What command in Device > Setup > Operations would provide the most operationally efficient way to achieve this outcome?
A . save named configuration snapshot
B. export device state
C. export named configuration snapshot
D. save candidate config

Answer: A

Explanation:

Export Named Configuration Snapshot This option exports the current running configuration, a candidate configuration snapshot, or a previously imported configuration (candidate or running). The firewall exports the configuration as an XML file with the specified name. You can save the snapshot in any network location. These exports often are used as backups. These XML files also can be used as templates for building other firewall configurations.
