質問 # 40
Which of the following is NOT a new feature introduced in Tableau 2020.1?
- A. Viz Animations
- B. Dynamic Paramaters
- C. Set Control
- D. Buffer Calculations
正解：C
解説：
Explanation
Your Tableau Desktop Specialist exam will be based on the 2020.1 version.
Set controls are a new feature introduced in the 2020.2 version, and hence is the correct answer - it is not a part of 2020.1 For the 2020.1 version the new features were:
1) Viz animations:
Viz animations help you see and understand your changing data. It's easy to track the logical steps behind data's evolution and tell powerful data stories. Sorting, filtering, adding fields, and other actions will now smoothly animate your visualizations. Choose whether to turn Viz Animations on or off, and decide how you'd best like to apply animations to your new workbooks.
2) Dynamic Parameters:
Say goodbye to republishing workbooks with parameters every time the underlying data changes. Set your parameter once, and Tableau will automatically update the parameter's list of values every time someone opens the workbook.
3) Buffer Calculations:
Buffer calculations allow you to visualize the distance around point locations. Give Tableau three parameters-location, distance, and a unit of measure-and a buffer, or boundary is instantly created.
Answering complex spatial questions becomes easier than ever before-visualize what properties are within
200 meters of a proposed transit site, or how many competitors' stores are within 1 mile of their store, and more.

質問 # 42
Using the Time Series table, create a cross-tab showing sales for each Assortment broken down by Year and Quarter. In Q4 of October 2017, what was the Average sales amount for the Hardware assortment?
- A. 112,256
- B. 1,461
- C. 111,060
- D. 1,222
正解：A
解説：
Explanation
If you chose 111,060 you were SO close to the correct answer but made a small mistake - you didn't change the aggregation to AVERAGE! This is one of the common mistakes many test takers make, so keep this in mind.
To reach the correct answer, follow the steps below:
1) Draw Assortment to the Column shelf, and drag Year to the Rows Shelf. Then Drill down further on Year to accomodate Quarters and Months as well!
Although this seems enough, DON'T FORGET to change the aggregation like in the next step, which will completely change the values!
* The correct answer as you can see is 1,461 - Sales for Harware Assortment in 2017 Q4, October
質問 # 43

2) But, this isn't all right? We need to focus on the year 2013. This can be done by using the year column as it is (continuous) in the filter shelf, or by converting it to discrete first and then using it:
2.1 As it is (continuous)
2.2 Converting to discrete first & then using it
and then :
3) We can now see that France, with 485 has the 2nd most number of patents for the year 2013

質問 # 48
Are animations enabled by default in Tableau?
- A. No
- B. Yes
正解：A
解説：
Explanation
No, by default, animations are not enabled in Tableau.
We can animate visualizations to better highlight changing patterns in your data, reveal spikes and outliers, and see how data points cluster and separate.
Animations visually transition between filter, sort, and zoom settings, different pages, and changes to filter, parameter, and set actions. As visualizations animate in response to these changes, viewers can more clearly see how data differs, helping them make better informed decisions.
When you author animations, you can choose between two different styles: simultaneous or sequential. Here are examples of each type.
1) Simultaneous animations
The default simultaneous animations are faster and work well when showing value changes in simpler charts and dashboards.
2) Sequential animations
Sequential animations take more time but make complex changes clearer by presenting them step-by-step.
To Animate visualizations in a workbook:
1) Choose Format > Animations.
2) If you want to animate every sheet, under Workbook Default, click On. Then do the following:
For Duration, choose a preset, or specify a custom duration of up to 10 seconds.
For Style, choose Simultaneous to play all animations at once or Sequential to fade out marks, move and sort them, and then fade them in.
3) To override workbook defaults for a particular sheet, change the settings under Selected Sheet.
質問 # 49
A field that shows average home values for the United States in 2016 is most likely :
- A. A continuous date value dimension
- B. A discrete date part dimension
- C. A geographical dimension
- D. An aggregated measure
正解：D
解説：
Explanation
This question is directly from the Official Tableau Desktop Specialist exam guide.
Since we are talking about the AVERAGE home values for the United States in 2016, the question is directly offering us a hint that the answer has something to do with aggregation and that too the values tell us that we're working with MEASURES.
Date part and Date values don't really make much sense given the question, and neither does geography.
Therefore, the answer naturally is "An aggregated measure".
質問 # 50
