Which NAT configuration translates source subnet 10.10.0.0/24 to any of 192.168.3.1–192.168.3.3?

The correct configuration uses ip nat inside source list 1 pool mypool to translate source addresses matching access-list 1 (10.10.0.0/24) to an address from the mypool range (192.168.3.1-192.168.3.3). This is standard dynamic NAT. The prefix-length 30 in the pool definition correctly defines the subnet mask for the NAT pool addresses. The access-list 1 permit 10.10.0.0 0.0.0.255 correctly identifies the source subnet. Finally, interface g1/1 ip nat inside and interface g1/2 ip nat outside correctly designate the inside and outside interfaces for NAT. The first incorrect option uses ip nat outside destination list 1 pool mypool, which is for destination NAT, not source NAT. The second incorrect option has an incorrect wildcard mask 0.0.0.254 for the access-list, which would not match the entire /24 subnet. The third incorrect option attempts to use a route map instead of an access-list for identifying the source addresses, and also incorrectly uses ip nat outside destination.
