provide redundancy for the gateway. Router R1 is the active router and has been configured as follows:
R1#configure terminal R1(config)#interface fa0/0 R1(config-if)#ip address 10.10.0.5 255.255.255.0 R1(config-if)#standby 1 priority 150 R1(config-if)#standby preempt delay minimum 50 R1(config-if)#standby 1 track interface fa0/2 15 R1(config-if)#standby 1 ip 10.10.0.20Which of the following describes the effect the standby preempt delay minimum 50 command will have on router R1? (Select the best answer.)
- A.The HSRP priority for router R1 will increase to 200.
- B.Router R1 will become the standby router if the priority drops below 50.
- C.The HSRP priority for router R1 will decrease to 50 points when Fa0/2 goes down.
