What command would display a single line of information for each virtual gateway or virtual forwarder on a switch?
A. switch# show glbp
B. switch# show glbp brief
C. switch# show standby
D. switch# show standby brief
Correct Answer: B
Explanation/Reference:
Answer:
A brief single line view of virtual forwarder and virtual gateway information is provided with the command show glbp brief. Virtual forwarders and virtual gateways are terms used for GLBP groups. A brief output of GLBP information is provided with the brief key word. This output includes the interface, priority, state, and address of GLBP interfaces on the switch.
The command show glbp displays detailed information about GLBP groups on the switch. This information includes the GLBP groups the switch is a member of, whether this is the active switch, the virtual IP address, and whether preemption is enabled.
The command show standby brief is used to display a summary of the HSRP groups to which the switch belongs. The summary information it provides includes the group number, priority, state, active device address, standby address, and group address. This command is for HSRP only.
The command show standby can be used to display detailed information about HSRP groups to which a switch belongs. This command is for HSRP only.

Wrong – The correct answer is A. First the output shows “load balancing’ data, meaning is GLBP. Second the “show glbp brief” command is shown in a table style while the “show glbp” is more vertical output data.
