You are in the process of verifying the operation of your core switches, which are using HSRP. One core switch was left with the default priority; the other was given a lower priority to make it the standby switch. The command show standby brief was executed on one of the switches. Output of the command is shown below:
What does this output mean? (Choose all that apply.)
- this switch is using the default priority
- this switch is the active HSRP switch
- the HSRP devices are up and functioning correctly
- the switch intended to be the active switch has failed and this switch has taken over
- preemption is enabled for the group
The output in the exhibit indicates that this switch is the active HSRP switch, the switch intended to be the active switch has failed, and that preemption is enabled for the group.
This is the active switch because Active is the State listed for each interface that is a member of HSRP.
The question states that the switch that was intended to be the standby switch was given a priority lower than the default. The default priority is 100, so this is not the switch intended to be the active switch. This information indicates that the switch intended to be the active switch has failed.
Preemption is enabled, as indicated by the P following the priority value in line 2. Since preemption is enabled, the switch with the priority of 100 is still down. When that switch is corrected and joins the group again, it will take over as active.
The HSRP group is still providing access for users, but not all devices are functioning properly.
