All computers on your network use the 10.10.0.0/16 address scheme. Tom, your manager, instructs you to place the 15 servers into a separate subnet that uses the 192.168.10 public addressing scheme. You must plan for a maximum of 25 servers in the future and need to configure a new subnet mask.
The subnet mask must allow a sufficient number of IP addresses for the existing servers and future growth. However, you want to conserve addresses as much as possible. Which subnet mask should you use?
A)255.255.255.248
B)255.255.255.240
C)255.255.255.224
D)255.255.255.252

You should use the 255.255.255.224 subnet mask to conserve as many addresses as possible. Key Takeaway: The 255.255.255.224 subnet mask gives five host address bits. The maximum number of host addresses available is 2⁵- 2 = 30 host addresses. This subnet mask will allow for sufficient IP addresses in case of further growth, while conserving as many current addresses as possible.
