Refer to the exhibit:
Which command would allow the translations to be created on the router?
A.
ip nat pool mynats 1.1.128.1 1.1.135.254 prefix-length 19
B.
ip nat outside mynats 1.1.128.1 1.1.135.254 prefix-length 19
C.
ip nat pool mynats 1.1.128.1 1.1.135.254 prefix-length 18
D.
ip nat outside mynats 1.1.128.1 1.1.135.254 prefix-length 18
A. ip nat pool mynats 1.1.128.1 1.1.135.254 prefix-length 19
–is true because, to add a new nat pool y the right command
–1.1.128.1 1.1.135.254 prefix-length 19 cover the subnet needed
prefix-length 19 mean: /19—->0.0.32.0 increments
The right answer is A.
We have 1.1.128.1 to 1.1.135.174 range of IP addresses.
Prefix-lenght 19 it is 255.255.240.0 subnet mask.
So mask /19 fully cover our needs.
0.0.16.0 – 0.0.31.255
0.0.32.0 – 0.0.63.255
0.0.64.0 – 0.0.79.255
0.0.80.0 – 0.0.95.255
0.0.96.0 – 0.0.111.255
0.0.112.0 – 0.0.127.255
0.0.128.0 – 0.0.143.255
also /18 is fulfill our needs 🙁
Dima,
You may want to check your mask. /19 = 255.255.224.0
Giving us a range of 128.1 to 159.254.
