ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.240

ip nat pool Todd 171.16.10.1 171.16.10.254 net 255.255.255.0

ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224

Answer 1

To create a dynamic NAT pool with 30 global addresses, you need to calculate the appropriate subnet mask that will provide at least 30 usable addresses.

A typical subnet that provides at least 30 usable addresses is a /27 subnet, which has a subnet mask of 255.255.255.224. This subnet allows for 32 IP addresses in total, of which 30 are usable (the first address is the network address and the last is the broadcast address).

Looking at the provided options, the command that creates a pool of 30 global addresses is:

**`ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224`**

Here’s the breakdown:
- The starting address is **171.16.10.65**.
- The ending address is **171.16.10.94** (which provides a total of 30 addresses from .65 to .94).
- The netmask **255.255.255.224** corresponds to a range that allows for 30 usable addresses.

Therefore, the correct command is:

**`ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224`**.
