A.8 第8章答案
1) C。A p p l e Ta l k地址是2 4位的。它包括一个1 6位的网络号和一个8位的节点号。
2) A。A p p l e Ta l k地址的两部分分别是1 6位的网络号和8位的节点号。
3) D 。L o c a l Ta l k在几乎所有的M a i n t o s h型号上都是标准的。A p p l e Ta l k打印机也有一个L o c a l Ta l k接口。
4) A。A p p l e Ta l k地址的节点部分是8位。地址的网络部分是1 6位。总计它们组成了2 4位的
A p p l e Ta l k地址。
5) B。特定的组或部门使用的网络资源组到一个区域中。通过A p p l e Ta l k区域的概念来产生功能分组。工作组和虚拟L A N是常用术语，不是A p p l e Ta l k结构。电缆范围用来向网络链路分配网络号围。
6) B。A p p l e Ta l k使用数据报发送协议向上层协议提供无连接数据报传送服务。
7) D。可以向一个接口分配多个区域。Z I P和RT M P都是协议。两个电缆范围不可以分配到一个接口中。电缆范围分配必须是唯一的。
8) B。A p p l e Talk CABLE-RANGE命令分配在给定网络接口上使用的网络号范围。Z O N EN A M E命令(答案A )为接口分配区域。答案C是关闭，但是它没有电缆和范围之间的连字符。
9) E。I G R P仅仅处理I P通信量。所有其他路由选择协议可以用来帮助维护A p p l e Ta l k路由选择表。
10) A。RT M P每隔1 0秒向它的邻居广播它的路由选择表。
11) A。A P P L E TALK PROTOCOL RT M P在基本A p p l e Ta l k配置中不是必要的。只要已经正确地分配了电缆范围和区域名， RT M P就在接口上自动启动。
12) D 。A p p l e Ta l k过滤用到的访问列表号是6 0 0 ~ 6 9 9。
13) D。命令SHOW APPLETALK ROUTE显示了所有已知的电缆范围和路程段计数，它们是到达电缆范围识别的每个网络所需要的。
14) D。客户使用G E T Z O N E L I S T命令从路由器获得区域列表。路由器通过Z I P而不是基于G E T Z O N E L I S T命令的AT P来交换区域信息。z i p - r e p l y - f i l t e r是路由器间过滤Z I P的机制，因此答案D最佳。
15) C。既然客户使用G E T Z O N E L I S T命令从路由器获得区域列表， 那么使用G E T Z O N E L I S T- F I LT E R过滤该列表将禁止客户M了解S e r i a l Z o n e的存在。Z I P - R E P LY FILT E R
仅仅过滤Z I P。G E T Z O N E L I S T命令通过AT P来执行，所以使用Z I P - R E P LY FILT E R是无效的。
16) B 。命令A P P L E TALK ZONE用来向接口分配区域名。语法是A P P L E TALK ZONEM Y Z O N E。它是一个接口级的命令。
17) B 。A P P L E TALK DISCOVERY激活C i s c o路由器中的自动发现进程。
18) B。这些命令都是接口配置命令。答案A错在A P P L E TALK ROUTING是一个全局配置命令。答案C和D错在A P P L E TALK ACCESS-LIST根本不是一个命令。
19) A。A P P L E TALK CABLE RANGE命令将电缆范围分配到接口，但是它也导致了自动分配节点地址的发生。节点分配的结果可以使用SHOW RUN命令来查看，该命令会显示A P P L E TALK CABLE-RANGE命令及随后的自动分配的节点号。其他所列的命令都是非法的。
20) D 。A P P L E TALK ROUTING 是一个全局配置命令，需要它引起路由器来路由A p p l e Ta l k数据包。如果没有A P P L E TALK ROUTING命令，路由器会桥接A p p l e Ta l k通信量，下载
(如果正确配置的话)但是路由选择不发生。
21) A-4，B - 3，C - 1，D - 2。
22) B 。F D D I Ta l k支持1 0 0 M b p s。To k e n Ta l k支持4 M b p s或者1 6 M b p s。L o c o l Ta l k支持 2 3 0 K b p s。
23) C 。N B P是传输层协议。
24) D。通过在指定的区域中允许直接向设备请求，使得分区域的方法减少了开销。分区的目的是防止请求向整个网络传播。
25) B 。RT M P用来维护路由选择表，它使用一个距离向量路由选择协议来完成该任务。
26) C 。N B P的主要功能之一是将名字映射到地址以向应用程序提供该服务。
27) A 。A D S P是用来进行应用程序间进行数据交换的首选协议。
28) B 。错误。M A C地址没有随位置的改变而改变。网络地址在不同的位置是可以不同的。
29) D。路由器分配网络号。网络号标识和客户设备关联的网段。
30) D。扩展的A p p l e Ta l k寻址允许向一个网段分配多个网络号。因此，在该编地规划中，
最多可以有65 535个网络和一个网段相关。在非扩展的编地规划中，仅仅向网络分配网络I D和一个区域名。
31) E 。严格地讲，答案是B，即电缆范围和网段相关。然而，路由器接口用来向适当的网络路由通信量。因此，答案C也是正确的。
32) C。所有的A p p l e Ta l k网络号必须小于65 536。网络地址是1 6位的。这意味着有65 536
的限制。
33) A 。2 5 5用作广播节点号。
34) D。对于4 5 0 ~ 4 5 4的电缆范围，最大主机号是1 2 7 0。主机号等于网络号的倍数： 2 5 4 . 5
×2 5 4 = 1 2 7 0。
35) D。电缆范围和A p p l e Talk CABLE-RANGE命令一起分配；它们是向一个网段分配的网络号；它们不能和先前分配的电缆范围有重叠。
36) B 。在这些选项中， 6 3 0 1 ~ 6 4 0 0是网段Y可接受的唯一电缆范围。答案A和C是和2 0 0 ~ 3 0 0重叠的，因此它不能使用。
37) A。正确。节点可选取范围内的任意网络号。
38) C。SHOW APPLETALK INTERFA C E说明了接口的状态并且显示了是否接口配置有效。
39) B 。0 - 0电缆范围用来显示用于I O S的A D。
40) B。要使A p p l e Ta l k发现正常工作，在A p p l e Ta l k发现应用到非种子路由器中之前，种
子路由器必须在适当的位置并运行。
41) C 。三个必要的命令分别是： A P P L E TALK ROUTING、A P P L E TALK CABLE和R A N G E H和A P P L E TALK INTERFA C E。
42) A 。A C C E S S - G R O U P命令和A C C E S S - L I S T命令都是激活接口上访问列表所需要的。
43) A。对于早于11 . 3的I O S版本，默认是出站的。11 . 3版本的I O S支持入站指令。
44) C 。用来监视A p p l e Ta l k配置的命令是SHOW APPLETALK INTERFA C E，S H O W A P P L E TALK INTERFA C E和SHOW APPLETALK ZONE。
45) C 。R表示电缆范围3 0 0 ~ 3 9 9通过RT M P可知。
46) B。1 0秒是包括电缆范围3 0 0 ~ 3 9 9的条目最新RT M P更新之后所过去的时间。当RT M P正在正常运行时，该数字应该不大于1 0秒，这是因为RT M P更新间隔是1 0秒。
47) C 。4 0 0 . 9 7是通告电缆范围的路由器的A p p l e Ta l k地址。
