To comply with standard CompTIA A+ change management procedures, arrange the following operational phases in the correct chronological order from first to last.
- 1Define the purpose and scope of the migration while conducting a risk analysis of operational impact.
- 2Formulate a comprehensive plan for change and construct a fully documented rollback plan.
- 3Submit the change request documentation to the Change Advisory Board (CAB) for authorization.
- 4Issue end-user notifications detailing the upcoming maintenance window and anticipated service impact.
- 5Perform the migration during the scheduled window and complete post-implementation testing.
Cevap
The correct chronological sequence for the change management lifecycle is: 1) Define purpose/scope and conduct risk analysis, 2) Formulate the plan for change and documented rollback plan, 3) Submit the change request to the Change Advisory Board (CAB) for authorization, 4) Issue end-user notifications detailing the maintenance window, and 5) Perform the migration and complete post-implementation testing.
The standard CompTIA change management workflow mandates that an IT professional first define the scope and conduct a risk analysis. Next, detailed implementation and rollback plans must be authored. Only after these plans are finalized is the proposal submitted to the Change Advisory Board (CAB) for approval. Once authorized, end users are notified of the maintenance window. Finally, the migration is executed and post-implementation testing verifies system stability.
