Importing an APEX application involves transferring its definition (exported as a .sql file):

C. You cannot import an APEX application exported from the latest APEX version to an old APEX version: APEX enforces backward compatibility limits. An app exported from 23.2 (latest features like AI Assistants) can’t import into 19.2, as older versions lack support for newer metadata (e.g., APEX_AI tables). The import wizard checks the version and rejects incompatible files.

A. You cannot change the application ID: False; the import wizard prompts for a new ID if there’s a conflict or if you choose to override.

Object Browser in SQL Workshop is a GUI for managing schema objects:

B. Browse database objects of the current schema: Displays tables, views, procedures, etc., in a tree view, allowing inspection of definitions (e.g., columns, constraints) and data previews.

D. Create a lookup table based on a column in the current table: From a table’s column (e.g., DEPTNO), you can generate a lookup table (e.g., DEPT_LOOKUP) with unique values, automating reference table creation.

A. Restore dropped objects: Not supported; this requires DBA tools (e.g., FLASHBACK TABLE).

The Universal Theme (Theme 42) provides pre-built components:

A. Calendar: A region type for date-based displays (e.g., events), styled with Universal Theme templates (e.g., FullCalendar integration).

B. Comments: A region type for user feedback or notes, with built-in styling and moderation options.

C. Badge: A UI component for displaying counts or statuses (e.g., "5 New"), often in navigation or lists, styled via CSS classes.

The Create Application Wizard streamlines app creation with:

Adding or deleting application pages: Allows users to define initial pages (e.g., Home, Reports) and remove unwanted ones during the wizard process.

Reordering application pages: Provides drag-and-drop or list-based reordering of pages to set the navigation sequence.

Uploading JavaScript or CSS: This occurs post-creation in Shared Components, not within the wizard.

A dynamic List of Values (LOV) in APEX populates options based on a query source. The supported types include:

Function Returning SQL Query: A PL/SQL function that returns a SQL query string (e.g., RETURN 'SELECT ename, empno FROM emp';). This offers flexibility for dynamic conditions or complex logic.

SQL Query: A direct SQL statement (e.g., SELECT ename, empno FROM emp) executedat runtime to fetch LOV values. It’s the simplest and most common approach.

Procedure: Procedures execute logic but don’t return query results in the format required for an LOV (they don’t produce a result set directly).

Logging in APEX tracks runtime activity:

A. apex_automation.log_info: Correctly logs an informational message to the execution log for automation tasks (e.g., workflows). The syntax || :ENAME || concatenates the item value (e.g., "JOHN") into "SAL for JOHN increased by 19." It’s stored in APEX_AUTOMATION_LOG, viewable in Monitoring.

B. apex_debug.info: Logs to debug output, but the syntax is flawed (:ENAME || isn’t concatenated properly; should be 'SAL for ' || :ENAME || ...). It’s valid only when debugging is enabled (e.g., APEX_DEBUG.ENABLE).

Regenerating Push Notification credentials updates the VAPID keys (public/private pair) in the PWA settings:

A. Existing Push Subscriptions invalidated: Subscriptions (in APEX_APPL_PUSH_SUBSCRIPTIONS) are tied to the old keys. New keys break this link, requiring users to re-subscribe (e.g., via browser prompts), as the push service (e.g., Firebase) can’t authenticate old subscriptions.

B. New notification server: False; the server configuration remains; only credentials change.

Declarative options for downloading BLOB/CLOB content include:

Download Dynamic Action: A built-in action type to trigger downloads of BLOB/CLOB data.

Static Content regions display fixed text with substitution:

B. &P1_ENAME.: The &ITEM_NAME. syntax substitutes the value of P1_ENAME at runtime (e.g., "Join me in congratulating: John as..."), correctly rendering the item’s value. The dot ensures proper parsing.

A. P1_ENAME: Treated as literal text, not substituted.

C. V('P1_ENAME'): A PL/SQL function, invalid in static content; it’s for server-side code.

APEX Workspaces define development environments tied to database schemas:

A. During workspace creation, you can associate the workspace with an existing database schema: In the Workspace creation wizard (via Instance Administration), you select an existing schema (e.g., "HR") to link, enabling access to its objects. This is a standard step, ensuring immediate usability.

B. New schemas cannot be created during workspace creation: APEX doesn’t provide a UI to create schemas here; schemas must pre-exist in the database, created via SQL (e.g., CREATE USER).

C. A workspace can be associated with only one schema: False; a workspace can associate with multiple schemas post-creation via "Manage Workspace to Schema Assignments."

Enabling "Used by App Builder" for a Generative AI Server allows:

Author SQL powered by Generative AI: Integrates AI-driven SQL generation in App Builder.

In SQL Workshop, custom stored procedures can be created using:

SQL Scripts: Allows developers to write and execute PL/SQL code directly to define stored procedures.

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 APEX_PWA package manages Push Notifications:

B. APEX_PWA.PUSH_QUEUE: This procedure forces immediate processing of the Push Notification queue, sending queued messages (added via APEX_PWA.SEND) to subscribed devices without waiting for the default scheduler (e.g., every 5 minutes). Example: APEX_PWA.PUSH_QUEUE; ensures a "Meeting now!" alert goes out instantly.

A. APEX_PWA.HAS_PUSH_SUBSCRIPTION: Checks if a user has an active subscription (returns BOOLEAN), not for sending.

Dynamic Actions in APEX enable responsive behavior:

If a client-side condition is defined, the true action will fire when the condition is met: A condition (e.g., this.browserEvent === 'click') ensures the true action (e.g., Show, Hide) executes only when true, enhancing precision in event handling.

You can execute JavaScript code by creating a dynamic action: The "Execute JavaScript Code" action type allows custom scripts (e.g., alert('Clicked!');), extending functionality beyond declarative options.

Cannot add more true actions: False; multiple true actions can be added post-creation.
