CSI Change Management & Deployment Flashcards

What is the primary goal of a Change Advisory Board (CAB) in IT change management?

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.

A 'rollback plan' in a deployment strategy is used to:

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.

Which deployment strategy releases a new version to a small subset of users before a full rollout?

Answer: Canary deployment

Canary deployments route a small percentage of traffic to the new version, limiting exposure and enabling early detection of issues.

A 'blue-green deployment' maintains two identical environments (blue and green) primarily to:

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.

In ITIL change management, an 'emergency change' is characterized by:

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.

What does a 'configuration management database' (CMDB) track in a CSI project?

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.
