Configure the D-SW2 switch as the standby HSRP router and the backup STP root for VLANs 11 and 110. Answer: CF Explanation:
Basically, each of the routers that provides redundancy for a given gateway address is assigned to a common HSRP group. One router is elected as the primary, or active, HSRP router, another is elected as the standby HSRP router, and all the others remain in the listen HSRP state. The routers exchange HSRP hello messages at regular intervals, so they can remain aware of each
