A national retail chain needs to design an IP addressing scheme to support a nationwide network.
The company needs a minimum of 300 sub-networks and a maximum of 50 host addresses per subnet.
Working with only one Class B address, which of the following subnet masks will support an appropriate addressing scheme? (Choose two.)
- A. 255.255.255.0
- B. 255.255.255.128
- C. 255.255.252.0
- D. 255.255.255.224
- E. 255.255.255.192
- F. 255.255.248.0
Answer: Option B. E.
Explanation:
50 hosts per subnet, so we’d need a range of 64 IP addresses which is a /26. This converts to a mask of 255.255.255.192.
