質問 # 36
Tableauで視覚化するための軸はいつ作成されますか？
- A. メジャーを行/列シェルフにドラッグするとき
- B. 離散フィールドを行/列シェルフにドラッグするとき
- C. 連続フィールドを行/列シェルフにドラッグするとき
- D. ディメンションを行/列シェルフにドラッグするとき
正解：C
解説：
Explanation
An Individual Axis in Tableau is obtained by adding a continuous into Rows or Columns Shelf.
Example:
In order to show Individual Axis in Tableau First, we drag and drop the Color from Dimension shelf to Column Shelf. Next, we drag and drop the Sales Amount from measures shelf to Rows Shelf. Since it is a continuous value, the Sales Amount will be aggregated to default Sum. Once you drag them, following Chart report will be generated.
Next, we drag and Drop one more measure value, i.e., Total Product Cost from Measures Region to Rows Shelf. Because it is a Measure value, Total Product Cost is aggregated to default Sum. From the below screenshot, you can observe that Tableau has created an individual axis for each measure (continuous field).
質問 # 37
正誤問題：近似曲線は数値フィールドまたは日付フィールドでのみ使用できる
- A. 本当
- B. 偽
正解：B
解説：
Explanation
You can show trend lines in a visualization to highlight trends in your data.
To add trend lines to a view, both axes must contain a field that can be interpreted as a number. For example, you cannot add a trend line to a view that has the Product Category dimension, which contains strings, on the Columns shelf and the Profit measure on the Rows shelf.
However, you can add a trend line to a view of sales over time because both sales and time can be interpreted as numeric values.
質問 # 38
正誤問題：データを分解して、ビュー内のすべてのマークを最も詳細なレベルで表示することができる
- A. 本当
- B. 偽
正解：A
解説：
Explanation
Whenever you add a measure to your view, an aggregation is applied to that measure by default. This default is controlled by the Aggregate Measures setting in the Analysis menu.
If you decide you want to see all of the marks in the view at the most detailed level of granularity, you can disaggregate the view. Disaggregating your data means that Tableau will display a separate mark for every data value in every row of your data source.
To disaggregate all measures in the view:
Clear the Analysis >Aggregate Measures option. If it is already selected, click Aggregate Measures once to deselect it.
質問 # 39
_____________は、Tableauがローカルに保存するデータのスナップショットです。必要なフィールドが少ない非常に大きなデータセットに適しています。
- A. Tableauデータ抽出（.tde）
- B. Tableauワークブック（.twb）
- C. Tableauパッケージワークブック（.twbx）
- D. Tableauデータソース（.tds）
正解：A
解説：
Explanation
Tableau Data Extract (TDE) is a snapshot of the data that Tableau stores locally. Good for very large datasets of which we only need few fields. Performance is optimised because it queries its own database engine instead of the local data source.
When you create an extract of your data, you can reduce the total amount of data by using filters and configuring other limits. After you create an extract, you can refresh it with data from the original data. When refreshing the data, you have the option to either do a full refresh, which replaces all of the contents in the extract, or you can do an incremental refresh, which only adds rows that are new since the previous refresh.
Extracts are advantageous for several reasons:
1) Supports large data sets: You can create extracts that contain billions of rows of data.
2) Fast to create: If you're working with large data sets, creating and working with extracts can be faster than working with the original data.
3) Help improve performance: When you interact with views that use extract data sources, you generally experience better performance than when interacting with views based on connections to the original data.
4) Support additional functionality: Extracts allow you to take advantage of Tableau functionality that's not available or supported by the original data, such as the ability to compute Count Distinct.
5) Provide offline access to your data: Extracts allow you to save and work with the data locally when the original data is not available. For example, when you are traveling.

These FIELDS are also referred to as PILLS. See below:
質問 # 41
正誤問題：セットはメジャーで作成できる
- A. 本当
- B. 偽
正解：B
解説：
Explanation
Sets are custom fields that are created within Tableau Desktop based on dimensions from your data source.
They are subsets of your data, which can be created manually or computed. Either dimensions or measures can be used to determine what is included or excluded from a set using conditional logic, but to CREATE a set we use dimensions.

