NEW QUESTION # 23
You have a dashboard that contains confidential information about patients health. The data needs to always be up to date tor a team of healthcare workers How should you share me dashboard with the healthcare workers?
- A. Export the dashboard as a .twbx
- B. Publish the dashboard to Tableau Server
- C. Publish the dashboard to Tableau Public
- D. Print the dashboard to PDF
Answer: B
Explanation:
To share a dashboard that contains confidential information about patients health and needs to always be up to date for a team of healthcare workers, you should publish it to Tableau Server. This will allow you to control who can access and interact with your dashboard, as well as schedule automatic refreshes of your data source or extract. Publishing to Tableau Public would expose your data to anyone on the internet, printing to PDF would not update your data, and exporting as a .twbx would require sending a large file that might not be compatible with other versions of Tableau.

When sharing sensitive and confidential information that needs to be kept up-to-date, such as patient health data for a team of healthcare workers, the best practice is to publish the dashboard to Tableau Server. Tableau Server is designed for secure, controlled access and can be configured to ensure that data is refreshed as needed. Publishing to Tableau Public is not secure for confidential data, printing to PDF or exporting as a .
twbx does not allow for live data updates.
NEW QUESTION # 24
You publish a dashboard that uses an extract. The extract refreshes every Monday at 10:00.
You need to ensure that the extract also refreshes on the last day of the month at 18:00.
What should you do?
- A. From Tableau Server, select the workbook, select Refresh Extracts, and then add a new extract refresh.
- B. From Tableau Desktop, open the Publish Workbook dialog box and configure the schedule.
- C. From Tableau Server, select Schedules, find the schedule of the extract, and change the frequency to the last day of the month.
- D. From Tableau Server, select Schedules, and change the priority of the existing schedule.
Answer: A
Explanation:
To ensure that the extract also refreshes on the last day of the month at 18:00, you need to add a new extract refresh task to the workbook on Tableau Server. You can do this by selecting the workbook, selecting Refresh Extracts, and then choosing Schedule a Refresh. You can then select an existing schedule that matches your desired frequency and time, or create a new schedule with a custom frequency and time. This will add a new extract refresh task to the workbook, in addition to the existing one that refreshes every Monday at 10:00. You can also modify or delete the extract refresh tasks as needed.

You need each record to alternate between grey and white.
What should you change in the Format Shading pane?
- A. the row banding size to 3
- B. the column banding size to 1
- C. the row banding size to 1
- D. the column banding size to 3
Answer: C
Explanation:
To have each record alternate between grey and white, you should change the row banding size to 1 in the Format Shading pane. This setting will ensure that each row has a different shading from the one above and below it, creating an alternating pattern of grey and white rows. References: The answer can be verified through practical application within Tableau or by consulting Tableau's official learning resources, such as Tableau Help: Format Shading or Tableau Training Pass: Formatting.
NEW QUESTION # 29
You have a data source that has two tables named Table1 and Table2. Table1 is the primary table and Table2 is the secondary table.
You want to combine the tables by using Tableau Prep. The combined table must include only values from Table1 that do NOT match any values in Table2. The field values from Table2 must appear as null values.
Which type of join should you use?
- A. Inner
- B. Union
- C. Left only
- D. Full outer
- E. Left
Answer: C
Explanation:
To combine the tables by using Tableau Prep and include only values from Table1 that do not match any values in Table2, you should use a left only join. A left only join is a type of join that returns only the rows from the primary table (Table1) that have no matching rows in the secondary table (Table2). The field values from Table2 will appear as null values in the combined table. A left only join is also known as an anti-join or an exclusion join. References:
Tableau Certified Data Analyst Exam Prep Guide, page 9, section "Preparing Data" Tableau Help: Join Your Data Tableau Help: Left Only Join
NEW QUESTION # 30
You connect to a database server by using Tableau Prep. The database server has a data role named Role1.
You have the following field in the data.
You need to apply the Role1 data role to the Material field.
Which two actions should you perform? Choose two.
- A. From the More actions menu of Materials, filter the selected values.
- B. From the More actions menu of Materials, select Valid in the Show values section.
- C. From the More actions menu of Materials, select Group Values, and then select Spelling.
- D. For the data type of the Material field, select Custom, and then select Role1.
Answer: C,D
Explanation:
To apply a custom data role to a field, you need to select the data type of the field and then choose the data role from the list of available roles. This will validate the values in the field against the data role and mark any invalid values with a red exclamation mark. To fix the invalid values, you can use the Group Values option and select the Spelling algorithm, which will group values that are close in spelling and replace them with the most frequent value in the group. This will help you standardize the values in the Material field and match them with the Role1 data role. References: The information is based on the following sources:
* Use Data Roles to Validate your Data - Tableau
* New in Tableau Prep: Automatically identify data quality issues with Data Roles
NEW QUESTION # 31
You need to change the values of a dimension without creating a new field.
What should you do?
- A. Create aliases
- B. Create groups
- C. Rename the fields
- D. Transforms the fields
Answer: A
Explanation:
You can create aliases for the members of a dimension by right-clicking the dimension in the Data pane or in the view and selecting Aliases. This changes how the values are displayed in the view, but not the underlying data. For example, you can create an alias for "Central" as "Midwest".

