Question:
Which command can you enter to create a NAT pool of 6 addresses?

• Router(config)#ip nat pool test 175.17.12.69 175.17.12.74 prefix-length 24
• Router(config)#ip nat pool test 175.17.12.69 175.17.13.74 prefix-length 16
• Router(config)#ip nat pool test 175.17.12.66 175.17.12.72 prefix-length 8
• Router(config)#ip nat pool test 175.17.12.69 175.17.12.76 prefix-length 8

Explanation: The syntax to create a NAT pool is:

Router(config)#ip nat pool pool_name start_ip end_ip { netmask netmask | prefix-length prefix-length }

Therefore answer A is surely correct. Answer B is not correct as it creates many addresses (from 12.69 to 12.255 then to 13.74).

Answer C and D are not correct as we cannot use prefix-length of 8 (/8) for a class B subnet.
