A. 平均
B. カウント
C. 中央値

A. ディスクリートです
B. 連続です
C. 寸法です
D. 目安です

正解：A

解説：
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.

質問 # 28

A. 52,678 および 311,404
B. 1,807 および 34,571
C. 5,129 と 88,872
D. 4,888 と 17,817

正解：D

解説：
To reach the correct answer, follow these steps:
1) Drag Order Date (Discrete Year) to the Column shelf, and Region to the Row Shelf as shown:

2) Drag Profit to Text in the Marks Shelf as shown:

3) Click on Analysis as shown -> Totals -> SELECT ROW GRAND TOTALS
The following will be the final view:

You could also Filter by Region to only Focus on Canada, but that's your choice:

THEREFORE,
2012 = 4,888
2011 -> 2014 = 17,817

質問 # 30
次のフィルターが表示されている場合は、_______________________ を使用しています。拡大画像

A. 日付関数
B. 日付パーツ
C. グループ化された日付
D. 日付値

正解：D

解説：
Dates in Tableau will behave differently depending on whether they are a Datepart (blue) or a Datevalue (green). This affects how the axes display/behave and also how visualisations such as line charts will display. The difference essentially boils down to Dateparts behaving like a dimension as opposed to a measure which is how Datevalues behave. This means that Dateparts behave like discrete categories on the view whereas Datevalues are more like continuous numeric values.
Dateparts are discrete and they behave the same as dimension filters. If all dates are used on the filter then each individual date will be a datepart that can be selected/excluded. This is the same for each level of date, if datepart months is placed on filters January to December will be tick-able options in the filter. This also means that conditions and top/bottom filters can be applied to datepart filters like any other dimension filter.
Datevalues placed on filters behave like measure filters. A min and a max date can be set and there is a relative dates option which allows you to choose things like only show the previous 3 months or years etc.

質問 # 31
次の点のうち、Viz アニメーションについて正しいものはどれですか?

A. ワークブック全体で一度にオンにすることができます
B. アニメーションは、Web のマップ、ポリゴン、および密度マークでうまく機能します。
ブラウザ
C. シーケンシャルアニメーションは時間がかかりますが、複雑な変更を行います
段階的に提示することでより明確に
D. 特定のワークシートでのみオンにできます

正解：A、C、D

解説：
All of the given options are true except - Animations work well with maps, polygons, and density marks in web browsers.
From the official documentation:

As seen above, we can either turn the animations for the entire workbook (upper red box), or only for the current sheet ( lower red box )
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.

質問 # 32
ビューに Car Dropoff City という名前のフィールドを含む、都市ごとのレンタカー統計を表示するダッシュボードがあります。ダッシュボードの URL アクションは、URL ターゲットとして https://en.wikipedia.org/wiki/<Car Dropoff City> を使用します。
ビュー内でソルトレイクシティをクリックすると、URL アクションによってどこに移動しますか?

A. https://en.wikipedia.org/wiki/<ソルトレイクシティ>
B. https://en.wikipedia.org/wiki/Salt.LakeXity
C. https://en.wikipedia.org/wiki/Salt+Lake+City+Car+Dropoff+City
D. https://en.wikipedia.org/wiki/<車の返却都市>

正解：C

解説：
When you click Salt Lake City in the view, the URL action will direct you to https://en.wikipedia.org/wiki/Salt+Lake+City+Car+Dropoff+City. A URL action is a hyperlink that points to a web page or other web-based resource outside of Tableau. You can use URL actions to create an email or link to additional information about your data. To customize links based on your data, you can automatically enter field values as parameters in URLs3 In this case, the URL action uses https://en.wikipedia.org/wiki/<Car Dropoff City> as the URL target, where <Car Dropoff City> is a field value from the view. When you click Salt Lake City in the view, Tableau will replace <Car Dropoff City> with Salt Lake City in the URL target. However, since spaces are not allowed in URLs, Tableau will encode them as + signs instead. Therefore, the final URL will be https://en.wikipedia.org/wiki/Salt+Lake+City+Car+Dropoff+City3 The other options are not correct because they do not reflect how Tableau encodes field values in URL actions.

