Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 396

What are some of the key differences between HSRPv1 and HSRPv2? (Choose two.)

Answer options

• A. HSRPv1 uses the multicast address of 224.0.0.102 while HSRPv2 uses 225.0.0.2.
• B. HSRP uses a group range of 0-255, while HSRP uses a group range of 0-4095.
• C. HSRPv1 uses seconds based timers, while HSRPv2 uses milliseconds based timers.
• D. HSRPv1 provides support for IPv6, while HSRPv2 supports IPv4 only.

Correct answer: B, C

Explanation

The correct answers are B and C because HSRPv1 indeed has a group range of 0-255, while HSRPv2 extends this range to 0-4095, and HSRPv1 uses second-based timers compared to millisecond-based timers in HSRPv2. Options A and D are incorrect as HSRPv1 does not support IPv6, and both versions use the same multicast address of 224.0.0.102.
