Using Data Workshop, you can perform the following tasks:

• Load vast amount of data into the database: You can use the Data Load option to load data from various file formats such as XLSX, CSV, XML, and JSON into a table or a collection in your database. You can also use the Data Load Wizard to guide you through the steps of loading data.
• Export vast amount of data from the database into a file: You can use the Data Unload option to export data from a table or a collection in your database into a file in CSV or JSON format. You can also use the Data Unload Wizard to guide you through the steps of exporting data.
• Load data using various file formats such as XLSX, CSV, XML, and JSON: You can use the Data Load option to load data from different file formats into your database. You can choose the file format from a list of supported formats or let Oracle APEX detect it automatically.

The other option is incorrect because:

• Delete data from the database: You cannot use Data Workshop to delete data from the database. You can use SQL Commands or SQL Scripts in SQL Workshop to run DELETE statements to delete data from the database.

In a faceted search page, facets can be displayed as different UI types depending on the data type and cardinality of the facet column or expression. The facet item types are the UI components that are used to render the facets in the faceted search region. The supported facet item types are Range, Checkbox Group, Radio Group, List, Star Rating, and Switch. Date Picker and Popup LOV are not valid facet item types.

Page Designer is a tool that allows developers to create and edit pages in Oracle APEX using a graphical user interface. Page Designer has three main panes: Rendering, Processing, and Property Editor. You can change the layout of Page Designer under Utilities by selecting one of the following options:

• Single Pane Mode - This option displays only one pane at a time. You can switch between the Rendering, Processing, and Property Editor panes by using the buttons on the toolbar or the keyboard shortcuts.
• Two Pane Mode - This option displays two panes side by side. You can choose which panes to display by using the buttons on the toolbar or the keyboard shortcuts. You can also resize the panes by dragging the splitter bar between them. There is no Three Pane Mode or Four Pane Mode option for Page Designer layout.

The Create Page wizard supports three form types that you can create: Interactive Grid, Form, and Master Detail4. An interactive grid is a report that allows users to view and edit data in a tabular format. A form is a page that enables users to update a single row in a database table or view. A master detail is a page that reflects a one-to-many relationship between two tables or views4. An interactive report is not a form type, but a report type that allows users to customize the report layout and filter data interactively5.

As a general rule, you cannot import an application created in a newer release of APEX into an earlier version. This is because the newer release may have features or attributes that are not supported or recognized by the older version. For example, you cannot import an application created in APEX 21.2 into APEX 19.2. However, you can import an application created in an older release into a newer one, as long as the application is compatible with the newer release. For example, you can import an application created in APEX 18.2 into APEX 21.2, but you may need to upgrade or modify some components to use the latest features.

A workspace is a logical work area that enables multiple users to work within the same Oracle APEX installation while keeping their objects, data, and applications private. Creating and managing an APEX workspace involves the following statements:

• During workspace creation, you can associate the workspace with an existing database schema or create a new schema for the workspace. A schema is a collection of database objects such as tables, views, indexes, etc. that belong to a user.
• A workspace enables multiple users to work within the same Oracle APEX installation. Each user can have a different role and privilege in the workspace, such as workspace administrator, developer, or end user.
• A workspace can be associated with one or more schemas. You can add or remove schemas from a workspace after it is created.
• You can create as many workspaces as you need in an APEX Service (APEX Application Development) instance. There is no limit on the number of workspaces per instance.

When you click a Customer Name in the Customers report, the Customer Details form dialog page is displayed. This involves two events: page rendering and page processing. Page rendering is the event that occurs when APEX generates and sends the page to the browser. Page processing is the event that occurs when APEX receives and processes the page from the browser. In this scenario, both events happen because the Customer Details form dialog page is a modal dialog that uses AJAX to communicate with the server without reloading the entire page. Page compilation is not an event, but an action that occurs when APEX compiles an application or a page before running it. 

