Explanation
REST Data Source Synchronization is a feature that enables developers to automatically sync the contents of a local table with the data from an external REST service. To execute REST source synchronizations on schedule, the CREATE JOB privilege must be granted to the application’s parsing schema, which allows APEX to create a DBMS_SCHEDULER job for each scheduled synchronization task. If the local table is not in sync with the Data Profile, which defines the columns and data types of the REST service response, Data Synchronization continues to work for columns present in both the table and the Data Profile (other columns are ignored). However, APEX generates SQL DDL statements to sync table columns back to the Data Profile, which can be added to the application as supporting objects.

Explanation
You can access the Shared Components page from two places in App Builder: the Page Designer and the Application home page. In Page Designer, you can click on the Shared Components icon at the top of the page to open the Shared Components page in a new tab5. In the Application home page, you can click on the Shared Components link in the center of the page to navigate to the Shared Components page6. Gallery, SQL Workshop, and other pages do not have direct links to the Shared Components page.

Explanation
A plugin is a component that extends the native functionality of Oracle APEX by allowing developers to create custom components using SQL, PL/SQL, HTML, CSS, and JavaScript. A plugin can be created for any of the following component types: Dynamic Action, Item, Process, Region, Report Layout, Authentication Scheme, Authorization Scheme, or Data Load Method. A process plugin is a custom process type that can be executed when a page is submitted or loaded. A region plugin is a custom region type that can display data or content on a page.

Explanation
Search configuration is a shared component that defines the data source to be searched and the way results should be displayed. You can create a search configuration based on a local data source (table or SQL query), an APEX list, a REST enabled SQL service, or a REST data source2. You can use one or more search configurations in a search page, depending on the search type you select. For example, you can use multiple search configurations for a standard search, but only one search configuration for an Oracle TEXT or a list search2.

Explanation
You can create a report with form in Oracle APEX by using either the Create Application Wizard or the Create Page Wizard. The report can be either an interactive report or a classic report, and the form can be either a single row form or a multi row form. The report with form combination enables you to view and edit data from a table or a query in a single page. You can also customize the report and form attributes, such as the columns, regions, buttons, validations, processes, and so on.

Explanation
The friendly URL syntax
https://example.com:5500/ords/r/mycompany/hr-app/updateemployees?session=13766599855150 has the following components:
session=13766599855150 is the session ID. A new ID is generated for each session. This parameter identifies which session is associated with the request.
hr-app is the application alias. This parameter identifies which application is being requested. An application alias is a user-friendly name that can be used instead of an application ID.
mycompany is the path-prefix which is by default the workspace name. This parameter identifies which workspace is being requested. A path-prefix is a URL segment that can be used instead of a workspace ID.
updateemployees is the page alias. This parameter identifies which page is being requested. A page alias is a user-friendly name that can be used instead of a page number.
The other option is incorrect because:
update-employees is not the PL/SQL procedure to update the employee details. It is the page alias that identifies which page is being requested.

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.

Explanation
The “Create an Application From a File” wizard is a tool that allows developers to create an application based on an existing spreadsheet file or sample data set. Some of the statements that are true about loading data from this wizard are:
A sample data set from the sample list can be uploaded. You can use the Sample Data Sets option to select a predefined data set from a list of available samples, such as Employees, Products, Projects, etc.
CSV, XLSX, XML, TXT, or JSON files can be uploaded. You can use the Upload a File option to upload a spreadsheet file in one of these formats and create an application based on its data. You cannot upload seed data from a SQL script, paste and load XML and JSON data, or upload data from remote web services using this wizard. You can use other features in App Builder or SQL Workshop to perform these actions, such as SQL Scripts, RESTful Services, etc. VerifiedReferences: [Creating an Application From a File – Oracle Help Center], [Creating an Application Based on Sample Data Sets – Oracle Help Center]

Explanation
A Faceted Search and a Smart Filter are two types of pages that behave similarly in functionality. They both allow users to filter data based on multiple criteria and see the results in real time. They differ in the following aspects:
A Faceted Search uses facets to filter data. A facet is a set of filters based on a column or expression. A facet can be displayed as a list, a range slider, a star rating, or a chart.
A Smart Filter uses conditions to filter data. A condition is a logical expression that evaluates to true or false. A condition can be based on a column, an item, or a function.
The other options are incorrect because:
A Map is a type of region that displays spatial data on an interactive map. It allows users to zoom, pan, and select features on the map.
A Cards is a type of region that displays data in a grid of cards. Each card represents one row of data and can contain text, images, icons, or buttons.

Explanation
An interactive grid is a customizable report that allows end users to modify the data and layout of the report.
To make an employee’s commission editable in the grid, you need to perform two actions:
In the Interactive Grid attributes, turn “On” the Enabled switch, under the Edit group. This enables editing for the entire interactive grid region and allows you to specify which columns are editable and which are not.
Ensure that the “Primary Key” switch is turned “On” for the EMPNO column. This identifies the EMPNO column as the primary key for the EMP table and allows APEX to perform DML operations on the table when end users edit the data in the grid. You do not need to set EMPNO or ENAME to
“Display Only” or select COMM for “Allowed Row Operations Column” to make an employee’s commission editable in the grid. Verified References: [Managing Interactive Grids – Oracle Help Center], [Interactive Grid Attributes – Oracle Help Center]

Explanation
Data Load Definition is a feature that enables developers to create pages with data loading capability. Users can upload files and load data into tables or collections. Some key features of Data Load Definition are:
The APEX_DATA_LOADING PL/SQL API is available for custom processing. Developers can use this API to programmatically load data by calling an application data loading definition .
Column mapping occurs at design time, removing the burden on end users. Developers can define SQL expressions, SQL queries, lookups, or transformation rules for each data profile column.
Easy workflow for end users: upload the file, verify the preview, and load data. Users can follow a simple three-step process to load data from a file into a table or a collection.
Data Load Definition does not support only XML data format. It also supports CSV, JSON, XLSX, and XML formats.

