You administer a network that uses two routers， R1 and R2， configured as an HSRP group to 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 10.10.0.20
Which of the following describes the effect the standby preempt delay minimum 50 command will have on router R1？（）
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.
D. Router R1 will wait 50 seconds before attempting to preempt the active router.
Routers R1 and R2 are configured for HSRP as shown below：
Router R1：
interface ethernet 0
ip address 20.6.2.1 255.255.255.0
standby 35 ip 20.6.2.21
standby 35 priority 100
interface ethernet 1
ip address 20.6.1.1.2 255.255.255.0
standby 34 ip 20.6.1.21
Router R2：
interface ethernet 0
ip address 20.6.2.2 255.255.255.0
standby 35 ip 20.6.2.21
interface ethernet 1
ip address 20.6.1.1.1 255.255.255.0
standby 34 ip 20.6.1.21
standby 34 priority 100
You have configured the routers R1 & R2 with HSRP. While debugging router R2 you notice very
frequent HSRP group state transitions.
What is the most likely cause of this？ （）
A. physical layer issues
B. no spanning tree loops
C. use of non-default HSRP timers
D. failure to set the command standby 35 preempt
Exhibit

B. On R1 add the command standby 1 priority 110
C. On R1 add the command standby 1 priority 80
D. On R2 remove the command standby 1 preempt
