A. Addresses in a private range will be not routed on the Internet backbone.

B. Only the ISP router will have the capability to access the public network.

参考答案：A

第8题：

Given that you have a class B IP address network range, which of the subnet masks below will allow for 100 subnets with 500 usable host addresses per subnet?

A．255.255.0.0

B．255.255.224.0

C．255.255.254.0

D．255.255.255.0

E．255.255.255.224

正确答案：C
解析：Explanation:
Using the 2n-2 formula for host addresses, 29-2 = 510 host address, so a 9-bit subnet mask will provide the required number of host addresses. If these 9 bits are used for the hosts in a class B network, then the remaining 7 bits are used for the number of networks.

Again using the 2n-2 formula, we have 2n-2 = 126 networks that are available.

Incorrect Answers:
A. This will provide for only 1 network with 216-2 = 65534 hosts
B. This will provide for 6 networks with 8190 host addresses.
D. This will provide 254 networks and 254 hosts.
E. This will provide 2046 different networks, but each network will have only 30 hosts.
