An interactive grid is a customizable report that allows end users to modify the data and layout of the report. End users can change the report layout by using the Actions menu or by dragging and dropping columns. They can also create private reports that save their personal preferences for the report. These features are available for both editable and noneditable interactive grids. Verified References: Using an Interactive Grid - Oracle Help Center, Example Interactive Grid - Oracle Help Center

To migrate an APEX app between environments, such as from development to production, you need to consider three components that make up an APEX app:

• Database objects: These are the tables, views, procedures, functions, packages, triggers, sequences, synonyms, and other schema objects that store or manipulate the data used by the app. You need to move these objects from the source schema to the target schema using tools such as SQL Developer, Data Pump Export/Import, or Data Workshop.
• Images: These are the static files, such as images, CSS files, JavaScript files, or PDF files, that are used by the app for display or download purposes. You need to move these files from the source web server to the target web server using tools such as FTP, SCP, or File Explorer.
• Application definition and all associated files: These are the metadata files that define the app components, such as pages, regions, items, buttons, processes, validations, computations, dynamic actions, shared components, and so on. You also need to include any supporting object definitions or data scripts that are used to create or populate database objects for the app. You need to move these files from the source APEX instance to the target APEX instance using tools such as App Builder Export/Import or One-click Remote Application Deployment.

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.

In a Classic Report, an end user can perform the following actions:

• Filter values of a column in the report by using the Search Bar. This bar allows the user to enter a search string and apply it to one or more columns in the report.
• Sort the columns of the report by clicking on the column headers. This action toggles the sort order between ascending and descending for the selected column.

The other options are incorrect because:

• Create Control Breaks in the report is not an action that an end user can perform in a Classic Report. This action is only available in an Interactive Report by using the Control Break option in the Actions menu.
• Rearrange the columns in the report is not an action that an end user can perform in a Classic Report. This action is only available in an Interactive Grid by using the Reorder option in the Actions menu.

In an Employee form, the ‘Commission’ and ‘Hire Date’ fields are enabled only if the Job is ‘Salesman’. This can be achieved by using Dynamic Actions in APEX. Dynamic Actions are declarative components that define client-side behavior without writing JavaScript code. You can create Dynamic Actions on items, buttons, or regions of a page by specifying an event, a condition, an action, and other properties. In this scenario, you can create a Dynamic Action on Job item with Change as event, Execute JavaScript Code as action, and use jQuery to enable or disable Commission and Hire Date fields based on Job value. Processing, Conditional SQL, and PL/SQL procedure are not features of APEX that can achieve this requirement without writing JavaScript code.

A map is a type of component that enables you 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. Two of the statements that are true about maps in Oracle APEX are:

• Background maps do not require any API keys. This statement is true because Oracle APEX provides several background map options that do not require any API keys or registration to use. These options include OpenStreetMap, Stamen Maps, CartoDB Maps, and Esri Maps.
• Maps support REST Enabled SQL. This statement is true because Oracle APEX allows you to use REST Enabled SQL as a data source for your map regions. REST Enabled SQL is a feature of Oracle REST Data Services (ORDS) that enables you to execute SQL statements and PL/SQL blocks over HTTPS using REST endpoints.

Custom Apps are specific to your workspace and are only available if your instance administrator has enabled them. You can install Sample Apps and Starter Apps directly from the Gallery or download them from GitHub. Sample Apps and Starter Apps are available with every Oracle APEX workspace.

Universal Theme is a responsive, versatile, and customizable user interface for your APEX apps. It is designed uniquely for Oracle APEX to make it easy for developers to build beautiful, modern applications, at any scale, for any purpose, that work on any device. All of the statements given are true about Universal Theme:

• Features a responsive design and enables developers to create web applications without extensive knowledge of HTML, CSS, or JavaScript. Universal Theme adapts to different screen sizes and devices using CSS media queries and grid layout. It also provides a rich set of UI components, template options, and theme styles that can be used declaratively without writing custom code.
• Universal theme is the default theme that is shipped with Oracle APEX. Universal Theme is the default theme for new applications created in APEX 5.0 or later. It is also the recommended theme for upgrading existing applications to the latest version of APEX.
• Uses a 12-column grid layout system for arranging components on a page. Ships with a variety of pre-built theme styles. Universal Theme uses a 12-column grid layout system based on Flexbox to arrange components on a page. It also ships with a variety of pre-built theme styles that can be applied to change the look and feel of the application.
