Scenario 1 (These Scenerios Came Up About Half Way Through) Network with 100 workstations and 20 UNIX

computers. UNIX computers never move,each Unix-hostname consists of no more than 15 characters, TCP/IP is

protocol used. DHCP configured with one scope for each subnet. All Windows based computers are set up as

DHCP clients. Required results: -Every Windows based computer on each subnet must be able to access the

Windows NT Server computers by computer name. -Every Windows based computer on each subnet must also

be able to receive its IP address from the DHCP server. Optional: -All UNIX systems should access by hostname

any Windows NT Server computer that is set up as an FTP server. -All Windows based computers should access

by hostname any UNIX computer that is set up as an TELNET or FTP server. Proposed solution: -Set up network

routers and forward DHCP broadcasts to all subnets -Install Wins server on the network -Set up DHCP server to

supply all DHCP clients with the IP address of the WINS sever = C)

Scenario 2 Network with 100 workstations and 20 UNIX computers. UNIX computers never move,each

Unix-hostname consists of no more than 15 characters, TCP/IP is protocol used. DHCP configured with one

scope for each subnet. All Windows based computers are set up as DHCP clients. Required results: -Every

Windows based computer on each subnet must be able to access the Windows NT Server computers by

computer name. -Every Windows based computer on each subnet must also be able to receive its IP address from

the DHCP server. Optional: -All UNIX systems should access by hostname any Windows NT Server computer

that is set up as an FTP server. -All Windows based computers should access by hostname any UNIX computer

that is set up as an TELNET or FTP server. Proposed solution: -Set up network routers and forward DHCP

broadcasts to all subnets -Install Wins server on the network -Set up DHCP server to supply all DHCP clients

with the IP address of both the WINS sever and the DNS -On the WINS server, make static mapping entries for

UNIX computers. -On the DHCP server, exclude the UNIX computers' IP addresses from the =B)

Scenario 3 Network with 100 workstations and 20 UNIX computers. UNIX computers never move,each

Unix-hostname consists of no more than 15 characters, TCP/IP is protocol used. DHCP configured with one

scope for each subnet. All Windows based computers are set up as DHCP clients. Required results: -Every

broadcasts to all subnets -Install Wins server on the network -Install DNS server and configure it for name

resolution -Set up DHCP server to supply all DHCP clients with the IP address of both the WINS sever and the

DNS -On the DHCP server, exclude the UNIX computers' IP addresses from the scope. -On the WINS server,

make static mapping entries for UNIX computers =A)

*You want to enable a server to work as a router. required result: routing must be possible optional results

dynamical routing enabled SNMP traps are to be sent to a SNMP - manager Solution Activate IP-forwarding

install PPTP install DHCP =C)produces just the required result

*You want to enable a server to work as a router. required result: routing must be possible optional results

dynamical routing enabled SNMP traps are to be sent to a SNMP - manager Solution activate IP-forwarding install

RIP install DHCP (some other services but not SNMP) =B)produces the required result and one optional (Mine

was send SNMP Trap instead of RIP Close enough…Still B)…..)

Troubleshooting *There is a net with the address 171.10.2.0 Remote clients cannot access a server in this net.

You run IPCONFIG and read: IP address 171.10.2.223 Default Gateway 171.10.2.1 subnet mask 255.255.0.0

NETBIOS node type h NETBIOS scope-ID (i.e. none) WINS Client enabled DHCP Client Why does this

configuration not work? =(Got one wrong and this Might Be the One)

*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?

*Why unnecessarily a machine is doing arp broadcast even when the target machine is in the same subnet while

other machines in the same subnet are not? = INVALID SUBNET MASK

*Following entries in a HOSTS-file: 192.168.5.7 UNIX developer #ftp server 192.170.8.15 developer #server With

'ftp developer' you can connect to the ftp server but not with 'ftp192.168.8.15'. Why? =FTP Address Isn`t

192.168.8.15 (watch for the wording of the answers..tricky)

A few more in this same vein..can do it this way but not that..just remember if ya can get to something one way

than your config is probably good(Gateway..IP…Subnet Mask) its most likely your name resolution…pdc

down(browsing)..wrong permissions or faulty entries in your hosts/lmhosts files..

*You want to monitor the NT Workstation performance from a Unix client. How will you do it? What Software

(utility?) at NT Workstation and at Unix host? =SMNP MANAGEMENT SOFTWARE ON THE UNIX =SMNP

SERVICE ON THE NT SERVER.

