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

Declarative options for downloading BLOB/CLOB content include:

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

In Oracle APEX Workflow, onlyone instanceof a workflow can exist in the "In Development" state at a time. This ensures that developers work on a single draft version before publishing it. Multiple instances are allowed in other states (e.g., "Published"), but not during development.

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").

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.

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.

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).

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.

The Data Workshop utility in APEX is designed to load and unloadtable data only, not other schema objects like procedures or views. Option A is false because XLSX files with multiple worksheets are supported (each worksheet can be mapped to a table). Option B is incorrect as it’s limited to table data. Option D is partially true but not the most precise answer, as "multiple tables at a time" depends on the process, whereas C is universally accurate.

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.

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.

Authorization Schemes in APEX can be evaluated at:

Once per page view: Checks authorization each time a page is rendered.

In an Interactive Grid, the "Save Report" functionality allows end users to save customizations (e.g., filters, column order). The available options are:

Private: Saved for the individual user only, visible only to them.

Public: Saved and shared with all users of the application, if permitted by the developer.

Validation errors in APEX default to both inline (next to the item) and notification (top of page):

C. Setting Display Location to Inline in Notification: In the validation’s properties, changing "Display Location" to "Inline in Notification" ensures the error appears only in the notification area, suppressing inline display. This centralizes feedback for a cleaner UI.

A. Removing Associated Item: Breaks the validation’s link to P1_SALARY, stopping it entirely.

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 APEX_MAIL API facilitates email functionality:

A. You can add files as attachments: Using APEX_MAIL.ADD_ATTACHMENT (e.g., APEX_MAIL.ADD_ATTACHMENT(p_mail_id, p_attachment, p_filename)), you can attach BLOBs (e.g., PDFs) to emails.

C. You can send emails: APEX_MAIL.SEND (e.g., APEX_MAIL.SEND(p_to => 'user@example.com', p_body => 'Hello')) sends emails from APEX, leveraging the configured mail server.

B. You can receive emails: False; APEX_MAIL is send-only; receiving requires custom integration (e.g., IMAP).
