(70-67)NT
Server 4.0 一道著名考题的分析
(70-67)NT Server 4.0考试有一道著名(老外称之为infamous，有贬义)的关于
Roaming Mandatory User Profile的考题，从以前的传统型考题到如今的自适
应考题几乎每次考试都会出现，到底答案如何莫衷一是，Branidump上争得也
是一塌糊涂，答错了以为自己是对的，答对了也不知道为什么对。今天我们
就来解决这个MCSE征途上的拦路虎。
题目：
Your network is configured as a single domain that has 3 domain controllers
and 25 Windows NT Workstation computers. For security purposes, you assign
roaming user profiles to all user accounts in the domain. The profiles are
mandatory. The server on which the profile resided is down. what happen when
users logon?
a) Users will log on successfully and will receive the default user profile.
b) Users will log on successfully and will receive their profiles, but any
changes made to the computer will be lost.
c) Users will log on successfully and receive a cached mandatory profile.
d) Users will not be able to log on to the domain.
正确答案到底是什么呢?
请看微软对“How to create roaming mandatory profiles”的权威解释：
(如果你是第一次用MS的在线Knowledge Base,需在使用前填一简单表格)
http://support.microsoft.com/support/kb/articles/q168/4/76.asp?FR=3D0
显然，针对Roaming Mandatory Profile的两层security level，答案a和答案
d都是 可能的正确答案.(注：答案c是错误的,因为mandatory profile不会被
cached,如c改为 cached user profile,则在Roaming Mandatory Profile的两
种security level第一层 security level的情况下，如the server on which
the mandatory profile resided is down,那么用户登录首先receive cached
user profile,如没有，再receive default user profile.而且，如果严格按
照微软文中推荐的方法创建roaming mandatory profile, 则本题目的情况
下，用户本地只有default user profile,而没有cached user profile.)
那么正确答案到底是a还是d呢？EasyMCSE Cram Bible for 70-67 Windows NT
Server 4.0 中的答案原来是a,而且微软MCP/MCSE考试以前也是以a为正确答案
但从最近的考生反馈来看，
微软更改了标准答案。可能出题者认为要正确创建
roaming mandatory profiles，就必须 按knowledge base的文章所述建立两
层security level.令人奇怪的是，在微软的培训教材 (MOC)和其它相关考试
辅导教材中都找不到关于roaming mandatory profile第二层security level
的描述。
这到臭名昭著(infamous)的考题的问题就是题目本身模棱两可。但无论如何，
如果你参加 考试，那么答案永远是"user can NOT log on".

Another
infamous MCSE test question (70-87 IIS4)
You have a high number of not found errors on your web site. Why?
(choose 2)
A. Wrong virtual directory configuration
B. Wrong permission for anonymous account
C. Excessive traffic on network segment
D. Error on HTML codes on pages
Answer: A, D
Explanation:
The question means what will cause "404 File Not Found" error.
A is absolutely right.
B is wrong. This will cause "403 Forbidden" error.
C is wrong. This will only cause "Time out" and other errors.
Because of the excessive network traffic, sometime your browser
even can't have a normal HTTP connect with the IIS4.0 web server.
D is right. OK, only right in part if you have an error with the
HTML file link.
This is really a poorly worded question. If you are asked to choose
only ONE correct answer, surely A is right. If unlucky you are asked
to choose TWO correct answer, I personally think that you should
choose A&D. You can also find this question from our EasyMCSE Cram
Bible for 70-87 IIS4.0 and we only provide you with the correct
answer A.
Any comments are welcome.

(70-058)Networking
Essentials中关于NetBIOS名称解析的两道题
Q1. You want to manage Microsoft Windows NT server computers that are
located on remote subnet. All of these servers are configured in a
single Windows NT domain. You will manage these servers from another
Windows NT server computer that is located in your office. You want
to use User Manager and Server Manager to manage the remote servers.
What should you install and configure to resolve the computer names
of the servers? (Choose 2).
a. DNS
b. WINS
c. RPC
d. DHCP
e. LMHOSTS
分析: MCSE考题常常是题目很长,废话多,迷惑你的话也多,诀窍是把最后的问题
吃透. "What should you install and configure to resolve the computer
names of the servers?", 原来是问computer names的解析,即网络中NetBIOS
名称的解析. 我们知道在Microsoft Network中NetBIOS名称的解析是按如下机理
和顺序: 本地Cache --> WINS --> Broadcast --> LMHOSTS file --> HOSTS file
--> DNS. 其中, WINS和LMHOSTS file的解析方法是Mircosoft Network的特色.
DNS解析的引入主要是为了和Internet兼容. 因此,两个最佳答案应为: b和e.
Q2. You manage 4 NT servers directly connected to the Internet. All 4
are configured in a single NT domain. You manage the 4 servers from
another NT server located in your office. The server in your office
connects to the Internet using dial-up connection. You want to use
Server Manager and User Manager to manage the 4 servers. What should
you install and configure to resolve the computer names of the servers?
a. DNS server on Internet.
b. WINS server in your office with only dynamic mapping.
c. DHCP server on the Internet.
d. LMHosts file on the server in your office.
分析: 考试的时候还要注意要仔细看题目. 如本题,问题的实质和上一题一样,都
是问NetBIOS名称的解析,但问题情景发生了变化 -- 引入了Internet连接.显然,
答案c和问题无关,排除. 那么a,b,d中的DNS,WINS,LMHosts file都能解析NetBIOS
名称,到底哪个对呢? 题目中提到 4 NT Servers directly
connected to the
Internet,其中directly connected to the Internet的意思即指这4台NT Server
的IP地址是静态或固定的. 因此,答案b.WINS server in your office with only
dynamic mapping不能满足题目的要求. 另外, DNS主要是用来解析HOSTS名称,而
且为了解析4台固定IP地址的计算机LMHOSTS file比用DNS来得方便简洁的多.
因
此,本题的正确答案应为d.
最近,微软又改变了(70-058)Networking Essentials的考试形式,(请参看"考试快讯")
添了一些新题,对NetBIOS名称的解析提出了更高的要求.希望对以上两道考题的分
析能对您有所帮助.

1) EasyMCSE Cram Bible for (70-058)Networking Essentials已升级到最新的
3.0版,请到"升级指南"获得详细信息.
2) 您可以在"用户回应"参看EasyMCSE Cram Bible for 70-058用户考试后的反馈.