NEW QUESTION # 34
You have the following two datasets:
* A Microsoft Excel worksheet that has two columns named Employee Name and Department
* A Microsoft SQL Server table that has three columns named Employee Name. Pay Grade and Team Size.
You want to use Tableau Prep to join the two datasets.
Which three actions should you perform in order? (Place the three correct options in order.)
Answer:
Explanation:
Explanation:
The correct order of the three actions is:
From the connections pane, connect to both data sources
Join both datasets and select the join type
Specify Employee Name as the join key
The first action is to connect to both data sources from the connections pane in Tableau Prep. The connections pane is where you can access and add data sources to your flow. You can connect to various types of data sources, such as Excel, SQL Server, or Tableau Server. In this case, you want to connect to an Excel worksheet and a SQL Server table.
The second action is to join both datasets and select the join type. A join is a way of combining data from two or more tables based on a common field. You can join datasets by dragging one table to the canvas and dropping it on top of another table. This will create a join step in your flow. You can select the join type from the drop-down list on the join step. The join type determines which rows are returned from the tables.
The third action is to specify Employee Name as the join key. A join key is a field that is used to match rows from different tables. You can specify the join key by clicking on the field name in each table and dragging it to the center of the join step. This will create a join clause that shows the field name and the operator. In this case, you want to use Employee Name as the join key, because it is a common field between the two datasets.
The other options are not relevant for this scenario. Specifying Department and Team Size as a join condition will not work, because they are not common fields between the two datasets. Opening both data sources in Tableau Desktop will not help you join them in Tableau Prep. Adding a step to aggregate the data in the SQL Server table will not affect the join, but it may change the level of detail of your data. References:

NEW QUESTION # 36
You have a blank dashboard.
You want to add two sheets to the dashboard. The sheets must support the Show/Hide button.
To which two objects can you add the sheets? (Click the two appropriate Options in the Answer Area.)
Answer:
Explanation:
To add two sheets to the dashboard that support the Show/Hide button, you can add them to either a horizontal or a vertical container. A container is an object that can hold one or more sheets or other objects and allow you to arrange them in a layout. A Show/Hide button is a feature that lets you hide or show a container and its contents on the dashboard. You can add a Show/Hide button to any container, whether it is tiled or floating, by using the drop-down menu of the container and selecting "Add Show/Hide Button." You can also customize the appearance and behavior of the button.
To add a horizontal or a vertical container to the dashboard, you can drag them from the Objects pane to the dashboard. A horizontal container will arrange the sheets or objects horizontally, while a vertical container will arrange them vertically. You can then drag the sheets you want to add from the Sheets pane to the container. You can resize and reorder the sheets or objects within the container by using the handles and arrows.
The other objects in the Answer Area, such as text, image, web page, blank, navigation, download, and extension, do not support the Show/Hide button. They are either static elements that cannot hold other objects, or dynamic elements that require user interaction or external sources. You can add them to the dashboard as well, but they will not have the same functionality as a container with a Show/Hide button.

You have the following line chart that shows the average sales by month.
Which month had the biggest increase in swage sales compared to me previous month in 2019?
- A. December
- B. October
- C. November
- D. August
Answer: B
Explanation:
To find the month that had the biggest increase in average sales compared to the previous month in 2019, you need to compare the slopes of the line segments between each pair of months. The steeper the slope, the greater the increase. Based on the line chart, October had the steepest slope, meaning it had the biggest increase in average sales compared to September in 2019.
