B.

C.
takes a snapshot of the router running configuration and securely archives it in persistent storage

Explanation:
The “secure boot- config ” is a global config command, which takes a copy of the running
configuration and saves it to persistent storage. FYI, persistent storage refers to PCMCIA
ATA disks, not Flash nor NVRAM. Therefore the command only works on systems with
PCMCIA ATA disks installed.
