Explanation:
5 \8 W& K5 J0 v+ L; R5 ZYou can eliminate configurations with the word ‘standby’, as that would be HSRP, not VRRP. Also, I think the options that put things like vrrp group 1 ip x.x.x.x are wrong. You don’t need the word ‘group’ in the configuration line. The number 1 is the group number. Anyway, just take a good look a t a few valid VRRP configuration examples so that you will be able to recognize invalid ones.
