Oracle APEX Cloud Developer Professional 認定 1Z0-771 試験問題 (Q14-Q19):

質問 # 14
Which two Query Source types can be used to create a dynamic LOV?

A. SQL Query
B. Select List
C. Function Returning SQL Query
D. Procedure

正解：A、C

解説：
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) executed at 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).
Select List: This is a UI component, not a query source type for defining an LOV.
Dynamic LOVs enhance user interaction by providing real-time, data-driven options, critical for forms and filters.

質問 # 15
Which two tasks can be performed by the APEX Assistant when you create an application using the "Create App using Generative AI" option?

A. Create the application blueprint.
B. Update the App icon with a custom image.
C. Add a Dashboard page.
D. Create a Generative AI service.

正解：A、C

解説：
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.
Update the App icon: While app icons can be customized manually post-creation, this is not an automated task performed by APEX Assistant during the generative process.
This feature streamlines development by interpreting intent and building functional components, saving significant time compared to manual creation.

質問 # 16
Which two statements are true about the APEX_MAIL API?

A. You can receive emails using the APEX_MAIL package in an Oracle APEX application.
B. The APEX_MAIL package supports sending emails only to Oracle database users.
C. You can add files as attachments to your emails using the APEX_MAIL package.
D. You can send emails using the APEX_MAIL package from an Oracle APEX application.

正解：C、D

解説：
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).
D . Only to Oracle database users: False; emails can go to any valid address, not just database users.
Pitfall: Ensure the mail queue is processed (APEX_MAIL.PUSH_QUEUE) for timely delivery.

質問 # 17
You must create a single master detail page where users can select a row in the master region and see the corresponding details in the detail region. Users must also interact with the master or the detail without leaving the page. Which type of master detail implementation should you use?

A. Side by Side
B. Stacked
C. Drill Down

正解：A

解説：
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.
B . Stacked: Master and detail are vertically stacked, but interaction is less fluid than side-by-side due to scrolling, though still on one page. Side-by-side is preferred for its clarity and accessibility.
Pitfall: Ensure the detail region's "Server-side Condition" uses the master's selected key (e.g., P1_ID).

質問 # 18
What happens when you regenerate credentials for Push Notifications in Oracle APEX?

A. Push Notifications will be disabled for the application.
B. Existing Push Subscriptions for the application will be invalidated.
C. A new notification server must be created.

正解：B

解説：
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.
C . Disabled for the app: False; notifications remain enabled but won't work for old subscriptions until re-established.
Technical Insight: Regeneration updates APEX_PWA_VAPID_PUBLIC_KEY and APEX_PWA_VAPID_PRIVATE_KEY, triggering a subscription refresh cycle.
Use Case: Security breach requires key rotation.
Pitfall: Users must re-opt-in, potentially losing some subscribers.
