Zorluk: OrtaConfiguration and Change Management

A network engineering team is preparing to modify Access Control Lists (ACLs) across core datacenter routers to restrict outdated management protocols and enforce secure logging. Before executing the modifications during the scheduled maintenance window, which TWO of the following tasks must be completed as part of the standard change management workflow? (Select TWO.)

  1. Document a detailed rollback plan specifying precise procedures and conditions for reverting the ACL modifications.Cevap
  2. Submit the proposed changes for formal review and approval by the Change Advisory Board (CAB) prior to execution.Cevap
  3. C
    Bypass pre-implementation sandbox testing and apply changes directly to production routers to minimize maintenance window duration.
  4. D
    Reconfigure internal router management interfaces with APIPA (169.254.x.x) addresses to maintain out-of-band administrative access.

Cevap

The engineering team must document a detailed rollback plan and obtain formal approval from the Change Advisory Board (CAB) prior to executing the change.
Standard change management protocols require non-emergency network modifications to undergo formal review by the Change Advisory Board (CAB) to assess potential business impact and scheduling. Additionally, every Request for Change (RFC) must include a fully articulated rollback plan to quickly restore original network operations should issues arise during execution.

Adım Adım Çözüm

1
Identify key requirements of the formal Change Management process for network modifications.
Standard change management workflows mandate thorough risk evaluation, preliminary testing, explicit rollback procedures, and official authorization.
Ensures minimal disruption to production business operations and establishes clear accountability for infrastructure updates.
2
Evaluate the proposed operational steps against change management standards.
Documenting a rollback plan and securing CAB authorization represent essential risk-mitigation and approval controls.
CAB approval ensures cross-functional review of potential impacts, while a detailed rollback plan guarantees rapid recovery if implementation fails.
