Subject: TCP/IP (70-059) Brain dump
I read Sybex book, It is nice to use for fundamental knowledge but, the thing that really helped me is this braindump and Transendent test. If you have covered the course material,and also used transendent, I think you can never fail.
Some observations..........
There were three questions based on the same scenario only the proposed solutions were changed and you have to answer the Questions by selecting the best option.
Network with 100 workstations and 20 UNIX computers. UNIX computers never move,each Unix-hostname consists of no more than 15 characters, TCP/IP is protocol used. DHCP configured with one scope for each subnet. All Windows based computers are set up as DHCP clients.
Required results:
1) Every Windows based computer on each subnet must be able to access the Windows NT Server computers by computer name.
2) Every Windows based computer on each subnet must also be able to receive its IP address from the DHCP server.
Optional:
1) All UNIX systems should access by hostname any Windows NT Server computer that is set up as an FTP server.
2) All Windows based computers should access by hostname any UNIX computer that is set up as an TELNET or FTP server.
Question 1:
Proposed solution:
1) Set up network routers and forward DHCP broadcasts to all subnets
2) Install Wins server on the network
3) Install DNS server and configure it for name resolution
4) something else that is meaningless for the problem
Question 2:
Proposed solution:
1) Set up network routers and forward DHCP broadcasts to all subnets
2) Install Wins server on the network
3) Install DNS server and configure it for name resolution
4) Set up DHCP server to supply all DHCP clients with the IP address of both the WINS sever and the DNS server.
5) something else that does not meet the problem
Proposed Solution:
Like Scenario 1, additional
2) On the WINS server, make static mapping entries for UNIX computers.
3) On the DHCP server, exclude the UNIX computers'IP addresses from scope
Question 3:
Proposed solution:
1) Set up network routers and forward DHCP broadcasts to all subnets
2) Install Wins server on the network
3) Install DNS server and configure it for name resolution
4) Set up DHCP server to supply all DHCP clients with the IP address of both the WINS sever and the DNS server.
5) On the DHCPserver,exclude the UNIX computers'IP addresses from the scope.
6) On the WINS server, make static mapping entries for UNIX computers
The options given for all the three questions were as follows
A) The proposed solution produces the required result and all of the optional desired result.
B) The proposed solution produces the required result and only one of the optional desired result.
C) The proposed solution produces the required result and none of the optional desired result.
D) The proposed solution does not produces the required result.
Thre were many questions related the following utilities. Generally you dont need to know the switches for them.
It was hard for me to find all utilities from the book I used so, This is for your easy refrance.
1) Purge the content of ARP Cache ARP -d
2) To see IP to MAC address resolution ARP -a / -g
3) To Add Static entry to ARP ARP -s
4) To view changes made to DHCP IPCONFIG /All
5) To collect the data in the Spreadsheet Performance Monitor or Chart of TCP/IP Statistics Performance Monitor or log file formate or with use of SNMP Performance Monitor
6) To redirect the print job to the net printer form UNIX or Windowse LPR
7) To View a Print job
From UNIX to NTprinter(Win) or
From NT (win) to UNIX printer LPQ
8) Need to configer Nt server TCP/IP to get above results printing service
9) To Clear the NetBios cache NBTSTAT -R (Case sens switch)
10) To show the Netbios cache NBTSTAT -c
11) To find the computer with duplicate IP address. NBTSTAT -n
12) To view list of allTCP/IP connections NETSTAT
13) The summery of IP & Ethernet Statistics NETSTAT & NET Monitor
14) To see the routing tabel on server NETSTAT-r & ROUTE
15) To clear all route ROUTE -f
16) To troubleshoot DNS problems. Host name resolution problems NSLOOK UP
17) To identify Path and time taken by Packet Through the routers TRACERT
18)To copy files from UNIX Server ftp
19)To access and run App on remote UNIX Telnet
20)Try connecting TCP/IP using computer Ping
21)To use NDIS 4.0 to capture frames from network datastreem,filtering. NET Monitor.

DNS Server types
Some of the books has not covered this content which is asked in the exam.
(1).Primary Servers: Get all data for the zone from locally stored files.All changes to a zone must take place at the Primary server.
(2).Secondary Servers: Get all information from another name server that is authoritative for the zone.This transaction is known as a"zone transfer"
(3).Master Server: A name server that provides zone information to the requesting secondary servers. This server can be either a Primary server or another secondary server.
(4).Caching Only Server: This type of server is not authoritative for any zone. It has no local zone files. It merely accepts and processes requests, storing results in its cache(which all name servers have) for future resolution.No "zone transfer"
(5).Forwarder: A forwarder is a name server configured to accept requests for name resolution from other name servers when resolution is unsuccessful.This is typically used within an intranet for name esolution outside of the zone.
You need to Know the different methods that Windows NT uses for name resolution. For
* * NetBIOS name resolution,
a helpful memonic is: "No Where But LA Has Diversity"
-- -- -- -- -- --
(NetBIOSname cache, WINS, Broadcast, LMHOSTS, HOSTS, DNS).
* * Host name resolution,
try: "Large Hard Drives Never Wear Black Lace"
-- -- -- -- -- -- --
(LocalHostName, HOSTS, DNS,NetBIOS name cache,WINS, Broadcast,LMHOSTS)
Know how the various node types change the default methods.
3 more to go,
Thank U for help and advise.
May god bless you all, Best of luck ! ! !
