Strategies to help you tackle Oracle APEX Cloud Developer Professional exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for Oracle APEX Cloud Developer Professional
ORDS (Oracle REST Data Services), formerly known as APEX Listener, acts as a middle-tier web server that maps HTTP(S) requests from browsers to the Oracle Database where APEX resides. It translates browser requests into database calls and returns responses. Option A describes the database itself where APEX is installed. Option C describes the APEX development environment interface. Option D is a database security function, not the primary purpose of ORDS.
Using APEX collections allows you to temporarily store detail records in session state without committing them to the database. When the master record is saved, you can process the collection data along with the master record in a single transaction. Option A would result in independent transactions. Option C would make data manipulation complex and doesn't prevent immediate commits. Option D with automatic DML would commit detail changes immediately, not meeting the requirement.
The V() function is the recommended PL/SQL function to retrieve application item values in dynamic SQL contexts. It returns the value as a VARCHAR2. Option A is not a valid APEX_UTIL function. Option C is incorrect syntax for accessing application items. Option D uses bind variable syntax which works in static SQL but is not the standard approach for application items in PL/SQL procedures.
IP address restrictions should be implemented at the ORDS level (or web server level) before requests reach the APEX engine. This provides the most efficient and secure filtering as unauthorized requests are blocked early in the request chain. While Option A could work, it's less efficient and secure as the request has already reached APEX. Option B doesn't provide IP restriction functionality. Option D would be inefficient to maintain across all pages and doesn't prevent access to other application resources.
APEX Web Credentials are designed specifically for storing authentication credentials for external services, including OAuth 2.0. When defined, they can be directly associated with REST Data Sources, handling token management automatically. Option A (database links) is for database-to-database connections, not REST APIs. Option C specifies basic authentication which doesn't match the OAuth 2.0 requirement. Option D (custom authentication schemes) is for authenticating users into APEX, not for outbound API calls.
