1z0-771 Practice Exam Questions with Answers Oracle APEX Cloud Developer Professional Certification

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 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).

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.

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.

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.

Dynamic Actions in APEX enable responsive behavior:

If a client-side condition is defined, the true action will fire when the condition is met: A condition (e.g., this.browserEvent === 'click') ensures the true action (e.g., Show, Hide) executes only when true, enhancing precision in event handling.

You can execute JavaScript code by creating a dynamic action: The "Execute JavaScript Code" action type allows custom scripts (e.g., alert('Clicked!');), extending functionality beyond declarative options.

Cannot add more true actions: False; multiple true actions can be added post-creation.

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.

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.

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.

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.
