a. Bus
b. Tree
c. Star
d. Cube
2. Which of the following operating systems will allow you to create a peer-to-peer network from a group of workstations? (Choose all that apply.)
a. MS-DOS
b. Windows 8.1
c. Linux
d. Windows 7
3. Which of the following components are not necessary to create a peer-to-peer network from a group of workstations? (Choose all that apply.)
a. Client operating system
b. NIC or motherboard with onboard NIC
c. Network media
d. Web browser
e. Nerwork operating system
4. What is the primary difference between peer-to-peer and client-server architectures?
5. True or False? On a peer-to-peer network consisting of four Windows 7 or 8.1 workstations, each user can individually control which of her local data files she wants to share with other users.
6. Which of the following could be shared as resources across a network? (Choose all that apply.)
a. Microsoft Word and other Office applications
b. Printers
c. Documents
d. Network interface cards
7. True or False? In a client-server network, it is possible to share documents between individual users' computers as you can in a peer-to-peer network.
8. You are the network administrator for a small company. When users take vacations, they would like to allow other users to update the files stored on their computers. Additionally, several users have complained that they have accidentally deleted important files on their local computer, and would like some way to recover them. How would you recommend that they store their files?
a. Make multiple copies on their local hard drive.
b. Store the files on the server, which is backed up nightly.
c. Make copies of the file on a USB thumb drive.
d. Burn the files onto a CD.
9. A very large organization might have thousands of servers. Do the benefits of client-server networks still apply to such an organization?
a. No, because managing so many servers is difficult.
b. No, because the organization can rely on alarge peer-to-peer network to share files instead.
c. Yes, because it is easier to manage thousands of servers than it is to manage the hundreds of thousands of workstations that such an organization might have.
d. Yes, because managing thousands of servers is no more difficult than managing a few servers.
10. In this lab, what kind of network service did you configure on your client-server network?
a. Management service
b. Mail service
c. Internet service
d. File service
11. Which two of the following issues make peer-to-peer networks less scalable than client- server networks?
a. Each time a new user is added, the peer-to-peer network cabling must be reinstalled between nodes.
b. Adding nodes to a peer-to-peer network results in diminished overall network performance.
c. Adding nodes to a peer-to-peer network increases the risk that an intruder can compromise a shared data folder.
d. Adding new resource-sharing locations and ensuring that all authorized users have access to new resources becomes less manageable as the peer-to-peer network grows.
Lab 2.2. Building a Simple Client-Server Network
Objectives
Client-server networks are found in all but the smallest organizations. Although client-server networks are more difficult to configure than a peer-to-peer network, they are more scalable and can grow larger than peer-to-peer networks can. S7ith more than a handful of computers, a peer-to-peer network quickly becomes unwieldy. In a client-server network, however, you can manage user accounts and network resources such as printers from a single machine. For instance, to change the printer used by all users on a peer-to-peer network, you would need to go to each machine and configure the new printer. Imagine having to do this on 500 machines! In a client-server network, however, you can typically change this setting on the server for all users.
The goal of this lab is to become familiar with the methods for establishing a simple client-server network. During this lab, you will be introduced to the hardware and software required to connect one or more workstations to a server. As part of the setup for this lab, both the server and the workstation need to be configured with an IP address. Computers and other network devices use the IP address to find other computers.
After completing this lab, you will be able to:
Build a simple client-server network
Add a Windows 8.1 or 7 client computer to a Windows Server 2012 R2 domain
Materials Required
This lab will require the following:
One computer named SERVERI running Windows Server 2012P.2, or an equivalent virtual image, with an Ethernet port or NIC, configured with an IP address of 192.168.54.1
SERVERI configured as the domain controller for the netpluslab.net domain
A user account named netplus in the Users group in the netpluslab.net domain on SERVER l
A second computer named WORKSTATION1 running Windows 8.1 or Windows 7, or an equivalent virtual image, with an Ethernet port or NIC, configured with an IP address of 192.168.54.2; this computer should not be configured as a member of a domain
Access to WORKSTATIONI as a regular user
Both computers should be connected either virtually or through a switch or home router
Lab 2.3. Troubleshooting Client Logon Problems
In this lab, you will troubleshoot a scenario in which a user cannot log on to the server. From a user's perspective, when they cannot log on to the server, the network is unavailable, no matter what the reason. However, the ultimate cause of the problem might be anything from a hardware failure on the server to an expired password.
When troubleshooting problems, you should attempt to be as methodical as possible. You can start by determining the scope of the problem. Is only one user affected, or are all users affected? Then determine if the user's computer (or the users' computers, if multiple users are affected) and the server have physical connectivity. Do all the NICs seem to be working properly? Is the switch functioning and is the network cabled properly? After establishing that physical connectivity is not the problem, determine whether the user's computer has network connectivity. Can you ping the server from the user's computer? After you have determined that network connectivity is not the problem, try to determine if the application is functioning properly.
Keep in mind that being able to log on to a computer does not necessarily indicate that the network is functioning properly. Windows computers cache passwords for usernames, so that a user can still log on to a computer during a network outage.
In this lab, you will first verify that the network, the client computers, and the server are all functioning properly by logging on to two client computers. Then your instructor or another set of lab partners will do something to prevent at least one of the computers from logging on to the server. Your assignment will be to identify and solve the problem. After completing this lab, you will be able to:
Follow a logical troubleshooting methodology to determine the nature of client connectivity problems.
Identify a network problem by interpreting the results of diagnostic utilities such as Ping and Ipconfig
