Oracle APEX Cloud Developer Professional Practice Exam 2025: Latest Questions

You create a report page based on a table and want the end users to be able to filter and sort the results without additional coding. Which APEX component is the most appropriate choice?

A user selects a row in an Interactive Grid and clicks a custom button to navigate to a detail page. You need to pass the selected row's primary key to the target page item P10_ID. What is the recommended approach?

An application uses Oracle APEX authentication. You need to restrict access to an entire page so only users assigned the role MANAGER can view it. What is the best APEX feature to use?

You need to centralize the database connection credentials and parsing schema for multiple APEX applications in the same workspace, and you want to avoid duplicating configuration per application. Which concept provides this at the workspace level?

A page process inserts into ORDER_HEADER and must capture the generated ORDER_ID to insert related ORDER_LINES. Which approach is most reliable and maintainable in APEX?

You have a REST Data Source that calls an external service returning JSON. You need to display a report and also use the same response in multiple pages without repeating configuration. What is the best practice in APEX?

Users report that a page item value is sometimes overwritten unexpectedly after partial page refreshes. The page uses a Dynamic Action that executes a PL/SQL block and sets item values. Which troubleshooting step is MOST likely to identify the cause?

You want to implement row-level security so that users can only see and update rows they own across multiple pages and reports. Which approach is recommended to ensure consistent enforcement even if a developer later creates a new report?

Your application has an Interactive Grid used for editing. Users intermittently get 'ORA-00060: deadlock detected' when multiple users update different rows. The grid is based on a view that joins ORDER_HEADER and ORDER_LINES. What design change is MOST likely to resolve this while preserving editable behavior?

A security review finds that some pages build SQL dynamically using concatenated page item values (for example, WHERE clause fragments) to support flexible filtering. You must keep flexibility but eliminate SQL injection risk. What is the best remediation approach in APEX?

You need to display a list of 25,000 customer records in an Interactive Report. Users will frequently filter and sort on multiple columns. What is the best practice to ensure good performance and scalability?

A page process is supposed to run only when the user clicks the "Approve" button. However, it runs even when the user clicks "Cancel". Which configuration most directly fixes this?

In an APEX application, where are application-level items (for example, G_USER_ROLE) stored and maintained at runtime?

You are implementing a "Create Order" form. After successful submit, the user should be redirected to the Order Details page and see a single success message. What is the recommended approach?

A report query uses a page item P10_DEPTNO to filter rows. When the item is changed via a dynamic action (without page submit), the report does not refresh with the new filter. What is the most appropriate fix?

You are asked to allow business users to download and upload data through a spreadsheet-like interface while enforcing validations and using server-side processing for changes. Which APEX component best fits this requirement?

You need to expose a REST endpoint that returns JSON for a report, and it must enforce the same authorization rules as the APEX app. Which approach best aligns with APEX security best practices?

An APEX page process performs INSERTs into multiple tables and then calls an external web service. If the web service call fails, none of the database changes should be saved. What is the best approach?

Your application uses Friendly URLs and deep-linking. After enabling a strict authorization scheme, users report that bookmarked links sometimes redirect to the home page without explanation. What is the most likely cause and best remediation?

You must implement row-level security so users can only see and modify rows belonging to their business unit across all pages (reports, forms, and REST-like data access). The requirement is to enforce this as centrally as possible. What is the strongest approach?

You want to ensure that a user can only update rows in an Interactive Grid that belong to their department. The department is determined at runtime from the user’s session (for example, an application item). Which approach is the most secure and maintainable?

A page has a Select List item P10_STATUS and a report region based on a SQL query using :P10_STATUS. When the user changes the status, the report does not refresh and still shows the previous results. What is the most likely missing configuration?

You are building a REST Data Source in APEX to call an external service that requires an API key. You must prevent the key from being exposed in page source, browser tools, or exported application metadata. What is the recommended approach?

An APEX application uses an Interactive Report based on a join across multiple tables. Users complain the report is slow. Which change is most likely to improve performance without reducing functionality and while keeping the SQL manageable?

You need to implement a multi-step “wizard” that collects data across several pages, and the user must be able to go back and forward without losing entered values. You also want to avoid writing custom tables for temporary storage. Which APEX feature best fits this requirement?
