Oracle APEX Cloud Developer Professional Intermediate Practice Exam: Medium Difficulty 2025

You are developing an APEX application where multiple workspaces need to share common LOV queries and validation logic. The shared components must be centrally maintained and automatically available to all workspaces. What is the most appropriate solution?

An APEX application requires a page that displays master-detail data where users can update multiple detail records simultaneously and submit all changes in a single transaction. Which page design approach best meets this requirement?

You need to implement a complex business validation that checks data across three different tables before allowing an insert operation. The validation logic is used in multiple APEX pages and may be reused in future batch processes. Where should this validation logic be implemented?

Your application has an Interactive Report where users need to filter data based on their department, but they should never see data from departments they don't have access to, even if they manipulate URL parameters. How should you implement this security requirement?

You are building a master form page with multiple child Interactive Grids. When a user saves the master record, all changes in the child grids should be committed in the same transaction. If any child record fails validation, the entire transaction should roll back. What is the correct implementation approach?

An Interactive Report displays employee data with a column containing salary information. Users should be able to sort and filter on all columns except salary, which should be displayed but not interactive. Additionally, certain users should not see the salary column at all. What combination of features accomplishes this requirement?

You need to create a PL/SQL process that sends notification emails when certain records are updated in your APEX application. The email sending might take several seconds, and you don't want users to wait for this operation to complete. What is the best approach?

Your APEX application uses custom authentication, and you need to implement a 'Remember Me' feature that keeps users logged in across browser sessions for up to 30 days. Which combination of features should you implement?

You have an Interactive Report with a SQL query that joins five tables and includes several calculations. Users report that the report is slow to load. After reviewing the query execution plan, you find it's optimal. What APEX-specific techniques should you consider to improve perceived performance?

Your application needs to generate a complex PDF report using data from multiple tables with custom formatting and images. The report generation takes about 15 seconds. Users should be able to request the report and continue working in the application while it's being generated, then download it when ready. Which architecture best supports this requirement?