Oracle APEX provides several preconfigured authentication schemes that follow a standard behavior for authentication and session management. You can select a preconfigured authentication scheme from the gallery when you create an authentication scheme for your application. The preconfigured authentication schemes are:

• Open Door Credentials: This scheme enables anyone to access your application using a built-in login page that captures a user name.
• LDAP Directory: This scheme authenticates a user and password with an authentication request to a LDAP server.
• HTTP Header Variable: This scheme authenticates users externally by storing the username in a HTTP Header variable set by the web server.
• Social Sign-In: This scheme supports authentication with Google, Facebook, and other social networks that support OpenID Connector OAuth2 standards.
• Oracle APEX Accounts: This scheme authenticates users against Oracle APEX user accounts that are created within and managed in the APEX user repository.
• Custom Authentication: This scheme allows you to create a custom authentication scheme from scratch to have complete control over your authentication interface.
• Database Accounts: This scheme authenticates users using database schema accounts.
• Oracle Application Server Single Sign-On Server: This scheme delegates authentication to the Oracle AS Single Sign-On (SSO) Server.
• SAML Sign-In: This scheme delegates authentication to the Security Assertion Markup Language (SAML) Sign In authentication scheme.

To create a REST Enabled SQL Reference, you need to meet the following requirements:

• Install Oracle REST Data Services (ORDS) 19.x or later. ORDS is a Java application that enables developers to create, publish, and manage RESTful web services for Oracle databases1.
• Activate REST Enabled SQL for the target schema on the remote database. REST Enabled SQL is a feature of ORDS that allows you to execute any SQL or PL/SQL through a REST endpoint. You need to enable this feature for the schema that contains the data you want to access2.
• Configure and enable the REST Enabled SQL service feature. This is a workspace-level setting that allows you to use REST Enabled SQL references in your APEX applications. You need to specify a path prefix and a secret for the REST Enabled SQL service3.

You do not need to set up any remote database, as long as it meets the ORDS and REST Enabled SQL requirements. You can use any Oracle database or MySQL database as a remote data source2.

The Column Heading menu of an Interactive Report provides various options to customize the report based on the selected column. The options include:

• Control Break: This option allows you to create a control break on the column, which groups the rows by the column values and inserts a header and a footer for each group. You can also apply aggregate functions, such as sum, count, or average, to the footer of each group.
• Hide: This option allows you to hide the column from the report, which reduces the clutter and improves the readability of the report. You can also show the hidden columns by using the Columns option in the Actions menu.

The other options are incorrect because:

• Group By: This option is not provided in the Column Heading menu of an Interactive Report. It is provided in the Actions menu of an Interactive Report. It allows you to group the rows by one or more columns and display the result in a chart or a pivot table.
• Delete: This option is not provided in the Column Heading menu of an Interactive Report. It is provided in the Data option in the Actions menu of an Interactive Report. It allows you to delete one or more rows from the report and the underlying table.

You can create a report in any of these three methods:

• Create a report as a new page in an application by using the Create Page Wizard. This wizard guides you through the steps of selecting a page type, defining attributes, selecting a source (such as SQL query or table), and adding items or buttons.
• Create a report when you create a new database application by using the Create Application Wizard. This wizard allows you to generate one or more reports based on existing tables or views in your schema. You can also create a report and form on the same table or view.
• Create a report region on a page in an application by using the Page Designer. This tool allows you to drag and drop a region type (such as Classic Report, Interactive Report, or Interactive Grid) onto the page and define its attributes and source.

The other option is incorrect because:

• You cannot create a report from Object Browser. Object Browser is a tool that allows you to view and manage the database objects in your schema, such as tables, views, indexes, etc. You can only run SQL queries or scripts from this tool, not create reports.

