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

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.

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.

When creating a faceted search page via the Create Page Wizard, the default report type is anInteractive Report. This pairs with the faceted search region to provide a searchable, filterable, and customizable report, leveraging the facets for dynamic filtering.

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).

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.

In Oracle APEX, when configuring search functionality (e.g., in reports or faceted search), "Oracle Text" refers to a specific search type leveraging the Oracle Text engine. This is a powerful full-text search capability built into Oracle Database, supporting keyword-based searches, fuzzy matching, and indexing.

Standard: A basic SQL-based search (e.g., LIKE), not tied to Oracle Text.

List: Not a search type; it might refer to a UI component or LOV, not a search mechanism.

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.

Declarative options for downloading BLOB/CLOB content include:

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

Workflow parameters and page items in APEX support:

B. NUMBER: For numeric values (e.g., 123.45), used in calculations or IDs.

C. CLOB: For large text (e.g., descriptions), stored as character large objects.

D. VARCHAR: For variable-length strings (e.g., EMPLOYEE_NAME), capped at 4000 characters in most cases.

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.

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).

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.
