Which NX-OS command is used to display the boot variable configuration?

'display boot' is a command syntax from Huawei VRP network operating systems - Cisco NX-OS uses 'show' as the standard verb for all information display commands, not 'display'.

'open boot' is not a valid command verb in NX-OS - NX-OS does not use 'open' for displaying or interacting with boot configuration.

'show config' is not a standard NX-OS command for boot variables - the relevant configuration display commands are 'show running-config' or 'show startup-config', neither of which is specific to boot image settings.

The 'show boot' command on Cisco NX-OS displays the boot variable configuration including the current boot image path and next-boot settings, giving administrators a quick way to confirm which NX-OS image the switch will load after a reload before committing to the change.