質問 # 33
あるテーブルから別のテーブルに値 (行) を追加することで、データを ________________ 2 つ以上のテーブルを組み合わせることができます

A. 連結
B. ブレンド
C. ユニオン
D. 参加

正解：C

解説：
You can union your data to combine two or more tables by appending values (rows) from one table to another.
To union your data in Tableau data source, the tables must come from the same connection.
For example, suppose you have the following customer purchase information stored in three tables, separated by month. The table names are "May2016," "June2016," and "July2016."

A union of these tables creates the following single table that contains all rows from all tables.

質問 # 34
____________ 並べ替えの場合、データがどのように変化しても、値は常に保持した並べ替え順序のままになります。

A. 階層
B. トポロジカル
C. マニュアル
D. ランダム

正解：C

解説：
For a manual sort, no matter how the data changes, the values will always stay in the sort order you kept stuff in.
From the official website:

質問 # 35
一般的なベストプラクティスとして、円グラフに効果的に表示できるカテゴリの数はいくつですか?

A. 2 ～ 8
B. 3 ～ 7
C. 3 ～ 5
D. 2 ～ 5

正解：D

解説：
As a general best practice, your pie chart should contain 2 to 5 categories. Anything more than that is not easy for the eyes to distinguish. This is a common question and mentioned in Tableau's own eLearning module as well!
See how to build a pie chart:

質問 # 36
連続フィルターで使用できる 2 つのフィルターモードはどれですか? 2 つ選択してください。

A. 値の範囲
B. 単一の値
C. 複数の値
D. スペシャル

正解：A、D

解説：
According to the Tableau Help, there are two filter modes for continuous filters: Range of Values and Single Value. The help also states that "Range of Values lets you specify a minimum and maximum value for the filter using sliders or input fields" and "Single Value lets you select one value on a slider for the filter" (page
1).

質問 # 37
巨大なデータセットを扱っている場合、コンテキストフィルターを使用する強い理由は次のうちどれですか?

A. コンテキストフィルターを依存フィルターにするには
B. データのクリーンアップに役立ちます
C. 目的のデータのみを含める場合
D. クエリのパフォーマンスを向上させる

正解：C、D

解説：
By default, all filters that you set in Tableau are computed independently. That is, each filter accesses all rows in your data source without regard to other filters. However, you can set one or more categorical filters as context filters for the view. You can think of a context filter as being an independent filter (Option stating - To create a dependent filter eliminated here). Any other filters that you set are defined as dependent filters because they process only the data that passes through the context filter.
You may create a context filter to:
1) Improve performance - If you set a lot of filters or have a large data source, the queries can be slow. You can set one or more context filters to improve performance.
2) Create a dependent numerical or top N filter - You can set a context filter to include only the data of interest, and then set a numerical or a top N filter.
For example, suppose you're in charge of breakfast products for a large grocery chain. Your task is to find the top 10 breakfast products by profitability for all stores. If the data source is very large, you can set a context filter to include only breakfast products. Then you can create a top 10 filter by profit as a dependent filter, which would process only the data that passes through the context filter.

_________________ は、オフラインで作業し、パフォーマンスを向上させる必要がある場合に、他のユーザーとデータを共有するために使用できるサブセットまたはデータセット全体のローカルコピーです。

A. .tbm ファイル
B. .tde ファイル
C. .twbx ファイル
D. .twb ファイル

正解：B

解説：
According to the official Tableau documentation:
Depending on the version the extract was created in, Tableau extract files can have either the .hyper or .tde file extension. Extract files are a local copy of a subset or entire data set that you can use to share data with others, when you need to work offline, and improve performance. For more information, see Extract Your Data.

質問 # 39

質問 # 40
次のうち、日付部分の例はどれですか?

A. 2020 年 9 月
B. 2019年3月
C. 11月
D. 2017 年第 4 四半期

正解：C

解説：
All answers except November are examples of Date Values (continuous in nature).
See below:

You can see that the option in Green symbolizes our correct answer, i.e only a Month. In our case that month is November (the correct answer).
All other options are combinations of a year with one other value (like a month, quarter, or day). So this is how by looking at an option you can know if its a date part or date value!
