How can you configure VRRP priority on a Cisco router?

1. Using the command 'vrrp GROUP NUMBER priority PRIORITY NUMBER'

2. By modifying the system default priority settings

3. Through the 'ip vrid' command in global configuration mode

4. By setting priority levels directly on individual interfaces

The correct answer is: Using the command 'vrrp GROUP NUMBER priority PRIORITY NUMBER'

The priority for Virtual Router Redundancy Protocol (VRRP) on a Cisco router is configured using the specific command that includes the group number and the desired priority value. This command, 'vrrp GROUP NUMBER priority PRIORITY NUMBER', is entered in the interface configuration mode of the router. When this command is used, it allows the administrator to explicitly define a priority for the virtual router instance. The priority value can range from 1 to 255, with a higher value signifying a higher priority for that particular router in the VRRP group. This is crucial in determining which router will take on the role of the master router—if all other routers within the VRRP group have lower priority settings, the router with the highest priority will assume that role. In contrast, modifying system default priority settings pertains to general configurations and does not provide the granularity needed for specific VRRP configurations. The 'ip vrid' command is not typically associated with standard VRRP configuration on Cisco routers, as it is specific to a different protocol or vendor implementation. Lastly, setting priority levels directly on individual interfaces is not how VRRP operates; it is inherently a group-based protocol where the configuration is done under the context of the VRRP group rather than
