Question 1 of 30

Following a critical vSphere cluster outage directly attributed to an unvalidated network configuration change during a scheduled maintenance window, the operations team successfully restored services through intensive troubleshooting. However, the incident revealed a systemic weakness in how network infrastructure modifications are introduced into the production environment. Considering the need to demonstrate adaptability and flexibility in response to operational failures, which strategic adjustment would most effectively address the root cause and prevent similar occurrences in future maintenance cycles?

Implement a mandatory, multi-stage validation process for all network configuration changes, including pre-production testing in a simulated environment and a documented, reversible rollback plan for every deployment.
Enhance inter-team communication protocols to ensure all network changes are communicated to virtualization and security teams at least 48 hours in advance of implementation.
Reassign responsibilities within the operations team to create a dedicated network troubleshooting sub-group to expedite resolution of future network-related incidents.
Deploy advanced network monitoring tools capable of real-time anomaly detection to provide earlier warnings of potential configuration drift or misapplication.
