单项选择题DS2 has not become the active device for Vlan103’s HSRP group even though all interfaces are active. As related to Vlan103’s HSRP group.  What can be done to make the group function properly ？ （）

A. On DS1， disable preempt
B. On DS1， decrease the priority value to a value less than 190 and greater than 150
C. On DS2， increase the priority value to a value greater 241 and less than 249
D. On DS2， increase the decrement value in the track command to a value greater than 10 and less than 50.

单项选择题During routine maintenance， G1 0 1 on DS1 was shutdown. All other interface were up. DS2 became the active HSRP device for Vlan101 as desired. However， after G1 0 1 on DS1 was reactivated. DS1 did not become the active HSRP device as desired.  What need to be done to make the group for Vlan101 function properly ？ （）

A. Enable preempt on DS1’s Vlan101 HSRP group
B. Disable preempt on DS1’s Vlan101 HSRP group
C. Decrease DS1’s priority value for Vlan101 HSRP group to a value that is less than priority value configured on DS2’s HSRP group for Vlan101
D. Decrease the decrement in the track command for DS1’s Vlan 101 HSRP group to a value less than the value in the track command for DS2’s Vlan 101 HSRP group.

单项选择题Refer to the exhibit.  Which Virtual Router Redundancy Protocol （VRRP） statement is true about the roles of the master virtual router and the backup virtual router？（）

A.Router A is the master virtual router， and Router B is the backup virtual router. When Router A fails， Router B will become the master virtual router. When Router A recovers， Router B will maintain the role of master virtual router.
B.Router A is the master virtual router， and Router B is the backup virtual router. When Router A fails， Router B will become the master virtual router. When Router A recovers， it will regain the master virtual router role.
C.Router B is the master virtual router， and Router A is the backup virtual router. When Router B fails， Router A will become the master virtual router. When Router B recovers， Router A will maintain the role of master virtual router.

单项选择题Refer to the exhibit. Switch S2 contains the default configuration. Switches S1 and S3 both have had the command spanning-tree mode rapid-pvst issued on them.  What will be the result？（）

A.Switches S1 and S3 will be able to exchange traffic but neither will be able to exchange traffic with Switch S2
B.Switches S1， S2， and S3 will be able to pass traffic between themselves. However， if there is a topology change， Switch S2 will not receive notification of the change.
C.Switches S1， S2， and S3 will be able to pass traffic between themselves.
D.IEEE 802.1D and IEEE 802.1w are incompatible. All three switches must use the same standard or no traffic will pass between any of the switches.
