- 2. Which command will create a dynamic pool named Todd that will provide you with 30 global addresses?
Options- A. ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.240
- B. ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224
- C. ip nat pool todd 171.16.10.65 171.16.10.94 net 255.255.255.224
- D. ip nat pool Todd 171.16.10.1 171.16.10.254 net 255.255.255.0 Discuss
Correct Answer: ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224
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 there is a lowercase t in the pool name. Pool name are case sensitive.

Options- A. debug ip nat
