NEW QUESTION # 32
Which two statements are true about creating and using dynamic actions?
- A. If a client-side condition is defined, the true action will fire when the condition is met.
- B. You can execute JavaScript code by creating a dynamic action.
- C. After you create a dynamic action, you cannot add more true actions.
- D. If no client-side condition is defined, true actions will not fire.
Answer: A,B
Explanation:
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.
No condition, true actions won't fire: False; without a condition, true actions fire unconditionally on the event.
Dynamic Actions are a cornerstone of interactive UIs in APEX.
NEW QUESTION # 33
Which two are prerequisites to use the REST-enabled SQL feature in Oracle APEX?
- A. Install ORDS 19.x or later on the remote Oracle Database.
- B. Create a database link to the remote Oracle Database in the local APEX schema.
- C. Install Oracle APEX in the remote Oracle Database.
- D. REST-enable the schema in the remote Oracle Database by using ORDS.ENABLE_SCHEMA.
Answer: A,D
Explanation:
To use REST-enabled SQL in APEX:
Install ORDS 19.x or later: Oracle REST Data Services (ORDS) must be installed and configured on the remote database.
REST-enable the schema: The schema on the remote database must be REST-enabled using ORDS.ENABLE_SCHEMA to allow SQL execution via REST.
A database link is not required, and installing APEX on the remote database is unnecessary since REST-enabled SQL connects APEX to a remote schema via ORDS.
NEW QUESTION # 34
Which two are valid evaluation points for Authorization Schemes?
- A. Once per page view
- B. Never
- C. Once per session
- D. Once per user
Answer: A,C
Explanation:
Authorization Schemes in APEX can be evaluated at:
Once per page view: Checks authorization each time a page is rendered.
Once per session: Checks once per user session, caching the result.
Once per user and Never are not valid evaluation points in the Authorization Scheme settings.
NEW QUESTION # 35
Which Process type do you use to run multiple processes in the background in APEX?
- A. Execute JavaScript Code
- B. Execute Code
- C. Execute Server-side Code
- D. Execution Chain
Answer: D
Explanation:
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.
C . Execute JavaScript Code: Client-side, not suited for background server processes.
Use case: Chain processes like data validation, logging, and email sending without blocking the UI.
NEW QUESTION # 36
Which API can be used to send Push Notifications immediately in Oracle APEX?
- A. APEX_PWA.PURGE_QUEUE
- B. APEX_PWA.HAS_PUSH_SUBSCRIPTION
- C. APEX_PWA.PUSH_QUEUE
Answer: C
Explanation:
The APEX_PWA package manages Push Notifications:
B . APEX_PWA.PUSH_QUEUE: This procedure forces immediate processing of the Push Notification queue, sending queued messages (added via APEX_PWA.SEND) to subscribed devices without waiting for the default scheduler (e.g., every 5 minutes). Example: APEX_PWA.PUSH_QUEUE; ensures a "Meeting now!" alert goes out instantly.
A . APEX_PWA.HAS_PUSH_SUBSCRIPTION: Checks if a user has an active subscription (returns BOOLEAN), not for sending.
C . APEX_PWA.PURGE_QUEUE: Clears the queue, discarding unsent messages, not sending them.
Technical Insight: PUSH_QUEUE triggers a job to contact the push service (e.g., Firebase), using VAPID keys from the PWA configuration.
Use Case: Urgent alerts (e.g., system outage) need immediate delivery, bypassing delays.
Pitfall: Overuse can strain the server; use judiciously for time-sensitive messages.
NEW QUESTION # 37
Which two statements are true about Oracle APEX?
- A. APEX eliminates middle tier application logic.
- B. You can build interactive reporting apps based on data from disparate systems.
- C. Application definition is not stored in the database.
- D. Running an APEX app needs client software.
Answer: A,B
Explanation:
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.
Application definition not stored in database: False; definitions are stored as metadata in the database (e.g., APEX_APPLICATIONS).
This reflects APEX's database-centric, low-code philosophy.
NEW QUESTION # 38
Which step is mandatory to make an existing Oracle APEX application Progressive Web App (PWA) enabled?
- A. Verify that Friendly URLs are turned on in the Application Definition.
- B. Enable the PWA flag in the Application Definition.
- C. Enable RESTful Web Services in the application.
- D. Add custom JavaScript to support offline functionality.
Answer: B
Explanation:
To enable an existing APEX application as a Progressive Web App (PWA), the mandatory step is:
Enable the PWA flag in the Application Definition: In the Application Definition attributes under "Progressive Web App," setting "Enable PWA" to "Yes" activates PWA features like installability, push notifications, and service worker generation. This is the foundational step, after which optional customizations (e.g., icons, manifest) can be added.
Friendly URLs: While recommended for modern apps, they're not required for PWA functionality.
Custom JavaScript: Optional for offline capabilities, but not mandatory for basic PWA enablement.
RESTful Web Services: Unrelated to PWA features.
