Oracle Oracle APEX Cloud Developer Professional 1z0-771 Exam Dumps: Updated Questions & Answers (October 2025)

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.

To send push notifications to all subscribed users, you must:

Enable push notifications at the application level (a prerequisite).

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

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

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.

The Map Region in APEX supports spatial data via:

GeoJSON: A JSON-based standard for geographic data (e.g., points, polygons).

SDO_GEOMETRY: Oracle’s native spatial data type for storing geometry (e.g., SDO_GEOMETRY(2001, 4326, SDO_POINT_TYPE(-122, 37, NULL), NULL, NULL)).

Latitude/Longitude: Separate columns for lat/long coordinates, mapped to points.

Declarative options for downloading BLOB/CLOB content include:

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

By default, faceted search can "batch" changes, requiring an "Apply" button click to filter the report. To enable automatic filtering:

Disable the Batch Facet Changes attribute: In Page Designer, under the Faceted Search region’s Attributes, setting "Batch Facet Changes" to "No" ensures the report refreshes immediately when a facet value is selected, improving responsiveness. This triggers an AJAX call to update the report without a manual submit.

Show Facet Name: This controls facet label visibility, unrelated to filtering behavior.

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.

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).

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.
