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:
5 w, Z5 h0 h- ?. e+ Access – The access template maximizes system resources for access control lists (ACLs) to accommodate a large number of ACLs.; Y _& k( F; D2 J R6 {
+ Default – The default template gives balance to all functions.# i, Z; r) Q9 e* V; |. y/ y) V
+ Routing – The routing template maximizes system resources for IPv4 unicast routing, typically required for a router or aggregator in the center of a network.
4 M4 t! }4 p1 T, P: s+ 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.- g# C. ]$ a0 }& E( o, }7 [
