Which command will create a dynamic pool named Todd that will provide you with 30 global addresses?
ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.240
ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224
ip nat pool todd 171.16.10.65 171.16.10.94 net 255.255.255.224
ip nat pool Todd 171.16.10.1 171.16.10.254 net 255.255.255.0
Answer: Option
Explanation:
The command ip nat pool <name> creates the pool that hosts can use to get onto the global Internet. What makes option B correct is that the range 171.16.10.65 through 171.16.10.94 includes 30 hosts, but the mask has to match 30 hosts as well, and that mask is 255.255.255.224. Option C is wrong because the pool name has a lower case "T" in the pool name. Pool name's are case sensitive.
