Instructions
After exploring the higher-layer transport protocols, you would
like to know how TCP/IP keeps track of all the different
sessions on a typical networked PC. You decide to examine the
protocols, ports, and processes involved in the typical browsing
of a Web site.
Task 1:Start with a description of the function of a TCP or UDP
port.
Task 2: Match the following port numbers to the appropriate
protocols.
Port 20
Port 21
Port 22
Port 23
Port 25
Port 69
Port 80
Port no
5. Port 137
Port 138
Port143
Port 443
Note: Some protocols use more than one port number.
Application
Port
SMTP
TFTP
FTP
HTTP
HTTPS
POP3
IMAP4
SSH
Telnet
Hint: Windows lists all of the well-known ports and protocol
services that are associated with them in a document named
"services." Access this list in Windows 7 by opening Notepad
(Start I All Pro- grams I Accessories I Notepad) and navigating
to c:windowssystem32driversetc. Change the view from
"Text Documents (*.txt)" to "All Documents(*.*)" to view and
open the services document.
6. Task 3: The services document is a static list of well-known
ports on a Windows PC. You will seldom if ever see all of these
endpoint ports open or active at one time. You can view a static
listing of the active ports using the netstat command-line utility.
netstat has a number of switches to customize the out- put of the
list. Run the netstat /?command and provide a description of
the following switches:
Switch
Description
netstat –a
netstat -b
netstat -n
netstat -o
Note: You'll be making heavy use of the help functions of
commands throughout the rest of the Lab in order to use some
of these more advanced functions! When in doubt, type the
command and add a space and/? to the end of the command! For
example: ping /?
Instructions
Having just finished the chapter on network naming in the
MikeMeyers'CompTIANetwork+ Guideto Managingand
Troubleshooting Networks textbook, you know that you are
going to have to implement DNS on the network lab's systems.
You want to get a jump on the setup, so you set out to define
DNS and WINS and examine how they are configured on the
client machines in use at the home office of ITCF.
7. Task 1: Describe the function of the DNS service on a TCP/IP
network.
Task 2: Local PCs cache any addresses resolved by DNS on the
hard disk. To view a display of resolved addresses cached on
your PC, you will use the command-line utility ipconfig
/displaydns. Open a command prompt and type ipconfig
/displaydns. What are your results?

Instructions – Part 1
In today’s lab, you will be working with common commands on
your windows workstation to view the network configuration.
8. Task 1: Run the IPConfig command and understand the output.
Log in to any available networked Windows computer. Select
Start | Run or just Start, type cmd, and press enter to open a
command prompt;
From the command prompt, type ipconfig /all, and then press
enter. Fill in as much information as you can from your screen
into the table.
For a tip on what to include, check Lab Project 7.3 in your
textbook.
Task 2: Run the Netstat command and understand the output.
Start a command prompt at your computer and enter netstat –nr
to view its routing table.
Create a screenshot of the output and paste it into this document
under this task.
Under the pasted screenshot, briefly explain what each column
9. is for.
CIS 1130Building an Ethernet Patch CableEthernet Basics
Learning Objectives
In this lab, you will research a TIA/EIA 568B patch cable.
When you have completed this lab you will be able toIdentify
proper orientation of RJ-45 connectorsIdentify the wire pairs of
a UTP patch cable according to the specifications of the
TIA/EIA 568B standard

Instructions – Part 1
The TIA/EIA 568B standard defines the arrangement of 4 pair
UTP cabling into RJ 45 connector. In purchasing commercial
premade cables the emerging standard is 568B.
Task 1: Using the Internet conduct a search for the TIA/EIA
568B standard wiring diagram. There are many sites that offer
color coded diagrams for wiring straight through patch cables.
Using your color coded diagram record the proper color wire for
each of the pins of the RJ 45 modular connector when
assembled using the TIA/EIA 568B standard.
Pin 1:
Pin 2:
Pin 3:
Pin 4:
Pin 5:
Pin 6:
Pin 7:
Pin 8:
10. Optional:
When possible in class we would make cables using these
standards. Depending on this course format, that may not be
possible. However if you have an extra UTP cable available you
can examine or disassemble it to compare the concepts and
layout of the pairs.
Learning Objectives
In this lab, you'll examine the standards and technology of
1000BaseT, 1000BaseSX, and 1000BaseLX Ethernet. When you
have completed this lab, you will be able to
Define the 1000BaseT Ethernet specifications, requirements,
and limitationsDefine the 1000BaseSX and 1000BaseLX

limitationsRecommend Gigabit Ethernet NICsDetermine
appropriate use of fiber-optic Ethernet based on application
Instructions – Part 2
Your client is building a new regional complex consisting of
two physical buildings. One building will house all of the
administrative departments. The other building, located
approximately 900 feet away from the administrative building,
will be a large, garage-like structure where the inspection of
automobiles will be conducted. The professional installers have
submitted a proposal that has been accepted, outlining the
following parameters:
The proposed cabling for the internal office space of the
administrative building is Category 6 UTP. The administrative
network will need to support 75 to 100 devices (servers,
computers, and printers).
The proposed cabling for the internal area of the inspection
building is Category 6 UTP. The network in the inspection
11. building will need to support 25 to 40 devices (computers and
printers).
For the backbone between the two buildings, the proposal is
single-mode 12-fiber optic cabling.
Using this general information, follow Steps 1 through 4 to
develop an implementation plan for the new site. The design
should take advantage of the Gigabit Ethernet technology.
