質問 # 80
Which two are true when the Edit option is NOT enabled for an Interactive Grid?
- A. The end user cannot edit the underlying data in the database
- B. The end user cannot create charts
- C. The end user can edit the underlying data in the database
- D. The end user can customize the report
正解：A、D
解説：
Explanation
An interactive grid is a component that displays data in a tabular format and allows users to perform various actions on the data, such as sorting, filtering, grouping, highlighting, and editing. However, the editing feature is optional and can be enabled or disabled by the developer. When the Edit option is not enabled for an interactive grid, the following statements are true:
The end user cannot edit the underlying data in the database. The interactive grid becomes read-only and does not allow users to add, modify, or delete rows. The Add Row and Save buttons are hidden from the toolbar and the cells are not editable.
The end user can customize the report. The interactive grid still allows users to change the appearance and behavior of the report using the Actions menu. Users can perform actions such as changing column order, resizing column width, hiding or showing columns, applying filters or highlights, creating control breaks or charts, and saving reports.
質問 # 81
Consider a customers report. A customer name is clicked in the report to display the Customer Details form. When the items in the form dialog are updated and the user clicks Apply Changes, the page process is executed and the items from the page are used to update and commit the underlying table in the Oracle Database. What are the two types of events that occurred in this scenario?
- A. Page Refresh
- B. Page Processing
- C. Page Validation
- D. Page Rendering
正解：B、C
解説：
Explanation
When the customer name is clicked in the report, the Customer Details form dialog page is displayed. This is a page rendering event, which means the page is generated and sent to the browser. When the items in the form dialog are updated and the user clicks Apply Changes, the page process is executed and the items from the page are used to update and commit the underlying table in the Oracle Database. This is a page processing event, which means the page is submitted to the server and processed by APEX. Page validation is also a part of page processing, but it is not a separate event. Page refresh is not an event, but an action that can be triggered by a dynamic action or a process
質問 # 82
Which two statements are true about Faceted Search pages?
- A. Multiple charts are not visible in the same region.
- B. Facets map to specific database columns.
- C. A facet's chart can be seen only in a nonmodal dialog.
- D. Faceted Search supports the ability to filter columns storing multiple values as one string.
正解：B、D
解説：
Explanation
Faceted Search is a feature 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. Faceted Search supports the ability to filter columns storing multiple values as one string, such as comma-separated values or JSON arrays, by using the Split Values attribute. Facets map to specific database columns or expressions that are defined in the Data Source attribute of the faceted search region. The other statements are false because Faceted Search supports displaying multiple charts in the same region by using the Chart View attribute, and a facet's chart can be seen either in a nonmodal dialog or inline by using the Chart Display Mode attribute. Verified References: [Creating Faceted Search Pages - Oracle Help Center], [Facet Attributes - Oracle APEX]
質問 # 83
What are the three types of Master Detail Form you can create in APEX?
- A. One Below the other
- B. Side by Side
- C. Stacked
- D. Two Page Drill Down
正解：B、C、D
解説：
Explanation
A master detail form is a type of form that enables users to query, insert, update, and delete values from two related tables or views. A master detail form reflects a one-to-many relationship between tables in a database.
Typically, a master detail form displays a master row and multiple detail rows. In APEX, you can create three types of master detail forms using the Create Page Wizard or the Create Application Wizard:
Stacked: A stacked master detail form contains a single page with editable interactive grids based on two related tables or views. Users select a row in the master grid to update the detail grid. Developers can create a stacked master detail with either the Create Application Wizard or the Create Page Wizard.
Side by Side: A side by side master detail form contains a single page with two editable interactive grids based on two related tables or views. Users can see and edit both the master and detail grids at the same time. Developers can create a side by side master detail with either the Create Application Wizard or the Create Page Wizard.
Two Page Drill Down: A two page drill down master detail form contains two pages based on two related tables or views. The first page is a non-editable interactive grid for the master table. Users click the Edit icon on the first page to edit details on the second page. The second page includes both a standard form for the master and an editable interactive grid for the detail. Developers can create a two page drill down master detail with only the Create Page Wizard.

質問 # 85
Which two statements are TRUE about Dynamic Actions?
- A. Dynamic actions provide a way to define complex client-sidebehaviordeclaratively without the need for JavaScript.
- B. Dynamic Actions require complex client side Javascript code
- C. More dynamic actions you add to a page, the greater your overall page size.
- D. It is not possible to debug Dynamic Actions from the Developer Toolbar
正解：A、C
解説：
Explanation
Dynamic actions provide a way to define complex client-side behavior declaratively without the need for JavaScript. You can create dynamic actions on items, buttons, or regions of a page by specifying an event, a condition, an action, and other properties1. However, more dynamic actions you add to a page, the greater your overall page size. This can affect the performance and user experience of your application2. It is possible to debug dynamic actions from the Developer Toolbar by using the Debug option3. Dynamic actions do not require complex client-side JavaScript code, but they can optionally include custom JavaScript code as an action or a condition1.
質問 # 86
Select two features of a Smart Filters Page.
- A. Each filter represents the text entered by the end user in the search field
- B. Consists of a single search field with filters at the top of the page and a report at the bottom
- C. Each filter displays as a suggestion chip with a single count of how often the specific suggestion value occurs.
- D. Consists of filters at the left side and report on the right side of the page
正解：B、C
解説：
Explanation
A smart filters page is a type of component that features a single search field at the top of the page and a search results report (classic report, cards, map, or calendar) at the bottom. A smart filters page behaves similarly to faceted search, but it features a more space efficient layout. Two of the features of a smart filters page are:
Consists of a single search field with filters at the top of the page and a report at the bottom. This feature provides a simple and compact user interface that allows users to enter text in the search field and see suggested filters based on their input. Users can also see and modify applied filters at any time.
Each filter displays as a suggestion chip with a single count of how often the specific suggestion value occurs. This feature provides useful information to users about how many records match each filter value. Users can also choose between different types of suggestions, such as dynamic, static, or SQL query.

To create a Dynamic Action, you need to specify which three of the following options?
- A. When the action occurs
- B. Why the action is performed
- C. What elements are affected by the action
- D. What action or actions are performed
正解：A、C、D
解説：
Explanation
To create a dynamic action, you need to specify at least three options: what action or actions are performed, when the action occurs, and what elements are affected by the action1. The action is the behavior that you want to happen when the event is triggered. You can choose from a list of predefined actions or create your own custom action using JavaScript code1. The event is the user interaction or condition that causes the dynamic action to fire. You can select an event from a list of available events based on the type of element you select1. The affected elements are the items, buttons, or regions that are affected by the action. You can select one or more elements by using jQuery selectors1. You do not need to specify why the action is performed, as this is not a required option for creating a dynamic action.
