CSI CSI Change Management & Deployment 1 — Questions and Answers
Question 1: What is the primary goal of a Change Advisory Board (CAB) in IT change management?
- To approve annual budgets
- To review and authorize changes to minimize risk to live systems (Correct answer)
- To manage employee performance reviews
- To design system architecture
Correct answer: To review and authorize changes to minimize risk to live systems
A CAB evaluates proposed changes for risk and impact, then authorizes or rejects them to protect production stability.
Question 2: A 'rollback plan' in a deployment strategy is used to:
- Increase system capacity
- Revert to the previous stable state if a deployment fails (Correct answer)
- Document new features for end users
- Archive old version source code
Correct answer: Revert to the previous stable state if a deployment fails
A rollback plan defines the steps to restore the previous working state quickly if a new deployment causes failures.
Question 3: Which deployment strategy releases a new version to a small subset of users before a full rollout?
- Big bang deployment
- Canary deployment (Correct answer)
- Hot standby deployment
- Cold standby deployment
Correct answer: Canary deployment
Canary deployments route a small percentage of traffic to the new version, limiting exposure and enabling early detection of issues.
Question 4: A 'blue-green deployment' maintains two identical environments (blue and green) primarily to:
- Reduce licensing costs by sharing resources
- Enable instant rollback by switching traffic back to the idle environment (Correct answer)
- Support two different geographic regions simultaneously
- Run A/B testing for UX design changes
Correct answer: Enable instant rollback by switching traffic back to the idle environment
Blue-green deployments allow near-zero-downtime releases and instant rollback by keeping the previous environment live until the new one is validated.
Question 5: In ITIL change management, an 'emergency change' is characterized by:
- Requiring the longest approval lead time
- Needing expedited approval to resolve a critical incident or security vulnerability quickly (Correct answer)
- Being planned more than six months in advance
- Requiring no approval at all
Correct answer: Needing expedited approval to resolve a critical incident or security vulnerability quickly
Emergency changes bypass normal approval timelines to address urgent production failures or critical security issues, but are reviewed retrospectively.
Question 6: What does a 'configuration management database' (CMDB) track in a CSI project?
- Employee vacation schedules
- All IT assets and their relationships, including software versions and integration dependencies (Correct answer)
- Customer purchase histories
- Marketing campaign performance
Correct answer: All IT assets and their relationships, including software versions and integration dependencies
A CMDB records configuration items (CIs) and their interdependencies, enabling impact analysis before making changes.
