NEW QUESTION # 72
The Movies faceted search report is filtered only when the Apply button for a selected facet is clicked. What must be done in the Page Designer so that report filtering is automatically executed when any facet value changes?
- A. Navigate to each facet and then in the Property Editor, turn on client-Side Filtering.
- B. Navigate to the faceted search region Attributes, and turn off the show Facet Name attribute. Then, navigate to each facet and in the Property Editor, turn on client-Side Filtering.
- C. Navigate to the faceted search region Attributes, and turn off the show Facet Name attribute.
- D. Navigate to the faceted search region Attributes, and disable the Batch Facet Changes attribute
Answer: D
Explanation:
Explanation
A faceted search page is a type of page that allows end users to filter data by applying one or more facets. A facet is a set of filters based on a column or expression. By default, when end users select a facet value, they need to click on an Apply button for that facet to apply the filter to the report. To make report filtering automatically executed when any facet value changes, you need to navigate to the faceted search region Attributes, and disable the Batch Facet Changes attribute. The Batch Facet Changes attribute determines whether end users need to click on an Apply button for each facet or not. When this attribute is disabled, the report is automatically refreshed when any facet value changes. The other options are not relevant to the report filtering behavior.

- C. The right side of the page features a Search Results region, which can display as a classic report or a cards report.
- D. After the end user changes a facet, the results, dependent facets, and occurrence counts refresh immediately.
Answer: A,C,D
Explanation:
Explanation
A faceted search is a type of component that enables users to filter information easily and intuitively by selecting the options in each facet. A faceted search consists of a faceted search region and a search results region. The faceted search region displays on the left and upper part of the screen and shows possible values and occurrence counts for each facet. The search results region displays on the right side of the screen and shows the data that matches the selected facet values. The search results region can display as either a classic report or a cards report. Three of the statements that are true about faceted search are:
After the end user changes a facet, the results, dependent facets, and occurrence counts refresh immediately. This feature provides instant feedback to the user and allows them to refine their search criteria without reloading the page.
The right side of the page features a Search Results region, which can display as a classic report or a cards report. A classic report displays data in a tabular format with columns and rows. A cards report displays data in a grid of cards with images and text.
The facets are displayed on the left and upper part of the screen. This layout provides a clear separation between the facets and the results and allows users to see and access all the facets without scrolling.

A select list can have either static values or dynamic values based on a list of values (LOV). A select list can also have different attributes, such as multiple selection, null value display text, or cascading LOV.
NEW QUESTION # 81
An application includes a report and form on the PRODUCTS table.
The form page includes page items P21 PRODUCT NAME and P21_UNIT_PRICE.
P21_UNIT_PRICE is currently displayed below P21_PRODUCT_NAME.
Now, you need to reposition the items and display P21 UNIT_PRICE next to P21_PRODUCT_NAME.
Which two statements are true?
- A. In Page Designer, select P21_PRODUCT_NAME and then in the Property Editor, under Layout set Start New Row to Yes.
- B. In Page Designer, select P21_UNIT_PRICE and then in the Property Editor, under Layout set Start New Row to Yes.
- C. In Page Designer, use the Middle Pane, click P21 UNIT PRICE and drag the item until it is directly next to P21 PRODUCT_NAME.
- D. In Page Designer, right-click P21_UNIT_PRICE and select Start New Row.
Answer: B,C
Explanation:
Explanation
To reposition the page items and display P21_UNIT_PRICE next to P21_PRODUCT_NAME, you can use either of these methods:
In Page Designer, use the Middle Pane, click P21_UNIT_PRICE and drag the item until it is directly next to P21_PRODUCT_NAME. This method allows you to visually arrange the items on the page layout.
In Page Designer, select P21_UNIT_PRICE and then in the Property Editor, under Layout set Start New Row to Yes. This method changes the attribute of the item to start a new row in the grid layout. The other options, A and D, are incorrect because they would not achieve the desired result. Setting Start New Row to Yes for P21_PRODUCT_NAME would move it to a new row, not next to P21_UNIT_PRICE. Right-clicking P21_UNIT_PRICE and selecting Start New Row would not change the attribute of the item, but only move it to a new position in the Layout tab.
