You 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.; Z0 G7 Z$ G0 X( M

+ VLANs – The VLAN template disables routing and supports the maximum number of unicast MAC addresses. It would typically be selected for a Layer 2 switch.5 B) u* ?* v, J M
