Explanation

On a Cisco Nexus 6000, pressing Ctrl-Shift-6 within 2 seconds of applying power forces the switch to boot from the protected golden BIOS image.

Common mistakes.

A. Ctrl-Shift-6 is the correct key combination, but 30 seconds is incorrect - the timing window is only 2 seconds after power is supplied to the switch.
B. Ctrl-] is used on some Nexus platforms to interrupt the boot loader, not to select the golden BIOS on the Nexus 6000, and the 2-second window specification is also wrong here.
C. Both the key combination (Ctrl-]) and the timing window (30 seconds) are incorrect for the golden BIOS selection procedure on the Nexus 6000.
