Answer: First, is the network cable plugged in? (physical layer) Does the computer in question have a valid IP address? Can the default gateway be successfully pinged? (testing LANA IP connectivity) Looking at the NICE and/or the switch, is the link light on? (data-link) Can the DNS server be successfully pinged? (testing IP connectivity) Is there a firewall in the network? If so, is the firewall correctly configured? (network layer on up to application) Do you know the format of the file?Do you have a program installed which can view the file? (presentation layer) Try browsing a different web site. Can your browser open a different website? Question: Use the OSI model to explain how an email message from you gets read by the recipient on his/her computer. Answer: Student should describe the data movement of the message in the network applying the theory of the OSI model. The satisfactory answer would demonstrate how the message is initiated from the computer, passed down the 7 layers, and how it is modified in each layer.The student should include how the modified message is transmitted, received by the recipient's computer and reconstructed.
Question: What is the OSI model? Answer: A brief explanation of the main purpose of the model (standardize the immunization flow among various technologies and products by different manufacturers) and the name of the seven layers: 7 Application, 6 Presentation, 5 Session, 4 Transport, 3 Network, 2 Data Link and 1 Physical. TOPIC 3: SOHO Broadband Question: A small law office is equipped with a broadband service.The office network has recently encountered various symptoms of degraded services. Some individuals are not able to access data from the file server hosted in house from time to time, while some others are not able to access the email and database through the Internet occasionally. How do you propose to determine the cause and correct it? Answer: The answer should incorporate a logical analysis to identify the exact failing points and use specific diagnostic methods/tools to determine the causes.
Based on the diagnosis, the issues could be related to the unstable LANA service provided internally or caused by the unstable broadband service provided by the vendor. The student should at least explain the detailed diagnostic procedures for each, and recommend an effective remedy accordingly. Question: Design a broadband solution for a home network that will accommodate access from multiple servers, computers, printers, TV's, phones and mobile devices for the home entertainment and data storage/sharing as well as telephony services. ND service provider, and render a wiring design based on the floor plan of a typical home and the location of each specific device, determining the type of media and interconnection devices, including wired and wireless, and the type of storage and file sharing solutions for entertainment and data services with necessary security controls.
Question: Describe popular broadband solutions available to consumers in today's market. Answer: Brief definition of broadband technologies, such as DADS, Cable Modem, and Satellite feed.A comparison and contrast of these technologies will be a plus. TOPIC 4: TCP/IP Question: A user reports she cannot access the Internet. Describe some of the tasks one would perform related to the TCP/IP protocol in order to troubleshoot this problem.
Answer: Ensure the user's computer has a valid IP address assigned. This can be done through the GUI (Network Properties) and the command prompt (using the upcoming [all command). Then ensure that the user can ping the domain server she is trying to reach (Ex: ping www. Yahoo. Mom, etc. .
Use ARP and RAP for resolving the address of the computer the user is trying to reach. Question: Protocols within the TCP/IP suite correspond to logical ports on a computer. How can one determine which ports within TCP/IP are open or have established Answer: Open the command prompt and type "neatest - n" and press Enter. The result is a tabular view of the ports that are open, have established connections, or are listening; along with the corresponding port addresses. Question: Define in basic terms, the TCP/IP suite of protocols.
Answer: TCP/IP stands for Transmission Control Protocol/Lenten Protocol. The TCP/IP suite of protocols is a collection of protocols (communication rules) needed to be installed on any computer or device connected to the Internet. TCP/IP is a connection- oriented suite of protocols which is devised by the Department of Defense; and was first used in a network known as ARPANET. Topic 5: Client-Server Question: A new employee for Acme, Inc. Is unable to login to the network from her desktop machine.List at least 3 possible reasons that would explain this situation? ; Possible Reasons: ; User Account has not yet been created ; No connection between client and server (I.
. Bad NICE, cable, etc. ) ; Client is not connected to the domain ; User is using incorrect credentials ; User is attempting to login to the incorrect domain ; The domain server is down Question: How does one connect a client (such as Windows 7 Professional) to a Windows domain? How does one verify that the computer is Joined to that domain?Answer: As an administrator, access the System in the Control Panel, change the computer name, domain, and workup settings, select Network ID on the computer name tab, enter the existing domain and Join. One may verify by determining if the imputer name is visible within the domain's Active Directory, or running unspoken, Question: What is a domain? Answer: A domain is a collection of computers networked together in such a way that all the computers do not have the same level of authority.
One computer (the domain controller-DC) has most of the authority and performs user-authentication; among other tasks. The DC can also serve as one or several servers in the network such as DDCD, DNS, File and print, etc. Topic 6: Windows Server Question: Users on a Windows server network are reporting that they can't access external Websites nor receive external emails. They are able to use the networked printers and access internally hosted files. The router that connects to the ISP may be pinged from the workstations.
The Websites in question are accessible from a smartened via the G network. Analyze the process one would adopt to troubleshoot and suggest the possible cause. Please include the server version in your answer. Answer: (Hint: The DNS service for your network could be down). Question: Explain how to configure a Windows Server for a small business network so that it may provide reliable logical connectivity among clients, printers, mobile vices, and any other networked devices. Please include the server version in your answer.
Answer: (Hint: this requires the correct setup and configuration of the DDCD service. ) Question: Identify the functions a Windows Server could provide for a small business / home office environment. Please include the server version in your Answer: Example services include: file sharing, print sharing, active directory to control user authentication and authorization, application server, DDCD (to assign IP addresses) and other related services. Topic 7: Active Directory Question: A user is unable to login on to desktop connected to a Windows Server 2008 domain.
Assuming that the hardware is functioning, connected, and configured properly, explain in detail how one would go about determining the cause of this user's difficulty. ; Check to see if the user is typing in the credentials correctly. ; Check to see if the workstation is connected at the IP layer ; Check to see if the workstation is indeed part of the domain ; Check to see if the user can login to the domain from a different workstation Question: A health insurance company recently hired several new employees in arioso departments (e. G. Counting, benefits, management, and referral).
Explain the steps a network administrator would need to perform on the server to allow these new employees to gain access to network resources. ; Create the users account with surname and password ; Assign the users to the appropriate group(s).
