What is the subnetwork address for a host with the IP address 200.10.5.68/28?
200.10.5.56
200.10.5.32
200.10.5.64
200.10.5.0
Answer: Option
Explanation:
This is a pretty simple question. A /28 is 255.255.255.240, which means that our block size is 16 in the fourth octet. 0, 16, 32, 48, 64, 80, etc. The host is in the 64 subnet.

A senior admin at your network has subnetted the 178.14.0.0 network with a /21 mask and has naturally handed it over to you at this point. How many subnets does this leave you to work with?

Can anyone help me by explaining this?

/28 means 11111111.11111111.11111111.11110000.

Means there are 4 ON's i.e 1's 2^4 = 16 block size.

So address will be:

200.10.5.0.
200.10.5.16.
200.10.5.32.
200.10.5.48.
200.10.5.64--------200.10.5.79.
200.10.5.80.

Means 200.10.5.68 lies b/w 200.10.5.64.

So answer is (C).
