22) Client A ------ router ------- Client B routers left IP-address is 200.64.64.1, its
right IP-address is 200.64.32.1. Why can Client A not access client B?
Its DG was 200.64.64.1
23) Host ------- router ------ server Class B net host's IP : ...82.2 routers left
IP-address is ...64.1, its right IP-address is ...32.1. SM 255.255.240.0 Why can the
host not access the server ->
With this SM the host is in a different subnet than it's DG.
24) Be aware of questions like: Which SM to use if you have 30 subnets and want
to maximize the numbers of hosts per SM in a given net ID. Or the other way.

without using wins.
adequate #PRE and #DOM - entries in their LMHOSTS - files.
28) You can ping a remote - client by using its IP-address but not by using its
name, whereas you can ping all the other hosts in the remote subnet by IP-address
as well as name.
client is neither WINS-enabled nor does he have an entry of your computer in its
LMHOSTS - file.
29) UNIX - hosts must be made able to use wins for name resolution. DNS is
already installed.
Use WINS resolution in DNS. (Be careful: They asked for WINS reverse lookup
in this context, which is wrong)

42) Using Windows NT Explorer, a Windows NT Workstation computer cannot
connect to a Windows NT Server computer installed on a different subnet. All
other computer can connect to this server. When you run Network Monitor, you
noticed that each time the workstation attempts to connect to the sever, the
workstation broadcast an ARP request for the server's IP address. What is the
most likely cause of the problem?
The workstation is configured with an invalid subnet mask.
43) Working at your Windows NT computer, you want to use Performance
Monitor to collect statistic from all TCP/IP traffic on the Windows NT server
computers on your network. What should you do?

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.

-----------------------------------------------------------------------------------------------
There are several subnets, each having its own DHCP-Server. Required result:
Each client receives its unique IP-address automatically
Optional result: DHCP - server must work even if one of them is down
a) Proposed solution:
Configure each DHCP-server to use the scope of another server as well
-> does not work; double IP-addresses possible
b) Proposed solution:
Install a DHCP-server that covers all the IP-scopes of all subnets
Do the same with all the other DHCP-servers
-> does not work, double IP-addresses possible
-----------------------------------------------------------------------------------------------
You have a domain spanning across three subnets.You want the clients in all the 3
subnets to be able to communicate and browse each other. How will you do that?
You install and configure an NT Server to be put in the middle of three subnets.
Required: It should be made to act as a router.
Optional: IP router and should be made to dynamically update its routing table
whenever routers are added and removed from the network. That machine to be
able to supply IP address to all the machines belonging to the three subnets. Also
you want a NT Workstation to be sent a trap message across the network.
>Configure the Server to act as router.
>Enable IP Forwarding.
>Implement the DHCP Server on the NT Server.
>Configure RIP.
