1. VLSM can be used to subnet an already subnetted address.

VLSM可以被用来对已经分割子网路的位址进行子网路分割，

2. VLSM increases route summarization flexibility because it uses the higher-order bits shared on the left, even if the networks are not contiguous.

VLSM让路径加总更具弹性，因为它共享左边的更高阶位元，即使网路并不相邻。

3. In the article, the author explains the composition of the TCP/IP address class, the divide of the VLSM, the composition of the super network and the principle of the NAT.

介绍了TCP/IP协议中的地址类的构成、变长子网掩码的划分、超网的构成以及NAT转换的原理。

5. To start the VLSM process, determine the largest subnet necessary for the networks to which you assign IP addresses.

启动VLSM过程，必须为你分配IP地址的网络确定一个大的子网。

6. Figures 2 and 3 illustrate that after using VLSM, the team has eight ranges of addresses to be used for the point-to-point links.

图2及3解释了在使用VLSM之后，小组拥有8个可以用于点对点连接的位址范围。

7. The use of the first and last subnets have become an acceptable practice in conjunction with VLSM.

在VLSM内使用第一个和最后一个子网路已是大家接受的共识。

8. 29.In the implementation of VLSM techniques on a network using a single Class C IP address,which subnet mask is the most efficient for point-to-point serial links?

在使用VLSM技术的网络中使用一个C类的IP地址，以下哪个子网掩码在点对点串行链路中是最不浪费地址空间的?

9. In network that support VLSM, which network mask should be used for point-to-point WAN links in order to reduce waste of IP addresses?

在支持VLSM的网络中，为了减少地址浪费，应该在点对点的广域网链路上使用那个子网掩码？

10. On the topic of VLSM,which one of the following statements best describes the concept of the route aggression?

对于VLSM,下列哪种说法确切地描述了路由聚合的概念?

11. A routing protocol that allows VLSM gives the network administrator freedom to use different subnet masks for networks within a single autonomous system.

支援VLSM的路由协定，提供网路管理者对单一自治系统内网路，使用不同的子网路遮罩的自由。

12. When using VLSM in an EIGRP network, where can route summarization be accomplished?A.Manually on any router interface.B.Only at classless network boundaries.C.Only at classful network boundaries.

有的人认为：路由聚合一般只在网络的边缘使用,没必要在每台路由上都做.一般来说,都会把不是边缘路由器的自动归纳功能关掉.所以选C。
