Explanation: The Cisco IOS Resilient Configuration feature maintains a secure working copy of the router IOS image file and a copy of the running configuration file. The secure boot-image command functions properly only when the system is configured to run an image from a flash drive with an ATA interface. The secure boot-config command has to be used repeatedly to upgrade the configuration archive to a newer version after new configuration commands have been issued. A snapshot of the router running configuration can be taken and securely archived in persistent storage using the secure boot-config command.