*One question asked how a third DNS server should be configured to resolve Internet names. Answers available

were: 1) Primary ….2) Secondary 3) Forwarder for other DNS servers 4) Forwarder for WINS

*DNS entry for a mail server=MX

*You plan a internetwork. How many NET-Ids do you need? (Choose two) one for each subnet one for each host

one for each host' s NIC one for each router' s interface one for each WAN - link

You have three subnets in which a single subnet is populated with 10 Laptop workstations and the other two

subnets with NT Workstations. You want the 1st subnet to be supplied with IP addresses(of course by DHCP)

with a lease acqusition period of 10 days.The other two subnets with 30 & 40 days lease period respectively. How

will you configure? =BY IMPLEMENTING ONE DHCP SCOPE FOR EACH SUBNET AND SPECIFYING THE

LEASE PERIOD AS PART OF EACH SCOPE'S ONFIGURATION.

Utilities *Clear the NETBIOS - cache =NBTSTAT

*Show the NETBIOS - Cache =NBTSTAT)

What utility can be used to run a command on a remote host? =TELNET

What is the utility to view who are all currently having TCP/IP connection with your Workstation? =NETSTAT

What is the utility to view what configuration changes the DHCP made at your workstation configuration?

=IPCONFIG /ALL

What is the utility to purge the contents of the arp cache? =ARP

what do you use to find the path a packet takes? =tracert

What to use to monitor ethernet & tcpip stats =netstat =network mon

what do you use to monitor TCP/IP stats since the last reboot? =netstat .exe

What utility for seeing the IP address - Physical address match of a an interface card? =ARP

what do you use to capture and examine Ethernet frames? =network monitor

what do you use to capture TCP/IP packets, log them and export to a spreadsheet? =performance monitor

*How to configure a RAS - server that directly accesses the internet and uses PPTP. Clients access the RAS

server via an ISP that is accessed with a modem. =PPTP filtering

Your NT Server in your office is connected via RAS connectivity to the Internet ISP Server through the ISDN

communcation. Now you want the Windows 95 workstation users in your internel subnet to get connected to the

ISP. How will you do that? =PPTP

Printing How will you configure the printer on the server, if the server will manager the printer? =INSTALL

TCP/IP PRITING SERVICE, CONFIGURE A LPR PORT FOR THE PRINTER AND SHARE THE PRINTER. (now

this is only two answers TCP/IP Printing is one and Configure LPR port and share are combined into the

other..there was one that just said share the printer…wrong..`manage` the printer means configure the LPR port

but you still have share)

You want the Unix member workstations to print jobs at the NT print server connected print device. How will you

configure?(tricky wording on thses) =INSTALL TCP/IP PRITING SERVICE AND SHARE THE PRINTER.

You want the Windows based machines to print at a UNIX-Network printing device connected to a NT Print

Server. How will you redirect the jobs to the net printer?(tricky wording on thses) =LPR

You want to send the print jobs to a UNIX workstation from the windows based machines.Which utility will you

use? =LPR

You want to view the print jobs that are sent to UNIX printer from a windows based workstation.Which utility will

you use? =LPQ Wins/LMHosts You are not able to ping the IP address of a remote host on another subnet using

Netbios name but through IP address.You can also ping the other hosts on that subnet using both ways.What

went wrong? =CLIENT NOT USING WINS SERVER.

You have Subnet A, Subnet B and Subnet C. The Workstations in the subnet A&B uses the WINS in the Subnet

A. The Workstations in Subnet C uses its own. How will you configure to have the users of Subnet C and B to

browse themselves freely? =WINS REPLICATION.

You can ping the remote host using the IP address but not through netuse \\....\... Why? =LMHOSTS.

You don't want to resolve host names into IP address using a DNS which contains static entries in it.What will

you install in alliance with DNS to resolve IP address from a dynamically updated DNS database? =ENABLE THE

DNS FOR WINS RESOLUTION.

*A PDC and several BDCs in different subnets must be able to 'see' each other without using wins. =adequate

#PRE and #DOM - entries in their LMHOSTS -files.

*Three UNIX machines are to be stored in the WINS Database manually and what entry will you put at the WINS

configuration panel? STATIC UNIQUE ENTRY

*LMHOSTS questions presented a sample like this: 131.107.3.4 #MainServer #PRE 131.107.4.1 #Router1
