Which of the following scenarios represents a violation of the 'Segregation of Duties' principle in the context of IT change management?

Answer options:

The QA team performs both unit testing and regression testing.

The database administrator (DBA) performs backups and restores.

The programmer who wrote the code also migrates it to the production environment.

The system administrator creates user accounts and resets passwords.

How to approach this question

Look for the combination of 'Development' (writing code) and 'Operations' (deploying to production).

Full Answer

C.The programmer who wrote the code also migrates it to the production environment.✓ Correct

Allowing programmers to migrate their own code to production removes the independent check required to prevent unauthorized or untested code from entering the live system.

Common mistakes

Thinking QA doing multiple tests is a conflict.
