CPHIMS CPHIMS System Development Life Cycle 5 — Questions and Answers
Question 1: Which testing phase verifies that the system performs acceptably under expected and peak load conditions?
- Unit testing
- Regression testing
- Performance/load testing (Correct answer)
- Smoke testing
Correct answer: Performance/load testing
Performance and load testing assess system response times and stability under simulated real-world and peak user volumes.
Question 2: A 'go/no-go' decision meeting held before a system go-live is used to?
- Finalize vendor contracts
- Determine whether the system is ready for production deployment (Correct answer)
- Assign post-go-live support roles
- Complete user acceptance sign-off
Correct answer: Determine whether the system is ready for production deployment
A go/no-go meeting formally evaluates readiness criteria and makes the decision to proceed with or delay the production launch.
Question 3: In the SDLC, which activity ensures that system documentation remains current after the system goes live?
- Maintenance and operations (Correct answer)
- Requirements gathering
- Feasibility study
- Design review
Correct answer: Maintenance and operations
The maintenance and operations phase includes updating documentation, applying patches, and managing system changes over the system's life.
Question 4: Which practice helps prevent unauthorized changes to production code by requiring a second reviewer to approve code before deployment?
- Pair programming
- Code review/peer review (Correct answer)
- Waterfall gating
- Regression testing
Correct answer: Code review/peer review
Code peer review requires a second developer to review and approve changes before they are merged or deployed to production.
Question 5: The CPHIMS exam expects HIT professionals to understand that the 'V-model' of SDLC pairs each development phase with a corresponding?
- Design document
- Testing phase (Correct answer)
- Budget review
- User story
Correct answer: Testing phase
The V-model pairs each development phase (requirements, design, coding) with a corresponding testing phase to validate that phase's outputs.
Question 6: Which risk mitigation strategy involves creating a detailed plan to restore operations if a go-live fails?
- Contingency/rollback plan (Correct answer)
- Business impact analysis
- Risk register
- Lessons learned log
Correct answer: Contingency/rollback plan
A contingency or rollback plan defines the steps to revert to the previous system if the new implementation fails critically.
Question 7: During which SDLC phase is the system's total cost of ownership (TCO) FIRST estimated?
- Design
- Testing
- Planning/analysis (Correct answer)
- Maintenance
Correct answer: Planning/analysis
TCO is first estimated during the planning or analysis phase as part of the feasibility study and business case development.