This step transforms the app into a PWA, enhancing user experience on mobile and desktop devices with native-like behavior.
NEW QUESTION # 39
What do you achieve by performing the "Refresh Working Copy" task?
- A. Get the latest updates from the Main application.
- B. Update the changes from one Working Copy to another.
- C. Merge the Working Copy changes with the Main application.
Answer: A
Explanation:
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.
B . Update between Working Copies: Not supported; refreshing is Main-to-Working only.
Practical note: Use this to sync collaborative development efforts.
NEW QUESTION # 40
Which two SQL format options does the APEX Assistant provide when using the "Create Data Model using AI" feature?
- A. MySQL
- B. Quick SQL
- C. Oracle PL/SQL
- D. Oracle SQL
Answer: B,D
Explanation:
The "Create Data Model using AI" feature in APEX Assistant leverages AI to generate data models based on natural language input. The supported SQL format options are:
Quick SQL: A shorthand syntax for defining database objects, which APEX can convert into full DDL.
Oracle SQL: Standard SQL syntax compatible with Oracle Database for creating tables and other objects.
MySQL is not supported as it's specific to a different database system, and Oracle PL/SQL is a procedural language, not a format for defining data models in this context.
NEW QUESTION # 41
Which two statements are true about creating and managing an APEX Workspace?
- A. A workspace can be associated with only one schema.
- B. During workspace creation, you can associate the workspace with an existing database schema.
- C. You can create only two workspaces in an APEX Service (APEX Application Development) instance.
- D. New schemas cannot be created during workspace creation.
Answer: B,D
Explanation:
APEX Workspaces define development environments tied to database schemas:
A . During workspace creation, you can associate the workspace with an existing database schema: In the Workspace creation wizard (via Instance Administration), you select an existing schema (e.g., "HR") to link, enabling access to its objects. This is a standard step, ensuring immediate usability.
B . New schemas cannot be created during workspace creation: APEX doesn't provide a UI to create schemas here; schemas must pre-exist in the database, created via SQL (e.g., CREATE USER).
C . A workspace can be associated with only one schema: False; a workspace can associate with multiple schemas post-creation via "Manage Workspace to Schema Assignments." D . You can create only two workspaces: False; the limit depends on the APEX instance configuration (e.g., cloud service tier), not a fixed number like two.
Use case: Associating existing schemas is key for leveraging pre-built databases.
NEW QUESTION # 42
In your application, you want to display data in a searchable, customizable report that supports inline editing at runtime using the mouse or keyboard. Which report type will you create?
- A. Classic Report
- B. Interactive Report
- C. Smart Filters
- D. Interactive Grid
Answer: D
Explanation:
An Interactive Grid is the report type that supports searchable, customizable data display with inline editing at 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.
NEW QUESTION # 43
The Movies faceted search report is filtered only when the Apply button for a selected facet is clicked. What must be done in the Page Designer so that report filtering is automatically executed when any facet value is selected?
- A. Navigate to the faceted search region Attributes, and turn off the Show Facet Name attribute.
- B. Navigate to the faceted search region Attributes, and disable the Batch Facet Changes attribute.
- C. Navigate to each facet and then in the Property Editor, turn on Client-Side Filtering.
Answer: B
Explanation:
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.
Client-Side Filtering: This applies to Interactive Reports/Grids, not faceted search regions, and isn't the correct solution here.
This adjustment enhances the user experience by providing instant feedback.
NEW QUESTION # 44
How many instances of a Workflow can exist in the "In Development" state?
- A. Unlimited
- B. 0
- C. 1
Answer: C
Explanation:
In Oracle APEX Workflow, only one instance of 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.
NEW QUESTION # 45
Which two layout modes are available for Page Designer under Utilities?
- A. Three Pane
- B. Four Pane
- C. Single Pane
- D. Two Pane
Answer: A,D
Explanation:
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 focused editing.
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.
D . Single Pane: Not an option; the minimum is two panes.
Developers toggle these via the Utilities menu to optimize screen real estate based on task complexity.
NEW QUESTION # 46
Which statement is true about the Link Column attributes of an Interactive Report?
- A. It is not possible to exclude Link Column.
- B. If you select Link Column, it is always displayed as the last column in the report.
- C. It is not possible to include a custom target in Link Column.
- D. A Link Column cannot be sorted, hidden, or moved by an end user.
Answer: A
Explanation:
The Link Column in an Interactive Report adds a clickable link to each row. The true statement is:
It is not possible to exclude Link Column: Once defined in the report attributes, the Link Column is mandatory and cannot be hidden or excluded via end-user controls (e.g., Column Management). It's always rendered unless removed by the developer.
Custom target: False; custom targets (e.g., URLs, pages) can be defined.
Always last column: False; its position is configurable.
Cannot be sorted/hidden/moved: False; end users can sort or move it, though hiding is restricted.
This behavior ensures consistent navigation in reports.
NEW QUESTION # 47
Which statement is true about importing an existing application into your workspace?
