Question

A project that involves a complete Windows upgrade for an organization. All of the organization's PCs are being upgraded with Windows 7 and all of the servers are being migrated to Windows 2008. Halfway through the upgrade, Sally is ahead of schedule and under budget when she discovers that there is a compatibility issue with several major printers throughout the organization. With research, she finds that 64-bit drivers are not available for the printers the organization currently owns. Explain the network engineering life cycle and identify the stage in which Sally made her error

Answer 1

Cycle (NLC) provides a comprehensive framework against that network managers will build crucial choices, whether or not in moments of immediate crisis or for long-range coming up with.

The NLC defines a spread of desires that need a range of methodologies and tools for network performance management through observation, mensuration, Assessment and identification (MMAD). every part of the NLC has its own necessities which will generally be met with a even handed choice of tools and assessment solutions.

The major phases are:

• Business Case
• Requirements
• Request for Proposals
• Planning
• Staging
• Deployment
• Operation
• Review

Each part of the everyday Network Life Cycle needs some extent of attention to MMAD. In fact, the degree to that every part is correctly disbursed defines the probability of success of resulting phases.

To illustrate the importance of every part of the Cycle, think about that some networks area unit made with very little or no Staging part -- the preparation part from one service to a different is created "over the weekend" with fingers crossed. The success of the preparation depends on a very giant expenditure within the coming up with part -- and therefore the risk for lack of a radical Staging effort is assumed by preparation and even Operation. this might be affordable since the value of a Staging part is wide, each in terms of cash and time gone.

Let's look additional closely at the small print of every part of the NLC to spot the tasks involved:

Business Case

• Identify desires
• Define advantage
• Define objectives
• Establish risk tolerance
• Assign budget

Requirements

• Define scope and bounds
• Create base of use-cases
• Establish technical criteria
• Detail high-level necessities
• Generate performance specifications

Request for Proposals

• Review technologies
• Design solution(s)
• Do risk analysis
• Generate proof-of-concept
• Select implementation target

Planning

• Define project
• Assign responsibilities/roles
• Define milestones/deliverables
• Assign resources
• Identify dependencies
• Deployment/cutover ways
• Contingency coming up with

Staging

• Implement take a look at network
• Perform simulation
• Perform stress tests
• Apply range-of-use applications
• Identify installation/configuration problems
• Identify maintenance problems

Deployment

• Pre-qualification in place
• Stress testing final installation
• Base-lining
• Cut-over
• Reality check (next morning)
• Recovery/fallback (as required)

Operation

• Post-qualification
• Monitoring
• Troubleshooting/diagnosis/remediation
• Maintenance and upgrading
• On-going support

Review

Compare performance to set up

Review timeline of desires

Projected needs/provisioning

Proposed revisions against modified necessities

Growth strategy

The specific MMAD tools and methodologies for every stage tend to overlap however area unit generally distinct. The balance of this guide offers a spread of answers that affect explicit tasks at intervals the NLC framework.

As you concentrate on the counseled best practices, tools, and methodologies, offer due thought to over simply your every day necessities. assume broadly speaking concerning the character of today's networks and the way every resolution applies in your case. positioning your network performance management practices with overall NLC objectives will build your life easier, expenditures additional responsible, and your success additional doubtless.

Sally problem has solved by these steps :-

1. Check to see if the correct printer drivers for your printer are located on the computer that is running a 64-bit version of Windows. You can also visit the Windows Update Web site or the printer manufacturer's Web site. If you cannot find the correct driver, continue to the next step.
2. Log on to the computer that is running a 64-bit version of Windows by using an account that has administrative permissions.
3. On the physical printer, use the device menus to print a configuration page. The printed configuration page typically lists the supported printer emulations. For example, the configuration page might list PostScript, PCLXL, or PCL as supported printer emulations.
4. On the computer that is running a 64-bit version of Windows, click Start, point to Settings, and then click Printers and Faxes.
5. Double-click Add Printer.
6. Click Next.
7. Click Local printer, click to clear the Automatically detect and install
8. check box, and then click Next.
9. Click Create a new port, and then click Local Port next to Type of Port.
10. In the Port Name dialog box, type the path of the printer by using the following syntax:
11. \print server nameprinter name
12. Click Next.
13. In the Install Printer Software page, click the correct manufacturer under the Manufacturer column, click the name of a printer that supports the same printer emulation as your printer, click Next, and then click Finish. For example, if you have an HP LaserJet printer that supports Post Script (PS) emulation, try to locate another HP LaserJet printer model that has a similar model number and that supports PS emulation.
14. In Printers and Faxes, right-click the printer that you added, and then click Properties.
15. Click the General tab, and then click Print Test Page.
16. If the test page prints correctly, you have found a matching printer driver. If the test page is unreadable, you must find another printer driver or try another emulation type.
