When the Physical Tables option is selected for an extract in Tableau, an individual table is created for each physical table in the extract. This means that the extract will include a separate table for each underlying table in your database, maintaining the database's structure within the extract. This can be useful when you need to preserve the original granularity of the data or when working with certain database optimizations.

To create a packaged data source (.tdsx file) in Tableau, you would right-click on the data connection in the Data pane and select the option to add it to saved data sources. This action packages the data source with the metadata that you've defined in Tableau, such as calculations, groups, and sets, so that you can easily share it with others. This does not package the data itself, which is a separate step if you're working with local file-based data.

Hierarchies in Tableau are used to define a drill-down path through your data. By creating a hierarchy, you can organize related fields together, which makes it easier to navigate complex data models. This also allows users to explore data at different levels of detail, from the highest level of the hierarchy to the most granular details, simply by clicking to expand and collapse levels of the hierarchy in the view.

To provide additional information when hovering over a field in the Data pane, as shown in the exhibit, you need to configure a default comment for the field. This comment can be set by right-clicking on the field in the Data pane and selecting 'Default Properties' and then 'Comment.' The text entered as a comment here will then be displayed as a tooltip when hovering over the field in the Data pane.

To display your company's web page on a Tableau dashboard, you should use a web page object. The web page object allows you to embed a web page within your Tableau dashboard, providing direct access to external web content.

Open your Dashboard: Start by opening the dashboard where you want to add the web page.

Add Web Page Object: In the Objects section of the dashboard pane, select the 'Web Page' object and drag it onto your dashboard.

Configure URL: After placing the web page object, a dialog box will prompt you to enter the URL of the web page you want to display. Enter your company's web page URL here.

Resize and Position: Adjust the size and position of the web page object to fit your dashboard design.

Continuous fields in Tableau have specific characteristics:

A . Continuous fields appear as green pills:

Continuous fields in Tableau are represented as green pills in the view. This indicates that they are treated as a continuous range of values rather than discrete categories.

B . Continuous fields are numeric:

Continuous fields typically consist of numeric data that can take any value within a range. They are used to measure and compare data values.

C . The values in continuous fields are treated as an infinite range:

Continuous fields are treated as an infinite range, allowing for detailed and granular analysis of data. Unlike discrete fields, which are considered distinct and separate, continuous fields are seen as a seamless continuum.

Incorrect options:

D . Continuous fields are categorical: This is incorrect because categorical fields are discrete, not continuous.

E . Only measures can appear as continuous: This is incorrect because dimensions can also be treated as continuous in certain contexts.

Visualization animations in Tableau can highlight changing patterns in data and can be either simultaneous or sequential:

A . Highlights changing patterns in data:

Visualization animations are designed to highlight changes in data over time or as filters are applied. They help users to see how data trends and patterns evolve.

B . Can be simultaneous or sequential:

Animations in Tableau can be configured to play simultaneously or sequentially. Simultaneous animations play all changes at once, while sequential animations play changes one after the other, allowing for a step-by-step view of data transformations.

Incorrect options:

C . Can be applied to map visualizations: While animations can be applied to map visualizations, the statement is not one of the two correct descriptions of visualization animations as per the question context.

D . Uses the Pages shelf: The Pages shelf is used for creating page animations, which is a different concept from visualization animations.