A theme is a collection of templates and stylesheets that define the layout and appearance of an application. You can create a custom theme for an application by using the Create Theme Wizard or by copying an existing theme. If you want to use a custom theme for anotherapplication in the same workspace, you can copy the theme to that application by using the Copy Theme option in Shared Components. However, if the master theme (the original theme) may still require changes, you need to subscribe the copied theme to the master theme and refresh the theme whenever there are changes in the master theme. This solution guarantees that any changes to the master theme are reflected in the copied theme by using a synchronization process that updates templates and stylesheets based on their subscription status. Verified References: [Creating Themes - Oracle Help Center], [Managing Theme Subscriptions - Oracle Help Center]

The Create Application Wizard is a tool that allows developers to create a new application by following a series of steps. Some of the actions that you can perform using the Create Application Wizard are:

• Reorder application pages. You can use the Reorder Pages option in the Pages step to change the order of the pages in your application by dragging and dropping them.
• Add or delete application pages. You can use the Add Page or Delete Page options in the Pages step to add new pages or delete existing pages from your application. You can also use the Create Page Wizard to create additional pages after creating the application. You cannot upload JavaScript or CSS files required for an application or change the application authorization using the Create Application Wizard. You can use other features in App Builder to perform these actions, such as Shared Components > User Interface > Files and Shared Components > Security > Authentication Schemes. Verified References: [Creating an Application Using the Create Application Wizard - Oracle Help Center], [Create Application Wizard - Oracle APEX]

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.

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.

Commands allow you to execute SQL statements or PL/SQL blocks to create, edit, view, run, and delete database objects. One of the features of SQL Commands is the ability to unload data from the database to a CSV file. You can do this by clicking the Download button after running a query that returns data.

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.

Theme Styles in Oracle APEX are CSS style sheets that are added to the base CSS of a theme to alter the look and feel of an application. A theme can have multiple theme styles with one style set as current. When the Is Public attribute is enabled for a theme style, end users can choose the theme style from the runtime environment by using the Theme Style Switcher component. This allows end users to customize the appearance of the application according to their preferences.

APP_USER is a built-in substitution string in Oracle APEX that stores the user name of the current user session. The APEX engine uses APP_USER as one component of a key for tracking each user’s session state. As a user navigates from page to page, the APEX engine sets the value of APP_USER to identify the user. The APEX engine also uses APP_USER to perform security checks and conditional processing. You can reference APP_USER using different syntax depending on the context, such as SQL, PL/SQL, or static text.

A stacked master detail is a form type that displays two editable interactive grids based on two related tables or views on the same page. Users select a row in the master grid to update the detail grid6. In this scenario, the departments names with location on the left is the master grid and the employees details on the right is the detail grid. A cards report is not a form type, but a report type that displays data in cards with an image and text7. A side by side master detail is a form type that displays two editable interactive grids based on two related tables or views side by side on the same page. Users select multiple rows in the master grid to update multiple detail grids6. An interactive report is not a form type, but a report type that allows users to customize the report layout and filter data interactively5.

The Approvals component in Oracle APEX is a feature that allows developers to create approval workflows for business processes that require human intervention or decision making. The Approvals component consists of three main elements: Tasks, Task List Page, and Task Details Page. The Unified Task List is a page type in the Create Page Wizard that is used to create a summary of tasks that functions like an inbox for end users. The Unified Task List displays all tasks assigned to or created by an end user along with their status, priority, due date, etc. End users can filter, sort, search, view details, and perform actions on tasks from this page. Verified References: [Using Approvals - Oracle Help Center], [Creating a Unified Task List Page - Oracle Help Center]

Smart Filters is a component that allows end users to filter data by typing keywords in a single search field. Some of the statements that are true about creating and customizing Smart Filters pages are:

• If you create a Smart Filters page based on a table, the filters are auto discovered using the Data Dictionary Cache. You can also manually add or remove filters as needed.
• The suggestion chip count is only displayed for filters that support counts, such as LOV-based filter types. For other filter types, such as Input or Range, the count is not displayed. The search results report cannot be displayed as an interactive report or an interactive grid. The supported report types are Classic Report, Cards, Map, or Calendar.

