Explanation
Dynamic actions are a declarative way to define client-side behavior without writing JavaScript code. You can create dynamic actions on an item, button, or region of a page by specifying the event, condition, affected elements, action, and other properties. Some of the statements that are true about creating and using dynamic actions are:
You can execute JavaScript code by creating a dynamic action. One of the supported action types is Execute JavaScript Code, which allows you to enter custom JavaScript code to run when the dynamic action fires.
If a client-side condition is defined, the true action will fire when the condition is met, and the false action will fire when it is not. You can define a client-side condition for a dynamic action to control when it should fire based on an expression or value. You can also define different actions for the true and false branches of the condition. You can add additional true actions to a dynamic action by clicking the Add True Action button in the Property Editor. If no client-side condition is defined, true actions will fire when the event occurs.

Explanation
In Oracle APEX, you can choose from different authentication methods to establish a user’s identity and control access to your application. Authentication may require a user to provide some type of credentials, such as a user name and password, or could involve the use of digital certificates or a secure key. Three of the authentication methods that you can choose in Oracle APEX are:
Custom Authentication Scheme: This method allows you to create your own authentication logic using PL/SQL code or an external web service. You can also customize the login page and session management for your application.
No Authentication (using DAD): This method adopts the current database user as the authenticated user.
This approach can be used in combination with a mod_plsql Database Access Descriptor (DAD) configuration that uses basic authentication to set the database session user.
Built-in Authentication Scheme: This method allows you to use one of the preconfigured authentication schemes that ship with Oracle APEX, such as Open Door Credentials, LDAP Directory, Social Sign-In, and so on.

Explanation
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.

Explanation
Oracle APEX is a low-code application development platform that enables developers to build scalable, secure, and data-driven web and mobile apps. Some of the statements that are true about Oracle APEX are:
APEX eliminates middle-tier application logic. APEX runs entirely within Oracle Database and does not require any additional middleware or application server to function. This simplifies the architecture and reduces the complexity, cost, and security risks of deploying applications.
You can build interactive reporting apps based on data from disparate systems. APEX supports various data sources, such as local database, REST Enabled SQL Service, REST Data Source, Web Source Module, etc. You can use these data sources to create interactive reports that allow end users to filter, sort, search, aggregate, and visualize data from different sources.
The other statements are false because:
Application definition is stored in the database. APEX stores the metadata of the application components, such as pages, regions, items, buttons, etc., in the database tables.
Processing and data manipulation is executed in the database. APEX leverages the power and performance of Oracle Database to process and manipulate data using SQL and PL/SQL.
Running an APEX app does not need client software. APEX apps are web-based and can be accessed from any browser on any device without installing any client software. Verified References: [Oracle Application Express (APEX) – Oracle Help Center], [Platform – Oracle APEX]

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
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
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.

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
Object Browser is a utility in SQL Workshop that enables developers to browse, create, and edit objects in a database. Some of the actions that you can perform using Object Browser are:
Browse database objects of the current schema. You can view the details of an object by selecting it from the Object Tree and then clicking the different object detail tabs.
Create a lookup table based on a column in the current table. You can use the Create Lookup Table option in the Column Details tab to create a new table that stores the distinct values of the selected column and a foreign key constraint to reference it. You cannot restore dropped database objects, create and run SQL scripts, or export and import SQL scripts using Object Browser. You can use other utilities in SQL Workshop to perform these actions, such as Recycle Bin,SQL Commands, and SQL Scripts.

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.

Explanation
A map is a type of component that enables users to view and manage data based on geographic locations. A map consists of a background map and spatial geometry objects that are sourced from data in a table or from a REST data source. Spatial geometry objects are shapes that represent real-world features on a map, such as points, lines, polygons, or heat maps. Three of the supported spatial geometry objects in Oracle APEX are:
Polygons: A polygon is a closed shape that consists of three or more vertices connected by straight line segments. A polygon can represent an area on a map, such as a country, a state, a city, or a building. A polygon can have different colors, patterns, or borders to indicate different attributes or categories of the data.
Heat map: A heat map is a type of visualization that uses color gradients to show the density or intensity of data values in a geographic area. A heat map can represent the distribution or variation of a numeric variable on a map, such as population, income, crime rate, or temperature.
Points: A point is a zero-dimensional shape that represents a single location on a map. A point can have different symbols, sizes, or colors to indicate different attributes or categories of the data. A point can also have a label or a tooltip to display additional information about the data.

Explanation
The Developer Toolbar is a component that appears at the bottom of every page in an Oracle APEX application when running in development mode. The Developer Toolbar provides quick access to various features and tools for developing and debugging an application. One of the options in the Developer Toolbar that enables developers to customize the look and feel of the application is Customize.
Customize: This option opens the Theme Roller tool that allows developers to modify the theme style of the application by changing colors, fonts, sizes, borders, shadows, and more. Developers can also create new theme styles or switch between existing ones using this option.

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.

Explanation
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.

Explanation
The Page Designer Toolbar allows you to perform various actions related to the development of an APEX page. Two of the actions that you can perform are:
Navigate to Shared Components: This option lets you access the shared components of your application, such as lists, breadcrumbs, navigation menus, and so on. You can edit, create, or delete shared components from this option. To access this option, click the icon that resembles a puzzle piece on the Page Designer Toolbar.
Create a new page: This option lets you create a new page for your application using the Create Page Wizard. You can choose from different page types, such as blank page, form, report, chart, calendar, and so on. To access this option, click the icon that resembles a plus sign (+) on the Page Designer Toolbar.
