Which action describes the process for changing a measure so that it automatically aggregates an average instead of a sum?
Answer : A
To change a measure so that it automatically aggregates as an average instead of a sum, you should right-click the field in the Data pane and select Default Properties. In the Default Properties menu, you can set the default aggregation for the measure, such as setting it to calculate an average by default when added to a view.
You have a continuous numeric measure named Sales.
Which chart type is created when you double-click the Sales measure?
Answer : D
When you double-click a continuous numeric measure named Sales in Tableau, it automatically creates a bar chart. Tableau's default behavior for a single measure is to display it as a bar chart, with the measure values represented on the Y-axis and an automatic range on the X-axis.
You need to display the complete list of potential data connections when you connect to a server. What action should you perform?
Answer : C
To display the complete list of potential data connections when connecting to a server in Tableau, you should select 'More' under the 'To a Server' option. This action will provide a comprehensive list of server types and data sources that Tableau can connect to.
You have the following string value: Sales Data.
Which calculated field produces an output of Sales?
Answer : B
The calculated field formula LEFT('Sales Data', 5) will correctly produce the output 'Sales' from the string value 'Sales Data'. The LEFT function in Tableau returns the specified number of characters from the start of the string. Here, the first 5 characters of 'Sales Data' are 'Sales'.
Which type of filter affects a fixed Level of Detail (LOD) expression?
Answer : D
In Tableau, a Fixed Level of Detail (LOD) expression calculates values at a specific level of granularity, regardless of the dimensions in the view. The computation of a fixed LOD expression can be influenced by a context filter. A context filter serves as a primary filter, setting the context for the rest of the filters in the view. When a context filter is applied, it effectively changes the level at which the fixed LOD expression is computed, thereby affecting its outcome. Other types of filters, such as table calculation, measure, and dimension filters, do not have this influence on fixed LOD expressions.
