Which command enables subnet 192.168.8.4/30 to communicate with subnet 192.168.8.32/27 on
IP protocol 50?

A.
permit esp 192.168.8.4 255.255.255.252 192.168.8.32 255.255.255.224

B.
permit esp 192.168.8.4 0.0.0.31 192.168.8.32 0.0.0.31

C.
permit esp 192.168.8.4 255.255.255.252 224.168.8.32 255.255.255.192

D.
permit esp 192.168.8.4 0.0.0.3 192.168.8.32 0.0.0.31

Explanation:
Access lists use inverse wildcard masks, so a /30 subnet translates to 0.0.0.3, where as a
standard wildcard mask used in static routes would be 255.255.255.252. Similarly, a /27 would be
.0.0.0.31, which is the opposite of a /27 255.255.255.224 used in static routes.
