Subject: braindump 70-59
Hello, I passed the 70-59 TCP/IP with score 829 at 01/19/98, my first one. May thanks to the provider of this service, and the peoples brainsdumps, because they are very useful.
My braindump:
You should know the followings:
Nbtstat - NetBIOS Tool.
Netstat - Summary of the TCP/IP statistics data after the system started.
Network Monitor - Capture network frames real time and analyse them later with the Network Monitor.
Performance Monitor - Is able to log data and export them into a spreadsheet or a database. You can analyse the data with a database program, so you can find bottlenecks. If you want to log TCP/IP data you must install SNMP.
LPD
LPR - Client- and serverside
SNMP
Security items, need to have for IP-Monitoring
There were many scenario based questions, you have to find the problems.
- invalid Subnet Mask, invalid IP-Adresse, invalid Gateway or NetBIOS Scope.
- One Question: A machine can't ping on the local subnet, in my case there was a wrong subnet mask defined, the other possible case is a wrong IP-address.
- I had three very big scenario based question, in the scenario there were many subnets, with DNS, WINS, DHCP, Wins Proxy Agent, DHCP Relay Agents, Unix maschines, MS Clients and Server, what should I say with everything you can dream about, BUT NOT on an test nice to have.
Then there where required things and optional things to have and a solution. I selected every three question, with e) doesn't meet the requirements and doesn' t go, BUT as I read the solution exact, then I found in every solution an big mistake, or there was anything forgotten just like a DHCP, or a DHCP relay Agent. I think they wanted to test your overall view.
- difference between
- MX - Mail server entry
- Two subnets, on each subnet is a WINS located who is responsible for his subnet. And now the user form each subnet wanted to see all the computers form the other subnet. I selected the WINS should be replicated.
DHCP Relay Agent - WINS Proxy Agent - on which Computer should they be located, in which Subnet
Which File should be imported in WINS - The Lmhosts-File I selected.
A maschine with 3 network card is called - Multihomed
- know the different between the DHCP options, default, global and scope
- you should know the syntax
- I had an hosts file with some entries like the following
102.54.94.97 #rhino.acme.com
the mistake is the # in front of the host name
Browsing with the Lmhosts File
- in each Lmhosts-File on an Domain Controller should be the other Domain Controller for browsing, User Account updating and User logon.
AND at last my most important tip, bevor you start with the test just write the following table on a sheet of paper, because then you can very quick answer the subnetting and supernetting questions, I had four.
