A senior voice engineer is preparing a formal change request to migrate the organization's central Voice over IP (VoIP) Private Branch Exchange (PBX) to a new cloud-hosted platform. To ensure compliance with enterprise change management governance, the engineer must submit the documentation for Change Advisory Board (CAB) review. Which of the following components MUST be included in the submitted change request prior to authorization? (Select TWO).
- A detailed risk assessment identifying potential operational impacts and service disruptions during the migration windowAnswer
- A documented rollback plan specifying exact steps to restore the legacy PBX environment if migration targets failAnswer
- CA formal pre-approval waiver exempting the engineering team from conducting post-implementation functionality testing
- DAn export of administrative service account credentials attached directly to the public ticket for auditor inspection
Answer
The formal change request must include a detailed risk assessment outlining potential operational impacts and a documented rollback plan detailing procedures to revert back to the original functional state.
A comprehensive change request must explicitly document the risk assessment (evaluating potential operational impacts and business risk) and a comprehensive rollback plan (providing step-by-step instructions to revert to a stable baseline state if implementation fails).
