微软70-059TCP/IP4.0试题回顾（3）

I found reading alot of different material rounded my knowledge the DNS and WINS. Subnetting was easy simple questions if you know the tables:

mask # of subnets Bit interval # of hosts

192 2 64 62

224 6 32 30

240 14 16 14

248 30 8 6

252 62 4 2

254 126 2 -

255 254 1 -


128 + 64 + 32 + 16 +8 + 4 + 2 + 1

/ / / / / / /

192 224 240 248 252 254 255

I passed this monster with 827, really alot of DNS, WINS and DHCP.

Know the utilities:

ping
ipconfig/all/renew/release
nbtstat -n,-R,-c
netstat
route print
tracert
arp -s,-a,-g,-d
lpq
lpr
Performance Monitor and Network Monitor, know the difference between which will capture frames (Ethernet) and which will chart or log data to be viewed thru spreadsheet.

You need to know Netbios Name Resolution and Host name resolution

How to integrate WINS and DNS.

How to enable DNS for WINS resolution.

DHCP can only integrate with WINS if you specify the 44/NBNS server, and /46NBT node type

Know the #PRE #DOM #INCLUDE from lmhosts-file

Exclude UNIX clients from any DHCP scopes

The cache.dns file contain's name to-IP-addressing information for the Internet's root DNS servers.

For routing you need to enable IP forwarding.

RIP for IP effeciently solves problem of having to update routing tables.

For DHCP to assign IP addresses to a remote subnet, a DHCP Relay Agent needs to be set up on router in between subnets to broadcast requests, or DHCP servers must be on both subnets.

Know the problems when you have an LMHOSTS file and you can remove the # signs out, example:

147.68.56.54 #APPServer

147.68.22.34 #Dserver

147.68.57.87 #3server
