To prevent prolonged outages and to satisfy regulatory audit requirements, a network administrator is creating a policy for backing up the configurations of all routers and switches. Which of the following backup strategies BEST follows industry best practices for configuration management?
Perform manual backups only when a device experiences a failure that requires troubleshooting.
Save the initial baseline configuration and update it only when hardware is permanently replaced.
Schedule automated configuration backups to occur only once per month during a planned maintenance window.
Configure the management platform to automatically archive the running configuration immediately after every authorized change.
Industry and vendor guidance recommends capturing an automatic, event-driven backup immediately after each authorized configuration change. Doing so guarantees that the latest known-good state is available if a device fails, simplifies troubleshooting by providing a complete change history, and meets compliance requirements that mandate accurate configuration records. Periodic monthly backups, manual post-failure backups, or rarely updated baseline files leave significant gaps and may violate policy.
