Tableau Server Interview Questions & Answers
1. What is data visualization?
Data visualization is the process of converting data into an understandable graphic format. It can be done using a variety of formats, including graphs, maps, and charts. Data trends, outliers, and patterns are found using data visualization.
2. List the file extensions in Tableau.
Table contains various file types and extensions. A few of these are:
3. Can the interactor publish the visualizations? What are the various site roles available in a Tableau server?
The following list includes the various roles that can be found on the Tableau server:
No, an interactor cannot be able to publish the visualizations.
4. What is the disadvantage of context filters?
The user does not frequently change the Context Filter. The database must be recomputed in the event that the Filter is changed, and the temporary table must be updated. This process slows down the performance.
Tableau creates a temporary table when we set a dimension to context, which requires a reload each time the view is launched.
5. How many maximum tables can you join in Tableau?
In Tableau, we can join a maximum of 32 tables.
6. How do you configure Alerts in the Tableau server? What is an Alert?
If the Tableau server goes down, Alert will automatically send you an email with the server’s status. An SMTP (Simple Mail Transfer Protocol) server is required in order to configure the Alerts on the Tableau server.
7. What is a Choropleth Map?
Depending on a data variable, a choropleth map is used to display divided geographic areas that are colored, shaded, or patterned. It is utilized to identify patterns across the displayed location by visualizing values over a geographical area.
8. What is SSL, and how do we configure SSL?
SSL is the short form for Secured Socket Layer. SSL encrypts the data before sending it over the network to protect it from unauthorized access. SSL will automatically decrypt the data once it reaches the intended recipient.
To configure the SSL, we need an SSL certificate file. This certificate file can be obtained from a third-party hosting company like NORTON.
9. Explain the limitations of the parameters of Tableau.
On a dashboard, the parameters of Tableau can only be displayed in four different ways. Additionally, these parameters forbid any additional multiple selections in a filter.

Using the NOW() function in Tableau, we can obtain the current date and time.

To ensure that Tableau takes action on information pieces, a shelve is a place in the visualization display. Headers are produced for the members when a dimension is added to the shelves of the rows or columns.
In Tableau, we have four kinds of shelves:
14.What is the difference between data blending and join?
Join is a SQL operation that unites two data sources into a single data source. While the Tableau term “blending” is used to describe combining two data sources into a readily available chart
The fact that a join is applied once at the data source and used for all charts, whereas a blend is applied individually for each chart, is a key distinction between these two terms.
15.What is the Tableau Data Engine?
One of Tableau’s fantastic features is the Tableau data engine. It is an analytical database created to provide immediate response to queries, predictive performance, and seamless integration with current data infrastructure.
Making indexes, importing data, and sorting it take some time when working with a lot of data, but after that, the process goes quickly. Once imported, the data is stored on disk, and RAM is barely used.

17.What is Assume Referential Integrity?
Each row in the certainty table in a database has a corresponding combination row in the measurement table. To join the tables, we use this technique to create primary and foreign keys.
We inform Tableau that the joined tables have referential integrity by using the Assume Referential Integrity command. In more straightforward terms, we confirm that the Dimension table will consistently contain a row that coordinates with the table.
18.Why do we use the mark card in Tableau?
The Mark card is a crucial component of Tableau’s visual inspection. Setting and information are added to the view marks when fields are dragged to various Marks card properties.
Later, we can set the mark as write and encode our information using size, color, text, shape, and details using the Marks Card.
