Question 185 - 350-601 discussion

The statement that applies to a Cisco Nexus 5600 Series switch when performing a rollback is that errors are skipped when an atomic rollback type is triggered. An atomic rollback is a type of rollback that implements the checkpoint configuration only if no errors occur during the process. If any errors are encountered, the rollback is aborted and the running configuration is restored to its previous state. This ensures that the switch does not end up in a partially configured or inconsistent state. The other statements are not true because:

A user who is assigned to the network-operator user role cannot perform a rollback. The network-operator user role has read-only access to the switch and cannot modify the configuration. To perform a rollback, the user must have the network-admin or vdc-admin user role.

The configuration rollback functionality is not disabled when FCoE is enabled. The rollback feature is supported on all Cisco Nexus 5600 Series switches regardless of the FCoE configuration. However, some FCoE-related commands may not be rolled back due to dependencies or conflicts with other features.

A system checkpoint is not generated automatically when the running configuration is saved to NVRAM. A system checkpoint is a predefined checkpoint that contains the last saved configuration of the switch. A system checkpoint is created or updated only when the user explicitly saves the running configuration to the startup configuration using the copy running-config startup-config command or its alias, copy run start.Reference: For more details on how to configure and use the rollback feature on a Cisco Nexus 5600 Series switch, please refer to the following resources:
