question on ip address
#10
Got this question on my ICND1 exam the other day.  The answer is B and D. Here is how I got my answer.

Which 2 addresses can be assigned to a host with subnet mask of 255.255.254.0? (Choose two.)

A) 113.10.4.0
B) 186.54.3.0
C) 175.33.3.255
D) 26.35.2.255
E) 17.35.36.0

Look at the 3rd Octet, 255.255.254.0

256 - 254 = 2

3rd Octet is increment by 2

Networks are
0
2
4
6 etc.. (even number)

In this example:

Subnetwork 26.35.2.0
First valid host 26.35.2.1
Last valid host 26.35.3.254
Broadcast 26.35.3.255
Next subnetwork 26.35.4.0  (remember 3rd Octet is increment by 2)

A) 113.10.4.0  (Subnetwork)
B) 186.54.3.0  (Valid host)
C) 175.33.3.255 (Broadcast)
D) 26.35.2.255  (Valid host)
E) 17.35.36.0  (Broadcast)

Answer... B and D