質問 # 42
可変サイズのビンを作成するには、__________________を使用します
- A. テーブルの計算
- B. 計算フィールド
- C. セット
- D. グループ
正解：B
解説：
Explanation
One way to view a measure in Tableau Desktop is to split it into bins. You can think of bins as buckets based on a range of values. For example, say you have a measure that represents age. Instead of aggregating the measure to calculate the average age, you can bin the measure to define age groups: 0-5, 6-10, 11-15, and so on. Then you can count the number of people in each age group.
Create a calculated field for variable bin size
Step 1
Select Analysis > Create Calculated Field.
Step 2
In the Calculated Field dialog box, complete the following steps:

質問 # 47
データセットを使用して、地域ごとに分類された平均数量を示す棒グラフを作成し、国ごとにフィルタリングして日本のみを表示します。東京州の平均数量はいくらでしたか？
- A. 3.840
- B. 3.500
- C. 3.704
- D. 3.000
正解：C
解説：
Explanation
Since we need to focus on 1 country -> Japan, let's filter on it first as follows:
1) Drag Country to the filter shelf, and choose only Japan. Click OK.
2) Read the Question Carefully, we need to break down the visualisation by Region, then by Country, and then by State. So let's do that:
Drag Region to the column shelf, followed by Country. Drill down into Country to include states as well.
Then drag Quantity to the Row Shelf, and change the Aggregation to AVERAGE.
The following is our visualisation:
Now that you think of it, EVEN IF YOU REMOVE THE REGION, THE ANSWER REMAINS THE SAME.
Such elements will be present in the actual exam too, just to make the question sound a little difficult, but actually it is pretty straightforward :)
質問 # 48
Tableauの__________________を使用して、データをクリーンアップ/整理できます。
- A. データクリーナー
- B. データマネージャー
- C. データインタプリタ
- D. データオーガナイザー
正解：C
解説：
Explanation
When you track data in Excel spreadsheets, you create them with the human interface in mind. To make your spreadsheets easy to read, you might include things like titles, stacked headers, notes, maybe empty rows and columns to add white space, and you probably have multiple tabs of data too.
When you want to analyze this data in Tableau, these aesthetically pleasing attributes make it very difficult for Tableau to interpret your data. That's where Data Interpreter can help.
質問 # 49
2016年の米国の平均住宅価格を示すフィールドはおそらく次のとおりです。
- A. 地理的次元
- B. 集計されたメジャー
- C. 連続日付値ディメンション
- D. 離散日付パーツディメンション
正解：B
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".

Tableauのビューのマークに色を追加するにはどうすればよいですか？
- A. 上のメインメニューの[データ]をクリックし、[色の選択]をクリックします。
- B. 列/行のシェルフで、フィールドを右クリックし、[シェルフで編集]をクリックして色を選択します。
- C. [データ]ペインで、フィールドを[マーク]カードの[色]にドラッグします。
- D. [分析]ペインから、モデルを[マーク]カードの[色]にドラッグします。
正解：C
解説：
Explanation
To assign a color to marks in the view, do the following:
From the Data pane, drag a field to Color on the Marks card.
Tableau applies different colors to marks based on the field's values and members. For example, if you drop a discrete field (a blue field), such as Category, on Color, the marks in the view are broken out by category, and each category is assigned a color.
If you drop a continuous field, such as SUM(sales), on Color, each mark in the view is colored based on its sales value.
質問 # 52
Tableau Desktopの有効な公式データソースではないものは次のうちどれですか？
- A. PostgreSQL
- B. Google Firebase
- C. SAP HANA
- D. Amazon Redshift
正解：D
解説：
Explanation
Presently, there is no official way to connect your data in Firebase directly with Tableau Desktop.
A workaround however can be to export your Firebase data into Google BigQuery, and then connect it to Tableau Desktop.
But then again, it is a workaround and not an official out-of-the-box solution.
The following are the available Data sources available as of now:
* Server
* File

解説：
Explanation
Exporting the visualisation gives us a static view of the visualisation.
It is NOT possible to interact with it, use filters, or dynamically enter anything in a visualisation exported PDF.
In Tableau Desktop, you can save views as PDF files rather than printing them as hard copies. You do not need to have Adobe Acrobat installed on your computer.
When you print an individual sheet to PDF, filters in the view are not included. To show filters, create a dashboard containing the sheet and export the dashboard to PDF. (IMPORTANT)

- A. 利益、州、レコード数、売上高
- B. 経度、国、州、売上高
- C. 地域、国、利益、州
- D. 売上高、州、国、利益
正解：D
解説：
Explanation
Since Sales is a measure, it can easily be depicted via size.
To drill down and change the level of detail, Country is the correct choice since it will contain STATE. We can then depict the various states by different shapes such as circle, square etc.
Finally, the Profit can be depicted via a color! Eg - Red for poor and green for excellent profits!
質問 # 57
Tableauのストーリーポイントにダッシュボードとワークシートの両方を同時に追加することは可能ですか？
- A. いいえ
- B. はい
正解：A
解説：
Explanation
This is a tricky question. We are talking about story POINTS, and not entire stories in the question.
To create a story, lets say I have a blank story with 1 dashboard and 1 worksheet.
I can simply drag the dashboard into the view to create a new story point.
Now, if I try to adjust the worksheet beside it in this same view, I cannot. See below:
The only option available is to replace the existing view. Therefore, the answer is NO since they both cannot be added.
