Hello All!!

First of thanks to God for putting me in a position to even be taking these test. Next off, BDH Websters, for this awesome site. Once you know the material, these braindumps and the Transcenders are all you need to pass the tests. Knowing the material and passing the tests are two totally separate things entirely. I studied the braindumps and did one transcender in one day, then reviewed a little more, took a transcender another day, and then took the last transcender the day of the test. Total study time is something like 1-2 hours a day + transcenders. Brain dumps and transcenders, braindumps and transcenders, braindumps and transcenders are all you need to pass (but not necessarily know anything!!). You found the braindumps, now go buy the transcenders or find some transwhatevers at alt.binaries.warez.nt and use those. This method got me a 931 on TCP/IP.

Here��s my tcp/ip subnetting chart

n 1 2 3 4 5 6 7 8
D 128 64 32 16 8 4 2 1
SN Mask 128 192 224 240 248 252 254 255
# of SNs 0 2 6 14 30 62 126 254
# of Host ID��s Class A 2^(24-n)-2            
  Class B 2^(16-n)-2            
  Class C 2^(8-n)-2            

 

N= # of bits borrowed

D = # valid host id ranges begin with and is a multiple of. Ie D -2D is one subnet, 2D - 3D is another until XD = SN mask which is invalid.

SN Mask= Subnet mask. This will be the mask of your subnet. Ie. Class A = 255.SNMask.0.0 Class B= 255.255.SN Mask.0, Class C= 255.255.255.SN mask.

# of Subnets = how many subnets you need. Pick the # that is greater to or equal to the # of subnets that you need.

# of host IDs = Use these formulas to figure out whether or not you will have enough host ids after subnetting.

Here��s how to memorize the table.

  1. Write out 1-8 across the top of the page. That is # of bits borrowed.
  2. Under 8 from left to right, write out the unforgettable bit numbering scheme
  3. Under 128 write 128. Add 64 to 128 you get 192. Basically, add the D of the next column to your current column.
  4. For # of SNs, remember 0, 2, and 6. That will help you remember the formula 2x+2 where x is the number of SNs in the previous column.
  5. For host IDs, know that in Class A you only have 8 bits for network ID therefore only 24 for host IDs, if you borrow bits you will have less therefore 24-N. It��s the same logic for class B and Class C. �V2 from the result to exclude 0 and 255.

Here are a few questions I "remember" from the test. I thought that 1-19 were the most challenging. Number 20-48 were gimmes, and 49-58 were not so difficult but required some thought. Here are a few from 1-20.

  1. You use NT explorer on your NT Workstation and cannot connect to a server on a different subnet. All other computer s on your subnet can connect to the server. You use network monitor and you see that everytime you try to connect your workstation broadcasts an arp request for the servers IP address.
  1. Workstation has invalid gateway
  2. Workstation has invalid subnet mask
  3. Workstation has duplicate IP number
  4. Workstation doesn��t support wins.

I chose "b" because I figured that the wks would send the req. to a default gateway if it knew the request was for a diff. Subnet. I can��t be "a" because if the request was known to be remote, it would send it directly to the gateway and wouldn��t need to arp, and then why arp the server unless you think the server is on your subnet.

  1. You have a workstation that does not use DNS. It uses a HOSTS file. The HOSTS File has this entry (and a few others that are irrelevant):
        1. developer
  1. Host name assigned is not Developer.
  2. Host file does not contain the FQDN for the workstation.
  3. The Host file on the workstation is not returning the correct IP address for the server.
  4. The Host file on the workstation does not have a FQDN for the server.

I chose "a" because I knew that the IP number is correct if I can connect to the proper server using IP number. That only leaves the host name to be questionable. FQDNs are not necessary if the systems are on the same network. The Host file is a text file and is NOT case sensitive even though UNIX names are, it doesn��t matter for windows.

  1. Your Network ID is 142.170.2.0 Your Default gateway is 142.17.2.1 Your users cannot access the server. What��s wrong? You type in IPCONFIG /all at you get:
  1. Subnet mask is wrong
  2. NetBIOS scope ID is wrong
  3. NetBIOS Node type is wrong
  4. IP Address is out of the subnet��s range.

I chose "a" because there is nothing to do with NB scope IDs or Node type necessarily. If there were it would be mentioned in the question. The IP address is not out of range given this current situation unless the subnet mask is wrong. In this scenario, everything is on the same network.

  1. From you NT workstation you run ftp xx.yy.com and you connect to a remote server. When you use NT explorer you cannot connect. Why?
  1. Your workstation is not configured to use DNS.
  2. Your workstation has no default gateway.
  3. The server has no default gateway.
  4. The server is not configured to use wins.

I chose "d". It cannot be "a" because NT explorer doesn��t need DNS. It can��t be "b" because the Default gateway was used to run FTP. The server must have a default gateway to have returned an answer from ftp, or is that directed? In any case, the browsing service wouldn��t detect the server if the server hasn��t registered with the master browser and NT explorer uses the browse list.

Like I said, I thought that these were the more difficult ones, so like everyone else says, DON��T TRUST MY ANSWERS!!!!! Look it up for yourself.
