Subnetting Only

Question 1

If a Class C address is subnetted using /27, which of the following would be the broadcast address for that subnet?

200. 14.76.254
201. 14.76.159
202. 14.76.33
203. 14.76.98
204. 14.76.87
205. 14.76.64

Answer 1

200.14.76.159

Explanation:
The Broadcast address of the class C address, which has been subnetted by / 27, is an address that is all “1”, indicating the value of the host part in binary number.
If you try all four octets of the address of the option, express them in binary numbers ….
33 → “001 00001”
64 → “010 00000”
87 → “010 10111”
98 → “011 00010”
159 → “100 11111”
254 → “111 11110”
It will be.
Because it is subnetized with / 27, the host will be 5 digits below.
Because the value of the host part is “1” is “159”, the correct answer is “200.14.76.159”

Question 2

Select the correct command for setting static NAT with the following goal:
Convert local address 172.31.1.1 to global address 200.190.10.30

(CONFIG) #IP NAT static 200.190.10.30 172.31.1.1

(CONFIG-IF) #IP NAT INSIDE SOURCE STATIC 172.31.1.1 200.190.10.30

(CONFIG) #IP NAT INSIDE SOURCE STATIC 172.31.1.1 200.190.10.30

(CONFIG) #IP NAT INSIDE STATIC 172.31.1.1 200.190.10.30

(CONFIG) #IP NAT INSIDE SOURCE STATIC 200.190.10.30 172.31.1.1

Answer 2

(CONFIG) #IP NAT INSIDE SOURCE STATIC 172.31.1.1 200.190.10.30

Explanation:
The incorrect options are as follows:
• (Config) #ip Nat Inside Source Static 200.190.10.30 172.31.1.1
The above is for the designation of the local address and the global address but in the opposite direction (global to local).

• (config) #ip NAT INSIDE STATIC 172.31.1.1 200.190.10.30
• (Config) #IP NAT static 200.190.10.30 172.31.1.1
This is incorrect, as the result of “% INVALID INPUT DETECTED AT “^” MARKER “ message will be displayed.

• (config-if) #ip Nat Inside Source Static 172.31.1.1 200.190.10.30
The mode is incorrect.
To set up static NAT Enter the command in global configuration mode.
