A recent set of changes by a Cisco ACI administrator corrupted the APIC cluster. The ACI engineer must restore the configuration of the previous day. The APIC nodes in the cluster can communicate but fail to connect with other networks. The administrator plans to overwrite the entire existing configuration with the backup configuration. Which set of actions accomplishes this task?
Correct Answer: B
Atomic Replace - overwrites existing configuration with imported configuration data. Any objects in the existing configuration that do not exist in the imported configuration are deleted. Objects are deleted from the existing configuration that have children in the existing configuration but do not have children in the incoming imported configuration. For example, if an existing configuration has two tenants, solar and wind, but the imported backed up configuration was saved before the tenant wind was created, tenant soar is restored from the backup but tenant wind is deleted.
