35: You are able to connect to an FTP server by using its IP address, 202.12.127.7, but not its domain name, "development". The HOSTS file reads:

               131.107.5.5              sales department                # Sales and marketing
               111.36.254.134        UNIX development            # UNIX department
               202.12.127.7            development                       # Programming

Why can’t you connect to the FTP server with the domain name, "development"?

A: The problem lies in the fact that "development" is resolved on the third line of the file, and not the fourth. You need to remember that multiple host names can be on a line, and where the first instance of the host name is found in HOSTS file, that is where the IP address will be resolved.

Caching Only Server Does not store a permanent zone list. Caches resolved queries so it can resolve a second query to the same name immediately. Useful when placed at the ends of a slow WAN connection, because they can answerresolver requests but do not require zone database transfers. .
Cache File Contains IP addresses of the root name servers in a file named cache.dns
SOA Record The Start of authority (SOA) record specifies the domain for which a DNS server is responsible. It also specifies a variety of parameters that regulate operation of the DNS server. Contains the 3 types of resource records, which are CNAME, MX, and PTR.
Reverse Lookup File This file contains IP address-to-hostname mappings that are used when a program or user has only the IP address of a remote computer but needs the hostname associated with that IP address. Reverse Lookup-records are used for IP address to name resolution in reverse lookup zones
Forwarder A DNS server that can communicate outside of the private network to resolve DNS name queries. Picks up broadcasts from clients and sends them to the DNS server.

Remote client must able to connect to shared resources on all computers on the company network.

Optional :
You want all data that is transferred accross the dial-up connection to be encrypted.
RAS must support two cuncurrent remote clients.

Proposed Solution :
a. Configure RAS to use a static address pool with two address for dial up networking clients.
b. Enable multilink on RAS server. Install PPTP on the RAS server and on the dial up networking clients.
c. Configure RAS to use DHCP to assign remote clients address.
d. Configure Dial-up networking client s to use a server assigned IP address.
e. Disable the Guest account on the RAS server.

A: Produces required and one optional results.

201: Three servers, 40 NTW, Single network. Router connect to the network to an ISP. All computers on your network are DHCP, WINS and DNS clients. WINS and DNS servers are DHCP scope option. RAS - two modems.

Required :
Remote client must able to connect to shared resources on all computers on the company network.

Optional :
You want all data that is transferred accross the dial-up connection to be encrypted.
RAS must support two cuncurrent remote clients.

Proposed Solution :
a. Configure RAS to use a static address pool with two address for dial up networking clients.
b. Enable multilink on RAS server. Install PPTP and use MSCHAP, and put check in encrypt data.
c. Configure RAS to use DHCP to assign remote clients address.
d. Configure Dial-up networking client s to use a server assigned IP address.
e. Disable the Guest account on the RAS server.

A: Produces required and two of the optional results.

202: All clients on your network use a single DHCP server. You have congiured the DNS address in the global scope. However, 1 client can't resolve host names. When you run ipconfig, you detect a different DNS server IP address. What are the possible causes? (choose 2)

A: Client has manually configured DNS address.
A client option w/ different DNS IP address has been created for that client.

203: Which 2 of the following NT services will register names with WINS when they initialize? (choose 2)

A: Server
Messenger

204: You have 3 NT Servers, 75 client computers that use NetBEUI. You want the client computers to be able to access a UNIX computer. The UNIX computer uses NFS. You do not want to add any new software. What device should you use?

A: Gateway

205: You have a TCP/IP network and want to track how many users connect to your 15 NT server machines and 5 routers. What utility do you use?

A: SNMP

206: You decided to install a DHCP Server on each of your network's 7 subnets. On each server, you place a scope of IP address for each subnet on another server. How can you provide DHCP services across the network when one DHCP server does not work?

A: Install BOOTP forwarding on each subnet router.

207: In a HOSTS file, there is an entry as below :

131.107.16.12 developer

Developer is on a remote subnet. You can ftp 131.107.10.12 on a workstation, but you can’t ftp developer. Why?

A: Host name is not developer

208: On a Class C network you have the following: Your network comprises of 3 segments with 300 clients each. To minimize number of subnets on each segment, what should you do?

A: Implement a subnet mask borrowing 3 bits.

209: A Windows 95 user complains that she cannot connect to any computers on her local subnet even when using their IP addresses. Seated at her computer, you ping 127.0.0.1 and receive a reply. Other users on her subnet do not report having any trouble. All client computers on the network are WINS-enabled. What is the most probable cause of the problem?

A: The subnet mask on the Windows 95 computer is incorrect.

210: Drag and Drop question with the following info. You have to match the subnet mask that will achieve the required number of hosts.

Network IP Address Required No of Hosts Subnet Mask
165.6.0.0 240 255.255.255.0
194.25.11.0 11 255.255.255.240
191.109.0.0 300 255.255.254.0
221.201.64.0 50 255.255.255.192

211: What utility do you use to test the connection to a remote Server on a TCP/IP network?

A: Ping

212: To transfer small data files without any notable overhead in a UNIX/NT environment. What would you use?

A. TFTP.EXE

212: You submit a TCP/IP print job from your UNIX computer to a remote Windows NT Server 4.0 computer acting as a TCP/IP Print Server. Five minutes later, the print job has not printed. How can you determine the status of the print job?

A: A Run the LPQ utility.

213: You have an NT server with two network applications. Each application has a hard coded an IP address. The first application has an address of 172.20.3.44 and the other has an address of 172.20.3.50. They are both class B addresses. What would be the best solution to get the applications looking at the same network?

A: Install one NIC and bind the two IP addresses to it.

214: Michael is planning a TCP/IP network that will be comprised of six subnets. All the computers on the network will be Windows-based. Which service should Michael install to provide for name resolution on his network?

A: WINS

215: Which file does a DNS root server use to connect to the Internet?

A: cache.dns

216: Which utility will help you find which machines are issuing DHCPNACKS?

A: Network Monitor

NOTE: The information in this study guide will be sufficient to pass the TCP/IP exam. However, if you want a fairly detailed definition of how TCP/IP works, there is an excellent presentation at http://www.3com.com/nsc/501302s.html.
