- B . It is identified by a green pill in a visualization
- C . It is preceded by a ‘=#’ symbol in the data window
- D . It is preceded by a ‘Abc’ symbol in the data window
B
Explanation:
When you connect to a new data source, Tableau assigns each field in the data source as dimension or measure in the Data pane, depending on the type of data the field contains. You use these fields to build views of your data.

Which chart type uses automatically generated sizes that cannot be resized by using the Marks card?
- A . Packed bubbles
- B . Side-by-side circles
- C . Heat maps
- D . Density map
A
Explanation:
In Tableau, a Density map (also known as a heat map) uses automatically generated sizes for the data points that cannot be resized by using the Marks card. This chart type is designed to display density of data points on a map, where the size and color of the data points represent the concentration of data in that area.
You have the following legend.
What occurs when you click the icon to the right of Air Ticketing Cabin Type Name?
- A . The filter options open.
- B . The legend toggles on or off.
- C . The highlighter toggles on or off.
- D . The Edit Colors dialog box opens
C
Explanation:
When you click the icon to the right of Air Ticketing Cabin Type Name, the highlighter toggles on or off. The highlighter is a feature that allows you to highlight marks in the view that match a specific value or condition. You can access the highlighter by clicking the icon next to a dimension or measure in the legend, filter, or parameter. The icon looks like a light bulb with a plus sign. When you click the icon, a highlighter box will appear where you can enter or select a value to highlight. The marks that match the value will be highlighted in the view, while the others will be dimmed. You can also use the highlighter box to search for values, clear the highlighting, or lock the highlighting. To turn off the highlighter, you can click the icon again or close the highlighter box. The other options are not correct descriptions of what occurs when you click the icon to the right of Air Ticketing Cabin Type Name. The filter options do not open, because the icon is not for filtering, but for highlighting. The legend does not toggle on or off, because the icon is not for showing or hiding the legend, but for accessing the highlighter. The Edit Colors dialog box does not open, because the icon is not for changing the colors of marks, but for highlighting them.
Using the dataset, plot a Map showing all the countries, filtered by Market to only include LATAM.
Which country in the LATAM Market has the highest shipping delay (sum of total number of days between the order date and the ship date)?
- A . Brazil
- B . Peru
- C . Argentina
- D . Mexico
D
Explanation:
VERY IMPORTANT QUESTION FOR THE EXAM, PAY ATTENTION
1) To find the number of days between order date and shipping date, we will make use of a calculated field:
In the data pane, click on the dropdown arrow, and choose create calculated field.
Let’s name this calculated field "ShippingDelay" (you can name it anything you want 🙂 )
2) Use the DATEDIFF() function, and pass it the arguments as follows:
‘day’ depicts that we want to calculate the number of DAYS between the two dates. The first argument is ‘start_date’ which is the ORDER_DATE (day the order was placed), the second argument is ‘end_date’, which is the SHIP_DATE (date the order was shipped). So by subtracting as follows: SHIP_DATE – ORDER_DATE, we can find the delay in shipping.
Click OK.
3) You should now have a new measure as follows:
4) Phew! The hard part is done! Now let’s filter by Market to include only LATAM:
5) Drag Country to the view, and the new calculated field ‘ShippingDelay’ to SIZE on the Marks Shelf as follows:
*You can also click on Show Text Labels to be sure that you’re choosing the Largest value*
Clearly, Mexico has the highest Shipping Delay!
Is it possible to make a Measure discrete?
- A . No
- B . Yes
B
Explanation:
Of course! Follow along:
Right click on any measure, and choose Discrete as shown:
Once you do this, the green pill becomes blue in colour, indicating that it is now Discrete!

2) The median is marked by a vertical line inside the box
3) The whiskers are the two lines outside the box that extend to the highest and lowest observations.
You have the following visualization.
Where should you place a field named Region to show multiple distinct lines on the same axis?
- A . Path on the Marks card
- B . Color on the Marks card
- C . The Columns shelf
- D . The Rows shelf
B
Explanation:
To display multiple distinct lines on the same axis based on a field, you should place the field on the Color shelf in the Marks card. This will encode each distinct value in the Region field with a different color, resulting in separate lines for each region on the same axis.
