Ferris Plastics, Inc. is a medium sized company, with an enterprise network (access, distribution and core switches) that provides LAN connectivity from user PCs
to corporate servers. The distribution switches are configured to use HSRP to provide a high availability solution.
· DSW1 primary device for VLAN 101 VLAN 102 and VLAN 105
· DSW2 primary device for VLAN 103 and VLAN 104
/
· A failure of GigabitEthemet1/0/1 on primary device should cause the primary device to release its status as the primary device, unless GigabitEthernet1/0/1 on
backup device has also failed.
Troubleshooting has identified several issues. Currently all interfaces are up. Using the running configurations and show commands, you have been asked to
investigate and respond to the following question.
During routine maintenance, it became necessary to shut down the GigabitEthernet1/0/1 interface on DSW1 and DSW2. All other interfaces were up. During this
time, DSW1 became the active router for the VLAN 104HSRP group. As related to the VLAN 104HSRP group, what can to be done to make the group function
properly?
A.
On DSW1, disable preempt.
B.
On DSW2 decrease the priority value to a value less than 150.
C.
On DSW1, increase the decrement value in the track command to a value greater than 6.
D.
On DSW1, decrease the decrement value in the track command to a value less than 1.
Explanation:
We should NOT disable preempt on DS1. By do that, you will make Vlan104’s HSRP group fail function. Example: if we are disable preempt on DS1. It can not
become active device when G1/0/1 on DS2 fail. In this question, G0/1/0 on DS1 & DS2 is shutdown. Vlan104 (left): 150 1 = 149. Vlan104 (right): 200 155 = 145.
Result is priority 149 > 145 (Vlan104 on DS1 is active). If increase the decrement in the track value to a value greater than 6 (> or = 6). Vlan104 (left): 1506 = 144. Result is priority 144 < 145 (vlan104 on DS2 is active).
