Zorluk: OrtaConfiguration and Change Management

A network engineer is preparing a formal Request for Change (RFC) for an upcoming core router configuration update during a scheduled maintenance window. The Change Advisory Board (CAB) mandates that all high-impact RFCs include provisions to minimize operational downtime in case the update causes unforeseen service disruption. Which of the following components MUST be explicitly defined within the RFC to fulfill this mandatory requirement?

  1. A detailed rollback plan that includes specific back-out procedures and quantitative trigger thresholds.Cevap
  2. B
    An updated baseline configuration document reflecting the target post-implementation state.
  3. C
    A complete differential backup restoration log verified from the previous maintenance period.
  4. D
    An SNMPv3 trap polling profile configured to notify monitoring systems of configuration drift.

Cevap

A detailed rollback plan that includes specific back-out procedures and quantitative trigger thresholds.
A comprehensive rollback plan specifies the step-by-step procedures, timing constraints, and clear trigger conditions required to safely restore the network to its pre-change state if the modification introduces unexpected issues.

Adım Adım Çözüm

1
Identify the core requirement of the Change Advisory Board (CAB) scenario.
The CAB requires a mechanism to mitigate risk and quickly restore service if the proposed change fails.
Standard change management protocol dictates that risk mitigation must be established prior to executing changes.
2
Evaluate the role of a rollback plan within an RFC.
A rollback plan specifies explicit steps, time limits, and trigger conditions to revert changes safety.
Having predefined rollback triggers prevents prolonged outages caused by troubleshooting failed changes live during a tight maintenance window.
