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
Which command will ensure that Company2 will be the primary router for traffic using the gateway address of 172.16.15.20？ （）
A. On R2 add the command standby 1 priority 80
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
Refer to the exhibit. What statement is true based upon the configuration of router R1 and router R2？（）
A. Router R2 will become the master for Virtual Router 1， and router R1 will become the backup for Virtual Router 2.
B. Router R1 will become the master for Virtual Router 1， and router R2 will become the backup for Virtual Router 2.
C. Router R1 will become the active virtual gateway.
D. Router R2 will become the active virtual gateway.
E. The hello and hold timers are incompatible with OSPF type 5 LSAs.
F. The hello and hold timers are incompatible with multi-homed BGP.
.Refer to the exhibit and the partial configuration on routers R1 and R2. Hot Standby Routing Protocol （HSRP） is configured on the network to provide network redundancy for the IP traffic. The network administrator noticed that R2 does not become active when the R1 serial0 interface goes down.
What should be changed in the configuration to fix the problem？ （）
A. The Serial0 interface on router R2 should be configured with a decrement value of 20.
B. The Serial0 interface on router R1 should be configured with a decrement value of 20.
C. R2 should be configured with a standby priority of 100.
D. R2 should be configured with a HSRP virtual address.
Refer to the exhibit. Based on the debug standby output in the exhibit， which HSRP statement is true？ （）
A. DSW111 is the active router because it is the only HRSP-enabled router on that segment.
B. DSW111 is the active router because the standby timer has been incorrectly configured.
C. DSW111 is the active router because it has a lower priority on that VLAN.
D. DSW111 is the active router because it has a lower IP address than the tying priority router on that VLAN.
E. DSW111 is the active router and is advertising the virtual IP address 10.10.10.111 on VLAN 11.
Refer to the exhibit. Based on the debug standby output in the exhibit，
which HSRP statement is true？（）
A. DSW111 is the active router because it is the only HRSP-enabled router on that segment.
B. DSW111 is the active router because the standby timer has been incorrectly configured.
C. DSW111 is the active router because it has a lower priority on that VLAN.
D. DSW111 is the active router because it has a lower IP address than the tying priority router on that VLAN.
E. DSW111 is the active router and is advertising the virtual IP address 10.10.10.111 on VLAN 11.
