| Question 27 |
An organization has a class B network and wishes to form subnets for 64 departments. The subnet mask would be:
| 255.255.0.0 | |
| 255.255.64.0 | |
| 255.255.128.0 | |
| 255.255.252.0 |
Question 27 Explanation:
Organization have 64 departments, and to assign 64 subnet we need 6 bits for subnet. In Class B network first two octet are reserved for NID, so we take first 6 bit of third octet for subnets and subnet mask would be 255.255.11111100.00000000 = 255.255.252.0
