Question #6
What are two characteristics of relationships? (Choose two.)
  1. A
    Relationships will query every table in a data model regardless of whether the fields are in the visualization.
  2. B
    Relationships will query only the tables and fields needed to create a visualization.
  3. C
    Relationships are only supported when using extracts.
  4. D
    Relationships are aware automatically of the native level of detail of logical tables.

Correct Answer:
BC

The correct assertion that relationships in Tableau query only necessary tables and fields aligns with their optimized performance feature. They are designed to efficiently handle data by loading only what's needed for specific visualizations, enhancing response times and reducing load on the database. Moreover, contrary to option C, relationships do support both live connections and extracts, not just extracts, as pointed out in user discussions. This distinction is crucial for understanding the flexible and dynamic nature of data handling in Tableau.

Question #7
What are two examples of a date value? (Choose two.)
  1. A
    January 1, 1995
  2. B
    December
  3. C
    Wednesday
  4. D
    2020-05-01

Correct Answer:
AD

For the provided question, options A and D correctly represent examples of date values because they specify complete and specific points in time with associated day, month, and year. Partial or general time components like just a month or a day of the week do not qualify as complete date values.

Question #8
What are three reasons to use joins instead of relationships? (Choose three.)
  1. A
    You need to use a specific join type.
  2. B
    You need to create an extract that will have multiple tables.
  3. C
    You need to use row-level security.
  4. D
    You need to use a data model that supports shared dimensions.
  5. E
    You need to connect to multiple databases.

Correct Answer:
ACE
chatbot-img GPT-4o - Answer
When considering the use of joins in Tableau, key reasons include the necessity to use specific join types and implementing row-level security, as joins allow for data manipulation and restrictions at this granular level. Additionally, while joins and relationships can both connect to multiple databases, the decision to use a join might stem from the need for these specific configurations which relationships might not support similarly. Thus, opting for joins can be critical for certain specific data handling requirements in your visualizations or analytics setup.

Question #9
What are three benefits of using an extract as compared to a live connection to a data source? (Choose three.)
  1. A
    A live connection to a data source provides the best performance for data connections.
  2. B
    Calculated fields perform better in workbooks connected to extracts than in workbooks with live connections to a data source.
  3. C
    Extracts are stored in memory (RAM), resulting in faster query performance as compared with live data connections.
  4. D
    An extract reduces the amount of data stored on a client computer as compared to a live data connection.
  5. E
    A live connection to a data source can be slow due to network and user traffic, whereas a connection to an extract improves performance.

Correct Answer:
BCE

Extracts in Tableau offer significant performance enhancements over live connections due to the data being stored in memory, which allows for quicker access and processing. This is particularly beneficial when dealing with large datasets. Additionally, extracts improve calculated field performance and provide reliable visualization performance regardless of network traffic, which can affect live connections. Thus, opting for an extract can vastly increase efficiency in data handling and analysis.

Question #10
How can you access options to apply bold formatting to an axis in the view?
  1. A
    Select Text on the Marks card.
  2. B
    Select Field Labels on the Format menu.
  3. C
    Right-click on the Field and select Format.
  4. D
    Right-click on the axis.

Correct Answer:
B
chatbot-img GPT-4o - Answer
To apply bold formatting to an axis in Tableau, the most straightforward approach is indeed selecting Field Labels from the Format menu. This method opens the Format pane directly where you can adjust the font style, including bold, for all field labels associated with axes in your view. This is a central location for all text formatting options, providing a more intuitive and unified control compared to other methods which might not directly impact the axis labels.
