MOC
Transcender Prep Exams for TCP/IP v4.0
My exam was similar to the Suresh s exam:
How a third DNS Server to function as a Backup server in an environment where there are already two DNS Servers acting as Primary and Secondary? CACHING-ONLY SERVER
How can you configure the third DNS Sever which is to be configured for supporting the load balancing of Primary Server and should not participate in Zone Trasfer Traffics? CACHING-ONLY SERVER
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 -d
What is the utility to monitor the Ethernet traffic and the TCP/IP statistics? NETSTAT -e -s
Which utility will you use to export the statstics collected to a spread sheat for future analsis? PERFORMANCE MONITOR
What utility will you use to construct a capacity planning on all statistical datas you collected? PERFORMANCE MONITOR
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
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? B-NODE or INVALID SUBNET MASK
What utility for seeing the IP address-to- MAC- address resolution? ARP
12)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 CONFIGURATION.
13)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
14)You want the Unix member workstations to print jobs at the NT print server connected print device. How will you configure? INSTALL TCP/IP PRITING SERVICE AND SHARE THE PRINTER.
15)You want the Windows based machines to print at a UNIX-Network printing device connected to a NT Print Se rver.
How will you redirect the jobs to the net printer? LPR
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. At the client only connect to the printer.
16)You want to send the print jobs to a UNIX workstation from the windows based machines.Which utility will you use? LPR
17)You want to view the print jobs that are sent to UNIX printer from a windows based Workstation.Which utility will you use? LPQ
18)You are configuring a IIS server on NT Server a which is going to be used as a FTP Server and also a WWW Server. How will you configure it for the Host record? CNAME ..... MAIL SERVER? MX
19)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 AND SMNP SERVICE ON THE NT SERVER.
20)You don t want to have trap messagees from unauthorized SNMP Hosts. How will you configure the SNMP agent workstation? "Community Name" and "Only Accept SNMP packages from these Hosts".
21)When you ftp a host name using UNC you get a "Bad IP address" message. What cou ld be the possible reason? HOSTS FILE.
22)You can ping the remote host using the IP address but not through netuse \\....... Why? WINS or LMHOSTS.
23)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.
24)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.
--------------------------------------------------------------------------------
26)You want a Workstation in Subnet A to browse and Communicate with the other workstation in subnet B. But you can t even though they have their own WINS Servers installed.What will you do? WINS REPLICATION.
27)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.
28)You have two WINS servers and you want them to participate in replication.The link is a 56kb Slow link.You also want the Replication to take place once in a day.In the display appellete the WINS at Subnet A is configured to replicate once it get 5000 entries with its push partner WINS at subnet B. The WINS at Subnet B is configured to replicate with its pull partner to replicate once in 24 hours. Just grade it.
29)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? WINS and ENABLE THE DNS FOR WINS RESOLUTION.
- 157.21.36.121 UNIX Product
157.51.25.110 Product developer
Above is a Hosts file entry.When you say "ftp product"&nbs p;you get attached to the ftp server. But when you say "FTP 157.51.25.110" you can t reach it.Why? INVALID FTP SERVER S IP.... You have to know how the HOSTS file works.....
How will you log on to a Domain controler which is in another domain and for that what entries do you require at your Workstation s lmhosts file? (PDC and BDC) #PRE #DOM
Why a workstation is not making a broadcast even when it can t resolve through other methods? P-NODE
My tips:
Know all the TCP/IP utilities: arp, netstat, nbtstat, ipconfig, tracert, ping - don t worry about switches, just know what they are each used for.
Know the differences betweem primary, secondary, fowarding and cache-only dns servers.
Know when WINS, WINS proxy, DHCP and DHCP relay should be used.
Know the NETBIOS name resoluition modes (h, b, m, p).
Know how push and pull replication works on WINS.
Know how to configure DHCP pretty well.
Know the syntax of both LMHOSTS and HOSTS.
Know when to use WINS and when to use DNS.
MEMORIZE the subnet table!
Valid Subnets ===> Subnet Mask
254 ===> 255
126 ===> 254
62 ===> 252
30 ===> 248
14 ===> 240
6&nbs p;===> 224
2 ===> 192
There are up to 5 questions and are easy if you know the table.
Don t worry about fancy subnetting formulas, save your self some time.
Know how to calculate the # of hosts per subnet ((2^#bits)-2), i.e. 255.255.240.0,11111111.11111111.11110000.00000000 = # of zero-bits = 12
So, ((2^12)-2)= 4,094 hosts.
Know how to use the route add command.
Know what lpr, lpd and lpq are for.
Know how to install a TCP/IP printer on NT.
Know how to configure a RAS server as a gateway to the internet and the clients on the network.
Learn the format of the LMHOSTS file(#PRE #DOM).
Know how WINS clients communicate with WINS servers and understand the WINS database replication process.
Be familiar with DHCP scope options and which can be overridden by the client. Understand how to make NT route packets, how to make NT dynamically update routes, and how to provide DHCP resiliency across routers.
Brush up on TCP/IP printing using lpr.
Be familiar with SNMP installation on NT.
Be familiar with Hosts IDs and Networks IDs.
Know which troubleshooting tools are used for which purpose.
I have a lot of questions where the SUBNET MASK was invalid, be careful...
Know when Network monitor is required and when Performance monitor is required!!!
Subnetting questions were easy once you understand subnetting and then understand the table.
Know troubleshooting tcpip connections, when subnet mask incorrect, when ip address incorrect, when default gateway incorrect.