Low Code Apps are applications that are developed using a low-code development platform such as Oracle APEX. Low Code Apps have the following characteristics:

• Scalable: Low Code Apps can handle large volumes of data and users without compromising performance or reliability. They can also leverage the scalability features of the underlying database or cloud platform.
• Provide Rich Functionality with Less Code: Low Code Apps can provide complex business logic, user interface, security, and integration features with minimal or no coding. They use declarative tools, visual editors, drag-and-drop components, and pre-built templates to speed up the development process.

The other options are incorrect because:

• Not Mobile Friendly: Low Code Apps are mobile friendly by default. They use responsive design techniques to adapt to different screen sizes and orientations. They also support touch gestures, device features, and offline capabilities.
• Expensive: Low Code Apps are not expensive to develop or maintain. They reduce the cost of development by requiring less time, resources, and skills. They also reduce the cost of maintenance by simplifying the deployment, testing, and debugging processes.

Session state management is a feature that enables developers to store and retrieve values for a user as the user navigates between different application pages. A session is a logical construct that establishes persistence (or stateful behavior) across page views. Each session is assigned a unique identifier (or session ID). The statement that is true about session state management in Oracle APEX is:

• APEX Sessions are logically and physically distinct from Oracle database sessions used to service page requests. APEX Sessions are stored in memory within an Application Express engine process while Oracle database sessions are stored in memory within an Oracle database process. The other statements are false because:
• A user can run multiple instances of an application simultaneously in different browser programs by using different session IDs.
• Multiple number of sessions can exist in the database at the same time for different users or applications. Verified References: [Understanding Session State Management - Oracle Help Center], [What Is a Session? - Oracle Help Center]

 Public reports are available to all users who can access the interactive grid1. However, to enable an end user to save a public interactive grid report, the user must have the required permission. By default, only developers can save public reports1. Any user may save private interactive grid reports, but only the user who creates a private report can view, save, rename, or delete it12.

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.

 A modal dialog is a type of page mode that displays an overlay window within the viewport when a button is pressed. A modal dialog is a stand-alone page that does not interact with the base page where it was launched. A modal dialog blocks access to the base page until it is closed by the user. A modal dialog can be used for various purposes, such as displaying additional information, confirming an action, or collecting user input.

One-click remote application deployment is a feature in Oracle APEX that simplifies the process of deploying an application from one APEX instance to another using REST Enabled SQL references. REST Enabled SQL references are shared components that work with an Oracle REST Data Services (ORDS) REST Enabled SQL Service. One-click remote application deployment can authenticate through first party authentication (Basic Authentication), Schema Authentication (database username and password), or OAuth 2 Client Credentials. Two of the advantages of using one-click remote application deployment are:

• Deploy the app, and explicitly install the supporting objects in one-click. This advantage allows you to package the app definition along with the database objects, images, and seed data necessary for your application to run correctly using the Supporting Objects functionality in APEX. You can then export and deploy this app and install the supporting objects in one-click without having to manually create or copy the database objects in the target system.
• Directly deploy your app definition along with the objects from the source system to the target system. This advantage allows you to avoid the intermediate step of exporting the app and its objects from the source system into files and then importing them into the target system. You can directly deploy your app and its objects from within your development environment to the remote production environment without having to access your production environment.

An Interactive Report and an Interactive Grid are two types of regions that allow end users to customize how and what data is displayed. They have some common capabilities such as:

• End users can add, modify, and refresh data directly on the report by using the Edit option. This option enables inline editing or modal dialog editing depending on the region settings.
• End users can customize how and what data is displayed by using the Actions menu. This menu provides various options such as Filter, Highlight, Aggregate, Chart, Group By, Pivot, etc.

The other options are incorrect because:

• End users cannot rearrange the report interactively using the mouse in an Interactive Report. This capability is only available in an Interactive Grid by using the Reorder option in the Actions menu.
• End users cannot save the report in an Interactive Grid. This capability is only available in an Interactive Report by using the Save Report option in the Actions menu.
