An editable Interactive Grid synced with a REST Data Source (ORDS) maps CRUD operations to HTTP methods:

C. PUT: Updates an existing resource. When a user edits a row (e.g., changes SALARY), the grid sends a PUT request to the ORDS endpoint (e.g., /employees/101), updating the corresponding record.

A. POST: Creates new records, used for inserts, not updates.

Oracle APEX integrates with external AI service providers to power features like Generative AI and text generation. The supported providers are:

OpenAI: A widely recognized AI provider offering models like GPT, integrated via API keys for tasks such as text generation, summarization, or SQL authoring in APEX.

OCI Generative AI: Oracle Cloud Infrastructure’s native AI service, optimized for Oracle ecosystems, providing secure, scalable AI capabilities directly within the OCI environment.

DOC Document Generator: This is not an AI service provider; it’s a hypothetical or misnamed option unrelated to APEX’s AI integration.

The "Create App using Generative AI" feature in APEX Assistant leverages natural language processing to automate application creation. When invoked:

Create the application blueprint: APEX Assistant generates a foundational structure (blueprint) for the application, including pages, regions, and navigation, based on the user's natural language input (e.g., "Create an app to manage employees"). This blueprint serves as the starting point, which developers can refine.

Add a Dashboard page: The Assistant can interpret requests for specific page types, such as dashboards, and include them in the generated app. Dashboards typically feature charts, summaries, or key metrics, and this is a common task supported by the AI-driven creation process.

Create a Generative AI service: This is not a task performed during app creation; instead, it’s a prerequisite configuration step done separately in the Instance Administration settings.

To use REST-enabled SQL in APEX:

Install ORDS 19.x or later: Oracle REST Data Services (ORDS) must be installed and configured on the remote database.

Master-detail pages in APEX link a master dataset (e.g., list of orders) to its details (e.g., order items). The requirements demand:

C. Side by Side: This layout places the master region (e.g., an Interactive Report) and detail region (e.g., a Form or Grid) horizontally on the same page. Selecting a master row updates the detail region via AJAX, allowing interaction with both regions without navigation. It’s ideal for workflows needing simultaneous visibility (e.g., editing details while browsing masters).

A. Drill Down: Master links to a separate detail page, requiring navigation, which violates the "without leaving the page" condition.

To enable an existing APEX application as a Progressive Web App (PWA), the mandatory step is:

Enable the PWA flag in the Application Definition: In the Application Definition attributes under "Progressive Web App," setting "Enable PWA" to "Yes" activates PWA features like installability, push notifications, and service worker generation. This is the foundational step, after which optional customizations (e.g., icons, manifest) can be added.

Friendly URLs: While recommended for modern apps, they’re not required for PWA functionality.

Custom JavaScript: Optional for offline capabilities, but not mandatory for basic PWA enablement.

Plugins extend APEX’s functionality beyond built-in components:

C. Process: A Process plugin executes custom server-side logic (e.g., PL/SQL) during page processing or AJAX calls. Example: A plugin to sync data with an external API after form submission. It’s defined with execution points and parameters.

D. Region: A Region plugin creates custom UI areas (e.g., a dynamic chart or carousel). Example: A plugin rendering a custom dashboard. It supports attributes, templates, and refresh events.

A. Validation: While validations are customizable, they’re not a plugin type; they’re declarative or PL/SQL-based within APEX.

The Link Column in an Interactive Report adds a clickable link to each row. The true statement is:

It is not possible to exclude Link Column: Once defined in the report attributes, the Link Column is mandatory and cannot be hidden or excluded via end-user controls (e.g., Column Management). It’s always rendered unless removed by the developer.

Custom target: False; custom targets (e.g., URLs, pages) can be defined.

Always last column: False; its position is configurable.

In Oracle APEX, a faceted search page allows users to filter data using facets, which are displayed as UI components in the Faceted Search region. According to the Oracle APEX documentation, the supported facet item types include:

Range: Used for numeric or date ranges, allowing users to filter data within a specified range (e.g., salary or hire date).

Data Workshop in SQL Workshop is a powerful tool for importing/exporting table data:

B. You can load or unload a single table at a time: The wizard focuses on one table per operation. For loading, you upload a file (e.g., CSV) and map it to a single table; for unloading, you select one table to export (e.g., EMP to CSV). This granularity ensures precision and simplicity.

C. You can unload data from a new or existing table: Unloading (exporting) works on any table in the schema, whether newly created (e.g., via Quick SQL) or pre-existing (e.g., DEPT). The "Unload" option generates a file (e.g., CSV, JSON) from the table’s data.

D. You can load data into a new or existing table: Loading supports creating a new table from the uploaded file (e.g., CSV defines NEW_EMP) or appending/overwriting an existing one (e.g., EMP). The wizard prompts for table creation or selection.
