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.

Declarative options for downloading BLOB/CLOB content include:

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

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).

The requirement is to allow users to pick a single employee (name and ID) from a list tied to the MANAGER_ID column in the EMPLOYEES table, implying a dynamic, searchable selection:

A. Popup LOV: This item type displays a popup window with a searchable list of values, sourced from a SQL query (e.g., SELECT ename, empno FROM employees WHERE empno IN (SELECT DISTINCT manager_id FROM employees)). It returns a single value (e.g., EMPNO) while displaying the name, perfectly meeting the need for a single selection from a related dataset.

B. Switch: A toggle (Yes/No), unsuitable for selecting from a list of employees.

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).

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.

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.

Theme Styles define visual aspects (e.g., colors, fonts) in APEX:

B. When the Is Public attribute is enabled: Setting "Is Public" to "Yes" allows end users to select from available Theme Styles at runtime (e.g., via a UI switcher), enhancing customization.

A. Control the layout: False; layout is managed by templates and regions, not Theme Styles, which focus on aesthetics.

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.
