An Interactive Report should allow end users to save private report settings (filters, highlights, and column order) without affecting other users. What feature enables this?

A developer uses a report region with this query: "select * from emp where ename = '" || :P30_ENAME || "'" (concatenation inside the SQL source). Security review flags this as a SQL injection risk. What is the best remediation in APEX?

A developer creates a form page based on a table and adds a new required column to the table later. Users can now submit the form without providing that new column value, and inserts fail in the database with a NOT NULL error. What is the best fix in APEX?

You are integrating APEX with a REST service that requires an OAuth 2.0 bearer token. Multiple pages call this service and you want centralized credential management and token handling. Which APEX feature should you use?

A security review finds that a Classic Report region is vulnerable because its SQL is built by concatenating user input into the WHERE clause in a PL/SQL function returning SQL. What is the best remediation in APEX/Oracle?

In a multi-tenant APEX environment, you must ensure that a set of applications share common authentication and authorization behavior, and that changes can be rolled out consistently without editing each application individually. Which architecture is most appropriate?
