質問 # 38
Which string function returns a Boolean value as a result?
正解：D
解説：
STARTSWITH is the function that returns a Boolean result, so D is correct. The function evaluates whether one string begins with a specified substring. Its conceptual syntax is STARTSWITH(string, substring). If the original string begins with that substring, Tableau evaluates the expression as TRUE; otherwise, it evaluates as FALSE. For example, STARTSWITH([Customer Name], "A") returns TRUE for values beginning with A and FALSE for other values. Because the output is Boolean, STARTSWITH is particularly useful in calculated fields, conditional expressions, filters, classifications, and data-quality logic. The other listed functions return different data types. CHAR converts a numeric character code to its corresponding character and therefore returns a string. FIND searches for the position of a substring and returns a numeric position.
UPPER converts the supplied text to uppercase and returns another string. Consequently, only STARTSWITH directly produces the TRUE/FALSE result required by the question. This distinction is fundamental when selecting functions for Boolean calculations because Tableau evaluates Boolean fields differently from numeric and string-returning expressions.
質問 # 39
To which type of element can a Tableau associate apply a default aggregation?
正解：C
解説：
A default aggregation can be specified for a measure, making A correct. Measures represent quantitative values and are normally aggregated when they are added to a visualization. For example, a Sales measure typically appears as SUM(Sales). Tableau allows the author to change the measure's default aggregation so that subsequent uses of the field can initially use AVG, MIN, MAX, COUNT, standard deviation, or another supported aggregation instead of SUM. The configuration is available from the Data pane by right-clicking the measure and selecting Default Properties > Aggregation. The choice becomes the default behavior when the field is subsequently added to a view, although the aggregation can still be overridden for an individual instance of the field. Dimensions do not use a default measure aggregation in this manner because their primary role is to partition and categorize the data. Bins are generated categorical fields representing numerical intervals. An already aggregated calculated expression also has restrictions because Tableau cannot arbitrarily aggregate an expression that is already defined at an aggregate level. Tableau's official Default Settings documentation specifically states that users can specify a default aggregation for any measure and documents the Data pane workflow for configuring it.
質問 # 40
What are two outcomes when a Tableau associate drags a continuous date value to the Rows shelf?
正解：A、D
解説：
A continuous date field produces a green pill and generates an axis, making B and C correct. Tableau uses color as an immediate visual cue for discrete versus continuous fields. Green pills represent continuous fields, whereas blue pills represent discrete fields. A date can function in either form. When the analyst chooses a continuous date value such as continuous Month or continuous Year, Tableau represents the field as an unbroken temporal range rather than a finite collection of date-part headers. When this continuous date is placed on the Rows shelf, Tableau generates a continuous axis corresponding to the selected temporal granularity. The axis behaves similarly to other continuous quantitative axes in the sense that values occupy positions along an uninterrupted scale. Option A instead characterizes a discrete date part, such as discrete Month, where Tableau creates categorical headers or labels like January, February, and March. Option D is likewise associated with discrete fields because discrete pills are blue. Tableau's official Continuous Dates documentation states that continuous dates create an axis and that converting a date field to continuous causes the field to turn green. Tableau's general field-role documentation separately confirms that continuous fields create axes while discrete fields create headers.
質問 # 41
A Tableau associate needs to change the color intensity of a quantitative range.
Which option should the associate use?
正解：B
解説：
Opacity is the appropriate control when the objective is to change how intense or subdued the existing colors appear. In Tableau, the Color controls on the Marks card include an Opacity slider. Moving this control toward lower opacity makes marks increasingly transparent; increasing opacity makes the applied colors visually stronger and less transparent. Therefore, C is correct. The other options modify different properties.
Border adds an outline around supported mark types and does not control the overall intensity of the fill color.
Reversed inverts the ordering of a quantitative color palette-for example, changing a sequential palette so that lower values receive the darker intensity and higher values receive the lighter intensity. It changes which values receive each shade rather than controlling overall opacity. Stepped Color converts a continuous quantitative palette into a specified number of discrete color bands or bins. Tableau's current Color Palettes and Effects documentation explicitly identifies Opacity as the setting used to modify the transparency of marks. It separately defines Reversed as inverting the order of colors and Stepped Color as grouping quantitative values into uniform color bins. These distinctions make Opacity the correct setting for modifying visual color intensity.
質問 # 42
Which two elements can have their values changed by using a dashboard action?
正解：C、D
解説：
Tableau dashboard actions can directly change Parameters and Sets, so B and C are correct. A parameter action allows a user to modify a parameter value by interacting directly with marks in a visualization. For example, selecting a mark can assign the mark's Sales value to a parameter, which can subsequently drive a calculated field, reference line, filter logic, or another analytical component. Tableau provides the dashboard action type Change Parameter specifically for this purpose. A set action similarly modifies the membership of an existing set based on interaction with marks. The action can assign selected values to the set, add values, or remove values. This enables sophisticated interactive behavior such as proportional brushing, dynamic comparisons, drill-down effects, and conditional calculations. Tableau identifies this action type as Change Set Values. Groups and bins do not have equivalent dashboard action types that dynamically modify their definitions through viewer interaction. They are data organization constructs configured during authoring. The Tableau Actions documentation explicitly lists Change Parameter and Change Set Values among supported action types. Parameter Actions documentation confirms that visualization interaction can update the target parameter, while Set Actions documentation confirms that interactions can modify values contained in a target set.
