Which result is of securing the Cisco IOS image by use of the Cisco IOS image resilience feature?
A.

B.
The Cisco IOS image file will not be visible in the output from the show flash command.
C.
The show version command will not show the Cisco IOS image file location.
D.
The running Cisco IOS image will be encrypted and then automatically backed up to a TFTP server.
Explanation/Reference:
Answer: B
The IOS image resilience feature doesn’t encrypt or backup the IOS… it just hides it. It
does this by removing it from the directory listing when you issue the “show flash”
command. The command to enable this feature is “secure boot-image”.
