Correct answer: HSRPv1 uses a group range of 0–255, while HSRPv2 uses a group range of 0–4095., HSRPv1 uses seconds-based timers, while HSRPv2 uses millisecond-based timers..
Why this is the answer
HSRPv2 offers several enhancements over HSRPv1. One key difference is the expanded group range: HSRPv1 supports groups 0-255, while HSRPv2 extends this to 0-4095, allowing for more HSRP groups on a single interface. Another significant improvement in HSRPv2 is the support for millisecond-based timers, enabling faster failover detection and convergence compared to HSRPv1's seconds-based timers. Regarding the incorrect options: HSRPv1 uses the multicast address 224.0.0.2, not 224.0.0.102 (which is used by HSRPv2). Also, HSRPv2 supports both IPv4 and IPv6, while HSRPv1 is limited to IPv4.