- A. You cannot import an APEX application exported from the latest APEX version to an old APEX version.
- B. The import process does not import the supporting objects defined during the export.
- C. You cannot change the application ID during the import process.
Answer: A
Explanation:
Importing an APEX application involves transferring its definition (exported as a .sql file):
C . You cannot import an APEX application exported from the latest APEX version to an old APEX version: APEX enforces backward compatibility limits. An app exported from 23.2 (latest features like AI Assistants) can't import into 19.2, as older versions lack support for newer metadata (e.g., APEX_AI tables). The import wizard checks the version and rejects incompatible files.
A . You cannot change the application ID: False; the import wizard prompts for a new ID if there's a conflict or if you choose to override.
B . Supporting objects not imported: False; if included in the export (via "Include Supporting Objects"), they're imported (e.g., tables, triggers), unless skipped explicitly.
Technical Insight: Export files contain a version check (e.g., apex_version := '23.2';), causing rejection if the target instance's APEX_VERSION is lower.
Use Case: Moving an app from a dev instance (23.2) to prod (23.2) works, but not to an outdated test instance (19.1).
Pitfall: Always match versions or upgrade the target instance first.
NEW QUESTION # 48
Which component of the Push Notifications feature stores the messages that are ready to be sent?
- A. Subscription
- B. Application
- C. Queue
Answer: C
Explanation:
Push Notifications in Oracle APEX enable real-time messaging to users' devices via Progressive Web App (PWA) capabilities. The component responsible for storing messages is:
A . Queue: The Push Notification Queue (managed internally by APEX and accessible via APIs like APEX_PWA.PUSH_QUEUE) temporarily holds messages scheduled for delivery. When a notification is created (e.g., via APEX_PWA.SEND), it's added to this queue, awaiting processing by the APEX mail system or an external push service. The queue ensures reliable delivery, even if the user is offline temporarily, as messages are dispatched once connectivity is restored.
B . Application: The application defines the PWA settings and logic but doesn't store messages; it's the container, not the storage mechanism.
C . Subscription: Represents user device registrations (stored in APEX_APPL_PUSH_SUBSCRIPTIONS), not the messages themselves. Subscriptions link devices to the app for delivery, not queuing.
Technical Insight: The queue is a database-backed structure, leveraging Oracle's job scheduling (e.g., DBMS_SCHEDULER) to process entries. For example, calling APEX_PWA.SEND(p_message => 'Promo Alert!') adds an entry to the queue, which is then pushed to subscribed devices.
Use Case: A retail app queues a "Sale starts now!" message for 1,000 users, ensuring orderly delivery without overwhelming the server.
Pitfall: If the queue isn't periodically pushed (e.g., via APEX_PWA.PUSH_QUEUE), messages may delay.
NEW QUESTION # 49
Which two statements are true about faceted search pages?
- A. A facet's chart can be seen only in a nonmodal dialog.
- B. Multiple charts are not visible in the same region.
- C. Faceted Search supports the ability to filter columns storing multiple values.
- D. Facets map to specific database columns.
Answer: C,D
Explanation:
Faceted search pages in APEX provide dynamic filtering. The true statements are:
Faceted Search supports the ability to filter columns storing multiple values: Facets can handle 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 facet's chart can be seen only in a nonmodal dialog: False; charts can appear inline or in dialogs, configurable via facet attributes.
This functionality makes faceted search ideal for exploratory data analysis.
NEW QUESTION # 50
An APEX e-commerce application is being used by 50 users. You have a promotional offer, and you need to send a push notification to all the subscribed users on their devices. Which step must be performed in Oracle APEX to achieve this?
- A. Create a REST Data Source to send push notifications to all the subscribed users.
- B. Enable push notifications at the application level and let APEX handle the subscription and delivery process automatically.
- C. Create a Dynamic Action of Send Push Notification type to send push notifications to all the subscribed users.
- D. Create a PL/SQL block to fetch all the subscribed users and send push notifications by using APEX_APPL_PUSH_SUBSCRIPTIONS & APEX_PWA.SEND.
Answer: D
Explanation:
To send push notifications to all subscribed users, you must:
Enable push notifications at the application level (a prerequisite).
Use a PL/SQL block with APEX_APPL_PUSH_SUBSCRIPTIONS to fetch subscribers and APEX_PWA.SEND to send the notifications.
Option A is incorrect as there's no "Send Push Notification" Dynamic Action type. Option B is incomplete as enabling alone doesn't send notifications. Option C is unrelated to push notifications.
NEW QUESTION # 51
What are two reasons to enable the "Used by App Builder" option while creating a Generative AI Server?
- A. To build applications using natural language powered by Generative AI
- B. To author SQL powered by Generative AI
- C. To create a Working Copy of your application
- D. To create a REST-enabled database object
Answer: A,B
Explanation:
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.
Build applications using natural language: Enables natural language prompts to create app components.
Options A and B are unrelated to this setting, as it's specific to AI integration in App Builder.
