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.

Explanation:
# v4 |/ c) M+ j) V+ Access – The access template maximizes system resources for access control lists (ACLs) to accommodate a large number of ACLs.
7 D/ V" z5 O& B/ c* e+ Default – The default template gives balance to all functions.
8 ]9 M+ u8 o0 {1 r+ Routing – The routing template maximizes system resources for IPv4 unicast routing, typically required for a router or aggregator in the center of a network.& @9 S7 P# p9 g. d
+ 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.% b/ Q, E; J) i6 t# m9 I
