A network administrator would like to ensure that router R1 is always elected the active router for an HSRP group. Which set of commands would ensure the required results?
R1(config-if)# ip address 192.168.1.100 255.255.255.0
R1(config-if)# standby 1 ip 192.168.1.1
R1(config-if)# standby 1 priority 150
R1(config-if)# no shutdown
R1(config-if)# ip address 192.168.1.250 255.255.255.0
R1(config-if)# standby 1 ip 192.168.1.1
R1(config-if)# no shutdown
R1(config-if)# ip address 192.168.1.100 255.255.255.0
R1(config-if)# standby 1 ip 192.168.1.1
R1(config-if)# standby 1 priority 1
R1(config-if)# no shutdown
R1(config-if)# ip address 192.168.1.100 255.255.255.0
R1(config-if)# standby 1 ip 192.168.1.1
R1(config-if)# standby 1 priority 255
R1(config-if)# standby 1 preempt
R1(config-if)# no shutdown
Explanation: In order to configure HSRP, the standby command is used. The IP address given with the standby command is the virtual IP address used by hosts as a default gateway. A priority number of 255 is the highest that can be assigned and should be configured on the router that is to be the active router.
