Cisco CCNA mock exam questions sample test – Question 254

.The partial output displayed in the exhibit is a result of what IOS command? (Click on the Exhibit(s) button.)

A. switch# show running-config
B. switch# show standby vlan1 active brief
C. switch# show hsrp 1
D. switch# show standby


Correct Answer: D

Explanation:
The command shows standby produces the output displayed in the exhibit. This command displays information about HSRP on all configured interfaces and for all HSRP groups.
Important information in the exhibit includes that this router is the active router, the virtual IP address for the HSRP group is 172.16.1.20, the address of the standby router is
172.16.1.6, and the router is configured to preempt.
The command show running-config will display the complete configuration of the device, including the configuration of HSRP, but will not display the current status of HSRP on the
switch.
The command show standby vlan 1 active brief provides a summary display of all HSRP groups on the switch that are in the active state. This output would provide basic information,
not nearly the detail indicated in the exhibit. The following is an example of output for show standby vlan 1 active brief:
Interface Grp Prio P State Active addr Standby addr Group addr
Vlan1 0 120 Active 172.16.1.5 Unknown 172.16.1.20
The command show hsrp 1 is not valid due to incorrect syntax.
Objective:
Infrastructure Services
Sub-Objective:
