Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 7

Which behavior can be expected when the HSRP version is changed from 1 to 2?

Answer options

• A. No changes occur because the standby router is upgraded before the active router.
• B. No changes occur because version 1 and 2 use the same virtual MAC OUI.
• C. Each HSRP group reinitializes because the virtual MAC address has changed.
• D. Each HSRP group reinitializes because the multicast address has changed.

Correct answer: C

Explanation

The correct answer is C because changing from HSRP version 1 to version 2 results in a new virtual MAC address format, causing all HSRP groups to reinitialize. Options A and B are incorrect as they misunderstand the implications of version changes. Option D is also incorrect because the multicast address remains consistent between versions 1 and 2.
