priority-value global configuration command must be used.
B. The default priority of a router is zero (0).
C. The no standby priority command assigns a priority of 100 to the router.
D. Assuming that preempting has also been configured, the router with the lowest priority in an HSRP
group would become the active router.
E. When two routers in an HSRP standby group are configured with identical priorities, the router with
the highest configured IP address will become the active router.

B. Only if the state of both tracked objects goes down will this router release its status as an AVF
for group 1.
C. If both tracked objects go down and then one comes up, but the other remains down, this router
will be available as an AVF for group 1.
D. This configuration is incorrect and will not have any effect on GLBP operation.
E. If the state of one tracked object goes down then this router will release its status as an AVF for
