70-059TCP/IP 4.0 试题回顾（7）

person one ：

How I did it and what percentage each played in the success of the exam:
Transcender: 50%
Exam Cram: 15%
NT Resource: 5%
Brain Dumps: 25%
Hands on: 5%
I charted out the subnet matrix (only class C hosts) and then when I got a question concerning a Class B address I calculated the B hosts real quick with the calculator (took 30 seconds and I was way ahead on time)
Lots of folks make this step a lot more complicated than it is. If you can remember 192 - 2 - 62 everything else is a mathematical progression from there. To get the amount of B Hosts just take the number of C Hosts (not VALID C hosts, all C Hosts, ie. 64 not 62) and multiple by 256 and subtract 2. To get number of A hosts take C hosts and multiply it by 256 and 256 again and subtract 2. Simple huh?
Now there were no questions with regard to A class hosts so don t bother with that.
Also as everyone has said, no switch questions for any utilities. Another thing to note, if you are stuck on not being able to figure out the tough stuff like ANDing and figuring out whether two addresses are on the same segment etc. Don t fret, unless you are looking for a perfect score, there is maybe 1 question where this info is relevant. And don t feel bad if you can t do it under pressure in the real world there are IP calculators! Remember these tests are more geared toyour ability to implement and troubleshoot correctly after all isn t that what we do the most of?
Other info: This test is VERY Microsoft biased so if you know EVERYTHING there is to know about TCP/IP and don t know jack about WINS you will FAIL! There are more WINS questions then there are DNS questions!!
For those of you who use Transcender a lot, did you ever notice how after you have taken a Transcender test four or five times you see and check the answer without having to read the question?, well I used the TCP/IP Beta Transcender and it isn t like that, I had to read and struggle over the majority of the questions each time, before the test I was scoring high 800s low 900s and could never get a perfect score. This test is NOT harder than Networking Essentials. You can pass this test with the strategies you read here and in other brain dumps. Fortunately you will find that all the other dumps have covered most everything on this test, the one question I got that made me say "What the heck?!?!" was this:
Which program would you use to execute a program remotely on a Unix computer:
A. LPQ
B. LPR
C. FTP
D. Telnet
The one you were expecting wasn t a choice was it? Well the answer is D. Telnet. Thats the only on that threw me a bit.
There was a ROUTE ADD question with an exhibit that was too complicated to re-draw and too annoying to flip back and forth with, I skipped it and came back to it, here is how to remember ROUTE ADD:
ROUTE ADD > with a mask of this use this Gateway
Strangly I had no questions on resolution order (ie. Name cache, WINS, Broadcast, LMHOSTS, HOSTS, DNS) someone said to remember the phrase "Can We Buy Large Hard Drives" to remember the order.
Did have one on Netbios resolution:
The question was "you want WINS to resolve before Broadcast" which the answer is H Node.
Know when you need DHCP Relay and WINS proxy and when you don t.
