1z0-771 Oracle APEX Cloud Developer Professional Questions and Answers

Push Notifications in Oracle APEX enable real-time messaging to users’ devices via Progressive Web App (PWA) capabilities. The component responsible for storing messages is:

A. Queue: ThePush Notification Queue(managed internally by APEX and accessible via APIs like APEX_PWA.PUSH_QUEUE) temporarily holds messages scheduled for delivery. When a notification is created (e.g., via APEX_PWA.SEND), it’s added to this queue, awaiting processing by the APEX mail system or an external push service. The queue ensures reliable delivery, even if the user is offline temporarily, as messages are dispatched once connectivity is restored.

B. Application: The application defines the PWA settings and logic but doesn’t store messages; it’s the container, not the storage mechanism.

Page Designer’s layout modes under Utilities adjust the workspace:

A. Two Pane: Splits into two vertical sections (e.g., tree and properties), ideal for focusedediting.

B. Three Pane: Adds a third section (e.g., tree, grid, properties), offering a balanced view for complex pages.

C. Four Pane: Not available; APEX limits to three for usability.

Faceted search pages in APEX provide dynamic filtering. The true statements are:

Faceted Search supports the ability to filter columns storing multiple values: Facets canhandle multi-value columns (e.g., comma-separated lists or JSON arrays) using appropriate SQL (e.g., INSTR or JSON_TABLE), enabling complex filtering scenarios like tags or categories.

Facets map to specific database columns: Each facet is tied to a column in the underlying query (e.g., DEPTNO or JOB), ensuring data-driven filtering.

Multiple charts are not visible in the same region: False; multiple facets can display charts within the same region, depending on settings.

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.

The "Generate Text with AI" Dynamic Action uses Generative AI to:

Draft an email: Creates text content like emails based on prompts.

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).

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.

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."

TheShow AI Assistant Dynamic Actionin Oracle APEX triggers the display of the AI Assistant interface. To customize the first message users see:

Welcome Message: This attribute in the Property Editor defines the initial text displayed when the AI Assistant appears. Setting it to "How may I help you today?" ensures this exact phrase greets users, enhancing user experience by setting a friendly tone. It’s a static, developer-defined string, distinct from AI-generated responses.

Initial Prompt: This attribute defines the starting input or context sent to the AI model, not the visible message shown to users. It’s typically hidden and used to guide the AI’s behavior (e.g., "Act as a support agent").

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.

AnInteractive Gridis the report type that supports searchable, customizable data display withinline editingat runtime using mouse or keyboard. Interactive Reports are searchable and customizable but lack inline editing. Classic Reports are static, and Smart Filters is a component, not a report type.

To run multiple processes in the background:

D. Execution Chain: This process type allows chaining multiple processes (e.g., PL/SQL, REST calls) to execute sequentially or conditionally in the background, managed via the Process Chain framework. It’s ideal for complex, asynchronous tasks (e.g., batch updates).

A. Execute Code: Not a process type in APEX; likely a misnomer.

B. Execute Server-side Code: Runs a single PL/SQL block synchronously, not multiple background tasks.
