Which type of address is shared by routers in a HSRP implementation and used by hosts on the subnet as their default gateway address?
The correct answer is B. virtual IP address. The general idea behind HSRP is rather simple: Configure multiple devices that all exist on the same subnet and are able to act as gateways to the hosts on the subnet. Basic redundancy can be configured by configuring some of the hosts to use one gateway and the other hosts to us

Explanation
The general idea behind HSRP is rather simple: Configure multiple devices that all exist on the same subnet and are able to act as gateways to the hosts on the subnet. Basic redundancy can be configured by configuring some of the hosts to use one gateway and the other hosts to use another. However, in this situation, if either one of the gateways was to fail, then there are still a large number of hosts that would lose outside network access. HSRP provides a solution to this problem by allowing two of the connected gateways to be configured to provide redundancy. HSRP does this by providing a virtual MAC and IP address that is shared between these two devices; the active device between the two of them will be responsible for the handling of traffic to the virtual IP address, while the standby device will monitor the active device for signs of failure.
