The command used to establish VTP (VLAN Trunking Protocol) password security is structured to be straightforward and adheres to Cisco's command line syntax. The command "vtp password WORD" allows you to set a password that will be used between VTP peers within the same management domain. This password is essential for maintaining the integrity of the VTP information being exchanged to avoid unintended changes in VLAN configurations due to unauthorized devices.

When configuring VTP, specifying a password creates a secure environment where only the devices sharing the same password can participate in VTP communication. This adds a layer of security, ensuring that configurations such as VLAN changes are propagated only among trusted devices.

In contrast, other options do not align with the correct syntax or command structure of Cisco's IOS. For example, while "configure vtp password" seems plausible, it is not a valid command as it does not follow the correct IOS command structure. Similarly, "set vtp password WORD" and "vtp password-set WORD" are not recognized Cisco commands and would not execute successfully in the command-line interface.
