A network engineering team plans to reconfigure VLAN trunking and update Spanning Tree Protocol priorities across campus core switches during an upcoming maintenance window. The lead engineer is finalizing the formal change control documentation for submission to the Change Advisory Board (CAB). Which of the following components must be included in the documentation to ensure the team can safely undo modifications if an unexpected broadcast storm occurs during implementation?
- A detailed rollback plan outlining step-by-step restoration procedures and quantitative failure threshold triggers.Cevap
- BAn execution script designed to modify switch priorities before documenting the current baseline topology.
- CA system restoration strategy relying exclusively on differential configuration backups without keeping the last full baseline backup.
- DA TACACS+ authentication policy update intended to encrypt Layer 2 trunk frame headers during the maintenance window.
Cevap
A detailed rollback plan outlining step-by-step restoration procedures and quantitative failure threshold triggers.
In standard change management protocols, any high-impact network change submitted to a Change Advisory Board must include a robust rollback plan. This plan details precise back-out steps and specific criteria (such as packet loss or broadcast traffic thresholds) that dictate when to abort implementation and restore the known-good baseline.
