Joining the tables in Tableau Desktop

Answer(s): A

Explanation:

For a performant live connection in Tableau Cloud, especially when dealing with large datasets that preclude the use of extracts, relating the tables in Tableau Desktop is the recommended approach. This method allows for flexibility in how the data is queried and can improve performance by leveraging Tableau's relationships feature, which optimizes queries for the underlying database.

Reference:

The best practices for live connections in Tableau Cloud suggest using relationships to manage complex data models efficiently. Additionally, Tableau's documentation on connecting data sources recommends using relationships for better performance with live connections.

QUESTION: 24 Exam Topic: 1, Knowledge-Based Section A

A client is considering migrating from Tableau Server to Tableau Cloud.

Which two elements are determining factors of whether the client should use Tableau Server or Tableau Cloud? Choose two.

Whether or not the client plans to leverage single sign-on (SSO)
Whether or not there are large numbers of concurrent extract refreshes
Whether or not the client needs the ability to connect to public, cloud-based data sources
Amount of data storage used on the client's existing server

Answer(s): A,B

Explanation:

When considering a migration from Tableau Server to Tableau Cloud, two critical factors to consider are the client's need for single sign-on (SSO) and the volume of concurrent extract refreshes. Single Sign-On (SSO): Tableau Cloud supports SSO, which can streamline user authentication and enhance security. If the client plans to leverage SSO, Tableau Cloud may be a suitable choice. Concurrent Extract Refreshes: The number of concurrent extract refreshes is a significant factor because it impacts performance and resource allocation. Tableau Server might be more appropriate if the client has a high volume of concurrent extract refreshes, as it allows for more control over the infrastructure to manage these workloads.

Reference:

The decision between Tableau Server and Tableau Cloud should be based on specific organizational needs, including security, compliance, performance, and scalability. The official

Tableau resources provide guidance on these factors. Additionally, discussions in the Tableau Community highlight the importance of considering these elements when choosing between Tableau Server and Tableau Cloud.
