Oracle 1z0-771 Oracle APEX Cloud Developer Professional Exam Practice Test

Theme Styles define visual aspects (e.g., colors, fonts) in APEX:

B. When the Is Public attribute is enabled: Setting "Is Public" to "Yes" allows end users to select from available Theme Styles at runtime (e.g., via a UI switcher), enhancing customization.

A. Control the layout: False; layout is managed by templates and regions, not Theme Styles, which focus on aesthetics.

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."

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.

Key truths about Oracle APEX:

APEX eliminates middle tier application logic: APEX runs entirely within the Oracle Database, using PL/SQL and SQL for logic, bypassing traditional middle-tier servers (e.g., Java EE). This simplifies architecture and boosts performance.

You can build interactive reporting apps based on data from disparate systems: Via REST Data Sources, database links, or ORDS, APEX integrates data from external systems, enabling unified reporting (e.g., combining on-premises and cloud data).

Needs client software: False; APEX is web-based, requiring only a browser.

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.

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.

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 GetCurrentPosition Dynamic Action retrieves geolocation data from the user's device. It supports:

Latitude and Longitude: Returns coordinates as separate numeric values (e.g., lat: 37.7749, lon: -122.4194).

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.

Declarative options for downloading BLOB/CLOB content include:

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

The "Check Syntax" process in APEX, typically used in SQL Workshop or when validating code, authenticates usingDatabase schema credentials. These are the credentials of the schema associated with the APEX workspace (e.g., username/password of the schema like "HR"). This ensures the process has access to parse and validate SQL or PL/SQL against the database objects in that schema.

APEX Workspace Admin credentials: These are for managing workspaces, not executing database-level syntax checks.

Push notifications in Oracle APEX are enabled at theapplication level. This allows the application to register with the Progressive Web App (PWA) framework and manage subscriptions for all end users. Once enabled in the Application Definition under "Progressive Web App" settings, APEX handles the subscription process, and developers can use APIs like APEX_PWA.SEND to send notifications. Enabling at the region, page, or instance level is not supported for this feature.

Theme Styles define visual themes in APEX:

A. When the Is Public attribute is enabled: Setting "Is Public" to "Yes" in Shared Components > Theme Styles allows runtime selection (e.g., via a dropdown in the app UI), letting users switch between styles (e.g., "Vita" to "Vita - Dark").

B. Control layout: False; layout is managed by templates and regions; Theme Styles handle colors, fonts, etc.

Working Copies in APEX allow safe experimentation:

C. Get the latest updates from the Main application: "Refresh Working Copy" (in App Builder > Working Copies) pulls changes from the Main application into the Working Copy, ensuring it reflects the latest state (e.g., new pages, fixes) without overwriting Working Copy changes.

A. Merge with Main: Merging is a separate "Merge Working Copy" task.
