Zorluk: KolayConfiguration and Change Management

A company is planning to modify the access control lists (ACLs) on its main gateway router to accommodate a new internal service. Before submitting the Request for Change (RFC) to the Change Advisory Board (CAB), which element is most critical to include in the proposal to minimize potential downtime if the modification causes unexpected network instability?

  1. A validated rollback plan detailing steps to restore the previous configurationCevap
  2. B
    A schedule to execute a full differential backup restoration on all client workstations
  3. C
    A request to bypass sandbox testing and apply the change during peak usage hours
  4. D
    A temporary reconfiguration of client IP addresses to APIPA assignments

Cevap

A validated rollback plan detailing steps to restore the previous configuration
The correct answer emphasizes a validated rollback plan. In formal change management processes, every Request for Change (RFC) must include an explicit rollback strategy detailing how to quickly revert systems to their original baseline configuration if the implementation fails or triggers unexpected downtime.

Adım Adım Çözüm

1
Identify the primary purpose of a Request for Change (RFC) in configuration management
Recognize that changes carry inherent risk to network availability
RFCs must document risk mitigations prior to approval and implementation
2
Evaluate the necessary components designed to recover from a failed change
Determine that a predefined and tested rollback plan enables rapid recovery
Having explicit instructions to restore the last known good configuration minimizes downtime if unexpected outages occur
