CISA Practice Question: Which TWO of the following are key controls in…
Which TWO of the following are key controls in the system development life cycle?
⚠ Common exam trap
A common mix-up: candidates confuse 'development methodology' or 'automation tools' with 'controls,' forgetting that controls are governance mechanisms that provide independent verification, segregation, or oversight, not just technical processes or tools.

Correct answer & explanation
✓
Post-implementation review
A post-implementation review is a key control in the SDLC because it systematically evaluates whether the delivered system meets the defined business requirements, security objectives, and performance criteria after deployment. It identifies gaps, operational issues, and lessons learned that feed back into future development cycles, ensuring continuous improvement and compliance with governance frameworks like COBIT.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Post-implementation review
Why this is correct
Ensures system meets objectives and provides feedback.
- ✗
Use of agile methodology
Why it's wrong here
Agile is a methodology, not a control.
- ✓
Segregation of duties between development and operations
Why this is correct
Prevents unauthorized changes.
- ✗
Formal approval of business requirements
Why it's wrong here
While important, it is a requirement validation step, not a key SDLC control (but could be argued; for exact two, A and E are more recognized).
- ✗
Automated deployment tools
Why it's wrong here
Automation is a practice, not a control.
