350-401 · Question #884
What are some of the key differences between HSRPv1 and HSRPv2? (Choose two.)
The correct answer is B. HSRPv1 uses a group range of 0-255, while HSRPv2 uses a group range of 0-4095. C. HSRPv1 uses seconds based timers, while HSRPv2 uses milliseconds based timers.. HSRPv2 offers significant improvements over HSRPv1, including an expanded group range and support for millisecond-based timers, enabling more flexible and faster failover deployments.

Why each option
HSRPv2 offers significant improvements over HSRPv1, including an expanded group range and support for millisecond-based timers, enabling more flexible and faster failover deployments.
HSRPv1 uses the multicast address 224.0.0.102, and HSRPv2 uses 224.0.0.102 for IPv4 and FF02::66 for IPv6, not 225.0.0.2.
HSRPv1 supports a group range of 0-255, which can be limiting, whereas HSRPv2 expands this range to 0-4095, providing more available groups for redundancy configurations. This larger range allows for more granular and scalable deployments of HSRP on network interfaces.
HSRPv1 uses second-based timers for hello and hold times, leading to slower convergence during a failover event. HSRPv2 introduces the capability for millisecond-based timers, allowing for much faster detection of master router failures and quicker failover to a standby device.
HSRPv1 supports IPv4 only, while HSRPv2 extends support to both IPv4 and IPv6, contrary to the statement.