Explanation
You can create a chart in an interactive grid by selecting Chart in the Actions menu. You can only create one chart at a time in an interactive grid. To create a second chart, you have to reconfigure or delete the existing chart1. To remove a chart, you can click the Remove Chart icon (X) adjacent to the chart filter12. Once a chart is created, you can switch the view between Grid and Chart by clicking the toggle that appears at the top of the interactive grid

Explanation
A chart is a type of component that enables users to visualize data in different ways and perform data analysis.
A chart can display data in various formats, such as bars, lines, areas, ranges, combinations, scatters, bubbles, polars, radars, pies, donuts, funnels, and more. Oracle APEX supports charts based on the Oracle JavaScript Extension Toolkit (Oracle JET) Data Visualizations. Oracle JET is a modular open source toolkit based on modern JavaScript, CSS3, and HTML5 design and development principles. Three of the correct statements about charts in Oracle APEX are:
You can visualize data as bar, line, area, range, combination, scatter, bubble, polar, radar, pie, donut, funnel and more. This statement is true because Oracle APEX provides a rich set of chart types that can be used to display data in different ways and support different analysis scenarios. You can choose from over 20 chart types when creating a chart in Oracle APEX.
Oracle APEX supports charts based on the Oracle JavaScript Extension Toolkit (Oracle JET) Data Visualizations. This statement is true because Oracle APEX uses Oracle JET as the underlying technology for rendering charts in the browser. Oracle JET provides high-performance and interactive data visualizations that are compatible with various devices and browsers.
Each Oracle JET visualization supports animation, accessibility, responsive layout, internationalization, test automation, and a range of inter activity features. This statement is true because Oracle JET offers many features and capabilities that enhance the user experience and functionality of the charts. For example:
Animation: Charts can have smooth transitions and effects when loading or updating data.
Accessibility: Charts can support keyboard navigation, screen reader compatibility, and high contrast mode for users with disabilities.
Responsive layout: Charts can adapt to different screen sizes and orientations by resizing or repositioning elements.
Internationalization: Charts can support different languages, date formats, number formats, and text directions for users from different regions.
Test automation: Charts can support automated testing tools and frameworks by providing unique identifiers for elements.
Interactivity: Charts can support user actions such as zooming, panning, filtering, selecting, drilling down, or popping up tooltips.

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. Verified References: [Faceted Search Attributes – Oracle Help Center], [Batch Facet Changes – Oracle APEX]

Explanation
Data Synchronization enables developers to automatically sync the contents of a local table with the data from a REST service. APEX invokes the REST service defined in the REST Data Source, downloads all data and synchronizes it to a local table6. Data Synchronization has several benefits, such as:
APEX can create the local table based on the visible columns in the REST Data Source Data Profile. Since the table is physically available in the database schema, developers can add indexes, change physical properties, or even add more columns6.
Data Synchronization helps in providing efficient reporting on large data sets coming from a REST service. Some REST services can return large amounts of result data that include pagination. If a reporting requirement needs larger data sets, this would lead to multiple HTTP requests and poorer response times. Also, no indexes or other database features can be used to speed up reporting queries. In this case, synchronizing the remote data to a local table and having the reports working on local tables can improve performance and user experience6.
Data Synchronization can also collect data from REST services for consumption by PL/SQL packages or other logic. If data from the REST service is replicated to local tables, developers will be able to perform all sorts of processing and also generate different types of reports6.
You do not have to trigger Data Synchronization manually, as you can also schedule it to run periodically using a DBMS_SCHEDULER expression6.

Explanation
When you run an application, the APEX engine relies on two processes: Show Page and Accept Page. Show Page is responsible for rendering the page and sending it to the browser. Accept Page is responsible for processing the page when it is submitted by the browser. Run Page is not a process, but a command that can be used to run an application or a page from SQLWorkshop or Application Builder. Validate Page is not a process, but a step that occurs during page processing to check for any validations defined on the page

Explanation
There are three different ways in which you can add a checkbox to a page in APEX:
Drag and drop the checkbox item into the Layout pane: In Page Designer, you can drag and drop items from the Gallery pane into the Layout pane to create them on your page. To create a checkbox item, expand the Items node in the Gallery pane and drag and drop Checkbox into the Layout pane.
Right click Body in the Rendering Tree and add a New Page Item as Checkbox Type: In Page Designer, you can right click any node in the Rendering tree andselect Create to create a new component under that node. To create a checkbox item under the Body node, right click Body and select Create > New Page Item > Checkbox.
Use the context sensitive menu in the Gallery pane: In Page Designer, you can use the context sensitive menu in the Gallery pane to create items on your page. To create a checkbox item using this method, expand the Items node in the Gallery pane and right click Checkbox. Then select Create Checkbox.
