第3题：

The 201.145.32.0 network is subnetted using a /26 mask. How many networks and IP hosts per network exists using this subnet mask?

A．4 networks and 64 hosts

B．64 networks and 4 hosts

C．4 networks and 62 hosts

D．62 networks and 2 hosts

E．6 network and 30 hosts


正确答案：C
解析：Explanation:
A class C network with a 26 bit mask requires 2 bits for the network address, leaving 6 bits for host addresses. Using the 2n-2 formula (22 for the network and 26-2for hosts) we have 4 network addresses and 62 host addresses.

Incorrect Answers:
A, B: This is not a possible combination. No network mask will provide for 64 usable hosts, because we must always subtract 2 for the network and broadcast address.
D. This would be the result of a /30 mask.
E. This would be the result of a /27 network mask.

第8题：

You need subnet a Ezonexam network segment. How many subnetworks and hosts are available per subnet if you apply a /28 mask to the 210.10.2.0 class C network?

A. 30 networks and 6 hosts.

B. 6 networks and 30 hosts.

C. 8 networks and 32 hosts.

D. 32 networks and 18 hosts.

E. 16 networks and 14 hosts.

F. None of the above


正确答案：E
E 解析：Explanation:
A 28 bit subnet mask (11111111.11111111.11111111.11110000) applied to a class C network uses a 4 bits for networks, and leaves 4 bits for hosts. Using the 2n-2 formula, we have 24-2 (or 2x2x2x2-2) which gives us 14 for the number of hosts, and the number of networks is 24 = 16.

Incorrect Answers:
A. This would be the result of a /29 (255.255.255.248) network.

B. This would be the result of a /27 (255.255.255.224) network.

C. This is not possible, as we must subtract two from the subnets and hosts for the network and broadcast addresses.

D. This is not a possible combination of networks and hosts.
